Prof. Randy Jirtle discusses epigenetics and health
February 23, 2010 at 7:03 pm | Posted in Video | 4 CommentsThis is an excellent video of Professor Randy Jirtle of Duke University explaining the science of epigenetics – how genes are switched on and off in the cell nucleus, and how these processes can be interfered with to the potential detriment (but also benefit) of our health.
For example, Jirtle describes how the agouti gene in mice, if inappropriately expressed through manipulation of epigenetic processes, stops a mouse from recognising when it is full, causing it to eat its way to obesity.

Excellent talk.
The volume of the audio is very low. I had to crank it way up to hear it.

Glad you liked the talk – we are aware of the audio issue. The video streams from YouTube where it was posted by Duke University, so we have no control over the problem.
