Abstract

MicroRNAs (miRNAs/miRs) serve an important role in the regulation of carcinogenic pathways. RCC is the most prevalent kidney cancer that occurs in adults. miRNAs have gained increasing attention due to their association with RCC tumorigenesis, serving as biomarkers for early detection and progression monitoring, and as potential targets for molecular therapy. Upregulation of miRNA‑142‑3p has been previously identified in RCC tissues by microarray profile, however, its expression and function in RCC have not yet been validated. In the present study, quantitative polymerase chain reaction was performed to quantify the relative expression of miR‑142‑3p in 53 paired RCC and adjacent normal tissues. Furthermore, wound healing, 3‑(4,5‑dimethylthiazol‑2‑yl)‑2,5‑diphenyltetrazolium bromide and flow cytometry assays were performed to analyze the impacts of miR‑142‑3p on cellular migration, proliferation and apoptosis. The results demonstrated that miR‑142‑3p was significantly upregulated in RCC tissues compared with adjacent normal tissues. Downregulation of miR‑142‑3p, induced by chemically synthesized miR‑142‑3p inhibitor, significantly suppressed cell migration and proliferation, and promoted cell apoptosis in 786‑O and ACHN cells, supporting the theory that miR‑142‑3p may function as an oncogene in RCC. The potential clinical significance of miR‑142‑3p, as a biomarker and therapeutic target, provides rationale for further investigation into the miR-142-3p-mediated molecular pathway and how it is associated with RCC development.
