摘　　要：目的探讨通关藤注射液和通关藤提取液对人骨肉瘤细胞增殖、迁移、侵袭和凋亡的影响及潜在机制。方法体外培养人骨肉瘤细胞MNNG/HOS、Saos-2和人骨髓间充质干细胞(BMSC),分别予通关藤注射液或通关藤提取液(40、60、80 mg/mL)处理,CCK-8实验和平板克隆实验检测细胞增殖能力,划痕实验和Transwell实验检测细胞迁移和侵袭能力,Hoechst33342染色和Annexin-V/PI双染实验检测细胞凋亡情况,RT-qPCR检测细胞Bax、Bcl-2、胱天蛋白酶-3(Caspase-3)mRNA表达,Western blot检测细胞Bax、Bcl-2、Caspase-3、Janus激酶1(JAK1)、p-JAK1、信号转导和转录激活因子3(STAT3)、p-STAT3、基质金属蛋白酶(MMP)9蛋白表达。结果与对照组比较,不同浓度通关藤注射液和提取液均能显著降低MNNG/HOS和Saos-2细胞存活率,抑制细胞克隆形成、迁移和侵袭,诱导细胞凋亡(P<0.05,P<0.01),促进细胞BaxmRNA和蛋白表达,抑制Bcl-2mRNA和蛋白表达,上调Caspase-3mRNA和CleavedCaspase-3蛋白表达。通关藤注射液可显著下调Saos-2细胞p-JAK1、p-STAT3、MMP9蛋白表达(P<0.05,P<0.01)。结论通关藤注射液和提取液均可显著抑制人骨肉瘤细胞MNNG/HOS和Saos-2增殖、迁移和侵袭,诱导其凋亡,二者抗肿瘤作用无明显差异,其机制可能与抑制JAK1/STAT3信号通路激活有关。Objective To investigate the effects and potential mechanisms of Marsdeniae Tenacissimae Caulis(Tongguanteng)injection and extract in human osteosarcoma cells proliferation,migration,invasion,and apoptosis.Methods MNNG/HOS,Saos-2 osteosarcoma cells,and normal bone marrow mesenchymal stem cells(BMSC)were cultured in vitro.Cells were incubated with different concentrations of Tongguanteng injection and Tongguanteng extract(40,60,80 mg/mL).Cell proliferation was evaluated by CCK-8 assay and plate colony formation assay.Cell migration and invasion were evaluated by scratch assay and Transwell assay.Cell apoptosis was evaluated by Hoechst33342 staining and Annexin-V/PI double staining assay.Bax,Bcl-2 and Caspase-3 mRNA expression were detected using RT-qPCR.The protein expressions of JAK1,p-JAK1,STAT3,p-STAT3 and MMP9 were detected by Western blot.Results Compared with the control group,both Tongguanteng injection and extract significantly decreased the survival rate of MNNG/HOS and Saos-2 cells,inhibited cell clone formation,migration,and invasion,induced cell apoptosis(P<0.05,P<0.01),promoted Bax mRNA and protein expression,inhibited Bcl-2 mRNA and protein expression,and up-regulated Caspase-3 mRNA and Cleaved Caspase-3 protein expression.Tongguanteng injection could significantly down-regulate the expressions of p-JAK1,p-STAT3 and MMP9 protein expression in Saos-2 cells(P<0.05,P<0.01).Conclusion Both Tongguanteng injection and Tongguanteng extract can significantly inhibit proliferation,migration and invasion of human osteosarcoma MNNG/HOS and Saos-2 cells,and induce apoptosis,with no significant difference in anti-tumor effect.The mechanism may be related to the inhibition of the activation of JAK1/STAT3 signaling pathway.
