Things like this get me really excited to be in medicine. Epigenetics is an amazing new field, that I was lucky enough to read about in depth this past year doing research on HPV, that looks at the post-translational genetic modification of genes. For example: there are two identical twins, with the same DNA. One develops rheumatoid arthritis. The other doesn’t. Turns out, the one who did develop rheumatoid arthritis might have four genes methylated that are related to the immune response. The other doesn’t.
One of those genes, C6orf10, is a novel find and a new addition to the set we already knew affected rheumatoid arthritis. Not too shabby.
But now, I really must get back to memorizing the hormonal control of glycolysis and all that stuff. I know it’s on the STEP1, so I can no longer tell myself I don’t really need to know it in the long run. Also, Action Potential’s post on studying for the STEP1 is helping me remember that I actually do need to learn this now.
