Alcoholism: Is It All in the Genes?

Dienstag 1. März 2011 von htm

We know alcoholism runs in families — children with alcoholic parents have quadruple the risk of developing a drinking problem later in life than those without — but is the link genetic or the result of other influences?
According to a Feb. 8 Wall Street Journal article outlining the evidence for „alcoholism genes,“ it is probably both. Researchers from the Collaborative Study on the Genetics of Alcoholism, a 22-year National Institute on Alcohol Abuse and Alcoholism (NIAAA) investigation into the relationship between DNA and alcoholism, have put together compelling evidence from family studies indicating the problem has roots in nature versus nurture. … (Source: Join Together, 02/28/11)

In Search of Alcoholism Genes

Freitag 11. Februar 2011 von htm

Identifying Links to Drinking May Lead to Drug Treatments Tailored to Your DNA.
Millions of Americans know all too painfully that alcoholism runs in families.
Children of alcoholic parents are four times as likely to develop drinking problems as the general population. Sons of alcoholic fathers face up to nine times the usual risk. Even babies of alcoholics adopted into non-drinking homes have nearly the same risk of alcoholism as they would if they’d stayed with their biological parents, studies have shown.
But untangling just which genes pass along the predisposition for problem drinking is devilishly difficult—largely because alcoholism itself is so complex. Genes that affect how fast the liver metabolizes alcohol and how the brain reacts to stress, reward and pleasure have all been implicated, as have genes for anxiety and depression. Some overlap with genes for nicotine, cocaine and other addictions. … Source: Alcohol Reports, 02/07/11) online.wsj.com, 02/08/11

First Direct Evidence That Response To Alcohol Depends On Genes

Samstag 23. Oktober 2010 von htm

Many studies have suggested that genetic differences make some individuals more susceptible to the addictive effects of alcohol and other drugs. Now scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory provide the first experimental evidence to directly support this idea in a study in mice reported in the October 19, 2010, issue of Alcoholism Clinical Experimental Research.

Are Teen Binge Drinkers Risking Future Osteoporosis?

Freitag 16. Juli 2010 von htm

Binge-drinking teenagers may be putting themselves at risk for future osteoporosis and bone fractures, according to researchers at Loyola University Health System. A new Loyola study has found long-lasting disruptions in hundreds of genes involved in bone formation in rats. The study is published in the July-August issue of the journal Alcohol and Alcoholism.

Early First Drink May Modify Youth Risk For Alcohol Dependence

Montag 21. September 2009 von htm

Individuals who begin drinking at an early age are more likely to subsequently develop alcohol dependence (AD). While age at first drink (AFD) and AD are influenced by similar genetic and environmental factors, AFD may also have an impact on the risk for AD. A new study has found that AFD may facilitate the expression of genes that are already associated with vulnerability to AD symptoms. Results will be published in the December issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View. (Source: Medical News Today, 9/21/09)
