Dihydrocytochalasin B promotes adipose conversion of 3T3 cells

Abstract
Differentiation of preadipose 3T3-F442A cells into adipose cells is accelerated by the addition of dihydrocytochalasin B. The effect of the drug on 3T3-C2 cells is more marked: these cells are practically unable to differentiate in the absence of H2CB but a long-term exposure to the drug enables the cells to accumulate lipid droplets in medium supplemented with fetal calf serum and insulin. During their differentition under these conditions the 3T3-C2 cells develop markers typical of adipose cells; glycerophosphate dehydrogenase, ATP-citrate lyase, fatty acid synthetase and glycerophosphate acyltransferase.
