1 In this study, the potential for regulation of this novel TGF-beta1-activated oxidase in fibroblasts by protein tyrosine phosphorylation was examined. Tyrosine transforming growth factor beta 1 Homo sapiens
2 The protein-tyrosine kinase inhibitors genistein and herbimycin A inhibited TGF-beta1-induced protein tyrosine phosphorylation, NADH oxidase activation, and H2O2 production in a dose-dependent manner. Tyrosine transforming growth factor beta 1 Homo sapiens
3 These results suggest that protein tyrosine phosphorylation by a nonreceptor protein-tyrosine kinase(s) regulates the activity of the TGF-beta1-responsive H2O2-generating NADH oxidase in human lung fibroblasts. Tyrosine transforming growth factor beta 1 Homo sapiens
4 Additionally, this study demonstrates that TGF-beta1, which binds to a serine-threonine kinase receptor, is able to induce protein tyrosine phosphorylation in a delayed manner via a signaling pathway that requires transcriptional activation. Tyrosine transforming growth factor beta 1 Homo sapiens
