To explore the inhibitory effect of integrin-linked kinase antisense oligonucleotide (ILK-ASODN) on cell proliferation in human ovarian cancer cell line (HO8910).We transfected ILK-ASODN into HO8910 to block ILK gene expression, measured the expression levels of integrin-linked kinase (ILK) mRNA by RT-PCR and ILK protein by western-blotting; the inhibiting effects of the transfection on HO8910 proliferation, the cell cycles, and cell apoptosis were assessed by water soluble tetrazolium-1 (WST-1) and flow cytometry (FCM).After transfection of ILK-ASODN, the expression levels of ILK mRNA decreased significantly in groups D, E, F being 0.307 +/- 0.011, 0.198 +/- 0.008, 0, respectively, when compared with those of the two control groups of A and B (P0.05). The expression levels of ILK protein of the groups D, E and F decreased significantly also, being 26.3 +/- 0.8, 20.6 +/- 0.4 and 0, respectively. HO8910 cell proliferation was inhibited significantly, and the rates of apoptosis of the groups D, E and F increased significantly, being 7.31%, 8.84% and 11.27% respectively. The cell population increased in G0/G1 phase of the groups D, E and F, being 49.25%, 56.28% and 67.61% respectively, significantly different in comparison with those of groups of A and B (P0.01).Transfection of ILK-ASODN into human ovarian cancer line inhibited cancer cell proliferation significantly. |
