Background: Long non-coding RNAs (lncRNAs) are essential for tumorigenesis and progression of diverse cancers. This study aims to investigate the roles of lncRNAs on renal carcinoma.
Methods: The expression of lncRNA HIF1A-AS2 in clear cell renal cell carcinoma (ccRCC) and adjacent non-cancer tissues was identified by quantitative real-time PCR (qRT-PCR). Investigations were performed on biological function of lncRNA HIF1A-AS2 on cell proliferation, cell cycle, apoptosis and invasion of ccRCC by overexpression and knockdown experiments. Further, luciferase reporter assay and Western blot were constructed to explore molecular mechanisms underlying the function of lncRNA HIF1A-AS2.
Results: HIF1A-AS2 was highly expressed in kidney cancer tissues and ccRCC cells. Interference of HIF1A-AS2 in vivo hindered cell proliferation, invasion and migration while accelerated cell apoptosis. Overexpression of HIF1A-AS2 presented an opposite effect that repressed the expression of miR-130a-5p, and miR-130a-5p inhibited the expression of HIF1A-AS2. Additionally, rescue experiments exhibited that oncogenic function of HIF1A-AS2 was partially dependent on the suppression of miR-130a-5p.
Conclusion: Our results indicated a critical role for the HIF1A-AS2-miR-130a-5p axis in renal carcinoma progression, which may act as a promising diagnostic biomarker and a pivotal therapeutic target for renal carcinoma cures.
