Zastosowanie

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.[1] It was used to study the role of TGF-β signaling in modulation of extracellular matrix[2] and myoblast differentiation.[3]

Działania biochem./fizjol.

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.[4][5][6] It does not inhibit kinases that are activated in response to serum or stress such as ERK, p38 or JNK.[5]

Molecular pharmacology, 62(1), 58-64 (2002-06-18)
Transforming growth factor beta1 (TGF-beta1) is a potent fibrotic factor responsible for the synthesis of extracellular matrix. TGF-beta1 acts through the TGF-beta type I and type II receptors to activate intracellular mediators, such as Smad proteins, the p38 mitogen-activated protein
A Smad3 and TTF-1/NKX2-1 complex regulates Smad4-independent gene expression.

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

Neoplasia (New York, N.Y.), 15(2), 204-217 (2013-02-27)
In epithelial tumors, the platelet-derived growth factor receptor B (PDGFRB) is mainly expressed by stromal cells of mesenchymal origin. Tumor cells may also acquire PDGFRB expression following epithelial-to-mesenchymal transition (EMT), which occurs during metastasis formation. Little is known about PDGFRB

  2. How long can I store the reconstituted compound in the freezer -20 degrees? i have one that was aliquoted 4 years ago. Is it still ok to use it ?

    1 answer
    1. It is recommended, following reconstitution, to aliquot and freeze -20°C. The stock solutions are stable for up to 6 months at -20°C. The quality of solutions stored frozen for extended periods has not been evaluated. The end user would have to determine suitability. Any color change, cloudiness, or particulate matter present upon thawing would be a visual indicator of degradation.
