Glycerol-3-phosphate dehydrogenase mRNA content in cultured 3T3-L1 adipocytes: regulation by dibutyryl cyclic AMP.
Incubation of differentiated 3T3-L1 adipocytes with 0.5 mM dibutyryl cAMP plus 0.5 mM theophylline for 2 hours results in an 85% decrease in glycerol-3-phosphate dehydrogenase (G3PD) mRNA content. Incubation of the adipocytes with insulin (1 microgram/ml) up to 24 hrs yielded no significant change in the G3PD mRNA content compared with control.
