| 中文摘要:目的 研究三种铁死亡诱导剂埃拉斯汀（Era）、柳氮磺胺吡啶（SASP）和青蒿琥酯（Art）与盐酸吉西他滨（hcGEM）单独或联合应用对人胰腺癌PANC-1细胞的抑制作用。方法 采用CCK-8法检测不同浓度的Era、SASP、Art单独或联合hcGEM对PANC-1细胞的增殖抑制作用，并根据联合指数(CI) 判断三种铁死亡诱导剂联合hcGEM对 PANC-1细胞是否具有协同抑制作用。结果 hcGEM与三种铁死亡诱导剂单独或联合应用均能显著抑制PANC-1细胞活性，并且这种抑制作用随着浓度增大而增强。hcGEM-Era 4∶1或1∶4联用组、hcGEM-SASP 1∶400联用组 CI 值小于1。hcGEM-Art 1∶4或1∶16联用组仅在一定浓度范围内CI值小于1。结论 hcGEM与三种铁死亡诱导剂单独或联合应用对PANC-1细胞的增殖抑制作用呈现剂量依赖性。hcGEM与三种铁死亡诱导剂联用能协同抑制PANC-1细胞的增殖。 |

| Abstract:Objective To study the effects of three ferroptosis inducers Erastin (Era), sulfasalazine (SASP) and artesunate (Art) alone or combined with gemcitabine hydrochloride (hcGEM) on the proliferation inhibition of Human pancreatic cell line PANC -1. Methods The CCK-8 method was used to detect the inhibitory effects of different concentrations of Era, SASP and Art alone or combined with hcGEM on the proliferation of PANC-1, and the combination index (CI) was used to judge whether three ferroptosis inducers combined with hcGEM had synergistic inhibitory effect on PANC-1. Results The three ferroptosis inducers and hcGEM alone or in combination could significantly inhibit the activity of PANC-1. The inhibitory effects were enhanced with the concentration increasing. The CI values of hcGEM-Era 4∶1 or 1∶4 combination group and hcGEM-SASP 1∶400 combination group were less than 1.The CI values of hcGEM-Art 1∶4 or 1∶16 combination group were less than 1 only within a certain concentration range. Conclusion The inhibitory effects of the three ferroptosis inducers and hcGEM alone or in combination were dose-dependent. The combination of hcGEM and three ferroptosis inducers could synergistically inhibit the proliferation of PANC-1. |
