Application
SB-431542 was used to study the correlation of platelet-derived growth factor receptor B expression and TGF-β pathway activation in colorectal tumor cells. It was used to study the role of TGF-β signaling in modulation of extracellular matrix and myoblast differentiation.
Biochem/physiol Actions
Potent and selective inhibitor of transforming growth factor-β superfamily type I activin receptor-like kinase (ALK) receptors.
SB-431542 inhibits the TGF-β-mediated activation of SMAD proteins, expression of collagen and fibronectin, cell proliferation and cell motility. It does not inhibit kinases that are activated in response to serum or stress such as ERK, p38 or JNK.

Transforming growth factor-beta (TGF-beta) is a multifunctional cytokine that promotes malignant glioma invasion, angiogenesis, and immunosuppression. Antisense oligonucleotide suppression of TGF-beta(2) ligand expression has shown promise in preclinical and clinical studies but at least two ligands mediate the effects of

Inappropriate activation of developmental pathways is a well-recognized tumor-promoting mechanism. Here we show that overexpression of the homeoprotein Six1, normally a developmentally restricted transcriptional regulator, increases TGF-beta signaling in human breast cancer cells and induces an epithelial-mesenchymal transition (EMT) that
