BACKGROUND Transforming growth factor beta 1 (TGF-β1) is an inhibitor of muscle cell differentiation that is associated with fibrosis, poor regeneration and poor function in some diseases of muscle. When neutralizing antibodies to TGF-β1 or the angiotensin II inhibitor losartan were used to reduce TGF-β1 signaling, muscle morphology and function were restored in mouse models of Marfan Syndrome ...
The present study employed a zinc-finger nuclease strategy to create heterozygous knockout (KO) rats for the transforming growth factor-β1 (Tgfb1) gene on the Dahl SS/Jr genetic background (TGF-β1(+/-) Dahl S). Intercrossing TGF-β1(+/-) rats did not produce any homozygous KO rats (66.4% +/-, 33.6% +/+), indicating that the mutation is embryonic lethal. Six-week-old wild-type (WT) littermates an...
Objective: To compare Transforming growth factor-β1 (TGF-β1) expression in various L-PRF concentrations on the hDPSC differentiation process. Material and Methods: cell cultures were subjected to serum starvation by reducing FBS levels culture media. Lysate PRF was obtained from gel, which then incubated at 4°C for 24 h. The supernatant dried, transferred a 2-ml Eppendorf tube, stored −20°C. ev...
Purpose: To investigate the differential expressions of transforming growth factor-β1 (TGF-β1), hypoxia inductive factor-1 (HIF-1), vascular endothelial factor (VEGF), α-smooth muscle protein (α-SMA) and E-cadherin in renal tissues neonatal rat model hydronephrosis.Methods: The rats (90) were randomly divided into sham group group. further two subgroups: week 1 12 after relief obstruction, with...
Glomerular matrix accumulation is a hallmark of diabetic renal disease. Serine/threonine kinase PKC-β1 mediates glucose-induced Akt S473 phosphorylation, RhoA activation, and transforming growth factor (TGF)-β1 upregulation and finally leads to matrix upregulation in mesangial cells (MCs). It has been reported that glucose-induced PKC-β1 activation is dependent on caveolin-1 and the presence of...
β-Adrenergic receptors (β-ARs) are G protein-coupled involved in important physiological and pathological processes related to blood pressure cardiac activity. The inhibition of β1-ARs could be beneficial myocardial hypertrophy, ischemia failure. Several carbazole-based compounds have been described as promising β-blockers. Herein, we investigate the capability a carbazole derivative three simp...
Elevated levels of the immunoregulatory cytokine TGF-β1 in cancer and HIV infection have been linked to the suppression of protective immune responses. The transcriptional regulation of TGF-β1 is complex and still not completely understood. We report here for the first time that the transcription factor GLI2 regulates the expression of TGF-β1 in human CD4(+) T cells. In silico screening reveale...
Transforming growth factor-β1 (TGF-β1) is present in porcine enamel extracts and is critical for proper mineralization of tooth enamel. Here, we show that the mRNA of latent TGF-β1 is expressed throughout amelogenesis. Latent TGF-β1 is activated by matrix metalloproteinase 20 (MMP20), coinciding with amelogenin processing by the same proteinase. Activated TGF-β1 binds to the major amelogenin cl...
AIMS Inhibitory G (Gi) proteins have been proposed to be cardioprotective. We investigated effects of Gαi2 knockout on cardiac function and survival in a murine heart failure model of cardiac β1-adrenoceptor overexpression. METHODS AND RESULTS β1-transgenic mice lacking Gαi2 (β1-tg/Gαi2 (-/-)) were compared with wild-type mice and littermates either overexpressing cardiac β1-adrenoceptors (β1...
Transforming growth factor beta 1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) in kidney epithelial cells plays a key role in renal tubulointerstitial fibrosis in chronic kidney diseases. As hypoxia-inducible factor (HIF)-1α is found to mediate TGF-β1-induced signaling pathway, we tested the hypothesis that HIF-1α and its upstream regulator prolyl hydroxylase domain-containing prote...
