[Effects of Compound Aconitum Polysaccharide on Glycosylation of Tumor Cells].

ABSTRACT

Objective To observe inducing or inhibiting effects of Chinese medicine (CM) poly- saccharides on glycoprotein chain synthetized different glycosyltransferases, thus disclosing targets of CM polysaccharides and its mechanisms. Methods In vivo anti-tumor effects of CM polysaccharides were observed using the inhibiting rate of tumor growth by dividing different Aconitum containing groups. Effects of CM polysaccharides on liver cancer cell SK-HEP-1 glycosyltransferase and tumor related gene expressions were observed. Meanwhile, changes of polylactosamine expression were detected using flow cytometry (FCM) with polylactosamine specific biotin labeling lectin. Results Compared with the model group, the average tumor weight was significantly lower in each medication group (P <0. 01). Compared with the adriamycin group, no significant difference in average tumor weight of the three compound groups (P>0. 05). The expression level of polylactosamine was reduced after adding Aconitum polysac- charide; and CM compound polysaccharides respectively. Conclusions Polysaccharide compound showed similar anti-tumor effect as that of adriamycin. Besides, polylactosamine expression level was reduced in the three compound groups along with increased prepared Aconitum polysaccharide, with more obvious anti-tumor effects shown.
