Its expression in tumor of pT3 and pT4 is obviously higher than pT1 and pT2 (P<0.01). That is to say, there was an overexpression of β-catenin protein in RCC and its level was related to the tumor stage, but the expression of β-catenin mRNA had no difference between tumor tissue and normal tissue.Conclusion β-catenin may be related to the occurrence and progress of RCC.展开更多
