Besides, sh-RACGAP1 group showed highest level of 4-HNE (Fig. 8I), a ferroptosis marker indicating cytotoxic lipid peroxidation, and highest iron content (Fig. 8J) in tumor tissue than control and sh-NC groups, while such changes were partly blocked by CPT1A overexpression. The gene discussed is RACGAP1; the disease is neoplasm.
