ABSTRACT
Objective To explore renal clear cell carcinoma ( CCRCC) expression and significance of CD146 mR-NA in tumor tissue of patients with. Methods ELISA method for quantitative detection was used for CD146 protein and real-time PCR technique for the detection of CCRCC in 102 ( CCRCC) expression in tumor tissue of patients with CD146 mRNA, and 51 cases of renal patients with non tumor tissues as control. Results Found metastasis in patients with CCRCC, the CD146 protein concentration was statistically significant compared with the control group (F=52.1, P<0.01),the average expression of CD146 mRNA value (0.043 8±0.002 4) was significantly high-er than that of in situ CCRCC patients (0.038 2±0.001 1, P= 0.018) and control group (0.034 4±0.001 0, P=0.001 ) . Conclusion Pathological grading and lymph node up regulation of CD146 mRNA expression in renal cell carcinoma and metastasis, is expected to become a new index, evaluation of malignant degree of CCRCC me-tastasis and prognosis, and provide a reliable basis for the intervention of clinical treatment.
