摘要: [摘要]目的:通过RT-PCR等方法对肾癌P16基因mRNA进行了检测研究,以探讨抑癌基因P16纯合性缺失与肾癌发生发展的关系。方法:应用分子生物学RT-PCR等方法检测24例肾细胞癌和10例对照组(非癌症肾组织)P16基因mRNA的表达情况。结果:在24例肾癌中,P16基因表达缺失14例(58.3%),中等阳性表达6例(25%),弱阳性表达4例(16.7%)。而对照组10例正常肾组织均呈强阳性表达(100%)。本实验研究还发现P16基因与肾癌病理分级无相关性,与临床分期有显著相关(P<0.05)。结论:抑癌基因P16在肾细胞癌的生长,浸润,和转移过程中可能起重要作用,对肾脏恶性肿瘤的诊断、治疗和预后的判定,可能具有潜在的临床价值。

Abstract: Abstract: Objective: To study the relationship between the homozygous deletion of P16 tumor suppressor gene and the occurrence and development of kidney cancer,as pathogenesis basis of renal cell carcinoma. In this study, we detected P16 gene mRNA of renal cell carcinoma by RT-PCR method. METHODS: The molecular biology methods such as RT-PCR were applicated to detected the P16mRNA expression of 24 cases of renal cell carcinoma and 10 control group (non-cancerous kidney tissue). Results: In 24 cases of renal cell carcinoma, P16 gene deletion in 14 cases (58.3%), intermediate expression in 6 cases (25%), weakly positive in 4 cases (16.7%). The control group (10 normal kidney tissue) were strongly positive (100%). P16 gene change in renal cell carcinoma is not associated with tumor grade and clinical staging. Conclusion: P16 tumor suppressor gene may play an important role in renal cell carcinoma growth, invasion and metastasis, may have potential clinical value in the diagnosis of kidney cancer and to determine prognosis.
