Abstract

This study investigated the expression of microRNA-210 (miR-210) in tissue and serum of renal carcinoma patients and its effect on renal carcinoma cell proliferation, apoptosis, and invasion. Thirty-two renal carcinoma patients in our hospital were selected as the study group and 32 people receiving a physical examination were selected as the control group. miR-210 expression in the serum of renal carcinoma patients and in healthy subjects was quantified by real-time polymerase chain reaction. After miR-210 overexpression and inhibition in ACHN cells in human renal carcinoma, ACHN cell proliferation, apoptosis, and invasion were detected by CCK-8, flow cytometry, and a transwell invasion assay. The expression of miR-210 was significantly higher in renal carcinoma than in corresponding paracarcinoma tissues (P < 0.001). The expression of miR-210 was significantly higher in the serum of renal carcinoma than in the control group (P < 0.001). ACHN cell proliferation and invasion were significantly increased and apoptosis was significantly decreased (P < 0.05) when miR-210 was overexpressed. ACHN cell proliferation and invasion were significantly decreased and apoptosis was significantly increased (P < 0.05) when miR-210 was inhibited. In conclusion, miR-210 was highly expressed in tissues and serum of renal carcinoma patients. miR-210 could promote the proliferation and invasion of renal carcinoma cells and inhibit the apoptosis of renal cell carcinoma cells.
