TGFB INHIBITORS AND USE THEREOFDisclosed herein are novel inhibitors of TGFβ1 activation with durable inhibitory effects. Methods directed to the selection of a suitable TGFβ inhibitor for various disease conditions and patient populations are also provided....
To evaluate the in vivo contribution of TGF-β signaling in lung epithelium to the development of allergic disease and lung cancer, we generated a transgenic mouse model with Smad7, an intracellular inhibitor of TGF-β signaling, constitutively expressed in mouse airway Clara cells using a mouse ...
SB525334是一种有效的,选择性的TGFβ receptor I (ALK5)抑制剂,IC50为14.3 nM,作用于ALK4比作用于ALK5效果低4倍,可抑制ALK2, 3,和6活性。A potent ATP-competitive inhibitor against receptor TbR-I/ALK5. SB525334 is a potent and selective inhibitor of TGFβ receptor I (ALK5) with IC50 of 14.3...
而Smad3 mRNA则有增加. 而Smad3与HSC中的TGFb反应元件相连接, 刺激aⅠ型胶原与Ⅰ型纤溶酶原激活物抑制因子(plasminogen activator inhibitor-1, PAI-1)基因转录, 与Smad2不同的是, 这种作用不受Smad7过表达的抑制. 我们研究发现, 肝纤维化大鼠经培哚普利治疗后, 在TGFb1重要的下游信号通道蛋白Smad中, 对TGF...
转化生长因子-B(transforming growth factor-B,TGF-B)是属于一组新近发现的调节细胞生长和分化的TGF-B超家族.这一家族除TGF-B外,还有活化素(activins)、抑制素(inhibins)、缪勒氏管抑制质(Mullerian inhibitor substance,MIS)和骨形成蛋白(bone morpho-genetic proteins,BMPs).TGF-B的命名是根据这种细胞因子能使...
The indicated cells were lysed in radioimmunoprecipitation assay buffer (RIPA, Beyotime, China) supplemented with protease and phosphatase inhibitor cocktail (Epizyme, China). Bicinchoninic acid assay (BCA, Biosharp, China) was used to detect protein concentration. The proteins were separated using 10%...
We have previously shown that blocking MEK1/2 is partially effective in shrinking mutant Kras-driven lung cancer48. Interestingly, we found that SB525334 synergized with an FDA approved MEK1/2 inhibitor, Trametinib, to control H23 cell growth (Fig.7a). Similar synergy was observed in PC-9 ...

Importantly, we observed that treatment with 50 mM of the TGFb receptor inhibitor, SB431542, significantly suppressed the BEC differentiation of YAP 5SA over- expressing hepatoblasts (Fig. 4e) and slightly restored the expression levels of Hnf4a and Cyp7a1 in hepatocytes over- expressing the ...
