The effects of antisense oligonucleotide to insulin0like growth factor -Ⅱ(IGFⅡ)to induce apotosis in human ovarian cancer cells were evaluated.Antiproliferation effects of antisense to IGFⅡin ovarian cancer AO cells were determined by ^3H-thymidine incorporation.Apoptosis of the IGFⅡ antisense-treated cells was quantitated by both nuclear condensation and flow cytometry after cells were stained with propidium iodide,IGFⅡ antisense(4.5μM) treatment of 48h maximally inhibited proliferation of AO cells,More than 25% of IGFⅡantisense-treated cells(4.5μM for 24h) had undergone apoptosis,whereas less than 3% of the cells were apoptotic in either IGFⅡ sense-treated cells or untreated cells.Antisense oligonucleotide to IGFⅡ significantly inhibited cell proliferation and induced apoptosis in human ovarian cancer AO cell.These data suggest that IGFII may be a potential target in treatment of ovarian cancer and antisense oligonucleotide to IGFⅡ may serve as a therapeutic approach. 相似文献
