WEBVTT 00:00:00.613 --> 00:00:03.001 In 2003, 00:00:03.001 --> 00:00:06.032 when we sequenced the human genome, 00:00:06.032 --> 00:00:11.126 we thought we would have the answer to treat many diseases, 00:00:11.126 --> 00:00:14.289 but the reality is far from that, 00:00:14.289 --> 00:00:16.913 because in addition to our genes, 00:00:16.913 --> 00:00:19.619 our environment and lifestyle 00:00:19.619 --> 00:00:21.365 could have a significant role 00:00:21.365 --> 00:00:23.834 in developing many major diseases. NOTE Paragraph 00:00:24.084 --> 00:00:27.680 One example is fatty liver disease, 00:00:27.680 --> 00:00:31.291 which is affecting over 20 percent of the population globally 00:00:31.291 --> 00:00:34.504 and it has no treatment and leads to liver cancer 00:00:34.504 --> 00:00:36.085 or liver failure. 00:00:36.806 --> 00:00:42.419 So sequencing DNA alone doesn't give us enough information 00:00:42.419 --> 00:00:44.753 to find effective therapeutics. NOTE Paragraph 00:00:44.753 --> 00:00:48.559 On the bright side, there are many other molecules in our body. 00:00:48.559 --> 00:00:52.243 In fact, there are over 100,000 metabolites. 00:00:52.243 --> 00:00:57.104 Metabolites are any molecule that is super-small in their size. 00:00:57.104 --> 00:01:02.189 Known examples are glucose, fructose, fats, cholesterol, 00:01:02.189 --> 00:01:04.456 things we hear all the time. 00:01:04.456 --> 00:01:07.668 Metabolites are involved in our metabolism. 00:01:07.668 --> 00:01:12.312 They are also downstream of DNA, 00:01:12.312 --> 00:01:15.348 so they carry information from both our genes 00:01:15.348 --> 00:01:17.519 as well as lifestyle. 00:01:17.519 --> 00:01:23.150 Understanding metabolites is essential to find treatments for many diseases. NOTE Paragraph 00:01:23.150 --> 00:01:26.046 I've always wanted to treat patients. 00:01:26.046 --> 00:01:30.032 Despite that, 15 years ago I left medical school, 00:01:30.032 --> 00:01:33.226 as I missed mathematics. 00:01:33.226 --> 00:01:36.367 Soon after, I found the coolest thing: 00:01:36.367 --> 00:01:39.130 I can use mathematics to study medicine. 00:01:41.201 --> 00:01:47.362 Since then, I've been developing algorithms to analyze biological data. 00:01:47.362 --> 00:01:49.710 So it sounded easy: 00:01:49.710 --> 00:01:53.254 let's collect data from all the metabolites in our body, 00:01:53.254 --> 00:01:58.355 develop mathematical models to describe how they are changed in a disease, 00:01:58.355 --> 00:02:01.524 and intervene those changes to treat them. NOTE Paragraph 00:02:02.719 --> 00:02:06.907 Then I realized why no one has done this before. 00:02:06.907 --> 00:02:10.156 It's extremely difficult. 00:02:10.347 --> 00:02:12.783 There are many metabolites in our body. 00:02:12.783 --> 00:02:16.062 Each one is different from the other one. 00:02:16.062 --> 00:02:19.308 For some metabolites, we can measure their molecular mass 00:02:19.308 --> 00:02:22.032 using mass spectrometry instruments, 00:02:22.032 --> 00:02:26.342 but because there could be, like, 10 molecules with the exact same mass, 00:02:26.342 --> 00:02:28.143 we don't know exactly what they are, 00:02:28.143 --> 00:02:30.986 and if you want to clearly identify all of them, 00:02:30.986 --> 00:02:34.095 you have to do more experiments, which could take decades 00:02:34.095 --> 00:02:35.588 and billions of dollars. 00:02:35.588 --> 00:02:38.885 So we developed an artificial intelligence, 00:02:39.290 --> 00:02:42.074 or AI, platform to do that. 00:02:42.074 --> 00:02:45.162 We leveraged the growth of biological data 00:02:45.162 --> 00:02:49.352 and built a database of any existing information about metabolites 00:02:49.352 --> 00:02:52.525 and their interactions with other molecules. 00:02:52.762 --> 00:02:55.814 We combined all this data as a mega-network. 00:02:55.814 --> 00:02:59.025 then, from tissues or blood of patients, 00:02:59.025 --> 00:03:01.905 we measured masses of metabolites 00:03:01.905 --> 00:03:05.559 and find the masses that are changed in a disease. 00:03:05.559 --> 00:03:08.756 But, as I mentioned earlier, we don't know exactly what they are. 00:03:08.756 --> 00:03:13.753 Like a molecular mass of 180 could be the glucose, galactose, or fructose. 00:03:13.753 --> 00:03:15.804 They all have the exact same mass, 00:03:15.804 --> 00:03:18.009 but different functions in our body. 00:03:18.009 --> 00:03:21.540 Our AI algorithm considered all these ambiguities. 00:03:21.540 --> 00:03:24.285 It then mined that mega-network 00:03:24.285 --> 00:03:28.724 to find how those metabolic masses are connected to each other 00:03:28.724 --> 00:03:30.639 that result in disease, 00:03:30.639 --> 00:03:33.095 and because of the way they are connected, 00:03:33.095 --> 00:03:37.054 then we are able to infer what each metabolite mass is, 00:03:37.054 --> 00:03:39.934 like that 180 could be glucose here, 00:03:39.934 --> 00:03:44.344 and more importantly to discover how changes in glucose 00:03:44.344 --> 00:03:46.035 and other metabolites 00:03:46.035 --> 00:03:47.759 lead to a disease. 00:03:47.759 --> 00:03:51.270 This novel understanding of disease mechanisms 00:03:51.270 --> 00:03:55.196 then enable us to discover effective therapeutics to target that. 00:03:55.760 --> 00:03:59.542 So we formed a startup company to bring this technology to the market 00:03:59.542 --> 00:04:01.937 and impacts people's lives. NOTE Paragraph 00:04:01.937 --> 00:04:05.474 Now, my team and I at ReviveMed are working to discover 00:04:05.474 --> 00:04:10.657 therapeutics for major diseases that metabolites are key drivers for, 00:04:10.853 --> 00:04:12.476 like fatty liver disease, 00:04:12.476 --> 00:04:15.823 because it is caused by accumulation of fats, 00:04:15.823 --> 00:04:17.455 which are types of metabolites, 00:04:17.455 --> 00:04:18.400 in the liver, 00:04:18.400 --> 00:04:21.967 and as I mentioned earlier is a huge epidemic with no treatment. NOTE Paragraph 00:04:21.967 --> 00:04:24.762 And fatty liver disease is just one example. 00:04:24.762 --> 00:04:28.968 Moving forward, we are going to tackle hundreds of other diseases 00:04:28.968 --> 00:04:30.430 with no treatment, 00:04:30.430 --> 00:04:35.009 and by collecting more and more data about metabolites 00:04:35.009 --> 00:04:38.601 and understanding how changes in metabolites 00:04:38.601 --> 00:04:41.127 leads to developing diseases, 00:04:41.127 --> 00:04:44.449 our algorithms will get smarter and smarter 00:04:44.449 --> 00:04:48.821 to discover the right therapeutics for the right patients, 00:04:48.821 --> 00:04:52.716 and we will get closer to reach our vision 00:04:52.716 --> 00:04:56.383 of saving lives with every line of code. NOTE Paragraph 00:04:56.383 --> 00:04:57.754 Thank you. NOTE Paragraph 00:04:57.754 --> 00:05:01.581 (Applause)
