It’s a SMAD/SMAD World
DPC4/SMAD4 mutations are associated with aggressive pancreatic cancer. In this issue of Cell, Whittle et al. demonstrate that Runx3 expression combined with Dpc4/Smad4 status can predict the metastatic propensity of pancreatic tumors, providing valuable guidance for personalized therapy for patients with pancreatic cancer.
متن کاملSmad about elastin regulation.
Elastin is crucial to pulmonary function, yet it appears in the pulmonary vasculature and interstitium late in gestation in large mammals and postnatally in rodents (1). Deletion of the ELN gene in mice produces obstructive arterial disease (2, 3) and disrupts terminal airway branching as well as alveogenesis (4); moreover, several forms of elastic tissue disease collectively known as cutis lax...
متن کاملRegulation of Smad Activity
binding by the ternary Smad–FAST complex. Smad3 can bers are a group of secreted polypeptides that regulate replace Smad2 in this complex and at the Mix.2 element a diverse array of developmental and biological pro-can activate transcription (Yeo et al., 1999), whereas at the cesses. Disruption of the ligands or of components of goosecoid promoter Smad3 blocks activation (Labbé et their signali...
متن کاملSmad signalling network.
Dimeric ligands of the transforming growth factor β (TGF-β) superfamily bind with high affinity to type II and type I receptor serine/threonine kinases on the cell surface and induce hetero-tetrameric receptor complexes. In such complexes, constitutively auto-phosphorylated type II receptors (green) trans-phosphorylate (arrows) the type I receptor (blue) GS domain. Activated receptors recruit a...
متن کاملA Smad Transcriptional Corepressor
Following TGFbeta receptor-mediated phosphorylation and association with Smad4, Smad2 moves into the nucleus, binds to target promoters in association with DNA-binding cofactors, and recruits coactivators such as p300/CBP to activate transcription. We identified the homeodomain protein TGIF as a Smad2-binding protein and a repressor of transcription. A TGFbeta-activated Smad complex can recruit...
