lncRNA H19 can act as a competitive endogenous RNA to bind to miR-19b-3p, thereby enhancing the transcriptional activity of its endogenous target ferritin heavy chain 1(FTH1), and CUL plays a role in promoting ferroptosis by down-regulating lncRNA H19 in lung cancer cells [211]. The gene discussed is H19; the disease is lung carcinoma.
