KDM1A and colorectal carcinoma: The oncogenic lncRNA HOX antisense intergenic RNA (HOTAIR) binds to polycomb repressive complex 2 (EZH2) and lysine-specific histone demethylase 1A (KDM1A) in the 5′ and 3′ regions and represses the transcription of the homeobox D cluster (HOXD) family genes in breast cancer progression and CRC by acting as a scaffold for histones [37].
