Adenovirus’s epigenetic power to reprogram cells goes beyond its ability to cause tumorous replication — G.J. Fonseca and colleagues at the Western University of Ontario report in the new Cell Host & Microbe that it’s also able to sabotage the interferon response, which usually functions as a first line of defense in infected cells. In an April post, I interviewed Roberto Ferrari about adenovirus research and its ability to push cells back into active tumor-like replication, so I thought this bit of news was an interesting incremental step in overall knowledge of how invaders — particularly adenovirus — use epigenetics against us. What a bunch of jerks! In particular, Fonseca and colleagues used a yeast two-hybrid screen to find out … Continue reading

To my mild shame, I watched a little of the Oscars the other night. We’re all familiar with many of these folks, but we don’t see them very often, so it’s especially striking as they age from svelte starlet to grand dame, or what have you. The stages seem to come in rapid succession. Ol’ Nick Nolte just turned 72! He was way more spry — but equally gruff — 30 years ago, in the 1982 hit 48 Hours. And how he’s changed since those hijinks of only 10 years ago. (See, it’s not always for the worse.) So what’s different about Nick Nolte’s epigenome now, versus when he played opposite wise-cracking trickster Eddie Murphy? Could you guess his age … Continue reading

Reader Della writes us on Twitter about two epigenetics tangents—diets for healthier gene expression and beliefs to hold (or “perceptions to gather,” I guess) for healthier gene expression. As it turns out, a few of us here at E3 were talking* about the epigenetics-diet connection too, so I’ll take a crack at the viewpoint in that Globe and Mail link above, which is based on this Clinical Epigenetics review by Syed Meeran and collegues at the University of Alabama. I’m sure we won’t neglect subject of epigenetics and beliefs for very long. The Globe and Mail article mentions the anti-cancer properties of broccoli, green tea, soy, grapes, tumeric, rosemary, and garlic. It also talks up the epigenetic benefits of a … Continue reading
