Abstract:
MicroRNAs (miRs) are small, endogenous noncoding RNAs that serve a significant function in various biologic processes, including those involved in cancer. The present study aimed to determine the expression and function of miR-16 in renal cell carcinoma (RCC). Quantitative polymerase chain reaction was used to quantify the expression of miR-16 in 48 paired RCC tissues and adjacent normal tissues. The impact of miR-16 on cell proliferation, migration and apoptosis was analyzed by transfecting miR-16 mature molecules into the renal cancer cell lines 786-O and ACHN. The results indicated that miR-16 was significantly upregulated in RCC tissues (P<0.05). Downregulation of miR-16 resulted in reduced cell proliferation and migration and increased levels of apoptosis, while overexpression of miR-16 resulted in accelerated cellular proliferation and migration, suggesting that miR-16 may function as an oncogene in RCC. The present study demonstrated for the first time, to the best of our knowledge, that miR-16 is upregulated in RCC and acts as an oncogene by inducing cellular proliferation, migration and reducing apoptosis. Further study of miR-16 in RCC may clarify the molecular mechanisms of RCC carcinogenesis and aid in the development of novel biomarkers and therapeutic options.
