SIRT1对肝癌细胞耐药敏感性的影响
Effect of SIRT1 on drug resistance of hepatocellular carcinoma cells
摘要
Abstract
Objective To build a short-hairpin RNA (shRNA)interference lentiviral vector of silent information regulator(sir)-like protein 1 (Sirtuin 1,SIRT1 )gene and to explore its effect on proliferation and drug resistance in hepatocellular carcinoma(HCC)cells.Methods The SIRI1 target specific oligonucleotide sequence was designed and connected to pSicoR-green fluorescent protein(GFP)vector digested by the HpaⅠ and XhoⅠ.Then,293T cells were packaged to produce the lentivirus and transfected with liver cancer cells.qRT-PCR assays further indicated that SIRT1 gene was stably knocked down in HCC cells.The effect on cell proliferation was detected by foci formation assay and CCK8 assay.In addition,drug resistance experiments and qRT-PCR were used to detect the effect on resistance of liver cancer cells when the SIRT1 gene was knocked down.Results The result of qRT-PCR demonstrated that the lentivirus shRNA vector of SIRT1 gene was constructed and could suppress the expression level of SIRT1.The proliferation and drug resistance genes of HCC cells were inhibited and drug sensitivity was enhanced.Conclusion SIRT1 gene represses the drug resistance of HCC cells.关键词
