Transforming growth factor signal transduction
Transforming growth factor beta1 (TGF1) is the prototypic member of a large family of structurally related pleiotropic-secreted cytokines that play a pivotal role in the control of differentiation, proliferation, and state of activation of many different cell types including immune cells. TGFfamily members have potent immunosuppressor activities in vitro and in vivo. These cytokines trigger the...
متن کاملTransforming growth factor-beta1 suppresses hepatocellular carcinoma proliferation via activation of Hippo signaling
In this study, we examined the expression of core proteins of the Hippo signaling pathway in hepatocellular carcinoma (HCC) cells treated with transforming growth factor-β 1(TGF-β1) and investigated the relationship between TGF-β1 and the Hippo signaling pathway, in order to better understand their roles in HCC and their potential implications for cancer therapy. We prove that the Hippo signali...
متن کاملSmad4 and transforming growth factor beta1 expression in patients with squamous cell carcinoma of the esophagus.
PURPOSE The members of the Smad family play key rolesin regulating gene expression in the transforming growth factor (TGF)-beta1 signaling pathways. Activation of Smads causes their translocation from the cytoplasm to the nucleus, where they function as transcription factors. The present study analyzed the expression and clinicopathological significance of Smad4 and TGF-beta1 in squamous cell c...
متن کاملTransforming growth factor-beta1-induced Smad signaling, cell-cycle arrest and apoptosis in hepatoma cells.
Transforming growth factor-beta1 (TGFbeta) is involved in the regulation of liver cell proliferation and apoptosis, and escape of hepatoma cells from the growth restraining signals of TGFbeta has been suggested to contribute to tumor development. TGFbeta modulates gene transcription by receptor-mediated activation of Smad proteins which act as transcription factors. TGFbeta-mediated primary sig...
متن کاملTargeted disruption of Smad3 reveals an essential role in transforming growth factor beta-mediated signal transduction.
The Smads are a family of nine related proteins which function as signaling intermediates for the transforming growth factor beta (TGF-beta) superfamily of ligands. To discern the in vivo functions of one of these Smads, Smad3, we generated mice harboring a targeted disruption of this gene. Smad3 null mice, although smaller than wild-type littermates, are viable, survive to adulthood, and exhib...
