摘　　要：目的探讨大黄素抑制胃癌AGS细胞增殖、迁移、侵袭及癌基因YAP1、FOXD1基因表达的可能机制。方法培养胃正常上皮细胞GES-1与胃癌细胞AGS,使用不同浓度大黄素进行干预。通过CCK8实验、划痕实验、Transwell小室实验验证大黄素处理后AGS细胞的生物学表型变化。使用在线软件分析TCGA数据库中糖酵解代谢关键酶HK2和癌基因YAP1、FOXD1在胃癌组织及正常组织中的表达情况。印迹法验证大黄素对AGS中糖酵解代谢关键酶HK2和癌基因YAP1、FOXD1蛋白的影响变化。添加外源性糖酵解代谢产物丙酮酸,增强糖酵解代谢活性,验证癌基因YAP1和FOXD1的相应变化。结果胃正常上皮细胞GES-1与胃癌细胞AGS在不同浓度大黄素干预后,发现GES-1的大黄素半数致死量浓度明显高于AGS(P<0.05)。进一步的CCK8增殖实验、划痕实验、Transwell小室实验结果均发现大黄素可以明显抑制AGS的增殖、迁移、侵袭等肿瘤生物学能力(P<0.05)。TCGA生物信息数据库分析发现糖酵解途径关键酶HK2和癌基因YAP1、FOXD1在胃癌组织中的表达明显高于胃正常组织的表达(P<0.05)。大黄素可以明显抑制糖酵解关键酶HK2和癌基因YAP1、FOXD1的蛋白表达(P<0.05)。补充外源性糖酵解代谢产物丙酮酸后,癌基因YAP1、FOXD1的蛋白表达显著升高(P<0.05)。结论大黄素对胃癌AGS细胞有显著的药理抑制作用,可以明显抑制其肿瘤生物学表型。大黄素在显著抑制糖酵解代谢关键酶HK2的同时,也显著抑制癌基因YAP1、FOXD1的蛋白表达。当添加外源性丙酮酸增强糖酵解代谢通路后,癌基因YAP1、FOXD1的蛋白表达显著升高。以上提示YAP1、FOXD1和糖酵解代谢的密切相关性,大黄素可能通过抑制胃癌AGS细胞糖酵解代谢,抑制癌基因YAP1和FOXD1。Objective To explore the possible mechanism of emodin in inhibiting proliferation,migration,and invasion of AGS cells and in suppressing the expressions of YAP1 and FOXD1.Methods Normal gastric cell GES-1 and gastric cancer cell AGS were cultured with different concentrations of emodin.CCK8 test,scratch test and Transwell assay were used to verify changes in the biological phenotype of AGS cells.TCGA database was applied to analyze expressions of HK2,YAP1 and FOXD1 in gastric cancer tissues and normal gastric tissues.Western blotting method was used to detect the impacts of emodin on HK2,YAP1 and FOXD1 proteins in AGS cells.Exogenous pyruvic acid was added to verify the changes in YAP1 and FOXD1.Results The IC50 of emodin was significantly higher in GES-1 cells than in AGS cells(P<0.05).CCK8 proliferation test,scratch test,and Transwell assay showed that emodin significantly inhibited the biological abilities of AGS(P<0.05 for comparisons).Analysis on the TCGA bioinformatics database found that the expression of key enzymes HK2 in the glycolysis pathway and oncogenes YAP1 and FOXD1 was significantly higher in gastric cancer tissues than in normal gastric tissues(P<0.05 for comparisons).Emodin significantly inhibited the protein expressions of key glycolytic enzymes HK2 and oncogenes YAP1 and FOXD1(P<0.05 for comparisons).With supplement of exogenous glycolytic metabolite pyruvate,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased(P<0.05 for comparisons).Conclusions Emodin has a significant pharmacological inhibitory effect on gastric cancer AGS cells,markedly suppressing their biological phenotype.Emodin not only significantly inhibits the key enzyme HK2 in glycolysis metabolism,but also the protein expressions of oncogenes YAP1 and FOXD1.With the addition of exogenous pyruvate to enhance the glycolytic metabolic pathway,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased.The above results suggest a close association of YAP1 and FOXD1 with glycolytic metabolism.Emo
