Abstract excerpt
Two leading hypotheses to explain lithium action in bipolar disorder propose either inositol depletion or inhibition of GSK-3 as mechanisms of action. Behavioral effects of lithium are mimicked in Gsk-3beta+/- mice, but the contribution of inositol depletion to these behaviors has not been tested. According to the inositol depletion hypothesis, lithium-sensitive behavior is secondary to impaired...
