The first model utilised\ud dimethylbenz[a]anthracene initiation and 12-O-tetradecanoylphorbol 13-acetate (TPA) promotion in the FVB/N mouse, and the second TPA promotion of the Tg.Ac mouse, which is endogenously initiated by virtue of an activated Ha-ras transgene. Comparison of gene expression profiles\ud across the two models identified genes whose altered expression was associated with papilloma formation rather than TPA induced proliferation and differentiation. DMBA suppressed TPA induced differentiation which allowed identification of those genes associated more specifically with differentiation rather than proliferation. EASE (Expression Analysis Systemic Explorer)\ud indicated a correlation between muscle associated genes and skin differentiation while genes involved with protein biosynthesis were strongly correlated with proliferation. For verification the\ud altered expression of selected genes were confirmed by RT-PCR; Carbonic anhydrase 2,\ud Thioredoxin 1 and Glutathione S-transferase omega 1 associated with papilloma formation and Enolase 3, Cystatin β and Filaggrin associated with TPA induced proliferation and differentiation. \ud In situ analysis located the papillomas Glutathione S-transferase omega 1 expression to the proliferating areas of the papillomas. Thus we have identified profiles of differential gene expression associated with the tumourgenesis and promotion stages for skin carcinogenesis in\ud the mouse
