Abstract: Starvation, glucagon and cyclic AMP inhibit, and refeeding starved animals and insulin or IGF-I plus triiodothyronine stimulate accumulation of FAS and its mRNA in liver; transcription is the primary regulated step. In the uropygial gland, differentiation of basal cells into mature sebocytes is accompanied by the accumulation of large amounts of FAS and its mRNA. By analogy with liver, transcription is likely to be the regulated step, but direct experimental evidence for this hypothesis is lacking. FAS mRNA is a unique gene and is probably more...
