摘要:

目的 明确安五脂素(ANW)对胃癌细胞恶性生物学行为的调控作用,并探讨其潜在分子机制。 方法 采用CCK-8法、EdU染色及克隆形成实验评估ANW对人胃癌细胞系HGC-27和SGC-7901活力与增殖能力的影响;构建裸鼠移植瘤模型,结合Ki-67免疫组化染色验证ANW对胃癌细胞体内增殖的作用。通过流式细胞术检测细胞周期分布,Western blotting检测周期相关蛋白(Cyclin D1、CDK2、P53)表达;采用Annexin V-FITC/PI双染流式细胞术检测细胞凋亡率,TUNEL法标记凋亡细胞,Western blotting检测凋亡相关蛋白(Cleaved Caspase-3、Bcl-2、Bax)表达。利用Transwell检测细胞迁移与侵袭能力,Western blotting检测基质金属蛋白酶(MMP-2、MMP-9)表达。通过qPCR和Western blotting检测上皮-间质转化(EMT)标志分子(Vimentin、E-cadherin、Snail、Slug)的mRNA及蛋白表达水平;Western blotting分析JAK1/STAT3信号通路关键蛋白(p-JAK1、JAK1、p-STAT3、STAT3)的磷酸化水平,联合RO8191通路激活及JAK1 siRNA敲低实验,验证JAK1/STAT3通路是ANW抗肿瘤作用的关键介导通路。 结果 ANW以浓度依赖方式显著抑制HGC-27和SGC-7901增殖及克隆形成能力(P<0.05),并诱导细胞周期阻滞于G1期,伴随Cyclin D1、CDK2蛋白表达下调及P53蛋白表达降低(P<0.05)。体内实验进一步证实,ANW可抑制裸鼠移植瘤生长,降低瘤体组织中Ki-67阳性表达率(P<0.05)。ANW可显著促进胃癌细胞凋亡,表现为凋亡率升高,抗凋亡蛋白Bcl-2表达下调,促凋亡蛋白Cleaved Caspase-3及Bax表达上调(P<0.05)。此外,ANW能显著抑制胃癌细胞迁移与侵袭能力,同时下调MMP-2、MMP-9蛋白表达(P<0.05);并可抑制EMT进程,具体表现为间质标志物Vimentin及转录因子Snail、Slug表达降低,上皮标志物E-cadherin表达升高(P<0.05)。分子机制层面,ANW可显著抑制JAK1及STAT3的磷酸化水平(P<0.05);JAK1/STAT激活剂RO8191可逆转ANW对胃癌细胞恶性行为的抑制作用,siRNA沉默JAK1既可模拟ANW的抗肿瘤效应,又能与之协同;ANW在裸鼠移植瘤中抑制EMT,而RO8191则削弱其体内抑瘤作用。 结论 安五脂素可通过抑制JAK1/STAT3信号通路的活化,进而阻滞细胞周期进程、促进细胞凋亡、抑制EMT及MMPs介导的侵袭迁移能力,最终发挥抗胃癌作用。本研究为ANW作为胃癌潜在治疗药物的开发提供了实验依据。

Abstract:

Methods To evaluate the inhibitory effect of anwulignan (ANW) on malignant biological behaviors of gastric cancer cells and explore its underlying molecular mechanism. Methods The inhibitory effect of ANW on viability and proliferation of gastric cancer HGC-27 and SGC-7901 cells were evaluated using CCK-8 assay, EdU staining and colony formation assay. In a nude mouse model bearing gastric cancer xenografts, the effect of ANW on tumor cell proliferation was examined using immunohistochemistry for Ki-67. The changes in cell cycle, apoptosis, migration, invasion, and expressions of MMPs and epithelial-mesenchymal transition (EMT) markers following ANW treatment were detected using flow cytometry, TUNEL staining, Western blotting, Transwell assay, and qPCR. The role of the JAK1/STAT3 signaling pathway in mediating the anti-tumor activity of ANW was validated by detecting JAK1/STAT3 phosphorylation, pathway activation and siRNA-mediated JAK1 knockdown experiments. Results In HGC-27 and SGC-7901 cells, ANW dose-dependently suppressed cell proliferation and colony formation, induced G1 cell cycle arrest, and downregulated the expressions of cyclin D1/CDK2 and P53. ANW treatment significantly inhibited tumor growth and decreased Ki-67 positivity in the mouse xenografts. ANW effectively promoted cell apoptosis, suppressed Bcl-2 expression, upregulated cleaved caspase-3 and Bax expressions, inhibited migration and invasion, lowered MMP-2/MMP-9 expressions, and blocked EMT progression in gastric cancer cells. Mechanistically, ANW significantly inhibited JAK1/STAT3 phosphorylation, while the JAK1/STAT3 activator RO8191 reversed the anti-tumor effect of ANW; JAK1 knockdown mimicked and enhanced the inhibitory effect of ANW on gastric cancer cells. ANW significantly inhibited EMT in the mouse xenografts, and this effect was attenuated by RO8191 treatment. Conclusion ANW inhibits malignant phenotype of gastric cancer cells by inhibiting the activation of the JAK1/STAT3 signaling pathway, thereby inducing cell cycle arrest, promoting apoptosis, and suppressing EMT and MMP-mediated invasion and migration, suggesting the potential of ANW as a therapeutic agent for gastric cancer.
