thank you 43 00:01:45,270 --> 00:01:42,399 john for the introduction well i'm 44 00:01:49,190 --> 00:01:45,280 proceeding to share my screen 45 00:01:52,310 --> 00:01:49,200 i'm alex alvarez and i'm going to 46 00:01:55,590 --> 00:01:52,320 present the preliminary results of a 47 00:01:58,469 --> 00:01:55,600 series of bioinformatics analysis 48 00:01:59,990 --> 00:01:58,479 that a concern 49 00:02:02,389 --> 00:02:00,000 concerning 50 00:02:10,309 --> 00:02:02,399 protein that might be involved in the 51 00:02:13,589 --> 00:02:11,830 it is a 52 00:02:15,430 --> 00:02:13,599 a popular belief 53 00:02:18,470 --> 00:02:15,440 especially in 54 00:02:19,350 --> 00:02:18,480 some cultural and folkloric traditions 55 00:02:22,550 --> 00:02:19,360 that 56 00:02:23,830 --> 00:02:22,560 psychic abilities may run in families 57 00:02:26,070 --> 00:02:23,840 and 58 00:02:28,470 --> 00:02:26,080 fortunately we have 59 00:02:30,869 --> 00:02:28,480 evidence of different kinds 60 00:02:32,869 --> 00:02:30,879 that support this idea 61 00:02:36,869 --> 00:02:32,879 this comes from 62 00:02:38,390 --> 00:02:36,879 different esp studios 63 00:02:39,750 --> 00:02:38,400 from a 64 00:02:42,229 --> 00:02:39,760 service 65 00:02:44,630 --> 00:02:43,350 there is 66 00:02:47,030 --> 00:02:44,640 one 67 00:02:48,830 --> 00:02:47,040 pedigree analysis which is an analysis 68 00:02:51,270 --> 00:02:48,840 of the family history of different 69 00:02:55,030 --> 00:02:51,280 people this was 70 00:02:56,949 --> 00:02:55,040 done by sharokin in scotland 71 00:02:58,910 --> 00:02:56,959 and she 72 00:03:01,509 --> 00:02:58,920 interviewed around 73 00:03:04,550 --> 00:03:01,519 130 individuals 74 00:03:06,630 --> 00:03:04,560 that claimed to have an ability called 75 00:03:08,390 --> 00:03:06,640 second site this is a 76 00:03:11,670 --> 00:03:08,400 kind of 77 00:03:13,190 --> 00:03:11,680 it's like some sort of clairvoyance and 78 00:03:16,229 --> 00:03:13,200 mixed with 79 00:03:21,830 --> 00:03:18,630 and it's a typical ability 80 00:03:24,789 --> 00:03:21,840 in the scottish people 81 00:03:26,229 --> 00:03:24,799 mainly in the highlands of scotland 82 00:03:29,509 --> 00:03:26,239 so she 83 00:03:31,430 --> 00:03:29,519 found a consistent pattern across 84 00:03:32,470 --> 00:03:31,440 all of the individuals that she 85 00:03:33,270 --> 00:03:32,480 interviewed 86 00:03:34,789 --> 00:03:33,280 and 87 00:03:36,650 --> 00:03:34,799 proposed that 88 00:03:38,070 --> 00:03:36,660 this ability 89 00:03:39,750 --> 00:03:38,080 [Music] 90 00:03:41,670 --> 00:03:39,760 adjusted to an 91 00:03:45,190 --> 00:03:41,680 autosomal dominant 92 00:03:48,070 --> 00:03:45,200 model of inheritance this means that 93 00:03:49,430 --> 00:03:48,080 whatever is this trade it is not 94 00:03:51,910 --> 00:03:49,440 associated with 95 00:03:54,309 --> 00:03:51,920 sexual chromosomes 96 00:03:55,830 --> 00:03:54,319 and finally we have 97 00:03:58,550 --> 00:03:55,840 but i think it's the 98 00:04:03,429 --> 00:03:58,560 most striking evidence so far 99 00:04:09,350 --> 00:04:07,830 in which a team led by helani 100 00:04:10,470 --> 00:04:09,360 found a 101 00:04:18,390 --> 00:04:10,480 gene 102 00:04:22,069 --> 00:04:20,870 that uh well dejean has 103 00:04:23,749 --> 00:04:22,079 their 104 00:04:25,830 --> 00:04:23,759 specific variant in 105 00:04:30,390 --> 00:04:25,840 non-psychic people and 106 00:04:32,629 --> 00:04:30,400 another variant in psychic people 107 00:04:34,710 --> 00:04:32,639 so 108 00:04:36,710 --> 00:04:34,720 well before we 109 00:04:37,990 --> 00:04:36,720 proceed there's 110 00:04:42,230 --> 00:04:38,000 a couple of 111 00:04:45,350 --> 00:04:44,150 to show you 112 00:04:47,670 --> 00:04:45,360 in order to 113 00:04:50,070 --> 00:04:47,680 understand what's coming next the first 114 00:04:52,150 --> 00:04:50,080 one is the single nucleotide 115 00:04:56,469 --> 00:04:52,160 polymorphism 116 00:04:59,270 --> 00:04:56,479 or snip as it is abbreviated 117 00:05:01,350 --> 00:04:59,280 refers to a variation in a unique 118 00:05:02,790 --> 00:05:01,360 position of a 119 00:05:04,710 --> 00:05:02,800 nucleotide of 120 00:05:06,070 --> 00:05:04,720 any human gene 121 00:05:09,270 --> 00:05:06,080 and 122 00:05:11,350 --> 00:05:09,280 well in order to be considered a sleep 123 00:05:14,310 --> 00:05:11,360 it has to be present in at least one 124 00:05:15,670 --> 00:05:14,320 percent of a given population 125 00:05:16,870 --> 00:05:15,680 if 126 00:05:17,990 --> 00:05:16,880 because 127 00:05:19,430 --> 00:05:18,000 many times 128 00:05:21,350 --> 00:05:19,440 we can have 129 00:05:25,510 --> 00:05:21,360 specific variations both that are only 130 00:05:26,870 --> 00:05:25,520 present in a very few people 131 00:05:28,710 --> 00:05:26,880 so 132 00:05:31,110 --> 00:05:28,720 the snips are present in at least one 133 00:05:32,310 --> 00:05:31,120 percent of a population 134 00:05:34,230 --> 00:05:32,320 the other 135 00:05:36,710 --> 00:05:34,240 concept is the 136 00:05:39,990 --> 00:05:36,720 protein isoforms 137 00:05:42,710 --> 00:05:40,000 a protein isoform is a variation of a 138 00:05:47,909 --> 00:05:46,310 that is encoded by the same 139 00:05:48,950 --> 00:05:47,919 gene 140 00:05:50,070 --> 00:05:48,960 in this case 141 00:05:53,430 --> 00:05:50,080 we have the 142 00:05:56,070 --> 00:05:53,440 gene the dna which is first 143 00:05:57,670 --> 00:05:56,080 partly transcribed into three messenger 144 00:05:59,670 --> 00:05:57,680 rna 145 00:06:02,870 --> 00:05:59,680 and we have two types of gradients the 146 00:06:05,590 --> 00:06:02,880 coding regions which are the 147 00:06:07,909 --> 00:06:05,600 boxes and the non-coding ones which are 148 00:06:11,430 --> 00:06:07,919 the black lines so 149 00:06:15,189 --> 00:06:11,440 through alternative splicing which is 150 00:06:16,950 --> 00:06:15,199 a way of processing this 151 00:06:18,710 --> 00:06:16,960 piece of 152 00:06:22,070 --> 00:06:18,720 rna 153 00:06:23,270 --> 00:06:22,080 we can have different uh 154 00:06:26,070 --> 00:06:23,280 pro 155 00:06:27,029 --> 00:06:26,080 splice and rnas 156 00:06:29,510 --> 00:06:27,039 and 157 00:06:31,990 --> 00:06:29,520 this will be translated into 158 00:06:34,550 --> 00:06:32,000 slightly different proteins which is 159 00:06:35,990 --> 00:06:34,560 what we call protein ice forms 160 00:06:38,790 --> 00:06:36,000 as you can see 161 00:06:42,230 --> 00:06:38,800 protein ice forms share some 162 00:06:43,749 --> 00:06:42,240 parts of the gene both differ norms 163 00:06:45,189 --> 00:06:43,759 and 164 00:06:49,350 --> 00:06:45,199 finally 165 00:06:52,870 --> 00:06:49,360 the concept of homologous characters 166 00:06:55,990 --> 00:06:52,880 at structural and molecular level 167 00:06:58,150 --> 00:06:56,000 when we look at a phylogenetic tree 168 00:06:59,749 --> 00:06:58,160 we have a series of 169 00:07:00,830 --> 00:06:59,759 characters 170 00:07:06,870 --> 00:07:00,840 and 171 00:07:11,830 --> 00:07:09,990 these characters need to be uh 172 00:07:14,309 --> 00:07:11,840 evolutionarily related in order to be 173 00:07:16,710 --> 00:07:14,319 placed in a phylogenetic tree but many 174 00:07:18,870 --> 00:07:16,720 times the these 175 00:07:19,990 --> 00:07:18,880 evolutionary relationships are not so 176 00:07:21,270 --> 00:07:20,000 obvious 177 00:07:24,150 --> 00:07:21,280 for example 178 00:07:27,270 --> 00:07:24,160 we take the fin of a whale the arm of a 179 00:07:28,830 --> 00:07:27,280 human being the leg of a lizard and the 180 00:07:31,749 --> 00:07:28,840 wing of a 181 00:07:33,909 --> 00:07:31,759 bird at first we may think that 182 00:07:36,469 --> 00:07:33,919 there is no relationship between them 183 00:07:38,950 --> 00:07:36,479 but when we look at the bones 184 00:07:41,350 --> 00:07:38,960 each of these structures we are going to 185 00:07:43,830 --> 00:07:41,360 see that they are exactly the same bones 186 00:07:45,830 --> 00:07:43,840 but they have suffered different 187 00:07:47,189 --> 00:07:45,840 modifications 188 00:07:49,110 --> 00:07:47,199 so 189 00:07:51,510 --> 00:07:49,120 these all of these 190 00:07:53,350 --> 00:07:51,520 characters are said to be homologous 191 00:07:56,710 --> 00:07:53,360 because 192 00:07:58,950 --> 00:07:56,720 they come from a single common ancestor 193 00:08:00,629 --> 00:07:58,960 and this also happens at the molecular 194 00:08:03,909 --> 00:08:00,639 level 195 00:08:09,029 --> 00:08:06,390 we have two kinds of 196 00:08:11,909 --> 00:08:09,039 homologous genes 197 00:08:15,029 --> 00:08:11,919 the first one is ortollo blue genes this 198 00:08:17,270 --> 00:08:15,039 is the same protein in 199 00:08:18,790 --> 00:08:17,280 in different organisms you take for 200 00:08:21,350 --> 00:08:18,800 example the 201 00:08:23,270 --> 00:08:21,360 the monologuing gene from the frog the 202 00:08:25,830 --> 00:08:23,280 human and the mouse 203 00:08:26,950 --> 00:08:25,840 it is the same gene but is present in 204 00:08:29,589 --> 00:08:26,960 different 205 00:08:31,510 --> 00:08:29,599 organs so this is what we call 206 00:08:32,870 --> 00:08:31,520 orthologues or 207 00:08:34,070 --> 00:08:32,880 ortolos 208 00:08:36,550 --> 00:08:34,080 and 209 00:08:38,310 --> 00:08:36,560 we also can have within the same 210 00:08:41,029 --> 00:08:38,320 organism 211 00:08:43,750 --> 00:08:41,039 different genes that are evolutionarily 212 00:08:47,190 --> 00:08:43,760 related like the 213 00:08:49,910 --> 00:08:47,200 alpha chain of the hemoglobin from mouse 214 00:08:53,590 --> 00:08:49,920 and also the beta chain and 215 00:08:54,389 --> 00:08:53,600 another protein called myoglobu 216 00:08:57,110 --> 00:08:54,399 so 217 00:08:59,350 --> 00:08:57,120 these are present in the same organism 218 00:09:03,509 --> 00:08:59,360 and are evolutionarily related this is 219 00:09:03,519 --> 00:09:06,630 well 220 00:09:11,030 --> 00:09:09,910 so what's what about the tnrc 221 00:09:13,670 --> 00:09:11,040 engine 222 00:09:15,750 --> 00:09:13,680 as we said this is the gene that 223 00:09:17,300 --> 00:09:15,760 uh what they tell proposed in their 224 00:09:18,389 --> 00:09:17,310 studio to be 225 00:09:20,790 --> 00:09:18,399 [Music] 226 00:09:22,550 --> 00:09:20,800 that it could be involved in 227 00:09:24,550 --> 00:09:22,560 psychic function 228 00:09:26,389 --> 00:09:24,560 this gene encodes a massive protein 229 00:09:28,470 --> 00:09:26,399 which is 10 times 230 00:09:31,509 --> 00:09:28,480 the size of the average protein 231 00:09:35,269 --> 00:09:31,519 the average protein is around 300 amino 232 00:09:37,590 --> 00:09:35,279 acids this protein is around 3 000 amino 233 00:09:40,550 --> 00:09:37,600 acids its function and structure have 234 00:09:42,070 --> 00:09:40,560 not been properly elucidated yet 235 00:09:44,230 --> 00:09:42,080 and 236 00:09:45,269 --> 00:09:44,240 but it's known that it expresses in many 237 00:09:47,190 --> 00:09:45,279 organs 238 00:09:48,550 --> 00:09:47,200 throughout the body and in different 239 00:09:52,310 --> 00:09:48,560 brain regions 240 00:09:53,590 --> 00:09:52,320 and this gene has nine isoforms which is 241 00:09:56,870 --> 00:09:53,600 also 242 00:09:57,910 --> 00:09:56,880 far above the avarage of 243 00:10:00,070 --> 00:09:57,920 most of 244 00:10:07,430 --> 00:10:00,080 human proteins which have 245 00:10:10,310 --> 00:10:09,030 well 246 00:10:12,150 --> 00:10:10,320 as i said 247 00:10:15,110 --> 00:10:12,160 this gene expresses 248 00:10:18,150 --> 00:10:15,120 different brain structures specifically 249 00:10:21,509 --> 00:10:18,160 in the cerebral cortex the hypocampus 250 00:10:22,389 --> 00:10:21,519 the caudate nucleus and the cerebellum 251 00:10:24,710 --> 00:10:22,399 and 252 00:10:26,870 --> 00:10:24,720 it has different levels of expressions 253 00:10:29,430 --> 00:10:26,880 depending on the 254 00:10:33,750 --> 00:10:29,440 the cell type of each of these 255 00:10:36,630 --> 00:10:35,350 and 256 00:10:37,750 --> 00:10:36,640 what i 257 00:10:42,470 --> 00:10:37,760 did here 258 00:10:46,150 --> 00:10:42,480 was a series of bioinformatics analysis 259 00:10:49,350 --> 00:10:46,160 i initially took the sequence of the dnr 260 00:10:50,310 --> 00:10:49,360 c18 gene from human 261 00:10:51,670 --> 00:10:50,320 and 262 00:10:53,030 --> 00:10:51,680 launch it 263 00:10:55,190 --> 00:10:53,040 to a 264 00:10:57,670 --> 00:10:55,200 specific database of completely 265 00:10:59,590 --> 00:10:57,680 sequenced genomes 266 00:11:02,710 --> 00:10:59,600 in order to look for 267 00:11:05,110 --> 00:11:02,720 homologous or evolutionarily related 268 00:11:11,030 --> 00:11:07,990 then i perform a series of structural 269 00:11:15,509 --> 00:11:13,350 specifically the prediction of the 270 00:11:16,630 --> 00:11:15,519 secondary structure of a protein which 271 00:11:19,030 --> 00:11:16,640 is the 272 00:11:21,110 --> 00:11:19,040 specific conformations that 273 00:11:22,550 --> 00:11:21,120 some parts of the proteins 274 00:11:24,790 --> 00:11:22,560 adopt 275 00:11:27,269 --> 00:11:24,800 i also 276 00:11:30,150 --> 00:11:27,279 did an empirical modeling of possible 277 00:11:31,509 --> 00:11:30,160 protein domains a protein domain 278 00:11:33,269 --> 00:11:31,519 is a 279 00:11:34,389 --> 00:11:33,279 protein region that 280 00:11:35,430 --> 00:11:34,399 has a 281 00:11:37,829 --> 00:11:35,440 specific 282 00:11:41,110 --> 00:11:37,839 structure and function 283 00:11:43,190 --> 00:11:41,120 this function can be catalytic but also 284 00:11:44,550 --> 00:11:43,200 regulatory 285 00:11:46,310 --> 00:11:44,560 or strong 286 00:11:48,389 --> 00:11:46,320 and 287 00:11:50,629 --> 00:11:48,399 well i also predicted 288 00:11:52,790 --> 00:11:50,639 the composition in terms of disordered 289 00:11:57,030 --> 00:11:52,800 radiance this in contrast with the 290 00:11:59,750 --> 00:11:57,040 protein domains are radians that as its 291 00:12:02,470 --> 00:11:59,760 name says is our disorder they do not 292 00:12:04,790 --> 00:12:02,480 adopt a specific structure 293 00:12:07,590 --> 00:12:04,800 and finally i perform a series of 294 00:12:08,470 --> 00:12:07,600 sequence alignments 295 00:12:11,990 --> 00:12:08,480 with 296 00:12:15,190 --> 00:12:12,000 some of the domains that i identified 297 00:12:17,030 --> 00:12:15,200 in order to see if they were present in 298 00:12:19,750 --> 00:12:17,040 this program 299 00:12:21,590 --> 00:12:19,760 in the tnr c18 300 00:12:24,870 --> 00:12:21,600 well 301 00:12:27,509 --> 00:12:24,880 the first part of the results concerning 302 00:12:31,750 --> 00:12:27,519 the distribution of the 303 00:12:33,350 --> 00:12:31,760 sequences found in this database 304 00:12:35,350 --> 00:12:33,360 these are the 305 00:12:38,389 --> 00:12:35,360 this is the distribution of the 306 00:12:39,190 --> 00:12:38,399 dnrc8 potential homologs and 307 00:12:48,870 --> 00:12:39,200 i 308 00:12:53,670 --> 00:12:48,880 mostly an exploratory search 309 00:12:56,629 --> 00:12:53,680 so far it is not possible to discern if 310 00:12:59,030 --> 00:12:56,639 all of the sequence that i found are 311 00:13:00,069 --> 00:12:59,040 really evolutionarily related 312 00:13:03,509 --> 00:13:00,079 or 313 00:13:05,750 --> 00:13:03,519 they are similar to the tnr18 protein 314 00:13:09,110 --> 00:13:05,760 because of chance this is 315 00:13:11,509 --> 00:13:09,120 something that happens a lot in 316 00:13:13,190 --> 00:13:11,519 when someone 317 00:13:15,590 --> 00:13:13,200 searches a 318 00:13:17,509 --> 00:13:15,600 specific gene sequence against a very 319 00:13:18,310 --> 00:13:17,519 large database 320 00:13:20,470 --> 00:13:18,320 so 321 00:13:22,710 --> 00:13:20,480 in this case 322 00:13:27,990 --> 00:13:25,190 proteins that are similar and 323 00:13:30,069 --> 00:13:28,000 are mainly found in animals 324 00:13:31,670 --> 00:13:30,079 which is the 325 00:13:34,389 --> 00:13:31,680 thing is like 326 00:13:38,230 --> 00:13:34,399 some kind of orange color here 327 00:13:41,110 --> 00:13:38,240 and also in plants which is 328 00:13:42,069 --> 00:13:41,120 this great slice 329 00:13:45,829 --> 00:13:42,079 and 330 00:13:50,470 --> 00:13:45,839 i found a very few heats in 331 00:13:54,790 --> 00:13:50,480 fungi in protists and in prokaryotes 332 00:13:59,509 --> 00:13:58,710 so within animals i found that most of 333 00:14:03,030 --> 00:13:59,519 the 334 00:14:05,189 --> 00:14:03,040 chordates 335 00:14:06,470 --> 00:14:05,199 which is the group to which 336 00:14:08,550 --> 00:14:06,480 we belong as 337 00:14:09,509 --> 00:14:08,560 human beings 338 00:14:12,150 --> 00:14:09,519 and 339 00:14:14,310 --> 00:14:12,160 also a vast number of new 340 00:14:15,509 --> 00:14:14,320 arthropods and to a lesser degree in 341 00:14:16,710 --> 00:14:15,519 moles 342 00:14:18,870 --> 00:14:16,720 worms 343 00:14:21,030 --> 00:14:18,880 sea urchins and 344 00:14:23,030 --> 00:14:21,040 jellyfish 345 00:14:24,629 --> 00:14:23,040 and this is the 346 00:14:27,030 --> 00:14:24,639 interesting part 347 00:14:33,750 --> 00:14:30,710 these are not potential homologs but 348 00:14:35,590 --> 00:14:33,760 the dnrc18 gene 349 00:14:39,430 --> 00:14:35,600 but 350 00:14:41,509 --> 00:14:39,440 found in many other organisms other than 351 00:14:43,269 --> 00:14:41,519 humans 352 00:14:46,310 --> 00:14:43,279 as you can see 353 00:14:49,829 --> 00:14:46,320 it is mainly found in mammals 354 00:14:52,710 --> 00:14:49,839 but also in almost all main vertebrae 355 00:14:55,430 --> 00:14:52,720 groups like fish 356 00:14:56,829 --> 00:14:55,440 reptiles which are divided into 357 00:15:01,750 --> 00:14:56,839 crocodiles and 358 00:15:06,629 --> 00:15:04,550 and we also found it in 359 00:15:10,710 --> 00:15:06,639 some art roblox 360 00:15:13,509 --> 00:15:10,720 and in one flat one the only 361 00:15:16,710 --> 00:15:13,519 vertebrate rooting which i did not found 362 00:15:18,710 --> 00:15:16,720 any kids for this protein 363 00:15:19,590 --> 00:15:18,720 was the amphibians 364 00:15:22,069 --> 00:15:19,600 but 365 00:15:24,949 --> 00:15:22,079 this not necessarily means that 366 00:15:26,949 --> 00:15:24,959 it is not present in amphibians it could 367 00:15:27,670 --> 00:15:26,959 also mean that 368 00:15:31,749 --> 00:15:27,680 the 369 00:15:34,870 --> 00:15:31,759 sequence of this gene has diverged 370 00:15:36,629 --> 00:15:34,880 at a very fast rate and 371 00:15:39,110 --> 00:15:36,639 it is no longer 372 00:15:42,550 --> 00:15:39,120 identified through simple searches like 373 00:15:45,910 --> 00:15:42,560 this we will need to perform uh most 374 00:15:47,030 --> 00:15:45,920 robust searches and analysis if we want 375 00:15:49,990 --> 00:15:47,040 to 376 00:15:55,590 --> 00:15:50,000 identify if this gene is really absent 377 00:15:58,389 --> 00:15:56,629 so 378 00:16:00,710 --> 00:15:58,399 what about the functions 379 00:16:03,590 --> 00:16:00,720 associated with all of the sequences 380 00:16:07,350 --> 00:16:06,470 here is the number of hits that 381 00:16:10,870 --> 00:16:07,360 are 382 00:16:14,310 --> 00:16:10,880 annotated with a specific function 383 00:16:18,470 --> 00:16:17,350 the most common function is this the bah 384 00:16:19,560 --> 00:16:18,480 which 385 00:16:21,509 --> 00:16:19,570 stands for the 386 00:16:23,350 --> 00:16:21,519 [Music] 387 00:16:25,430 --> 00:16:23,360 this is the name of the a specific 388 00:16:28,550 --> 00:16:25,440 domain 389 00:16:30,310 --> 00:16:28,560 and it is found mainly in plants 390 00:16:34,470 --> 00:16:30,320 uh but also 391 00:16:39,590 --> 00:16:37,189 this 392 00:16:43,350 --> 00:16:39,600 protein domain is involved in the 393 00:16:48,470 --> 00:16:45,829 we also found the 394 00:16:51,269 --> 00:16:48,480 the specific tnrc18 395 00:16:52,870 --> 00:16:51,279 function which corresponds to the 396 00:16:55,110 --> 00:16:52,880 previous slide 397 00:16:56,790 --> 00:16:55,120 to this run 398 00:16:58,069 --> 00:16:56,800 all of these 399 00:16:59,509 --> 00:16:58,079 hits are 400 00:17:01,189 --> 00:16:59,519 grouped into 401 00:17:02,069 --> 00:17:01,199 this function 402 00:17:05,429 --> 00:17:02,079 and 403 00:17:07,750 --> 00:17:05,439 we find also 404 00:17:10,949 --> 00:17:07,760 some proteins that are 405 00:17:14,390 --> 00:17:10,959 involved in chromatin remodeling 406 00:17:15,990 --> 00:17:14,400 and others like the winged dye 407 00:17:20,789 --> 00:17:16,000 it's a 408 00:17:22,230 --> 00:17:20,799 protein typical of arthropods and if 409 00:17:25,270 --> 00:17:22,240 the term 410 00:17:27,270 --> 00:17:25,280 times the 411 00:17:29,990 --> 00:17:27,280 the specific position of 412 00:17:33,669 --> 00:17:30,000 several parts of the body and 413 00:17:35,270 --> 00:17:33,679 finally to a much lesser degree the phd 414 00:17:40,470 --> 00:17:35,280 function 415 00:17:45,750 --> 00:17:43,909 so regarding the structural analysis of 416 00:17:47,830 --> 00:17:45,760 this zoom 417 00:17:50,630 --> 00:17:47,840 is the 418 00:17:53,750 --> 00:17:50,640 distribution of disordered radiance this 419 00:17:59,510 --> 00:17:55,430 these are 420 00:18:02,870 --> 00:17:59,520 defined everything that is above this 421 00:18:04,630 --> 00:18:02,880 line is considered to be a disordered 422 00:18:06,470 --> 00:18:04,640 region 423 00:18:08,390 --> 00:18:06,480 but this below is 424 00:18:11,909 --> 00:18:08,400 likely to be uh 425 00:18:14,789 --> 00:18:11,919 a protein domain so 426 00:18:17,830 --> 00:18:14,799 what is reported in the many databases 427 00:18:19,270 --> 00:18:17,840 is this domain the bih which as you can 428 00:18:21,430 --> 00:18:19,280 see 429 00:18:24,310 --> 00:18:21,440 corresponds to only a small portion of 430 00:18:27,270 --> 00:18:24,320 the protons about a tenth of the protein 431 00:18:29,350 --> 00:18:27,280 and the the hypothetical function of 432 00:18:33,029 --> 00:18:29,360 this protein is 433 00:18:35,590 --> 00:18:33,039 predicted based on this specific 434 00:18:40,070 --> 00:18:35,600 but i 435 00:18:48,390 --> 00:18:43,590 the genes that 436 00:18:52,390 --> 00:18:49,750 responding to the functions that i 437 00:18:54,310 --> 00:18:52,400 showed you in the previous slide and 438 00:18:57,029 --> 00:18:54,320 i found that 439 00:18:58,549 --> 00:18:57,039 another domain called the tutor domain 440 00:19:01,270 --> 00:18:58,559 is also 441 00:19:03,430 --> 00:19:01,280 it aligns 442 00:19:07,270 --> 00:19:03,440 very well with this 443 00:19:08,630 --> 00:19:07,280 other region of the tnrc18 protein 444 00:19:10,470 --> 00:19:08,640 and 445 00:19:13,350 --> 00:19:10,480 this this is 446 00:19:14,630 --> 00:19:13,360 has been reported in the territory but 447 00:19:17,350 --> 00:19:14,640 only in 448 00:19:19,750 --> 00:19:17,360 two or three cases but 449 00:19:22,310 --> 00:19:19,760 the novelty here is this other domain 450 00:19:24,950 --> 00:19:22,320 the hoax 9 domain 451 00:19:27,590 --> 00:19:24,960 this has not been previously reported to 452 00:19:31,029 --> 00:19:27,600 be part of this protein but 453 00:19:33,430 --> 00:19:31,039 when i aligned the sequence of 454 00:19:36,710 --> 00:19:33,440 protein with half this domain 455 00:19:39,350 --> 00:19:36,720 with the dnrc8 protein 456 00:19:42,310 --> 00:19:39,360 there is a high similarity 457 00:19:43,990 --> 00:19:42,320 between both of them and it 458 00:19:45,350 --> 00:19:44,000 aligns exactly 459 00:19:46,630 --> 00:19:45,360 this region 460 00:19:49,029 --> 00:19:46,640 which 461 00:19:51,590 --> 00:19:49,039 the algorithm predicts to be and 462 00:19:52,470 --> 00:19:51,600 non-disordered version 463 00:19:53,830 --> 00:19:52,480 so 464 00:19:56,150 --> 00:19:53,840 at least 465 00:20:00,549 --> 00:19:56,160 we have three different protein domains 466 00:20:07,190 --> 00:20:03,110 all of these domains the va 467 00:20:12,149 --> 00:20:07,200 h the two layer holds b9 are somehow 468 00:20:14,630 --> 00:20:13,590 so 469 00:20:18,470 --> 00:20:14,640 this 470 00:20:20,630 --> 00:20:18,480 suggests us that the tnr18 protein 471 00:20:22,310 --> 00:20:20,640 could be part of a transcriptional 472 00:20:23,830 --> 00:20:22,320 regulation network 473 00:20:26,310 --> 00:20:23,840 and those 474 00:20:33,270 --> 00:20:26,320 might not be the only one responsible 475 00:20:37,590 --> 00:20:36,710 there is evidence uh 476 00:20:39,270 --> 00:20:37,600 other 477 00:20:41,530 --> 00:20:39,280 brain aspects 478 00:20:42,870 --> 00:20:41,540 that are dependent on 479 00:20:45,190 --> 00:20:42,880 [Music] 480 00:20:47,909 --> 00:20:45,200 this kind of 481 00:20:51,110 --> 00:20:47,919 networks for example some aspects of 482 00:20:54,630 --> 00:20:53,990 some brain disorders 483 00:20:55,990 --> 00:20:54,640 in which 484 00:20:57,430 --> 00:20:56,000 [Music] 485 00:21:00,470 --> 00:20:57,440 a brain a 486 00:21:04,470 --> 00:21:00,480 transcriptional regulation network is 487 00:21:08,870 --> 00:21:06,950 so you may wonder if 488 00:21:10,390 --> 00:21:08,880 how could a 489 00:21:15,029 --> 00:21:10,400 single 490 00:21:16,630 --> 00:21:15,039 sleep could make all the difference in 491 00:21:19,909 --> 00:21:16,640 this case well 492 00:21:23,190 --> 00:21:19,919 so far we do not know 493 00:21:25,430 --> 00:21:23,200 the results that reported 494 00:21:25,440 --> 00:21:30,230 very preliminary 495 00:21:36,070 --> 00:21:34,230 they report a aberration in a single 496 00:21:38,950 --> 00:21:36,080 position of 497 00:21:40,870 --> 00:21:38,960 a non-coding region of this gene 498 00:21:43,029 --> 00:21:40,880 but 499 00:21:46,470 --> 00:21:43,039 in the literature it has been reported 500 00:21:49,270 --> 00:21:46,480 that in other genes 501 00:21:51,350 --> 00:21:49,280 when we have a variation in 502 00:21:53,350 --> 00:21:51,360 unique slip we think 503 00:21:55,590 --> 00:21:53,360 also the infrared gradients or the 504 00:21:58,149 --> 00:21:55,600 non-coding gradients of the gene 505 00:22:00,870 --> 00:21:58,159 well this can result in the expression 506 00:22:03,909 --> 00:22:00,880 of different protein ice forms 507 00:22:05,270 --> 00:22:03,919 so a possibility is that 508 00:22:07,990 --> 00:22:05,280 people that 509 00:22:09,430 --> 00:22:08,000 have the let's call it the psychic 510 00:22:10,549 --> 00:22:09,440 variant 511 00:22:12,630 --> 00:22:10,559 express 512 00:22:13,789 --> 00:22:12,640 some protein isoform 513 00:22:17,510 --> 00:22:13,799 and a 514 00:22:20,549 --> 00:22:17,520 non-sticky people express 515 00:22:22,470 --> 00:22:20,559 another isotope of the same 516 00:22:25,350 --> 00:22:22,480 protein 517 00:22:27,669 --> 00:22:25,360 and just to show you the importance of a 518 00:22:28,549 --> 00:22:27,679 single nucleotide change in a gene 519 00:22:30,149 --> 00:22:28,559 and 520 00:22:37,830 --> 00:22:30,159 i 521 00:22:41,350 --> 00:22:37,840 normal red blood cells and 522 00:22:45,510 --> 00:22:41,360 secant cell anemia 523 00:22:53,830 --> 00:22:47,110 as 524 00:22:55,270 --> 00:22:53,840 that affects 525 00:22:59,669 --> 00:22:55,280 large part of 526 00:23:03,029 --> 00:22:59,679 the population specifically in africa 527 00:23:07,590 --> 00:23:05,830 the only difference between 528 00:23:10,470 --> 00:23:07,600 this kind of cells and 529 00:23:17,350 --> 00:23:12,230 other 530 00:23:20,310 --> 00:23:17,360 is a mutation in a single nucleotide 531 00:23:21,669 --> 00:23:20,320 not within the known sequence but in the 532 00:23:25,350 --> 00:23:21,679 coding sequence 533 00:23:26,870 --> 00:23:25,360 so this results in a change of a single 534 00:23:29,270 --> 00:23:26,880 amino acid 535 00:23:31,270 --> 00:23:29,280 in this case volume instead of glutamic 536 00:23:31,990 --> 00:23:31,280 acid and 537 00:23:34,070 --> 00:23:32,000 the 538 00:23:36,710 --> 00:23:34,080 molecule in chains are 539 00:23:39,750 --> 00:23:36,720 have an altered confirmation 540 00:23:42,149 --> 00:23:39,760 and ultimately this results in 541 00:23:43,750 --> 00:23:42,159 the production of abnormal 542 00:23:44,710 --> 00:23:43,760 red blood cells 543 00:23:47,510 --> 00:23:44,720 so 544 00:23:51,190 --> 00:23:49,669 yeah a single 545 00:23:53,110 --> 00:23:51,200 change in 546 00:23:55,430 --> 00:23:53,120 a single neuropathy 547 00:23:59,269 --> 00:23:55,440 can have very dramatic 548 00:23:59,279 --> 00:24:03,269 so what can be completed here 549 00:24:07,350 --> 00:24:05,269 the first thing is that the molecular 550 00:24:10,630 --> 00:24:07,360 basis for psychic abilities are more 551 00:24:13,350 --> 00:24:10,640 likely to rely on a protein network than 552 00:24:17,430 --> 00:24:13,360 on a single gene or a single 553 00:24:24,149 --> 00:24:21,590 perhaps even the functions identified 554 00:24:27,430 --> 00:24:24,159 for three of the domains that are likely 555 00:24:29,510 --> 00:24:27,440 to be present in the dnrc8 protein 556 00:24:32,149 --> 00:24:29,520 this network is a transcriptional 557 00:24:36,950 --> 00:24:32,159 regulation one 558 00:24:39,430 --> 00:24:36,960 and if the human pnrc18 gene is 559 00:24:41,110 --> 00:24:39,440 somehow associated with 560 00:24:41,990 --> 00:24:41,120 side 561 00:24:44,230 --> 00:24:42,000 it is 562 00:24:46,549 --> 00:24:44,240 likely that this is also the case in 563 00:24:51,430 --> 00:24:46,559 different organisms in which 564 00:24:58,830 --> 00:24:54,789 as you can remember the tnrc 18 gene is 565 00:25:01,269 --> 00:24:58,840 found in all main vertebrates all about 566 00:25:01,800 --> 00:25:01,279 confidence and 567 00:25:04,230 --> 00:25:01,810 we can 568 00:25:06,070 --> 00:25:04,240 [Music] 569 00:25:08,310 --> 00:25:06,080 if we 570 00:25:09,190 --> 00:25:08,320 turn to the evidence 571 00:25:12,789 --> 00:25:09,200 from 572 00:25:18,230 --> 00:25:15,029 we find that 573 00:25:21,909 --> 00:25:19,669 animals 574 00:25:24,710 --> 00:25:21,919 in which 575 00:25:26,390 --> 00:25:24,720 you suggested that they have some level 576 00:25:29,029 --> 00:25:26,400 of side 577 00:25:30,789 --> 00:25:29,039 yeah 578 00:25:33,750 --> 00:25:30,799 and uh 579 00:25:38,310 --> 00:25:36,390 just to elaborate a little bit more into 580 00:25:43,029 --> 00:25:38,320 this 581 00:25:46,070 --> 00:25:43,039 tree 582 00:25:49,510 --> 00:25:46,080 relax the amphibians because 583 00:25:54,390 --> 00:25:49,520 we did not find the tnrc 18g 584 00:26:01,029 --> 00:25:57,590 what we do have is this 585 00:26:04,230 --> 00:26:01,039 the presence of the tnrc18 protein in 586 00:26:06,870 --> 00:26:04,240 fish birds non-human mammals and 587 00:26:11,909 --> 00:26:08,950 according to the principles of 588 00:26:16,950 --> 00:26:11,919 evolutionary biology 589 00:26:21,269 --> 00:26:19,430 we can use the principle of maximum 590 00:26:22,390 --> 00:26:21,279 parsimony 591 00:26:23,590 --> 00:26:22,400 and 592 00:26:24,470 --> 00:26:23,600 say well 593 00:26:26,549 --> 00:26:24,480 these 594 00:26:27,590 --> 00:26:26,559 three seems 595 00:26:29,669 --> 00:26:27,600 to be 596 00:26:32,470 --> 00:26:29,679 complicated because 597 00:26:34,789 --> 00:26:32,480 it would mean that this gene appeared 598 00:26:37,350 --> 00:26:34,799 independently 599 00:26:41,590 --> 00:26:37,360 within each of these 600 00:26:44,310 --> 00:26:43,190 each of them 601 00:26:45,990 --> 00:26:44,320 each of these 602 00:26:47,750 --> 00:26:46,000 characters is 603 00:26:49,350 --> 00:26:47,760 considered 604 00:26:50,870 --> 00:26:49,360 is called a step 605 00:26:53,510 --> 00:26:50,880 and 606 00:26:55,750 --> 00:26:53,520 this means that this specific phylogeny 607 00:26:59,430 --> 00:26:55,760 isotopical phylogenetic three has four 608 00:27:01,990 --> 00:26:59,440 steps but there is a most parsimonious 609 00:27:03,990 --> 00:27:02,000 explanation 610 00:27:06,710 --> 00:27:04,000 which is this 611 00:27:07,990 --> 00:27:06,720 this means that tnrc18 612 00:27:09,590 --> 00:27:08,000 gene 613 00:27:10,710 --> 00:27:09,600 originated 614 00:27:12,870 --> 00:27:10,720 at a time 615 00:27:14,390 --> 00:27:12,880 before the divergence of 616 00:27:15,430 --> 00:27:14,400 all of these groups 617 00:27:18,549 --> 00:27:15,440 and 618 00:27:20,630 --> 00:27:18,559 well when they diverge they already have 619 00:27:22,389 --> 00:27:20,640 this specific gene 620 00:27:24,870 --> 00:27:22,399 this tree is 621 00:27:26,549 --> 00:27:24,880 less complicated it involves only one 622 00:27:28,310 --> 00:27:26,559 step 623 00:27:30,710 --> 00:27:28,320 and 624 00:27:33,510 --> 00:27:30,720 it has been shown in 625 00:27:36,470 --> 00:27:33,520 many cases that 626 00:27:37,590 --> 00:27:36,480 we have two hypotheses the left one and 627 00:27:39,110 --> 00:27:37,600 the right one 628 00:27:40,549 --> 00:27:39,120 there 629 00:27:43,750 --> 00:27:40,559 most likely 630 00:27:45,510 --> 00:27:43,760 is this one 631 00:27:48,950 --> 00:27:45,520 the one with the 632 00:27:52,950 --> 00:27:48,960 less number of steps and 633 00:27:54,470 --> 00:27:52,960 these perhaps could also apply to the 634 00:27:56,549 --> 00:27:54,480 site 635 00:27:58,630 --> 00:27:56,559 if we review the 636 00:28:00,230 --> 00:27:58,640 all of the experiments 637 00:28:03,669 --> 00:28:00,240 done in the field of 638 00:28:10,470 --> 00:28:08,630 it has been suggested in fish birds in 639 00:28:13,430 --> 00:28:10,480 non-human mammals and 640 00:28:14,830 --> 00:28:13,440 obviously in humans 641 00:28:17,029 --> 00:28:14,840 so it is a 642 00:28:18,549 --> 00:28:17,039 pattern pretty much like 643 00:28:23,029 --> 00:28:18,559 the one of the 644 00:28:25,669 --> 00:28:23,039 distribution of the tnrc8 engine and 645 00:28:27,110 --> 00:28:25,679 perhaps a simpler hypothesis would be 646 00:28:28,470 --> 00:28:27,120 this that 647 00:28:31,190 --> 00:28:28,480 psy did not 648 00:28:33,669 --> 00:28:31,200 originated independently in 649 00:28:37,110 --> 00:28:33,679 each of these groups but 650 00:28:40,870 --> 00:28:37,120 originated at least before the 651 00:28:43,830 --> 00:28:40,880 divergence of vertebrates 652 00:28:46,470 --> 00:28:43,840 it could also be have 653 00:28:47,669 --> 00:28:46,480 could also have originated even before 654 00:28:49,990 --> 00:28:47,679 but uh 655 00:28:52,389 --> 00:28:50,000 with the evidence so far this is the 656 00:28:54,310 --> 00:28:52,399 farthest we can go 657 00:28:56,630 --> 00:28:54,320 and finally the 658 00:28:58,870 --> 00:28:56,640 which are the perspectives 659 00:29:00,389 --> 00:28:58,880 for the well 660 00:29:02,789 --> 00:29:00,399 obviously further 661 00:29:04,710 --> 00:29:02,799 phylogenetic analysis with distantly 662 00:29:05,510 --> 00:29:04,720 related molecules 663 00:29:07,510 --> 00:29:05,520 which 664 00:29:11,510 --> 00:29:07,520 could help us to elucidate the 665 00:29:12,549 --> 00:29:11,520 evolutionary history of the dnrc8 engine 666 00:29:14,950 --> 00:29:12,559 and 667 00:29:17,190 --> 00:29:14,960 if we combine these with more robust 668 00:29:20,630 --> 00:29:17,200 genetic studies that follow the line of 669 00:29:26,310 --> 00:29:23,190 this could give us a wider picture of a 670 00:29:27,190 --> 00:29:26,320 molecular basis of sight in functioning 671 00:29:29,830 --> 00:29:27,200 and 672 00:29:31,830 --> 00:29:29,840 we could make use of for example the 673 00:29:35,669 --> 00:29:31,840 microarray technologies 674 00:29:36,630 --> 00:29:35,679 transcriptomics and proteomics and also 675 00:29:40,460 --> 00:29:36,640 a 676

00:29:51,590 have 681 00:29:57,269 --> 00:29:54,399 a specific anomaly of in a particular 682 00:29:59,110 --> 00:29:57,279 brain structure that is lacking in 683 00:29:59,909 --> 00:29:59,120 people that are 684 00:30:02,149 --> 00:29:59,919 have 685 00:30:03,029 --> 00:30:02,159 a non-sized bearing 686 00:30:05,269 --> 00:30:03,039 and 687 00:30:06,950 --> 00:30:05,279 well that's pretty much it thank you 688 00:30:08,630 --> 00:30:06,960 very much 689 00:30:11,669 --> 00:30:08,640 thank you alex 690 00:30:13,350 --> 00:30:11,679 we do have one question 691 00:30:15,750 --> 00:30:13,360 first i see actually two questions now 692 00:30:17,430 --> 00:30:15,760 so one question is does this imply 693 00:30:19,269 --> 00:30:17,440 that psi potential may have been 694 00:30:22,789 --> 00:30:19,279 developed before fish in the 695 00:30:25,110 --> 00:30:22,799 evolutionary time frame 696 00:30:27,430 --> 00:30:25,120 yeah yeah it is 697 00:30:30,230 --> 00:30:27,440 a hypothesis uh 698 00:30:31,990 --> 00:30:30,240 as i showed you in the 699 00:30:34,830 --> 00:30:32,000 this hypothetical 700 00:30:36,630 --> 00:30:34,840 phylogenetic tree 701 00:30:39,510 --> 00:30:36,640 fish 702 00:30:41,110 --> 00:30:39,520 there have been several studies with 703 00:30:42,470 --> 00:30:41,120 fish which 704 00:30:44,389 --> 00:30:42,480 suggested that 705 00:30:47,190 --> 00:30:44,399 they do have 706 00:30:48,470 --> 00:30:47,200 some levels of site 707 00:30:50,149 --> 00:30:48,480 so 708 00:30:52,070 --> 00:30:50,159 if we uh 709 00:30:53,520 --> 00:30:52,080 but well not only fish 710 00:30:54,870 --> 00:30:53,530 also reptiles and 711 00:30:56,470 --> 00:30:54,880 [Music] 712 00:31:04,470 --> 00:30:56,480 i 713 00:31:06,310 --> 00:31:04,480 so 714 00:31:10,549 --> 00:31:06,320 this 715 00:31:14,789 --> 00:31:13,269 organisms belong to the same clad the 716 00:31:17,029 --> 00:31:14,799 vertebrates 717 00:31:23,990 --> 00:31:21,190 if fish have some level of sight 718 00:31:26,950 --> 00:31:24,000 the most likely explanation is that this 719 00:31:28,149 --> 00:31:26,960 trait appeared before the divergence of 720 00:31:31,029 --> 00:31:28,159 fish 721 00:31:33,110 --> 00:31:31,039 which would mean that 722 00:31:37,029 --> 00:31:33,120 even before the divergence of 723 00:31:39,029 --> 00:31:37,909 okay 724 00:31:41,110 --> 00:31:39,039 thank you 725 00:31:42,549 --> 00:31:41,120 another question are there other snps 726 00:31:44,149 --> 00:31:42,559 that were found that are found across 727 00:31:45,509 --> 00:31:44,159 the phylum genetic 728 00:31:47,269 --> 00:31:45,519 trees 729 00:31:48,070 --> 00:31:47,279 could you repeat the question please 730 00:31:50,789 --> 00:31:48,080 sure 731 00:31:54,070 --> 00:31:50,799 are there other snps that are found 732 00:31:55,269 --> 00:31:54,080 across the phylogenetic tree if so why 733 00:31:56,950 --> 00:31:55,279 would this be 734 00:32:00,310 --> 00:31:56,960 why would this one be involved in psy 735 00:32:03,830 --> 00:32:00,320 versus others 736 00:32:07,350 --> 00:32:06,070 i'm sorry i think i 737 00:32:08,630 --> 00:32:07,360 it's not 738 00:32:09,590 --> 00:32:08,640 [Music] 739 00:32:11,350 --> 00:32:09,600 other 740 00:32:13,430 --> 00:32:11,360 snips 741 00:32:15,830 --> 00:32:13,440 i assume it's i assume the question is 742 00:32:16,630 --> 00:32:15,840 related to snips 743 00:32:19,350 --> 00:32:16,640 well 744 00:32:21,350 --> 00:32:19,360 so far the only one that has been 745 00:32:24,230 --> 00:32:21,360 identified is 746 00:32:26,710 --> 00:32:24,240 this one the from the snip from this 747 00:32:28,350 --> 00:32:26,720 gene the dnrc 18 748 00:32:30,870 --> 00:32:28,360 gene 749 00:32:33,669 --> 00:32:30,880 [Music] 750 00:32:36,389 --> 00:32:35,430 something that can be done is 751 00:32:39,269 --> 00:32:36,399 take the 752 00:32:40,070 --> 00:32:39,279 the intronic sequence of which this snip 753 00:32:41,029 --> 00:32:40,080 is 754 00:32:44,470 --> 00:32:41,039 and 755 00:32:47,269 --> 00:32:44,480 compare it with the sequences of 756 00:32:49,669 --> 00:32:47,279 fish genes or reptile genes 757 00:32:55,590 --> 00:32:51,990 perform an alignment of all of these 758 00:32:57,909 --> 00:32:55,600 sequences and here you can find if 759 00:32:59,029 --> 00:32:57,919 this particular sniff is consistent 760 00:33:02,310 --> 00:32:59,039 across 761 00:33:05,190 --> 00:33:02,320 the vertebrates or on is only present in 762 00:33:06,470 --> 00:33:05,200 humans or in humans and some other group 763 00:33:08,389 --> 00:33:06,480 and 764 00:33:11,269 --> 00:33:08,399 you 765 00:33:13,269 --> 00:33:11,279 could also detect other 766 00:33:15,830 --> 00:33:13,279 particular snips 767 00:33:20,470 --> 00:33:18,470 i think it 768 00:33:23,029 --> 00:33:20,480 you could not say these 769 00:33:27,190 --> 00:33:23,039 snips are somehow 770 00:33:29,570 --> 00:33:28,630 you are not 771 00:33:31,029 --> 00:33:29,580 evaluating 772 00:33:32,710 --> 00:33:31,039 [Music] 773 00:33:43,110 --> 00:33:32,720 the presence of sight in this other 774 00:33:49,909 --> 00:33:46,870 other animals they have 775 00:33:53,190 --> 00:33:49,919 some level of psy and also 776 00:33:55,029 --> 00:33:53,200 their ancestors also had it and 777 00:33:59,509 --> 00:33:55,039 something quite similar to 778 00:34:04,230 --> 00:34:01,430 but at least for this specific variant 779 00:34:10,950 --> 00:34:07,350 you can find out it is present in 780 00:34:14,149 --> 00:34:11,990 okay 781 00:34:16,629 --> 00:34:14,159 so and i just want to thank ramses and 782 00:34:20,149 --> 00:34:16,639 analysis for posting a couple of links 783 00:34:23,510 --> 00:34:20,159 both to your abstract and also to uh the 784 00:34:25,510 -->

actually two related 821 00:36:19,910 --> 00:36:17,839 questions um 822 00:36:22,710 --> 00:36:19,920 how did you learn about hawaiian wabe's 823 00:36:24,069 --> 00:36:22,720 article and what inspired you 824 00:36:26,390 --> 00:36:24,079 oh 825 00:36:28,310 --> 00:36:26,400 yeah well 826 00:36:30,230 --> 00:36:28,320 uh i do not want 827 00:36:32,069 --> 00:36:30,240 to spoil you guys because this is 828 00:36:34,470 --> 00:36:32,079 something that i will mention 829 00:36:37,589 --> 00:36:34,480 my talk of tomorrow about uh 830 00:36:41,109 --> 00:36:37,599 did i learn about this 831 00:36:44,550 --> 00:36:41,119 i was interested in this because 832 00:36:47,190 --> 00:36:44,560 as an evolutionary biologist i 833 00:36:49,990 --> 00:36:47,200 this is something that i do i 834 00:36:52,150 --> 00:36:50,000 i'm not an experimental biologist not 835 00:36:55,430 --> 00:36:52,160 also a field biologist but i'm 836 00:36:56,870 --> 00:36:55,440 a informed information 837 00:36:58,870 --> 00:36:56,880 so it's 838 00:37:01,430 --> 00:36:58,880 in my master 839 00:37:02,630 --> 00:37:01,440 and my phd is 840 00:37:04,069 --> 00:37:02,640 what i'm used to 841 00:37:07,030 --> 00:37:04,079 so 842 00:37:10,390 --> 00:37:08,870 i uh 843 00:37:11,589 --> 00:37:10,400 around 844 00:37:14,630 --> 00:37:11,599 a year ago 845 00:37:17,510 --> 00:37:14,640 i think perhaps a year and a half in the 846 00:37:20,470 --> 00:37:17,520 website of the institute of sciences i 847 00:37:21,589 --> 00:37:20,480 found a pro this project the genetics of 848 00:37:22,950 --> 00:37:21,599 psychic 849 00:37:24,150 --> 00:37:22,960 abilities 850 00:37:27,510 --> 00:37:24,160 and 851 00:37:29,620 --> 00:37:27,520 i also found that a 852 00:37:31,030 --> 00:37:29,630 consultant on this project was a 853 00:37:32,390 --> 00:37:31,040 [Music] 854 00:37:35,589 --> 00:37:32,400 very famous 855 00:37:36,870 --> 00:37:35,599 geneticist dr gary nolan from stanford 856 00:37:39,910 --> 00:37:36,880 university 857 00:37:43,670 --> 00:37:39,920 and so i began to follow this 858 00:37:43,680 --> 00:37:45,990 well 859 00:37:51,589 --> 00:37:47,589 i think in 860 00:37:54,790 --> 00:37:51,599 the 2019 meeting within writing shows 861 00:37:58,310 --> 00:37:54,800 some preliminary results of this project 862 00:38:00,710 --> 00:37:59,349 when i 863 00:38:02,630 --> 00:38:00,720 read a 864 00:38:03,670 --> 00:38:02,640 paper 865 00:38:05,109 --> 00:38:03,680 what 866 00:38:08,950 --> 00:38:05,119 came to my mind 867 00:38:12,550 --> 00:38:10,870 but we have finally a 868 00:38:13,510 --> 00:38:12,560 gene which 869 00:38:15,829 --> 00:38:13,520 has 870 00:38:17,829 --> 00:38:15,839 with reported sequences a reported 871 00:38:20,150 --> 00:38:17,839 sequence 872 00:38:23,510 --> 00:38:20,160 can be analyzed through this kind of 873 00:38:23,520 --> 00:38:27,990 i decided to 874 00:38:30,710 --> 00:38:29,349 it would be a 875 00:38:32,790 --> 00:38:30,720 some 876 00:38:33,990 --> 00:38:32,800 kind of easy task 877 00:38:35,910 --> 00:38:34,000 so i 878 00:38:38,230 --> 00:38:35,920 took the this sequence from the 879 00:38:40,150 --> 00:38:38,240 [Music] 880 00:38:43,030 --> 00:38:40,160 that they reported and i began to 881 00:38:44,069 --> 00:38:43,040 perform different uh analysis 882 00:38:46,870 --> 00:38:44,079 and 883 00:38:49,109 --> 00:38:46,880 i finally came to what i will show you 884 00:38:50,470 --> 00:38:49,119 here 885 00:38:51,670 --> 00:38:50,480 okay 886 00:38:54,390 --> 00:38:51,680 so uh do you have any plans for 887 00:38:54,400 --> 00:38:57,750 yeah they are definitely 888 00:39:07,589 --> 00:38:59,030 i 889 00:39:10,150 --> 00:39:07,599 reconstruct the phylogeny or the 890 00:39:11,750 --> 00:39:10,160 evolutionary history of 891 00:39:14,150 --> 00:39:11,760 this gene 892 00:39:16,310 --> 00:39:14,160 but it's 893 00:39:24,230 --> 00:39:16,320 i 894 00:39:25,910 --> 00:39:24,240 but 895 00:39:27,109 --> 00:39:25,920 i need 896 00:39:30,390 --> 00:39:27,119 perhaps 897 00:39:32,310 --> 00:39:30,400 hundreds or thousands of sequences 898 00:39:35,109 --> 00:39:32,320 uh 899 00:39:40,230 --> 00:39:38,230 want to have a more robust analysis and 900 00:39:43,430 --> 00:39:40,240 uh 901 00:39:46,390 --> 00:39:43,440 i have looked in the literature and 902 00:39:48,470 --> 00:39:46,400 specifically for this gender as 903 00:39:51,160 --> 00:39:48,480 i have not found any 904 00:39:52,470 --> 00:39:51,170 revolutionary analysis 905 00:39:54,550 --> 00:39:52,480 [Music] 906 00:39:57,510 --> 00:39:54,560 let alone 907 00:39:58,870 --> 00:39:57,520 the phylogeny of this specific gene so i 908 00:40:01,270 --> 00:39:58,880 think 909 00:40:01,280 --> 00:40:05,349 i can publish if i 910 00:40:11,030 --> 00:40:08,069 reconstruct this phylogeny i think it 911 00:40:12,309 --> 00:40:11,040 can be published okay 912 00:40:14,470 --> 00:40:12,319 all right do we have any other questions 913 00:40:18,309 --> 00:40:14,480 anyone else 914 00:40:23,030 --> 00:40:19,829 what are the next steps for this line of 915 00:40:27,829 --> 00:40:24,870 what's your next step 916 00:40:29,430 --> 00:40:27,839 my my next step for using search 917 00:40:31,990 --> 00:40:29,440 for the line for this particular line of 918 00:40:36,309 --> 00:40:32,000 research for the results 919 00:40:41,750 --> 00:40:38,390 this was a very 920 00:40:46,790 --> 00:40:43,349 what i 921 00:40:50,309 --> 00:40:46,800 would need to do is to 922 00:40:54,230 --> 00:40:51,829 my sample 923 00:40:57,510 --> 00:40:56,150 because in this specific database there 924 00:40:59,829 --> 00:40:57,520 are 925 00:41:01,910 --> 00:40:59,839 i think around a thousand 926 00:41:04,230 --> 00:41:01,920 genomes 927 00:41:08,470 --> 00:41:04,240 i will need to 928 00:41:10,870 --> 00:41:08,480 if we look at the for example the 929 00:41:13,990 --> 00:41:10,880 ncbi database 930 00:41:16,390 --> 00:41:14,000 to which the pubmed resource belongs we 931 00:41:21,349 --> 00:41:18,150 tens of thousands of 932 00:41:23,829 --> 00:41:21,359 genomes so 933 00:41:25,829 --> 00:41:23,839 that would be a first step 934 00:41:28,230 --> 00:41:25,839 look in the 935 00:41:32,069 --> 00:41:28,240 tiger quantity of genomes that are 936 00:41:33,270 --> 00:41:32,079 available publicly publicly available 937 00:41:36,550 --> 00:41:33,280 and 938 00:41:41,589 --> 00:41:38,470 i think different 939 00:41:43,030 --> 00:41:41,599 structural analysis 940 00:41:46,470 --> 00:41:43,040 with 941 00:41:50,309 --> 00:41:46,480 more robust algorithms 942 00:41:52,790 --> 00:41:50,319 that uh can 943 00:41:55,750 --> 00:41:52,800 tell us more about the specific 944 00:42:01,430 --> 00:41:57,910 structure of this protein 945 00:42:01,440 --> 00:42:04,950 i i don't know 946 00:42:04,960 --> 00:42:09,030 i look but i 947 00:42:14,710 --> 00:42:11,270 what i have in mind is the 948 00:42:16,630 --> 00:42:14,720 evolutionary history of these genetics 949 00:42:18,069 --> 00:42:16,640 i think it's the that would be the next 950 00:42:21,829 --> 00:42:18,079 step 951 00:42:23,510 --> 00:42:21,839 and it will take a little while 952 00:42:24,470 --> 00:42:23,520 okay we only have a minute or two here 953 00:42:26,470 --> 00:42:24,480 um 954 00:42:28,150 --> 00:42:26,480 so a couple of quick questions first uh 955 00:42:31,750 --> 00:42:28,160 do you know if a gene for creativity has 956 00:42:34,150 --> 00:42:33,190 did you know 957 00:42:35,030 --> 00:42:34,160 that 958 00:42:39,109 --> 00:42:35,040 yeah 959 00:42:41,990 --> 00:42:40,470 is that a question 960 00:42:43,510 --> 00:42:42,000 that's a question yeah the question is 961 00:42:46,630 --> 00:42:43,520 whether you know whether or not a gene 962 00:42:47,750 --> 00:42:46,640 for creativity oh okay okay okay yeah 963 00:42:50,390 --> 00:42:47,760 uh 964 00:42:53,349 --> 00:42:52,069 i think there are 965 00:42:56,069 --> 00:42:53,359 there are 966 00:42:59,030 --> 00:42:56,079 some studies that 967 00:43:00,630 --> 00:42:59,040 for example are 968 00:43:03,589 --> 00:43:00,640 i remember one that 969 00:43:05,670 --> 00:43:03,599 has to do with a musical ability with 970 00:43:06,170 --> 00:43:05,680 relative musical ability 971 00:43:08,309 --> 00:43:06,180 and 972 00:43:09,750 --> 00:43:08,319 [Music] 973 00:43:10,790 --> 00:43:09,760 they found a 974 00:43:13,109 --> 00:43:10,800 uh 975 00:43:15,270 --> 00:43:13,119 i don't remember if it was a single gene 976 00:43:16,880 --> 00:43:15,280 or a 977 00:43:18,710 --> 00:43:16,890 couple of jeans there 978 00:43:19,990 --> 00:43:18,720 [Music] 979 00:43:23,349 --> 00:43:20,000 but 980 00:43:27,670 --> 00:43:25,829 talk about a more wider picture 981 00:43:29,829 --> 00:43:27,680 involving 982 00:43:32,950 --> 00:43:29,839 for example genius or 983 00:43:39,349 --> 00:43:36,870 i i do not know if there is some gene 984 00:43:41,829 --> 00:43:39,359 related to that there is 985 00:43:43,670 --> 00:43:41,839 for example this gene that 986 00:43:45,270 --> 00:43:43,680 has to do with 987 00:43:47,349 --> 00:43:45,280 religious 988 00:43:49,829 --> 00:43:47,359 experiences that 989 00:43:58,870 --> 00:43:49,839 i i don't know i don't remember the name 990 00:44:03,510 --> 00:44:00,230 all right if you can answer this uh 991 00:44:05,829 --> 00:44:03,520 relatively quickly uh if psy comes in on 992 00:44:08,710 --> 00:44:05,839 different perceptual channels you know 993 00:44:15,910 --> 00:44:08,720 visual auditory so on wouldn't there 994 00:44:21,109 --> 00:44:18,630 this is a complicated one because 995 00:44:24,550 --> 00:44:21,119 it's part of the 996 00:44:27,990 --> 00:44:25,910 tomorrow but 997 00:44:29,910 --> 00:44:28,000 uh 998 00:44:31,430 --> 00:44:29,920 so then we have people tune in tomorrow 999 00:44:33,349 --> 00:44:31,440 they can they can watch your session 1000 00:44:35,589 --> 00:44:33,359 tomorrow and and uh for the answer to 1001 00:44:41,030 --> 00:44:35,599 that 1002 00:44:44,470 --> 00:44:42,069 well 1003 00:44:45,829 --> 00:44:44,480 we so far we do not know 1004 00:44:48,470 --> 00:44:45,839 where does this 1005 00:44:51,030 --> 00:44:48,480 gene express well we know 1006 00:44:52,790 --> 00:44:51,040 it expressing some 1007 00:44:55,589 --> 00:44:52,800 specific brain gradients 1008 00:44:58,950 --> 00:44:56,710 we don't know 1009 00:45:00,550 --> 00:44:58,960 what uh 1010 00:45:04,950 --> 00:45:00,560 this 1011 00:45:05,990 --> 00:45:04,960 what the protein is doing perhaps it is 1012 00:45:07,430 --> 00:45:06,000 involving 1013 00:45:10,550 --> 00:45:07,440 making more 1014 00:45:11,510 --> 00:45:10,560
