Article Title: Disulfiram/Copper Induces Antitumor Activity against Both Nasopharyngeal Cancer Cells and Cancer-Associated Fibroblasts through ROS/MAPK and Ferroptosis Pathways

doi: 10.3390/cancers12010138

Figure Lengend Snippet: DSF/Cu inhibits nasopharyngeal carcinoma cells via the ferroptosis pathway. ( A ) Western blot analysis for the expression of p53-related proteins in 5-8F treated with DSF/Cu (1 μM/1 μM); the p53 inhibitor Pifithrin-α (20 μM) was pretreated for 12 h. Data are shown as means ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001, n = 3. ( B , C ) RT-qPCR analysis of Ptgs2 and SAT1 mRNA levels in 5-8F. Data are shown as means ± SD. * p < 0.05, *** p < 0.001 vs. control group, n = 3. ( D ) The expression of SAT1 was detected by Western blotting in 5-8F, after cultured with DSF/Cu (1 μM/1 μM). Data are shown as means ± SD. *** p < 0.001, n = 3. ( E ) RT-qPCR analysis of ALOX15 mRNA levels in 5-8F. Data are shown as means ± SD. ** p < 0.01, *** p < 0.001 vs. control group, n = 3. ( F ) Lipid ROS production in 5-8F treated with DSF/Cu (1 μM/1 μM) for 6 h was assessed by flow cytometry using C11-BODIPY. NAC was pretreated for 12 h. Data are shown as means ± SD. *** p < 0.001, n = 3. ( G ) The percentage of viable 5-8F cells after being treated with DSF/Cu (1 μM/1 μM) for 24 h. Inhibitors were pretreated for 12 h. DMSO solvent was used as a control. Data are shown as means ± SD. *** p < 0.001 vs. DSF/Cu group (the second group), n = 3.
