In a different approach, synthesised gold nanorods (GNRa)‐CSP12 are enhanced with chitosan and 12‐mer peptides to improve biodistribution and target leukaemic cells via TfR binding, induce ferroptosis and decrease N6‐methyladenosine (m6A) demethylase activity by disrupting the GSH‐GPX4 axis and altering the Fe2+/Fe3+ ratio in AML cells [77]. The gene discussed is GPX4; the disease is acute myeloid leukemia.
