RESUMEN
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.
