The effects of Dkk3 on tumor growth and carcinogenesis of colorectal cancer. PCR primers were designed (A) and subjected to PCR of tail and stomach DNA (B) with the same color for the corresponding primers and products. Expression of Dkk3, N-cadherin, and E-cadherin was confirmed by real-time PCR (C) and Western blot (D). Immunohistochemistry was employed to observe the maker proteins’ expression in the intestinal adenoma of target villin-cre/Dkk3 knockout mice induced by sodium desoxycholate (E). *p < 0.05, compared with the transfectant or knockout mice. WT, wild-type mice; VD, villin-cre +; Dkk3 -/-.
