Melatonin coordinates lncRNA to inhibit breast cancer development, and FK506-binding protein (FKBP3) and lnc010561 act as competing endogenous RNAs (ceRNAs) for the tumor suppressor mir-30, which regulates breast cancer development because of the significant downregulation of FKBP3 by melatonin (Liu P. et al., 2020). The gene discussed is FKBP3; the disease is neoplasm.
