In intact canonical TGFβ signaling, the binding of a TGFβ to the TGFβ type II receptor enables the formation of a heteromeric complex between TGFβ type I and type II receptors. The type I receptor is phosphorylated by the type II receptor serine/threonine kinase. The activated type I ...
nucleus, but signaling causes the Smads to accumulate predominantly in the nucleus where they bind DNA and other transcriptional machinery to regulate the expression of target genes. Abnormalities of the TGF-beta receptors and SMADs have been detected in various tumors, including colorectal cancers and...

Malignant cells can circumvent the suppressive effects ofTGF-betaeither through inactivation of core components of the pathway, such as TGF-beta receptors (Figure 1, Path 1), or by downstream alterations that disable just the tumor-suppressive arm of this pathway (Figure 1, Path 2). If the ...
serine/threonine kinase receptors. Canonical TGF-β signaling is mediated by Smadproteins, which transduce the TGF-β signal from the cell surface into thenucleus to regulate transcription. Upon TGF-β binding and receptor activation,the TGF-β receptor phosphorylates Smad2 and Smad3. SARA (Smad ...

The receptors for TGFs are quite complicated and made up of many different subunits. These receptors’ generic structure includes interactions between type I and type II receptors. The serine/threonine kinase domain is present in both types of receptors, which are transmembrane proteins. Ligands......
Only few tumours showed expression of TGF-β receptors (27% or 84 of 309 for type1; 5% or 14 of 295 for type 2). The rate of receptor expression was not linked to histological grade, regional or distant metastasis or survival. In the majority of tumours (nuclear or cytoplasmatic) expre...
The aim of this immunohistochemical study was to determine whether there is any altered expression of TGF-β isoforms or its receptors in tissue from patients with drug-induced GO (DIGO; n=10) and hereditary gingival fibromatosis (n=10) when compared to non-overgrowth tissue (n-10). Compared...
