Hox transcript antisense intergenic RNA (HOTAIR), located within the Homeobox C (HOXC) gene cluster on chromosome 12, is a 2158 nucleotide lncRNA that regulates epigenetic gene silencing by functioning as a scaffold for polycomb repressive complex 2 (PRC2) and lysine-specific histone demethylase 1 (LSD1) and functions as an oncogene in many cancers [7,15]. This evidence concerns the gene KDM1A and cancer.
