摘　　要：目的探讨灵芝多糖肽(GLPP)对弥漫性大B细胞淋巴瘤(DLBCL)细胞增殖、迁移和凋亡的影响,及相关作用机制。方法将OCI-LY19细胞分为对照组、GLPP组、si-NC组、si-蛋白质精氨酸甲基转移酶6(PRMT6)组、GLPP+pcDNA3.1-NC组和GLPP+pcDNA3.1-PRMT6组。si-NC组、si-PRMT6组、GLPP+pcDNA3.1-NC组和GLPP+pcDNA3.1-PRMT6组分别转染si-NC、si-PRMT6、pcDNA3.1-NC和pcDNA3.1-PRMT6。待转染完成后,对照组、si-NC组和si-PRMT6组均用RPMI-1640培养基培养,GLPP组、GLPP+pcDNA3.1-NC组和GLPP+pcDNA3.1-PRMT6组均用含20μg·mL^(-1)GLPP的RPMI-1640培养基培养。培养24 h后,检测各组细胞的增殖抑制率、迁移数和凋亡率,用蛋白质印迹法检测细胞中PRMT6蛋白的表达水平。结果si-NC组、si-PRMT6组、GLPP+pcDNA3.1-NC组和GLPP+pcDNA3.1-PRMT6组的细胞增殖抑制率分别为(1.28±0.16)%、(38.61±3.29)%、(52.84±7.74)%和(22.75±3.87)%;对照组、GLPP组、si-NC组、si-PRMT6组、GLPP+pcDNA3.1-NC组和GLPP+pcDNA3.1-PRMT6组的细胞迁移数目分别为(252.65±24.65)、(136.54±16.46)、(231.65±21.24)、(142.76±15.34)、(140.23±9.84)和(192.38±23.38)个,凋亡率分别为(4.36±0.52)%、(28.24±2.36)%、(4.23±0.45)%、(24.54±2.27)%、(28.42±3.85)%和(14.25±2.13)%,PRMT6蛋白相对表达水平分别为1.82±0.21、0.56±0.05、1.78±0.19、0.54±0.05、0.29±0.02和0.32±0.03。对照组的上述指标与GLPP组比较,si-NC组的上述指标与si-PRMT6组比较,GLPP+pcDNA3.1-NC组的上述指标与GLPP+pcDNA3.1-PRMT6组比较,在统计学上差异均有统计学意义(均P<0.05)。结论GLPP可通过下调PRMT6表达,抑制DLBCL细胞增殖、迁移,促进细胞凋亡。Objective To investigate the effect of Ganoderma lucidum polysaccharide peptide(GLPP)on proliferation,migration and apoptosis of diffuse large B cell lymphoma(DLBCL)cells and its mechanism.Methods OCI-LY19 cells were divided into six groups:control,GLPP,si-NC,si-protein arginine methyltransferase 6(PRMT6),GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups.The si-NC,si-PRMT6,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups were transfected withsi-NC,si-PRMT6,pcDNA3.1-NC and pcDNA3.1-PRMT6,respectively.After the transfection was completed,control,si-NC and si-PRMT6 groups were treated with RPMI-1640 medium,while the GLPP,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups were cultured with RPMI-1640 medium containing with 20μg·mL^(-1)GLPP.After administration 24 h,the cell proliferation inhibition rates,mobilityrates and apoptosis rates were detected.The expression levels of PRMT6 protein were measured by Western blotting.Results The cell proliferation inhibition rates of si-NC,si-PRMT6,GLPP+pcDNA3.1-NC and GLPP+pcDNA3.1-PRMT6 groups were(1.28±0.16)%,(38.61±3.29)%,(52.84±7.74)% and(22.75±3.87)%,respectively.The number of cell migrations in the control,GLPP,si-NC,si-PRMT6,GLPP+pcDNA3.1-NC andGLPP+pcDNA3.1-PRMT6 groups was(252.65±24.65),(136.54±16.46),(231.65±21.24),(142.76±15.34),(140.23±9.84)and(192.38±23.38)cells;the apoptosis rates were(4.36±0.52)%,(28.24±2.36)%,(4.23±0.45)%,(24.54±2.27)%,(28.42±3.85)% and(14.25±2.13)%;theexpression levels of PRMT6 protein were 1.82±0.21,0.56±0.05,1.78±0.19,0.54±0.05,0.29±0.02 and0.32±0.03,respectively.The differences of above indexes were statistically significant between control group and GLPP group,between si-NC group and si-PRMT6 group,between GLPP+pcDNA3.1-NC group and GLPP+pcDNA3.1-PRMT6 group(allP<0.05).Conclusion GLPP could inhibit proliferation,migration and promote apoptosis of DLBCL cells by down-regulating PRMT6 expression.
