1 00:00:00,613 --> 00:00:03,001 In 2003, 2 00:00:03,001 --> 00:00:06,032 when we sequenced the human genome, 3 00:00:06,032 --> 00:00:11,126 we thought we would have the answer to treat many diseases, 4 00:00:11,126 --> 00:00:14,289 but the reality is far from that, 5 00:00:14,289 --> 00:00:16,913 because in addition to our genes, 6 00:00:16,913 --> 00:00:19,619 our environment and lifestyle 7 00:00:19,619 --> 00:00:21,365 could have a significant role 8 00:00:21,365 --> 00:00:23,834 in developing many major diseases. 9 00:00:24,084 --> 00:00:27,680 One example is fatty liver disease, 10 00:00:27,680 --> 00:00:31,291 which is affecting over 20 percent of the population globally 11 00:00:31,291 --> 00:00:34,504 and it has no treatment and leads to liver cancer 12 00:00:34,504 --> 00:00:36,085 or liver failure. 13 00:00:36,806 --> 00:00:42,419 So sequencing DNA alone doesn't give us enough information 14 00:00:42,419 --> 00:00:44,753 to find effective therapeutics. 15 00:00:44,753 --> 00:00:48,559 On the bright side, there are many other molecules in our body. 16 00:00:48,559 --> 00:00:52,243 In fact, there are over 100,000 metabolites. 17 00:00:52,243 --> 00:00:57,104 Metabolites are any molecule that is super-small in their size. 18 00:00:57,104 --> 00:01:02,189 Known examples are glucose, fructose, fats, cholesterol, 19 00:01:02,189 --> 00:01:04,456 things we hear all the time. 20 00:01:04,456 --> 00:01:07,668 Metabolites are involved in our metabolism. 21 00:01:07,668 --> 00:01:12,312 They are also downstream of DNA, 22 00:01:12,312 --> 00:01:15,348 so they carry information from both our genes 23 00:01:15,348 --> 00:01:17,519 as well as lifestyle. 24 00:01:17,519 --> 00:01:23,150 Understanding metabolites is essential to find treatments for many diseases. 25 00:01:23,150 --> 00:01:26,046 I've always wanted to treat patients. 26 00:01:26,046 --> 00:01:30,032 Despite that, 15 years ago I left medical school, 27 00:01:30,032 --> 00:01:33,226 as I missed mathematics. 28 00:01:33,226 --> 00:01:36,367 Soon after, I found the coolest thing: 29 00:01:36,367 --> 00:01:39,130 I can use mathematics to study medicine. 30 00:01:41,201 --> 00:01:47,362 Since then, I've been developing algorithms to analyze biological data. 31 00:01:47,362 --> 00:01:49,710 So it sounded easy: 32 00:01:49,710 --> 00:01:53,254 let's collect data from all the metabolites in our body, 33 00:01:53,254 --> 00:01:58,355 develop mathematical models to describe how they are changed in a disease, 34 00:01:58,355 --> 00:02:01,524 and intervene those changes to treat them. 35 00:02:02,719 --> 00:02:06,907 Then I realized why no one has done this before. 36 00:02:06,907 --> 00:02:10,156 It's extremely difficult. 37 00:02:10,347 --> 00:02:12,783 There are many metabolites in our body. 38 00:02:12,783 --> 00:02:16,062 Each one is different from the other one. 39 00:02:16,062 --> 00:02:19,308 For some metabolites, we can measure their molecular mass 40 00:02:19,308 --> 00:02:22,032 using mass spectrometry instruments, 41 00:02:22,032 --> 00:02:26,342 but because there could be, like, 10 molecules with the exact same mass, 42 00:02:26,342 --> 00:02:28,143 we don't know exactly what they are, 43 00:02:28,143 --> 00:02:30,986 and if you want to clearly identify all of them, 44 00:02:30,986 --> 00:02:34,095 you have to do more experiments, which could take decades 45 00:02:34,095 --> 00:02:35,588 and billions of dollars. 46 00:02:35,588 --> 00:02:38,885 So we developed an artificial intelligence, 47 00:02:39,290 --> 00:02:42,074 or AI, platform to do that. 48 00:02:42,074 --> 00:02:45,162 We leveraged the growth of biological data 49 00:02:45,162 --> 00:02:49,352 and built a database of any existing information about metabolites 50 00:02:49,352 --> 00:02:52,525 and their interactions with other molecules. 51 00:02:52,762 --> 00:02:55,814 We combined all this data as a mega-network. 52 00:02:55,814 --> 00:02:59,025 then, from tissues or blood of patients, 53 00:02:59,025 --> 00:03:01,905 we measured masses of metabolites 54 00:03:01,905 --> 00:03:05,559 and find the masses that are changed in a disease. 55 00:03:05,559 --> 00:03:08,756 But, as I mentioned earlier, we don't know exactly what they are. 56 00:03:08,756 --> 00:03:13,753 Like a molecular mass of 180 could be the glucose, galactose, or fructose. 57 00:03:13,753 --> 00:03:15,804 They all have the exact same mass, 58 00:03:15,804 --> 00:03:18,009 but different functions in our body. 59 00:03:18,009 --> 00:03:21,540 Our AI algorithm considered all these ambiguities. 60 00:03:21,540 --> 00:03:24,285 It then mined that mega-network 61 00:03:24,285 --> 00:03:28,724 to find how those metabolic masses are connected to each other 62 00:03:28,724 --> 00:03:30,639 that result in disease, 63 00:03:30,639 --> 00:03:33,095 and because of the way they are connected, 64 00:03:33,095 --> 00:03:37,054 then we are able to infer what each metabolite mass is, 65 00:03:37,054 --> 00:03:39,934 like that 180 could be glucose here, 66 00:03:39,934 --> 00:03:44,344 and more importantly to discover how changes in glucose 67 00:03:44,344 --> 00:03:46,035 and other metabolites 68 00:03:46,035 --> 00:03:47,759 lead to a disease. 69 00:03:47,759 --> 00:03:51,270 This novel understanding of disease mechanisms 70 00:03:51,270 --> 00:03:55,196 then enable us to discover effective therapeutics to target that. 71 00:03:55,760 --> 00:03:59,542 So we formed a startup company to bring this technology to the market 72 00:03:59,542 --> 00:04:01,937 and impacts people's lives. 73 00:04:01,937 --> 00:04:05,474 Now, my team and I at ReviveMed are working to discover 74 00:04:05,474 --> 00:04:10,657 therapeutics for major diseases that metabolites are key drivers for, 75 00:04:10,853 --> 00:04:12,476 like fatty liver disease, 76 00:04:12,476 --> 00:04:15,823 because it is caused by accumulation of fats, 77 00:04:15,823 --> 00:04:17,455 which are types of metabolites, 78 00:04:17,455 --> 00:04:18,400 in the liver, 79 00:04:18,400 --> 00:04:21,967 and as I mentioned earlier is a huge epidemic with no treatment. 80 00:04:21,967 --> 00:04:24,762 And fatty liver disease is just one example. 81 00:04:24,762 --> 00:04:28,968 Moving forward, we are going to tackle hundreds of other diseases 82 00:04:28,968 --> 00:04:30,430 with no treatment, 83 00:04:30,430 --> 00:04:35,009 and by collecting more and more data about metabolites 84 00:04:35,009 --> 00:04:38,601 and understanding how changes in metabolites 85 00:04:38,601 --> 00:04:41,127 leads to developing diseases, 86 00:04:41,127 --> 00:04:44,449 our algorithms will get smarter and smarter 87 00:04:44,449 --> 00:04:48,821 to discover the right therapeutics for the right patients, 88 00:04:48,821 --> 00:04:52,716 and we will get closer to reach our vision 89 00:04:52,716 --> 00:04:56,383 of saving lives with every line of code. 90 00:04:56,383 --> 00:04:57,754 Thank you. 91 00:04:57,754 --> 00:05:01,581 (Applause)
