Lnc-HUR1 is an HBV-related long non-coding RNA, which can promote the proliferation of hepatoma cells and the occurrence and development of liver cancer. In this study we explored the effect of lnc-HUR1 on the apoptosis of hepatocellular carcinoma cells by taking the approach of immunoblotting, quantitative real time PCR, luciferase reporter assay, chromatin immunoprecipitation (ChIP) and flow cytometry. We found that overexpression of lnc-HUR1 significantly reduced the activity of caspase3/7 and the cleavage of PARP-1, while knocking down of lnc-HUR1 significantly increased the activity of caspase3/7 and promoted the cleavage of PARP-1 in HepG2 cells treated with TGF-β, pentafluorouracil or staurosporine. Consistently, the data from Annexin-V/PI staining showed that overexpression of lnc-HUR1 inhibited apoptosis, while knockdown of lnc-HUR1 promoted apoptosis. Moreover, overexpression of lnc-HUR1 up-regulated the apoptosis inhibitor Bcl-2 and down-regulated the pro-apoptotic factor BAX at both RNA and protein levels. In the CCL4-induced acute liver injury mice model, the expression of Bcl-2 in the liver tissue of lnc-HUR1 transgenic mice was higher than that of the control mice. The data from ChIP assay indicated that lnc-HUR1 reduced the enrichment of p53 on Bcl-2 and BAX promoters. All these results indicated that lnc-HUR1 inhibited the apoptosis by promoting the expression of apoptosis inhibitor Bcl-2 and inhibiting the expression of apoptosis promoting factor BAX. Further studies showed that lnc-HUR1 regulated the transcription of Bcl-2 and BAX in HCT116 cells, but had no effect on the expression of Bcl-2 and BAX in HCT116 p53^−/− cells, indicating that lnc-HUR1 regulates the transcription of Bcl-2 and BAX dependent upon the activity of p53. In conclusion, HBV upregulated lnc-HUR1 can inhibit the apoptosis of hepatoma cells. Lnc-HUR1 inhibits apoptosis by inhibiting the transcriptional activity of p53. These results suggest that lnc-HUR1 plays an important role in the occurrence and development of HBV-related hepatocellular carcinoma.
