Circadian Genes Differentially Affect Tolerance to Ethanol in Drosophila

There is a strong relationship between circadian rhythms and ethanol (EtOH) responses. EtOH consumption has been shown to disrupt physiological and behavioral circadian rhythms in mammals (Alcohol Clin Exp Res 2005b, 29, 1550). The Drosophila central circadian pacemaker is composed of proteins encoded by the per, tim, cyc, and Clk genes. Using Drosophila mutant analysis, we asked whether these
