中文摘要:
      目的:研究灵芝多糖对单核巨噬白血病细胞THP-1和RAW264.7 的肿瘤生物学活性的影响。方法:用1、50 和100 μg/ml的 灵芝多糖和脂多糖(LPS)刺激THP-1 和RAW264.7 细胞,CCK-8 法测定巨噬细胞的增殖活力、流式细胞仪检测细胞的凋亡活性、Q-PCR检测细胞因子TNF-α、IL-1、IL-6 和IL-12 基因、相关凋亡信号通路基因TRADD、TNFSF10、TNFRSR10b、NFκBI、Caspase10 和Caspase 3基因的mRNA 表达水平。结果:灵芝多糖可以呈反浓度依赖性地刺激两种细胞的增殖,在50 和100 μg/ml 浓度下 可引起细胞凋亡,凋亡信号基因TNFRSR10b 和NFκBI的mRNA 水平在24h 升高了53%和48%;在1~100 μg/ml 浓度下可上调细胞因子TNF-α、IL-1、IL-6和IL-12 细胞因子mRNA 的表达水平。结论:灵芝多糖对白血病细胞株具有双重作用,在低浓度下促 进细胞增殖,而在高剂量时诱导细胞凋亡,均可上调免疫相关细胞因子的表达。
英文摘要:
      Objective:To study the effects of Ganoderma lucidum polysaccharides (GLP) on tumor biology of the monocyte- macrophage THP-1 and RAW264.7.Methods:After THP-1 and Raw264.7 cells were stimulated with different concentrations of GLP and LPS, the proliferation and apoptosis activity of cells were analyzed by CCK-8 kits and flow cytometry. RT-PCR was used to detect expression of cytokines of macrophages,such as TNF-α, IL-1, IL-6 and IL-12, and Q-PCR was used to detect the gene expression levels in apoptosis signaling pathway.Results:GLP could promote proliferation of THP-1 and RAW264.7 cells in an inverse dose-dependent , and up-regulate expression of cytokines secretion at all concentrations. And also GLP could elevate expression of apoptosis related genes TNFRSR10b and NFκBI.Conclusion:GLP played a dual role on leukemia cell line, that is it increased expression of cytokines and promoted cells proliferation at lower concentration, while at high doses caused cells apoptosis.
