A New Epigenetic Brain Defense Against Recurrence of Opioid Use

HDAC5, the "epigenetics" enzyme, plays a key role in limiting opioid-associated memories and drug-seeking behaviors following abstinence from drugs in rats. The findings provide a new avenue for the treatment of opioid addiction.

Dial for Tuning Dopamine and Environmental Signals Found in Parkinson’s

Study reveals how signals from the environment integrate with genetic information that influences the survival and health of neurons, providing new insights into how Parkinson's disease may develop. Findings reveal the TNK2 gene mutations lead to the degeneration of dopamine producing neurons, resulting in Parkinson's disease pathology.

Loss of Epigenetic Information Can Drive Aging, Restoration Can Reverse It

Epigenetics can drive aging in an organism, independently of alterations in the genetic code itself. The breakdown of epigenetic information results in aging in mice, yet restoring the integrity of the epigenome reverses signs of aging.

Twin Study Links Exercise to Beneficial Epigenetic Changes

Twins who were more physically active had lower signs of metabolic disease and epigenetic markers linked to decreased risk of metabolic syndrome. Findings suggest metabolic diseases are strongly influenced by how a person interacts with their environment as opposed to just their inherited genetics.

Epigenetic Changes Linked to Parkinson’s Disease Differ in Men and Women

Post-mortem analysis of the brains of those with Parkinson's disease revealed more than 200 genes with different epigenetic markers compared to healthy brains, but the affected genes were almost entirely different between women and men.
