Webb1 feb. 2010 · Smad signaling is required to maintain epigenetic silencing during breast cancer progression Breast cancer progression is associated with aberrant DNA methylation and expression of genes that control the epithelial-mesenchymal transition (EMT), a critical step in malignant conversion. Role of Smad in cancer Defects in Smad signaling can result in TGF-B resistance, causing dysregulation of cell growth. Deregulation of TGF-B signaling has been implicated in many cancer types, including pancreatic, colon, breast, lung, and prostate cancer. Smad4 is most commonly mutated in human … Visa mer Smads (or SMADs) comprise a family of structurally similar proteins that are the main signal transducers for receptors of the transforming growth factor beta (TGF-B) superfamily, which are critically important for … Visa mer Before Smads were discovered, it was unclear what downstream effectors were responsible for transducing TGF-B signals. Smads were first discovered in Drosophila, in which they are known as mothers against dpp (Mad), through a genetic screen for dominant … Visa mer R/Co-Smads TGF-B ligands bind receptors consisting of type 1 and type 2 serine/threonine kinases, which serve to propagate the signal intracellularly. Ligand … Visa mer The R-Smads consist of Smad1, Smad2, Smad3, Smad5 and Smad8/9, and are involved in direct signaling from the TGF-B receptor. Smad4 is … Visa mer Smads are roughly between 400 and 500 amino acids long, and consist of two globular regions at the amino and carboxy termini, connected by … Visa mer The components of the TGF-beta pathway and in particular, the R-Smads, Co-Smad and I-Smads, are represented in the genome of all metazoans sequenced to date. The level of … Visa mer In adult cells, TGF-β inhibits cell cycle progression, stopping cells from making the G1/S phase transition. This phenomenon is present in the epithelial cells of many organs, and is regulated in part by the Smad signaling pathway. The precise mechanism … Visa mer
