Oncogenic miR-23a-5p is associated with cellular function in RCC

In recent years, accumulating evidence has demonstrated that microRNAs (miRs, miRNAs) may serve an important role in the occurrence and development of tumors. miR‑23a‑5p has been confirmed as an oncogene in numerous diseases through gene chip analysis. However, as the most common type of renal tumor, the expression and function of miR‑23a‑5p in renal cell carcinoma (RCC) remains unclear. In the present study, reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis, and Cell Counting Kit‑8 (CCK‑8), wound scratch, Transwell, MTT and flow cytometry assays were performed to investigate the role of miR‑23a‑5p in RCC. The expression of miR‑23a‑5p in RCC tissue samples was significantly higher compared with that in normal tissue samples (P
