1 Here we show that TGF-beta1 induces the expression of macrophage-CSF (M-CSF) in vascular endothelial cells via a signaling pathway(s) involving hydrogen peroxide (H2O2). Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
2 Here we show that TGF-beta1 induces the expression of macrophage-CSF (M-CSF) in vascular endothelial cells via a signaling pathway(s) involving hydrogen peroxide (H2O2). Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
3 Here we show that TGF-beta1 induces the expression of macrophage-CSF (M-CSF) in vascular endothelial cells via a signaling pathway(s) involving hydrogen peroxide (H2O2). Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
4 Here we show that TGF-beta1 induces the expression of macrophage-CSF (M-CSF) in vascular endothelial cells via a signaling pathway(s) involving hydrogen peroxide (H2O2). Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
5 Furthermore, the TGF-beta1-induced M-CSF mRNA expression was inhibited by catalase, but not by superoxide dismutase, suggesting that H2O2 rather than superoxide anion (O2.-) is the primary mediator of the effects of TGF-beta1. Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
6 In a concentration-dependent manner, treatment with exogenous H2O2 produced 14- and 4.6-fold increases in M-CSF promoter activity and mRNA expression, respectively. Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
7 These results indicate that the generation of H2O2 and activation of NF-kappaB by TGF-beta1 are required for the induction of M-CSF gene transcription. Hydrogen Peroxide colony stimulating factor 1 Homo sapiens
