OBJECTIVE To explore the expressions of the p53 isoforms in renal cell carcinoma (RCC) tissue and their relationship with the tumor invasion and metastasis. METHODS Collected 22 pairs of renal cell carcinoma specimens and the adjacent nonneoplastic tissue in Baotou and analyzed the mRNA expressions of △133p53, △133p53β, △133p53γ, P53β, P53γ by RT-PCR. RESULTS The expressions of △133p53, △133p53β, △133p53γ between RCC and the adjacent nonneoplastic tissue showed no significant differences (P ﹥ 0.05) ; The p5...
