A new study has found that targeting
a protein might allow treatment of alcoholism
and simultaneously prevent alcohol-induced heart
and liver damage.
The protein called RGS6 acts through two separate mechanisms to control alcohol-seeking behaviour and alcohol-induced cell death in heart, liver, and other organs, the findings showed.
Lead researcher Rory Fisher from the University of Iowa in the US said, "We propose that inhibiting this RGS6 protein could represent a new approach to counteract alcohol dependence and at the same time protect against the cell-killing actions of alcohol in the heart and liver."
The scientists used mice lacking RGS6 to probe the protein's roles in both alcohol craving and organ damage.
They found that when given free access to alcohol, mice without the RGS6 protein consumed less alcohol than wild-type mice with the concerned protein. The study appeared online in the journal Early Edition of the Proceedings of the National Academy of Sciences (PNAS).
