CARM1 and breast cancer: Ellagic acid (TBBD) (35) and pyrazole-containing derivatives have been elucidated as inhibitors of coactivator-associated arginine methyltransferase (CARM1, also known as PRMT4), responsible for catalyzing H3R17me2 and H3R26me2, modifying non-histone proteins (e.g., p300/CBP (CREB-binding protein) and SRC-3 (Steroid receptor coactivator-3)), co-activating several transcription factors (e.g., steroid receptors) and being involved in prostate and breast cancer progression [117,119,120,121].
