• Clear‐cell renal‐cell carcinoma (ccRCC) is the most common renal cell carcinoma (RCC), representing 75%‐80% of the cases of RCC, and characterized by a high recurrence rate and poor prognosis. miR‐452 acts as a tumor promoter in several tumors, including ccRCC. The purpose of this study was to determine the role of miR‐452 in ccRCC. miR‐452 and SOX7 messenger RNA and protein levels were calculated by quantitative reverse transcription polymerase chain reaction and Western blot analysis. MTT and Transwell assays were utilized to measure proliferative and invasive abilities. The Kaplan‐Meier method was used to evaluate the association between the expression of miR‐452 or SOX7 and the overall survival of ccRCC patients. Our results showed that miR‐452 was overexpressed in ccRCC tissues and cells, and upregulation of miR‐452 predicted a poor 5‐year survival in ccRCC patients. In contrast, expression of SOX7 was low and downregulation of SOX7 predicted poor prognosis in ccRCC. In addition, miR‐452 promoted cell proliferation, invasion, and the EMT, while SOX7 reversed the function of miR‐452 on cell proliferation and invasion in 786‐O cells. In conclusion, miR‐452 was shown to inhibit cell proliferation, invasion, and the EMT through SOX7 in ccRCC, and the newly identified miR‐452/SOX7 axis provided novel insight into the pathogenesis of ccRCC. 1. The present study is the first to demonstrate that miR‐452 participate in the carcinogenesis of clear‐cell renal‐cell carcinoma. 2. miR‐452 promoted the development of clear‐cell renal‐cell carcinoma by targeting SOX7. 3. The regulatory mechanism in miR‐452/SOX7 axis is firstly proposed in this study.
