Abstract:

 OBJECTIVE: To investigate the effects of Leek seed polysaccharide on the proliferation and apoptosis of human esophagus cancer cell EC9706. METHODS:Flow cytometry,Hoechst33258 staining,transmission electron microscope and DNA gel electrophoresis were used. RESULTS:Proliferation of EC9706 cells was significantly inhibited by Leek seed polysaccharide at the dose of 40 μg/mL(P<0.05). Moreover,after 48 hour of treatment by Leek seed polysaccharide,obvious characteristic features of apoptosis and DNA ladder were also induced. CONCLUSION: Leek seed polysaccharide could inhibit EC9706 cell proliferation and induce its apoptosis.

Key words:  Leek seed polysaccharide, human esophagus cancer cell EC9706, proliferation, apoptosis
