LncRNA URHC promotes cell proliferation by regulating a miR-5007-3p/DNAJB9 axis in hepatocellular carcinoma

Abstract Background: To investigate the underlying mechanisms of lncRNA URHC in HCC. Methods: RT-qPCR, FISH staining, EdU, colony formation, and tumor xenografts experiments were used to identify localized and biological effects of URHC on HCC cells in vitro and in vivo. The Bioinformatics analysis, Dual- luciferase reporter assay, and rescue experiments revealed the potential mechanism of URHC. Results: We found that URHC was mainly localized in the cytoplasm. URHC silencing may inhibit the HCC cells proliferation. And URHC positively regulated the level of DNAJB9 by sponging miR-5007-3p. Conclusion: Together, our study elucidated the role of URHC as a miRNA sponge in HCC, and shed new light on lncRNA-directed diagnostics and therapeutics in HCC.
