Smad4 tumor suppressor

Webb2 feb. 2024 · SMAD4 functions as a tumor suppressor in PCa ( 11, 12 ). In contrast, SMAD3 is overexpressed in advanced PCa ( 13) and reportedly promotes PCa progression ( 13–16 ). Mechanisms of SMAD3 in PCa progression are not well defined. Webbwas shown to suppress the expression of Runx3 and Keap1 tumor suppressors that are commonly downregulated in malignant tumors [17]. However, the role of TrkB in inhibiting the tumor suppressor activity of TGF- has not yet been elucidated.
