Free Radicals 130-142 tumor necrosis factor Mus musculus 80-102 2745981-3 1989 Both iron chelators and free radical scavengers inhibited this enhanced secretion of TNF, implying the involvement of free radicals via a Fenton-type reaction. Free Radicals 118-131 tumor necrosis factor Mus musculus 85-88 3653925-1 1987 Previous work on the mechanism of tumour-cell killing by the macrophage product tumour necrosis factor (TNF) is consistent with a free radical-induced process. Free Radicals 130-142 tumor necrosis factor Mus musculus 104-107 3653925-2 1987 In this study, free-radical involvement was sought by (i) investigating the effects on TNF cytolysis of anaerobic conditions, free-radical scavengers and inhibitors of two potential pathways of free-radical generation (oxidative phosphorylation and arachidonate metabolism) and (ii) looking for increased malonyldialdehyde (MDA) production in TNF-treated cells (MDA is a free radical-induced lipid peroxidation product). Free Radicals 15-27 tumor necrosis factor Mus musculus 87-90 3653925-2 1987 In this study, free-radical involvement was sought by (i) investigating the effects on TNF cytolysis of anaerobic conditions, free-radical scavengers and inhibitors of two potential pathways of free-radical generation (oxidative phosphorylation and arachidonate metabolism) and (ii) looking for increased malonyldialdehyde (MDA) production in TNF-treated cells (MDA is a free radical-induced lipid peroxidation product). Free Radicals 15-27 tumor necrosis factor Mus musculus 343-346 23082993-2 2013 Both cellular and cell-free tests show that carbon associated to quartz completely inhibits the typical free radical generation of quartz dusts (through Fenton activity and homolytic cleavage of a C-H bond) and suppresses the oxidative stress and inflammation induced by quartz alone on MH-S murine macrophage cells (lipid peroxidation, nitric oxide release, and tumor necrosis factor-alpha synthesis). Free Radicals 104-116 tumor necrosis factor Mus musculus 363-390 22343416-4 2012 The free radical-mediated oxidation of cellular macromolecules, which was NADPH oxidase and P2X7 receptor-dependent, correlated well with the release of TNF-alpha and MCP-2 from Kupffer cells. Free Radicals 4-16 tumor necrosis factor Mus musculus 153-162 15046874-2 2004 The mechanisms by which TNF reduces neuronal loss after brain injury may involve the up-regulation of proteins that maintain calcium homeostasis or reduce free radical generation. Free Radicals 155-167 tumor necrosis factor Mus musculus 24-27 11679964-3 2001 With this model, it is now possible to evaluate whether free radicals are directly toxic or act as redox regulators of TNF-alpha production. Free Radicals 56-69 tumor necrosis factor Mus musculus 119-128 11018074-7 2000 These data strongly support the hypothesis that free radicals from NADPH oxidase in hepatic Kupffer cells play a predominant role in the pathogenesis of early alcohol-induced hepatitis by activating NF-kappaB, which activates production of cytotoxic TNF-alpha. Free Radicals 48-61 tumor necrosis factor Mus musculus 250-259 10336540-8 1999 Because tepoxalin suppresses the release of free radicals, PDTC scavenges free radicals and Bcl-2 is an antioxidant protein, free radicals are among the key mediators of this TNF-induced killing event. Free Radicals 44-57 tumor necrosis factor Mus musculus 175-178 10336540-8 1999 Because tepoxalin suppresses the release of free radicals, PDTC scavenges free radicals and Bcl-2 is an antioxidant protein, free radicals are among the key mediators of this TNF-induced killing event.
