No, thats your reflectionNEIL DEGRASSE TYSON And even if you. The synchrony in your. CLOTILDE When I see my sister, I see myself. If she looks. good, I think, I look pretty today. But if shes not. I say, My god, I look horribleNEIL DEGRASSE TYSON Its hardly. You have precisely the same. And you are literally clones, better known, as identical twins. But. now, imagine this one day, your twin, your clone, is diagnosed with cancer. Cort Thinking Program' title='Cort Thinking Program' />If. CLOTILDE I have been told that I am a high risk for cancer. Damocles sword hangs over me. NEIL DEGRASSE TYSON And yet, its. Ana Mari, to get a dread disease, while the. Clotilde, doesnt. But how can two people so alike, be so. Their DNA is as identical as Ana Mari and. Clotildes despite the differences in their color and size. The human who. studies them is Duke Universitys Randy Jirtle. So. Randy, I see here you have skinny mice and fat mice. What have you done in this. JIRTLE Well. these animals are actually genetically identical. NEIL DEGRASSE TYSON The fat ones and. RANDY. JIRTLE Thats. NEIL DEGRASSE TYSON Because these are. Six Thinking Hats Course. In Six Thinking Hats System, there are six hats with different colors and each hat represent a mode of thinking.

CHEERFUL NEIL DEGRASSE TYSON Did you ever notice that if you get to know two identical twins, they might look alike, but. JIRTLE Theyre. NEIL DEGRASSE TYSON Can we weigh them. RANDY. JIRTLE Sure. So. if you take this. NEIL DEGRASSE TYSON It looks like they. RANDY. JIRTLE They. Theyre not going to be running very far. So. thats about 6. NEIL DEGRASSE TYSON 6. RANDY. JIRTLE Lets. NEIL DEGRASSE TYSON So its half. RANDY. JIRTLE Right. NEIL DEGRASSE TYSON This gets even more. So. what accounts for the thin mouse Exercise AtkinsNo, a tiny chemical tag of. Living creatures possess millions of tags like these. Some. like methyl groups, attach to genes directly, inhibiting their function. Other. types grab the proteins, called histones, around which genes coil, and tighten. Distinct methylation and histone. RANDY. JIRTLE Epigenetics. So if. you would think, for example, of the genome as being like a computer, the. NEIL DEGRASSE TYSON In fact, its. Skin Hair Heart You see, all these cells have the same genes. But their epigenomes. Epigenetic. instructions pass on as cells divide, but theyre not necessarily. Researchers think they can change, especially during critical. Jirtles. mice reveal how the epigenome can be altered. To produce thin, brown mice. RANDY. JIRTLE And I. NEIL DEGRASSE TYSON And that matters. RANDY. JIRTLE Thats. NEIL DEGRASSE TYSON. RANDY. JIRTLE Thats. NEIL DEGRASSE TYSON This epigenetic fix. And when an environmental toxin was added to the diet instead of. RANDY. JIRTLE It does. If there are genes like this in humans, basically, what you. So youre not only what you eat. NEIL DEGRASSE TYSON So how do you go to. RANDY. JIRTLE Thats. NEIL DEGRASSE TYSON So, who is your. RANDY. JIRTLE Well, then. NEIL DEGRASSE TYSON Twins, twins. And. that brings us to the reason why were showing you Spanish twins. In. 2. 00. 5, they participated in a groundbreaking study in Madrid. Its aim To show. MANEL. ESTELLER Spanish National Cancer Center One of the questions of twins is, If my twin. I will have the same disease And genetics tell us that. But its not really. Something has to regulate these genes, and part of the explanation is. NEIL DEGRASSE TYSON Esteller wanted to. To find. out, he and his team collected cells from 4. DNA, the master molecule that contains our. DNA, until the genes themselves became. Those that had been turned off epigenetically appear as dark pink. Now, notice what happens when the genes from a pair of twins. The. results are far from subtle, especially when you compare the epigenomes of two. Here, on the left, is the overlapped DNA of. Javier and Carlos. The yellow indicates where their gene. On. the right, is the DNA of 6. Ana Mari and Clotilde. In contrast to the. Their epigenomes have changed. The. study suggests that, as twins age, epigenetic differences accumulate. MANEL. ESTELLER One of the main findings of our. And this is one of the key differences between. NEIL DEGRASSE TYSON As the chemical. Take a disorder like MDS, cancer of the blood and bone. Its not a diagnosis youd ever want to hear. SANDRA. SHELBY When I went in, he started patting. Your blood work does not look very good at. I had MDS leukemia, and that there was not a cure for it. And, basically, I had six months to live. NEIL DEGRASSE TYSON Was epigenetics the. Could the silencing of critical genes turn normal cells into cancerous. Its scary to think that a few misplaced tags can kill you. But. its also good news, because weve traditionally viewed cancer as a. And its a lot harder to fix. In fact, we already have a few. Recently, Sandra Shelby and Roy Cantwell participated in. JEAN PIERRE. ISSA M. D. Anderson Cancer Center The idea of epigenetic therapy is to stay away from. Rather, what we are trying to do is diplomacy, trying to. Hey. youre a human cell. You shouldnt be behaving this way. And. SANDRA. SHELBY The results have been incredible, and. I didnt have really any horrible side effects. ROY. CANTWELL I am in remission. And going in. the plus direction is a whole lot better than the minus direction. NEIL DEGRASSE TYSON In fact, half the. But, while it maybe easier to fix. RANDY. JIRTLE Weve. They have a responsibility. Their genome they inherit. But their epigenome, they. And that brings. in responsibility, but it also brings in hope. Youre not necessarily. You can alter this.
