Tumor promoter 12-0-tetradecanoyl-phorbol-13-acetate elevates serum progesterone levels

Journal Article · · Biochem. Biophys. Res. Commun.; (United States)
The phorbol ester 12-0-tetradecanoyl-13-acetate (TPA), the most potent promoter of two-stage carcinogenesis in mouse skin, simulates some of the early effects of several carcinogens in immature chicks. Actinomycin D, ethionine, thioacetamide (non-mutagenic in the Ames Salmonella test) and kepone are known to increase serum progesterone concentrations and induce synthesis of ovalbumin in chicks. Intraperitoneal administration of TPA to chicks caused a 5- to 7-fold elevation of serum progesterone levels and induced ovalbumin synthesis. Phorbol ester, 4..cap alpha..-phorbol-12, 13-didecanoate, which is inactive as a mouse skin tumor promoter, did not increase serum progesterone levels nor did it induce ovalbumin synthesis.
