DUOX1 knockdown reversed DOX-induced inflammation and abnormal protein expression. The secretion of IL-1β (A) and IL- 18 (B) in the cell supernatant was detected by ELISA. C LDH activity was detected by biochemical method. D Western blot was used to detect the expression of pyroptosis indexes active caspase-1, pro-caspase-1, NLRP3, and GSDMD-N. **p < 0.01 vs. control; ^^p < 0.01 vs. shNC + DOX (2 µmol/L). The blots were cut prior to hybridisation with antibodies during immunoblotting experiments
