LncRNAs that play a role in tumor suppression in endometrial cancer include: FER1L4, GAS5, MEG3, RP11-395G23.3, LA16C −313D11.11, Xist, Linc ROR, MALAT1, HOTAIR, OVAL, SRA, etc., (Guo et al., 2015) However, the mechanism of cuproptosis-associated LncRNAs in endometrial cancer is still unclear. The gene discussed is FER1L4; the disease is endometrial cancer.
