We showed that a single DMBA application was sufficient to produce papillomas in Ppp6c-deficient skin and tumor promotion associated with Ppp6c-deficiency is more significant than that seen after repeated applications of TPA. as such, ours was the first report that Ppp6c loss-of-function acts as a tumor promoter in mice. However, it remained unclear whether (1) tumor promotion is specific to DMBA as an initiator or (2) is limited to papilloma or carcinoma formation. To answer these questions, we performed UVB induced carcinogenesis experiment. Following UVB irradiation, mice with Ppp6c-deficient keratinocytes showed a higher incidence of skin basal cell carcinoma than did control mice. UVB-induced tumors in Ppp6c-deficient keratinocytes exhibited a high frequency of both p53- andγH2AX-positive cells, suggestive of DNA damage. Epidemiological and molecular data strongly suggest that Ppp6c is one of the suppressor gene for UVB-induced human skin cancers.
