摘要: Background CD147 / extracellular matrix metalloproteinase inducer (EMMPRIN) expressed by tumor cells stimulates peri-tumorous fibroblasts to produce metalloproteinases (MMPs), thus contributing invasion and metastasis. To assess its suitability as a potential therapeutic target, well association with the clinicopathologic features prognosis of patients, expression CD147/EMMPRIN in neoplastic tissues genitourinary system were analyzed. Methods 52 patients renal carcinoma, 58 bladder 101 prostate 17 penis testis carcinoma examined immunostaining on paraffin-embedded specimens using monoclonal antibodies. Then, characteristics patients’ was The RNA interference approach used silence human cell line LNCAP J82. vitro proliferative ability CD147/EMMPRIN-deficient determined 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. Results tissues, but not normal tissues. Positive shown 42 (80.77%) 41 (70.69%) 67 (66.34%) 16 (94.12%) carcinoma. staining significantly associated TNM stages histological subtypes various urinary carcinomas ( P . Conclusion These results may assist defining target method for predicting poor outcome carcinomas.
