#1. 나이와 신분이 중요한 게 아니다.

by Yoon_Med 2014. 2. 22.



Have you ever experienced a moment in your life that was so painful and confusing that all you wanted to do was learn as much as you could to make sense of it all?당신은 인생을 살면서 너무도 고통스럽고 혼란스러워서 그저 할 수 있는 것이라곤 상황을 이해하기 위해 최선을 다해 공부하는 것 뿐인 상황을 겪어 본 적이 있습니까? 

0:24When I was 13, a close family friend who was like an uncle to me passed away from pancreatic cancer. When the disease hit so close to home, I knew I needed to learn more, so I went online to find answers.제가 13살 때, 저에게는 삼촌과도 같은 친구가 췌장암으로 죽었습니다. 그 병이 남일 같지가 않아서, 저는 더 공부를 해야될 필요성을 느꼈고 답을 찾기 위해 인터넷을 찾았습니다. 

0:39Using the Internet, I found a variety of statistics on pancreatic cancer, and what I had found shocked me. Over 85 percent of all pancreatic cancers are diagnosed late, when someone has less than a two percent chance of survival. Why are we so bad at detecting pancreatic cancer? The reason? Today's current modern medicine is a 60-year-old technique. That's older than my dad.인터넷 검색을 하면서, 췌장암에 대한 다양한 통계를 찾았고 그것을 저를 놀라게 했습니다. 85% 이상의 췌장암이 늦게 진단된다는 것입니다. 그때는 5년 생존율이 2%도 안되구요. 우리는 왜 췌장암 진단을 그렇게 못할까요? 이유요? 오늘날의 현대 의학은 60년 묵은 기술이니까요. 심지어 우리 아빠보다 오래됬어요.

1:08(Laughter)

1:12But also, it's extremely expensive, costing 800 dollars per test, and it's grossly inaccurate, missing 30 percent of all pancreatic cancers. Your doctor would have to be ridiculously suspicious that you have the cancer in order to give you this test. Learning this, I knew there had to be a better way. So I set up a scientific criteria as to what a sensor would have to look like in order to effectively diagnose pancreatic cancer. The sensor would have to be inexpensive, rapid, simple, sensitive, selective, and minimally invasive.또한, 그것은 엄청나게 비싸요. 한번 검사하는데 800달러가 들고, 30%의 췌장암을 놓칠 정도로 굉장히 부정확해요. 당신의 의사가 이런 검사를 하기 위해서는 우스꽝스럽게도 당신이 췌장암이 의심되어야 해요.이것을 알게되면서, 더 나은 방법이 있어야 겠다는걸 알게 되었어요. 그래서 저는 과학적 기준을 정립했죠. 췌장암의 효과적 진단을 위해서는 센서가 필요하다는 것을요. 이 센서는 저렴하고, 신속하며, 간단하고 선택적이며 비침습적이어야 되죠. 

1:52Now, there's a reason why this test hasn't been updated in over six decades, and that's because, when we're looking for pancreatic cancer, we're looking at your bloodstream, which is already abundant in all these tons and tons of protein, and you're looking for this miniscule difference in this tiny amount of protein, just this one protein. That's next to impossible.

2:14However, undeterred due to my teenage optimism -- (Applause) — I went online to a teenager's two best friends, Google and Wikipedia. I got everything for my homework from those two sources. And what I had found was an article that listed a database of over 8,000 different proteins that are found when you have pancreatic cancer. So I decided to go and make it my new mission to go through all these proteins and see which ones could serve as a biomarker for pancreatic cancer. And to make it a bit simpler for myself, I decided to map out a scientific criteria. And here it is. Essentially first, the protein would have to be found in all pancreatic cancers at high levels in the bloodstream in the earliest stages, but also only in cancer.

3:08And so I'm just plugging and chugging through this gargantuan task, and finally, on the 4,000th try,when I'm close to losing my sanity, I find the protein. And the name of the protein I'd located was called mesothelin, and it's just your ordinary, run-of-the-mill type protein, unless of course you have pancreatic, ovarian or lung cancer, in which case it's found at these very high levels in your bloodstream. But also the key is that it's found in the earliest stages of the disease, when someone has close to 100 percent chance of survival.

3:39So now that I'd found a reliable protein I could detect, I then shifted my focus to actually detecting that protein, and, thus, pancreatic cancer. Now, my breakthrough came in a very unlikely place, possibly the most unlikely place for innovation: my high school biology class, the absolute stifler of innovation.

3:59(Laughter) (Applause)

4:04And I had snuck in this article on these things called carbon nanotubes, and that's just a long, thin pipe of carbon that's an atom thick and one 50 thousandth the diameter of your hair. And despite their extremely small sizes, they have these incredible properties. They're kind of like the superheroes of material science. And while I was sneakily reading this article under my desk in my biology class, we were supposed to be paying attention to these other kind of cool molecules called antibodies. And these are pretty cool because they only react with one specific protein, but they're not nearly as interesting as carbon nanotubes. And so then, I was sitting in class, and suddenly it hit me: I could combine what I was reading about, carbon nanotubes, with what I was supposed to be thinking about, antibodies. Essentially, I could weave a bunch of these antibodies into a network of carbon nanotubessuch that you have a network that only reacts with one protein, but also, due to the properties of these nanotubes, it would change its electrical properties based on the amount of protein present.

5:07However, there's a catch. These networks of carbon nanotubes are extremely flimsy, and since they're so delicate, they need to be supported. So that's why I chose to use paper. Making a cancer sensor out of paper is about as simple as making chocolate chip cookies, which I love. You start with some water, pour in some nanotubes, add antibodies, mix it up, take some paper, dip it, dry it, and you can detect cancer.

5:37(Applause)

5:44Then, suddenly, a thought occurred that kind of put a blemish on my amazing plan here. I can't really do cancer research on my kitchen countertop. My mom wouldn't really like that. So instead, I decided to go for a lab. So I typed up a budget, a materials list, a timeline, and a procedure, and I emailed it to 200 different professors at Johns Hopkins University and the National Institutes of Health, essentially anyone that had anything to do with pancreatic cancer. And I sat back waiting for these positive emails to be pouring in, saying, "You're a genius! You're going to save us all!"

6:20And — (Laughter)

6:24Then reality took hold, and over the course of a month, I got 199 rejections out of those 200 emails.One professor even went through my entire procedure, painstakingly -- I'm not really sure where he got all this time -- and he went through and said why each and every step was like the worst mistake I could ever make. Clearly, the professors did not have as high of an opinion of my work as I did.

6:50However, there was a silver lining. One professor said, "Maybe I might be able to help you, kid." So I went in that direction.

6:58(Laughter)

7:02As you can never say no to a kid.

7:05And so then, three months later, I finally nailed down a harsh deadline with this guy, and I get into his lab, I get all excited, and then I sit down, I start opening my mouth and talking, and five seconds later he calls in another Ph.D. Ph.D.'s just flock into this little room, and they're just firing these questions at me,and by the end, I kind of felt like I was in a clown car. There were 20 Ph.D.'s plus me and the professorcrammed into this tiny office space with them firing these rapid-fire questions at me, trying to sink my procedure. How unlikely is that? I mean, pshhh.

7:39(Laughter)

7:43However, subjecting myself to that interrogation, I answered all of their questions, and I guessed on quite a few but I got them right, and I finally landed the lab space I needed.

7:54But it was shortly afterwards that I discovered my once brilliant procedure had something like a million holes in it, and over the course of seven months, I painstakingly filled each and every one of those holes.

8:05The result? One small paper sensor that costs three cents and takes five minutes to run. This makes it 168 times faster, over 26,000 times less expensive, and over 400 times more sensitive than our current standard for pancreatic cancer detection.

8:23(Applause)

8:33One of the best parts of the sensor, though, is that it has close to 100 percent accuracy, and can detect the cancer in the earliest stages when someone has close to 100 percent chance of survival. And so in the next two to five years, this sensor could potentially lift for pancreatic cancer survival rates from a dismal 5.5 percent to close to 100 percent, and it would do similar for ovarian and lung cancer.

8:56But it wouldn't stop there. By switching out that antibody, you can look at a different protein, thus, a different disease, potentially any disease in the entire world. So that ranges from heart disease to malaria, HIV, AIDS, as well as other forms of cancer -- anything.

9:15And so hopefully one day we can all have that one extra uncle, that one mother, that one brother, sister,we can have that one more family member to love, and that our hearts will be rid of that one disease burden that comes from pancreatic, ovarian and lung cancer, and potentially any disease, that through the Internet anything is possible. Theories can be shared, and you don't have to be a professor with multiple degrees to have your ideas valued. It's a neutral space, where what you look like, age or gender, it doesn't matter. It's just your ideas that count. For me, it's all about looking at the Internet in an entirely new way to realize that there's so much more to it than just posting duck-face pictures of yourself online. You could be changing the world.

10:07So if a 15-year-old who didn't even know what a pancreas was could find a new way to detect pancreatic cancer, just imagine what you could do.

10:18Thank you.

10:19(Applause)
