FABP4 and Glucose intolerance: Although we could not elucidate whether rDDT affects tissues other than adipose tissue, increased Ser-565 and decreased Ser-660 phosphorylation of HSL, resulting in its lower activity, and the decrease of FABP4 expression in the adipose tissue from rDDT-treated db/db mice suggest that the actions of DDT on adipocytes contribute to the improvement in glucose intolerance.
