“In a two-stage mouse epidermal carcinogenesis experiment using 7,12-dimethylbenz(a)anthracene as the initiator, glycocholic acid as the 1st stage promoter, and mezerein as the 2nd stage promoter, palm carotene inhibited the promoting activity of glycocholic acid.”
“ Palm carotene suppressed mouse epidermal ornithine decarboxylase activity induced by glycocholic acid.”
