Increased propensity of skin carcinogenesis in Hipk2+/− and Hipk2−/− mutant mice. (A) Two-stage skin carcinogenesis paradigm induces more tumors in Hipk2+/− and Hipk2−/− mutants compared with WT littermates (P < 0.0001). (B) Incubation time for tumor formation is much shorter in Hipk2+/− and Hipk2−/− mutants (P = 0.0151 for WT and Hipk2+/−; P = 0.004 for WT and Hipk2−/−). (C) A higher percentage of the skin tumors in Hipk2+/− and Hipk2−/− mutants develop into carcinoma (P < 0.0001). Data in B and C are presented by using the Kaplan–Meier method, and statistical analyses are performed by using Student's t test.
