May 2003 in “Development” The study demonstrated that Myc activation in mouse epidermis led to the depletion of the epidermal stem cell compartment by altering adhesive interactions with the local microenvironment. This was evidenced by the transcriptional analysis of over 10,000 genes, revealing that Myc activation induced genes related to RNA and protein synthesis, cell proliferation, and differentiation, while downregulating over 40% of genes associated with cell adhesion and cytoskeleton proteins. These changes impaired keratinocyte adhesion, motility, and wound healing, correlating with decreased expression of extracellular matrix proteins and integrins, and reduced formation of hemidesmosomes and actomyosin cytoskeleton assembly. Consequently, Myc activation prompted stem cell exit and differentiation into sebocytes and interfollicular epidermis at the expense of hair lineages, due to impaired keratinocyte migration necessary for hair differentiation.

January 1992 in “Carcinogenesis” The study investigated the effects of multiple exposures to 12-O-tetradecanoylphorbol-13-acetate (TPA), mezerein, and ethyl phenylpropriolate (EPP) on murine epidermal cells, focusing on the induction of ornithine decarboxylase (ODC) activity. While single applications of these agents caused similar hyperplasia and ODC induction, multiple treatments revealed significant differences in ODC activity, with TPA and mezerein inducing more than EPP. Immunocytochemical analysis showed distinct patterns of ODC-positive cells, with TPA prominently affecting perifollicular cells, mezerein affecting both interfollicular and perifollicular areas, and EPP affecting only interfollicular cells. Flow cytometry identified three keratinocyte subpopulations, with TPA causing the expansion of an intermediate-sized subpopulation not seen with EPP or mezerein. The findings suggested that TPA, a potent tumor promoter, selectively expanded a keratinocyte subpopulation hyperinducible for ODC, potentially important for neoplastic transformation, while mezerein and EPP were less effective in this regard.
