To gain insights into the molecular mechanism of auraptene on HCC ferroptosis, we treated HCCLM3 and HLE cells with auraptene, and the Western blot showed that auraptene significantly decreases the expression of SLC7A11 instead of GPX4, ACSL4 and FSP1 (Figure 5A,B). The gene discussed is GPX4; the disease is hepatocellular carcinoma.
