Abstract:
Objective:To investigate the influence of lncRNA MEG3 on proliferation and autophagy in HCC cells.Methods:Real-time PCR method was used to detect the expression profile of MEG3 in 60 HCC samples and HCC cell lines.CCK-8 assay was performed to investigate the effect of poliferation in HCC cells.Using Western blot and immunofluorescence method to detect the effect of MEG3 on autophagy.Results:The expression of MEG3 was significantly downregulated in HCC tissues and cells(P<0.05).After overexpression of MEG3 in HCC cells,the proliferation of HCC cells was significantly decreased.And the expression of LC3-I to LC3-Ⅱ was reduced(P<0.05).Moreover,the immunofluorescence assay showed overexpression of MEG3 could decrease the LC3 fluorescence points.Conclusion:The expression of MEG3 in liver cancer tissue is lower than normal tissue.In vitro,MEG3 can inhibit the proliferation and autophagy of HCC cells.It is expected to be a potential target for the treatment of HCC.
