Abstract

Long non-coding RNAs (lncRNAs) take various biological effects in clear cell renal cell carcinoma (ccRCC) mostly through sponging with microRNAs (miRNAs). lncRNA MIR4435-2HG is found to promote tumour progression in gastric cancer, glioblastoma and hepatocellular carcinoma. However, the role of lncRNA MIR4435-2HG in ccRCC progression remains unknown. The purpose of this research was to investigate the potential molecular mechanism of lncRNA MIR4435-2HG regarding the regulation of ccRCC initiation and progression. In this study, we found the up-regulation of MIR4435-2HG in ccRCC tissues and cell lines. Functionally, overexpression of MIR4435-2HG promoted the proliferation as well as the metastasis in ccRCC cell lines, whereas knockdown of MIR4435-2HG inhibited the above changes. Then, bioinformatic analysis and luciferase reporter assays confirmed the negative regulation effect of MIR4435-2HG on miR-513a-5p. And further investigations showed that KLF6, which collected from the intersection of databases, was the potential conjugated mRNAs of miR-513a-5p. Finally, the rescue experiments revealed the relation among MIR4435-2HG and KLF6, which showed that KLF6 could reverse the promoting effect of MIR4435-2HG on ccRCC in vitro and in vivo. Therefore, our findings provided insight into the mechanisms of MIR4435-2HG in ccRCC and revealed an alternative target for the clinical diagnosis and treatment of ccRCC.
