Effect of phorbol myristate acetate on cyclic nucleotide levels in mouse epidermis.
Basal levels of cyclic adenosine 3':5'-monophosphate and cyclic guanosine 3':5'-monophosphate were determined in mouse epidermis in vivo after a single topical treatment with the tumor promoter phorbol myristate acetate. No changes in cyclic adenosine 3':5'-monophosphate levels were found from 0 to 72 hr after treatment. A twofold increase in cyclic guanosine 3':5'-monophosphate was found 36 hr after treatment. This increase had subsided by 72 hr. The effect of phorbol myristate acetate on DNA, RNA, and protein synthesis in the epidermis of Ha/ICR mice was also measured.
