N normal phenotype
homeostasis/metabolism
• treatment with a skin carcinogenesis (DMBA/TPA) protocol results in a small but significant decrease in proliferating cell numbers compared to similarly treated control mice
• decrease in the incidence of papillomas in a skin carcinogenesis assay

neoplasm
• decrease in the incidence of papillomas in a skin carcinogenesis assay
• papillomas that do form following a skin carcinogenesis (DMBA/TPA) protocol contain more apoptotic cells

integument
• increase in the number of apoptotic cells in the epidermis in the presence or absence of TPA treatment
• enhanced keratinocyte apoptosis
