目的 研究石见穿多糖对结肠癌SW620细胞上皮间质转化(Epithelial-mesenchymal transition,EMT)的影响,探讨石见穿多糖抑制结肠癌侵袭转移的作用机制。方法 采用不同浓度石见穿多糖对SW620细胞进行干预,干预时间分别为12小时和24小时;CCK-8法检测各组细胞的增殖,并选择后续实验的药物浓度和时间;细胞划痕和Transwell迁移实验来检测各组细胞的迁移能力;Transwell侵袭实验检测各组细胞的侵袭力;Western blot和qRT-PCR方法检测EMT相关蛋白E-cadherin、Vimentin及其mRNA,以及转录因子ZEB1、ZEB2、Twist1及其mRNA的表达。结果 与对照组比较,石见穿多糖能够抑制SW620细胞的增殖,且浓度越高、干预时间越长,抑制作用越强,且呈浓度和时间依赖性。因此,在后续实验中,选择0。25 mg·mL-1、1 mg·mL-1、2 mg·mL-1、3 mg·mL-1作为干预浓度,选择24 h作为干预时间。与对照组比较,石见穿多糖能够抑制SW620细胞的迁移和侵袭,且浓度越高,抑制作用越强,呈浓度依赖性;与对照组比较,石见穿多糖能够上调E-cadherin及其mRNA的表达,且浓度越高,表达水平越高,呈浓度依赖性;同时下调Vimentin、ZEB1、ZEB2、Twist1及其mRNA的表达,且浓度越高,表达水平越低,呈浓度依赖性。结论 石见穿多糖能够抑制SW620细胞的增殖、迁移和侵袭,其机制可能与上调E-cadherin的表达,下调Vimentin、ZEB1、ZEB2和Twist1的表达,从而抑制EMT过程有关。
Effects of Salvia Chinensis Benth Polysaccharides on Epithelial Interstitial Transformation of Colon Cancer SW620 Cells
Objective To investigate the effects of Salvia chinensis Benth polysaccharides on epithelial mesenchymal transition(EMT)in colon cancer SW620 cells,and to explore the mechanism of Salvia chinensis Benth polysaccharides in inhibiting invasion and metastasis of colon cancer.Methods Different concentrations of Salvia chinensis Benth polysaccharides were used to intervene SW620 cells for 12 and 24 hours,respectively.The proliferation of each group of cells was detected using the CCK-8 method,and the drug concentration and time for subsequent experiments were selected;Cell scratch and Transwell migration experiments were used to detect the migration ability of each group of cells;Transwell invasion experiment was used to detect the invasiveness of cells in each group;Western blot and qRT-PCR assays were used to detect the expression of EMT related proteins E-cadherin,Vimentin and their mRNA,as well as transcription factors ZEB1,ZEB2,Twist1 and their mRNA.Results Compared with the control group,Salvia chinensis Benth polysaccharides can inhibit the proliferation of SW620 cells,and the higher the concentration and the longer the intervention time,the stronger the inhibitory effect in a concentration and time dependent manner.Therefore,in subsequent experiments,0.25 mg·mL-1、1 mg·mL-1、2 mg·mL-1 and 3 mg·mL-1 were selected as intervention concentrations and 24 h as intervention time.Compared with the control group,Salvia chinensis Benth polysaccharides can inhibit the migration and invasion of SW620 cells,and the higher the concentration,the stronger the inhibitory effect,in a concentration dependent manner;Compared with the control group,Salvia chinensis Benth polysaccharides can upregulate the expression of E-cadherin and its mRNA,and the higher the concentration,the higher the expression level,in a concentration dependent manner;Simultaneously downregulated the expression of Vimentin,ZEB1,ZEB2,Twist1 and their mRNA and the higher the concentration,the lower the expression level,in a concentration dependent manner.Conclusion Salvia chinensis Benth polysaccharides can inhibit the proliferation,migration,and invasion of SW620 cells,and its mechanism may be related to upregulating the expression of E-cadherin and downregulating the expression of Vimentin,ZEB1,ZEB2,and Twist1,thereby inhibiting the EMT process.
