Abstract: AIM: To compare the antiproliferative effect and apoptosis-inducing activity by HSPG and HSPG without heparan sulfate chains on human mammary cancer cell MDA-MB-231 in vitro. METHODS: HSPG was isolated and purified, the heparan sulfate chains of HSPG was hydrolyzed by heparitinase1.The changes of two components cell morphology were observed by light microscope, the anti-proliferation of HSPG and HSPG without HS chains was measured by MTT assay, the cell growth curve was drawn and the apoptosis was detected by Annexin V PI double staining and flow cytometry. RESULTS: MCF-7 type HSPG induced the exfoliation and suspension of MDA-MB-231 cells.MTT assay showed that different concentrations of HSPG inhibited MDA-MB-231 cells proliferation in a concentration-dependent manner.There was inhibition effect only in high concentrations of HSPG without HS chains.HSPG induced MDA-MB-231 cells'apoptosis at the early stage, however, 4 mg/mL HSPG without HS chains had some effects on the apoptosis at the early stage. CONCLUSION: HSPG could induce MDA-MB-231 cells' apoptosis at the early stage and distinctly inhibit the growth of MDA-MB-231 cells, the mechanism may be related to HS chains of HSPG.

Key words: heparan sulphate proteoglycan, heparan sulphate chain, MDA-MB-231, MCF-7, apoptosis
