摘要 目的:观察芒果苷对人淋巴瘤Raji细胞增殖、侵袭能力及T淋巴瘤侵袭转移诱导因子1(Tiam1)表达的影响,以探讨芒果苷抗淋巴瘤的初步作用机制。方法:用MTT法检测芒果苷对人淋巴瘤Raji细胞增殖的影响,用Transwell侵袭实验检测芒果苷对Raji细胞侵袭能力的抑制作用,用RT-PCR法检测芒果苷作用Raji细胞后对Tiam1的mRNA表达的影响。结果:MTT法发现,不同浓度的芒果苷分别与Raji细胞共同孵育72 h后,芒果苷对Raji细胞增殖抑制作用具有明显的剂量和时间依赖性。Transwell侵袭实验发现,用不同药物浓度的芒果苷作用Raji细胞24 h后,可抑制Raji细胞穿透Transwell小室,随着药物浓度的增加其穿透滤膜的细胞数明显具有剂量依赖性。分别用不同浓度的芒果苷作用Raji细胞24 h后,发现Tiam1的mRNA表达量明显减少,且呈明显的量效关系。结论:芒果苷能抑制人淋巴瘤Raji细胞的增殖和侵袭,其机制可能与同细胞侵袭有密切关系的Tiam1的mRNA表达下调有关。
