To sleep, perchance (RenewAmerica columns)

Wed, 20 Aug 2008 18:57:43 GMT

(David Hines) - Is socialism in our genes? Perhaps -- in a manner of speaking. I was having a discussion with someone who has been reading up on epigenetics. This is a recent area of study. Temporary conditions alter how and whether genes are expressed. These changes are heritable. In one case study, a few families who suffered a food shortage were tracked...

Fri, 08 Aug 2008 12:00:00 GMT

Epigenetics: Principles of Eukaryotic Genome Control provides an integration of classical and molecular genetic perspectives to highlight underlying principles of gene and genome control in eukaryotes, with an emphasis on relevance for human disease. Among epigenetic phenomena discussed in this thorough treatment are imprinting, X chromosome inactivation, and DNA methylation, with specific examples...

Epigenetics in 1952-53 (Sandwalk)

Wed, 06 Aug 2008 14:27:00 GMT

This week's Citation Classics are, indeed, classics [This Week's Citation Classics: Host Induced Variation]. They were the first papers to describe a new form of non-Mendelian inheritance that eventually became well-understood at the molecular level. Today, scientists working on animal development think they have independently discovered this concept. They call it epigenetics. As John Dennehy...

... that Dawkins articulated," says Eric Richards, at Washington University in St Louis, Missouri. "Epigenetic marks can also be viewed as part of that basic unit in a more inclusive definition of a gene," he says.What does Dawkins himself think? "The 'transgenerational' effects now being described are mildly interesting, but they cast no doubt whatsoever on the theory of the selfish gene,"...

Epigenetics Revisited (Sandwalk)

Tue, 29 Jul 2008 12:18:00 GMT

I'm still struggling with the concept of epigenetics [see Epigenetics]. Most of the modern definitions are so broad that they become meaningless. It's impossible to distinguish between epigenetics and plain old regulation of gene expression. One of my colleagues, Craig Smibert, was so annoyed by my questions about epigenetics that he pointed me to a...

Epigenetics (Sandwalk)

Wed, 23 Jul 2008 20:44:00 GMT

Epigenetics is one of those words that means entirely different things to different people. P.Z. Myers has put up a nice description of the term on his blog [Epigenetics]. Here's how he defines epigenetics ... Epigenetics is the study of heritable traits that are not dependent on the primary sequence of DNA.In fairness, he then goes on to explain that this is an...

Is Your Lifestyle Affecting Your Future Child’s DNA? (Treehugger)

Wed, 23 Jul 2008 14:06:49 GMT

If I had a nickel for every prospective parent I know who changed their lifestyle for the better when they knew they were expecting I’d be a wealthy man indeed. But they just may be a bit late to the party. No pun intended. And that’s because a controversial new idea, called epigenetics, indicates those late nights in smoke filled rooms, that stress filled entry level job, or that apartment...

PZ Myers and Abbie Smith - An Hour of No Cursing! (Uncommon Descent)

Mon, 21 Jul 2008 09:57:38 GMT

PZ Myers and Abbie Smith have an hour-long video conference here. A few surprising things, not the least of which is neither of them thought to bolster their points with the cussing that characterizes their blogs. Anyhow, the first 15 minutes they talk about epigenetics, the Altenberg 16 conference, Susan Mazur, and try to downplay [...]

Techno-babble 'cause it will make no difference. "Overweight mothers give birth to offspring who become even heavier, resulting in amplification of obesity across generations, said Baylor College of Medicine researchers in Houston who found that chemical changes in the ways genes are expressed - a phenomenon called epigenetics - could affect successive generations of mice.

Epigenetics: Getting to the roots of mammalian imprinting (Nature Publishing Group)

Fri, 18 Jul 2008 10:12:12 GMT

A recent study has identified a complex imprinting mechanism that has been conserved for over 148 million years in therian mammals, which include placental mammals and marsupials. These findings suggest that, contrary to previous theories, imprinting by germline-derived methylation evolved before the advent of therian

Gene Expression in PLoS ONE (A Blog Around The Clock)

Tue, 08 Jul 2008 03:19:02 GMT

As you probably know by now, we have monthly themes in PLoS ONE. This month, the topic is Gene Expression , where there are more than 140 articles already, mainly looking at genome-wide expression and epigenetics. Of course, we want more. And I am still looking for a group to do a Journal Club on one of the related papers, so if you are interested, let me know. Read the comments on this post...

Nature and Nurture Linked by Epigenetics (Al Fin)

Wed, 25 Jun 2008 10:56:00 GMT

You cannot separate a person's genes from his environment. The two are irrevocably linked by several mechanisms. One of the most important ways in which the environment affects gene expression is via an epigenetic mechanism called "methylation." DNA methylation is always at work in the animal, initially helping guide differentiation and development of tissues and organs, and responding to the...
