Several proteins or agents [e.g., DAZAP1 (Wang et al., 2021), MT-1G (Sun et al., 2021), BCAT2 (Wang et al., 2021), QSOX1 (Sun et al., 2021), and Solasonine (Jin et al., 2020), Table 1] exerted significant impacts on ferroptosis in HCC cells. This evidence concerns the gene BCAT2 and hepatocellular carcinoma.
