Abstract

MicroRNAs (miRs) have emerged as critical modulators of tumor initiation and progression in numerous types of human cancer, including clear cell renal cell carcinoma (ccRCC), which is the most common subtype of renal cell carcinoma. Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a newly characterized oncoprotein and its overexpression has been reported to promote cellular epithelial‑mesenchymal transition and the tumor progression of ccRCC. The present study examined the effects of miR‑218 on CIP2A expression in ccRCC cells. The results demonstrated that the expression level of miR‑218 was lower in ccRCC tissues compared with that in adjacent non‑tumor renal tissues. In addition, it was identified that miR‑128 could directly bind to the 3'‑untranslated region of CIP2A. Furthermore, a negative correlation between the expression levels of miR‑218 and CIP2A was detected in ccRCC. Additionally, the down­regulation of CIP2A or overexpression of miR‑218 in ccRCC cells was revealed to inhibit cell proliferation and migration. In summary, these data suggest that miR‑218 serves a role in the regulation of CIP2A and elucidate its consequences on tumor progression, tumor cell proliferation and migration. These results indicate that miR‑218 may exhibit potential as a molecular target for the treatment of ccRCC.
