Genes Are Not Fixed, Experience and Exposure Can Change Them
Newswise — Epigenetics refers to how certain life circumstances can cause genes to be silenced or expressed, become dormant or active, over time. New research shows that adolescent binge drinking can lead to epigenetic reprogramming that predisposes an individual to later psychiatric disorders such as anxiety. These data will be shared at the 40th annual scientific meeting of the Research Society on Alcoholism (RSA) in Denver June 24-28.
“Adolescence is an important period of growth,” said Subhash C. Pandey, Ph.D., professor and director of the Alcohol Research Center at the University of Illinois Chicago. “This is when the brain is maturing, and consistent epigenetic programing occurs. This is also a period when binge drinking is prevalent. Adolescent binge drinking can disrupt epigenetic programing in key brain regions by changing certain key molecular targets within the epigenome.”
