Abstract
To observe the inhibitory effect of Hypoxia inducible factor-1 antisense oligonuclecotide on growth of human hepatocellular carcinoma cells and gene expression of HIF-1, in order to seek a new gene therapy for hepatocellular carcinoma. Six Hypoxia inducible factor-1 antisense oligonuclecotides with various concentrations (0.2 micromol/l, 0.4 micromol/l, and 0.8 micromol/l) were transformed into HepG2 cells by lipofectamine reagent. 72 h after transfection, MTS assay was used to detect cellular proliferation. In addition, Hypoxia inducible factor-1 antisense oligonuclecotide2 with various concentrations (0.2, 0.4, 0.8, and 1.0 micromol/l) were transformed into HepG2 cells. About 48 h after transfection, reverse transcription-polymerase chain reaction assay and Western Blot assay were employed to detect the expression of Hypoxia inducible factor-1 gene and the synthesis of Hypoxia inducible factor-1 protein respectively. HepG2 cell growth was inhibited by 6 Hypoxia inducible factor-1 antisense oligonuclecotides at various concentrations. Among them, Hypoxia inducible factor-1 antisense oligonuclecotide2 showed the most effective inhibition ability (P < 0.01), the inhibitory rate was 89.66% at the concentration of 1.0 micromol/l. ...Continue Reading
