Transforming growth factors (TGF) are potent multifunctional polypeptides that are involved in renal function and glomerular sclerosis. We postulated that dietary salt modified renal production of TGF-β. An increase in dietary salt produced sustained increases in steady-state levels of mRNA for TGF-β1, -β2, and -β3 in the rat kidney. While serum concentration of TGF-β1 did not change, the 8.0% ...
Carrageenans, a family of polysulphated carbohydrates, inhibited binding of basic fibroblast growth factor (bFGF), transforming growth factor beta 1 (TGF beta 1) and platelet-derived growth factor (PDGF). iota-Carrageenan was the most potent bFGF antagonist (IC50 = 0.4 +/- 0.1 microgram/ml), kappa-carrageenan was the most potent PDGF antagonist (IC50 = 1.7 +/- 1.3 micrograms/ml) and lambda-carr...
Restitution of an epithelial layer after environmental or biological damage is important to maintain the normal function of the respiratory tract. We have investigated the role of transforming growth factor (TGF)-beta isoforms in the repair of layers of 16HBE 14o(-) bronchial epithelial-derived cells after damage by multiple scoring. ELISA showed that both latent TGF-beta1 and TGF-beta2 were co...
Using a rat bone marrow culture system, the effect of transforming growth factor beta 1 (TGF beta 1) on megakaryocyte growth and endoreduplication has been studied. Purified human platelet TGF beta 1 inhibited the number of megakaryocytes that appeared in culture at a half-maximal concentration of 0.66 +/- 0.21 ng/mL and inhibited megakaryocyte endoreduplication at a half-maximal concentration ...
Transforming growth factor-betas (TGF-betas) are pleiotropic cytokines involved in development and maintenance of the nervous system. In several neural lesion paradigms, TGF-beta1 exerts potent neuroprotective effects. Neurons treated with TGF-beta1 activated the canonical TGF-beta receptor I/activin-like kinase receptor 5 (ALK5) pathway. The transcription factor nuclear factor-kappaB (NF-kappa...
Background and Objectives: Different diets have important roles in human health and aging. In the current study, we aimed to characterize the Klotho, an anti-aging protein, gene expression and protein level in the serum and assess the protein levels of Transforming growth factor-β and Platelet-derived growth factor in old rats which treated with different diets (high-fat, high-protein, low calo...
Alterations in the serum concentration of transforming growth factor beta-1 (TGFbeta1) have been observed in gastric cancer patients. No study, however, has ever examined the association between the serum TGFbeta1 level and stomach cancer prospectively. We conducted a prospective, nested case-control analysis among apparently healthy men and women who were followed for up to 8 years in the JACC...
CD69 is induced after activation of leukocytes at inflammatory sites, but its physiological role during inflammation remains unknown. We explored the role of CD69 in autoimmune reactivity by analyzing a model of collagen-induced arthritis (CIA) in WT and CD69-deficient mice. CD69-/- mice showed higher incidence and severity of CIA, with exacerbated T and B cell immune responses to type II colla...
