Mayo Clinic Researchers Discover Genetic Markers for Alcoholism Recovery

05.11.2014

In an international study, Mayo Clinic researchers and collaborators have identified genetic markers that may help in identifying individuals who could benefit from the alcoholism treatment drug acamprosate. The findings, published in the journal Translational Psychiatry, show that patients carrying these genetic variants have longer periods of abstinence during the first three months of acamprosate treatment.

Acamprosate is a commonly prescribed drug used to aid patients in recovery from alcoholism. Mayo researchers studied the association between variation in candidate genes and the length of sobriety in alcohol-dependent patients treated with acamprosate in community-based programs.

They found that, when other environmental and physiological factors were considered, patients with the common allele of the genetic variant rs2058878 located in the GRIN2B gene, stayed sober more days than those with a variant allele of the same polymorphism. This finding was replicated in a sample of alcohol-dependent patients treated with acamprosate in a study conducted by collaborators from Germany.

“This association finding is a first step towards development of a pharmacogenetic test allowing physicians to choose appropriate treatment for specific subgroups of alcohol-dependent patients,” says Victor Karpyak, M.D., Ph.D., Mayo Clinic psychiatrist and lead author of the article. “We believe that individualized treatment selection will eliminate the need for trial-and-error approaches and improve treatment efficacy in patients with alcohol use disorders.”

The Mayo findings support evidence implicating an important role of the N-Methyl-D-aspartate (NMDA) receptors in the treatment effects of acamprosate. The researchers say more studies are needed to determine potential importance of identified genetic variants in the longer-term effects of acamprosate, as well as the molecular and physiological mechanisms behind the drug’s action.

The study was funded in part by the Mayo Clinic Center for Individualized Medicine; the SC Johnson Genomics of Addiction Program at Mayo Clinic; the National Institutes of Health; the National Center for Advancing Translational Sciences; the National Genome Research Network of the German Federal Ministry of Education and Research; the Bundesministerium für Bildung und Forschung; and the Alfred Krupp von Bolen und Halbach-Stiftung (Foundation).

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
