许多体内实验认为 TGF- β1对肿瘤的生长有促进作用 ,肿瘤组织细胞中 PCNA指数常作为肿瘤增殖程度的指标。我们通过免疫组化方法对 43例肾癌TGF-β1和 PCNA进行检测 ,从蛋白水平探讨TGF-β1和 PCNA在肾癌组织中的表达情况 ,并探讨其与肿瘤侵袭力之间的相关性。1 材料与方法 ?
Many in vivo experiments suggest that TGF-β1 promotes the growth of the tumor, and the PCNA index in tumor cells often serves as an indicator of the degree of tumor proliferation. We detected the expression of TGF-β1 and PCNA in 43 cases of renal cell carcinoma by immunohistochemistry, and explored the expression of TGF-β1 and PCNA in renal cell carcinoma from the protein level, and explored the correlation between TGF-β1 and invasiveness of tumor. 1 materials and methods?
