Ethanol exposure led to glucose intolerance, elevated plasma insulin, compromised cardiac contractile and intracellular Ca2+ properties, downregulated protein phosphatase PP2A subunit and PPAR-γ, as well as phosphorylation of AMPK, ACC and LKB1, all of which except plasma insulin were overtly accentuated by ADH transgene. Here, INS is linked to Glucose intolerance.
