January 1980 in “Carcinogenesis” This study found that TPA was significantly more effective than mezerein in inducing dark basal keratinocytes in mouse skin, which may be important in early tumor promotion stages.

October 2003 in “PubMed” In this study, PKCepsilon transgenic mice showed increased TNFalpha shedding during skin tumor promotion, which may contribute to the development of metastatic squamous cell carcinoma.

January 2001 in “Archives of Biochemistry and Biophysics” This study found that TPA induces apoptosis in pig renal epithelial cells by affecting cell cycle proteins, and activated ras can prevent this process.
37 citations
,
January 1986 in “Carcinogenesis” This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

January 1992 in “Carcinogenesis” This study suggests that chronic treatment with TPA in mouse skin selectively expands a keratinocyte subpopulation hyperinducible for ODC, which may be a key target for neoplastic transformation.
