Clear cell renal cell carcinoma (ccRCC), the most common subtype of renal cell
carcinoma, can easily invade local tissues and metastasize, and is resistant to
currently available treatments. Recent studies profiling microRNA expression in
ccRCC have suggested miR-30a-5p may be deregulated in these cancer cells. To
determine its role and mechanism of action in ccRCC, miR-30-5p expression levels
were quantified and functions were analyzed using in vitro and in vivo
experiments and bioinformatics. A decrease in miR-30a-5p expression was
frequently noted in ccRCC cells and tissues. Importantly, low miR-30a-5p levels
were significantly associated with a poor ccRCC patient prognosis. Stable
overexpression of miR-30a-5p in 769-P cells was sufficient to prevent cellular
proliferation and invasion in vitro and in vivo. Upon further examination, it was
found that miR-30a-5p directly targeted the 3'-UTR of ZEB2 and suppressed ccRCC
cell epithelial-mesenchymal transition. In addition, miR-30a-5p may be
downregulated by the long non-coding RNA DLEU2. Taken together, these data reveal
an important role for miR-30a-5p in the regulation of ccRCC proliferation and
invasion, and indicate the potential for miR-30a-5p in applications furthering
ccRCC prognostics and therapeutics.
