The expression of ferroptosis markers, such as acyl-CoA synthetase long chain family member 4 (ACSL4) (Yuan et al., 2016b; Figure 5G) and prostaglandin-endoperoxide synthase 2 (PTGS2) (Yang et al., 2014; Figure 5H) in tumor extracts was reduced in the STING1KD or MFN1/2KD group. The gene discussed is PTGS2; the disease is neoplasm.
