closeEpigenetics and the environment
Posted by CeliaMRoss on 25 Jul 2014 at 10:46 GMT
I found the article by Breton et al (2014) to be fascinating. (1) Breton et al (2014) made an important step toward investigating a possible mechanism, epigenetic disruption, by which tobacco smoke could lead to chronic health problems. For years I have speculated about the possible role of epigenetic modifiers in the environment in influencing chronic disease risk. (2, 3, 4) It is good to see more investigations concerning this. This is a very important article on a very important topic, well-done Breton et al.
