TGF beta (TGF-β) is part of the TGF-β signaling pathway and is highly expressed in a variety of tumors, such as bladder cancer (Zhang et al. 2016), ovarian cancer (Wang et al. 2012), and hepatocellular carcinoma (Peng et al. 2017). This evidence concerns the gene TGFB1 and urinary bladder carcinoma.
