Frequent Cocaine Use Linked to Alterations in DNA: Findings May Provide Insight Into Underlying Mechanisms of Addictive Behavior

Pin It

Regular cocaine use can affect DNA transcription networks and chromatin remodeling across the genome, according to a new study published online February 7 in Proceedings of the National Academy of Sciences of the United States of America.

The study suggests that derepressing parts of the genome by cocaine use can alter patterns of gene transcription in specific neuron types, affecting their drug sensitivity……..
