Webb30 aug. 2014 · Activated BRK–mediated degradation of SMAD4 is associated with the repression of tumor suppressor gene FRK and increased expression of mesenchymal markers, SNAIL, and SLUG. Webb23 okt. 2024 · The tumor-suppressing function of SMAD4 is frequently subverted during mammary tumorigenesis, leading to cancer growth, invasion, and metastasis. A long-standing concept is that SMAD4 is not regulated by phosphorylation but ubiquitination.

Phosphorylation of … 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.
Webb1 jan. 2024 · Smad4, also known as deleted in pancreatic cancer locus 4 (DPC4), was initially found as a tumor suppressor candidate gene in human pancreatic carcinoma in 1996[30]. The term “Smad” was a combination of the smagene of Caenorhabditis elegansand the madgene of Drosophila melanogaster[31].
WebbCCAAT/enhancer-binding protein δ (C/EBPδ) is a transcription factor involved in growth arrest and differentiation, which has consequently been suggested to harbor tumor suppressive activities.
