IGF-I production by adult rat hepatocytes is stimulated by transforming growth factor-alpha and transforming growth factor-beta1.
Previously, we have observed that epidermal growth factor (EGF), a potent mitogen for cultured hepatocytes, stimulates the production of IGF-I and IGF-binding proteins (IGFBPs) by cultured hepatocytes from adult rats. This study was undertaken to investigate the possibility that other growth factors of hepatic origin could specifically be involved in the regulation of IGF-I and IGFBP expression...
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 کاملTyrosine phosphorylation regulates H2O2 production in lung fibroblasts stimulated by transforming growth factor beta1.
Transforming growth factor beta1 (TGF-beta1) is a multifunctional, profibrotic cytokine involved in cellular growth and differentiation. We have previously described a cell surface-associated H2O2-generating NADH:flavin:O2 oxidoreductase (referred to as NADH oxidase) activity in human lung fibroblasts induced by TGF-beta1 (Thannickal, V. J., and Fanburg, B. L. (1995) J. Biol. Chem. 270, 30334-3...
متن کاملThe recombinant proregion of transforming growth factor beta1 (latency-associated peptide) inhibits active transforming growth factor beta1 in transgenic mice.
All three isoforms of transforming growth factors beta (TGF-betal, TGF-beta2, and TGF-beta3) are secreted as latent complexes and activated extracellularly, leading to the release of the mature cytokines from their noncovalently associated proregions, also known as latency-associated peptides (LAPs). The LAP region of TGF-beta1 was expressed in a baculovirus expression system and purified to ho...
متن کاملMyofibroblasts and Transforming Growth Factor-Beta1 in Reactive Gingival Overgrowths
OBJECTIVES The purpose of this study was to evaluate the oral health-related quality of life of patients treated with implant-supported mandibular overdentures and to compare the attachment systems used. MATERIAL AND METHODS The presence of myofibroblasts as well as transforming growth factor-beta1 was examined in twenty cases of fibrous epulis and 22 ossifying fibrous epulis, using immunohis...
