Alcohol Abuse Makes ‘Epigenetic Clock’ Run Faster

Study Finds Heavy Alcohol Use Accelerates Cellular Aging

Tuesday, October 29, 2019

old clock

In an era when 80-year-olds are running marathons while 30-year-olds suffer from obesity-induced heart attacks, inferring the condition of people’s bodies from their birth years is a bit outdated (pun intended). As a result, scientists and clinicians are increasingly examining biological signposts to gauge how well a person’s tissues are functioning. By looking at chemical markers on DNA, IRP researchers recently found that heavy alcohol use accelerates aging at the cellular level.

Stress-Relieving Chemical Could Combat Alcohol Use Disorder

Targeting Brain’s Stress Circuitry Curbs Rats’ Alcohol Consumption

Tuesday, August 6, 2019

chemical structure of the oxytocin molecule

For social drinkers, alcohol brings to mind barbecues and bar-hopping with friends, but for the roughly 16 million Americans with alcohol use disorder (AUD), drinking is a source of significant stress. Unfortunately, those negative emotions — particularly those experienced during withdrawal — drive people with AUD to drink even more. A recent IRP study points to a potential way to curb the desire to drink in people who abuse alcohol by altering the behavior of a brain structure that governs negative emotions.
