Selaginella trichoclada-derived robustaflavone A induces ferroptosis by downregulating the expressions of acyl-CoA synthetase long-chain family member 4 (ACSL4), ACSL5, STEAP3, lysophosphatidylcholine acyltransferase (LPCAT3), and autophagy-related 7 (ATG7) genes in breast cancer cells (Table 1) [43]. This evidence concerns the gene ATG7 and breast cancer.
