TGF-beta/Smad

Transforming growth factor beta

Transforming growth factor-beta (TGF-β) is a member of a superfamily of pleiotropic proteins that regulate multiple cellular processes such as growth, development and differentiation. The intracellular effectors of TGF-beta signalling, the Smad proteins, are activated by receptors and translocate into the nucleus, where they regulate transcription. Although this pathway is inherently simple, combinatorial interactions in the heteromeric receptor and Smad complexes, receptor-interacting and Smad-interacting proteins, and cooperation with sequence-specific transcription factors allow substantial versatility and diversification of TGF-beta family responses. Other signalling pathways further regulate Smad activation and function.

In addition, TGF-beta receptors activate Smad-independent pathways that not only regulate Smad signalling, but also allow Smad-independent TGF-beta responses. Aberrant TGF-β signaling is associated with a variety of diseases, such as fibrosis, cardiovascular disease and cancer. Hence, the TGF-β signaling pathway is recognized as a potential drug target.

    Fusaric acid (Standard)
    Inhibitor
    Fusaric acid (Standard) is the analytical standard of Fusaric acid (HY-128483). This product is intended for research and analytical applications. Fusaric acid is an orally active multi-pathway inhibitor with the activity of inducing oxidative stress and apoptosis. Fusaric acid can chelate divalent metal cations, damage mitochondrial membrane structure, and activate apoptosis-related proteases such as Caspase-3/7, -8, and -9. Fusaric acid also regulates Bax/Bcl-2 protein, inhibits fibrosis-related signaling pathways such as NF-κB, TGF-β1/SMADs, and PI3K/AKT/mTOR, and reduces collagen deposition. Fusaric acid is also a dopamine β-hydroxylase inhibitor, which reduces endogenous levels of norepinephrine and epinephrine in the brain, heart, spleen, and adrenal glands. Fusaric acid can play a role in myocardial fibrosis and improve cardiac hypertrophy in heart disease, and can also be used in the study of esophageal cancer and liver cancer.
