Consistent with Era treatment, ETEC infection decreased the expression of GPX4 (Figure 2A) and increased the mRNA levels of ChaC glutathione-specific gamma-glutamylcyclotransferase 1 (CHAC1) (Figure 2B) and solute carrier family 7 member 11 (SLC7A11) (Figure 2C). This evidence concerns the gene CHAC1 and enthesitis-related juvenile idiopathic arthritis.
