SNAI1 and posterior cortical atrophy: Several transcriptional regulators of EMT in PCa, including zinc finger protein SNAI1 (SNAIL), zinc finger protein SNAI2 (SLUG), ZEB1/2, and twist-related protein 1 (TWIST) [108,109], are under the control of diverse growth factor signaling mechanisms, such as transforming growth factor-β (TGF-β) [109].
