| Popis: | Objective. To investigate the possible development of radix hedysari polysaccharide as an antiglioma drug, we studied the effect of radix hedysari polysaccharide on glioma cells in vitro and the growth of glioma in nude mice and on the phagocytosis of macrophages in nude mice with glioma. Methods. The effect of radix hedysari polysaccharide on the growth of glioma was studied based on U251 cell line in vitro. The effect of radix hedysari polysaccharide on the growth of glioma was studied in vivo. The growth inhibition rate of radix hedysari polysaccharide on U251 cell line was determined by the MTT assay. The cell cycle of U251 was analyzed by flow cytometry. The expression of cytokines in U251 cells and tumor tissues was detected using PCR. The phagocytosis of macrophages in the serum of glioma nude mice was detected by Giemsa staining. TNF-α signaling pathway proteins in the serum of glioma nude mice were detected by ELISA. Results. Radix hedysari polysaccharide inhibited the growth of U251 cells, induced apoptosis in G1 phase by cell cycle arrest, and facilitated apoptosis in glioma mice by regulating cell cycle. Mice injected with radix hedysari polysaccharide showed delayed tumor growth and grew slowly. Radix hedysari polysaccharide enhanced the phagocytosis of macrophages in glioma nude mice. Radix hedysari polysaccharides could inhibit tumor development by regulating the immune function of tumor mice and affecting the TNF-α signaling pathway. Conclusion. Radix hedysari polysaccharide can effectively inhibit the growth of glioma and affect the TNF-α signaling pathway, thus playing an antiglioma role. |
