In breast cancer cells the lncRNA SRA (Steroid Receptor RNA Activator), originally identified in human B-lymphocyte [80], plays a scaffolding role bringing together the repressive complex LSD1-HP1γ-HDAC1/2-CoREST-KDM5B, referred as HP1 γ-LSD1 complex [81,82]. Here, KDM1A is linked to breast cancer.
