Sulfur Dioxide 97-111 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 118-144 18664325-1 2008 AIM: The present study was designed to explore the endogenous production and localization of the sulfur dioxide (SO2)/aspartate aminotransferase pathway in vascular tissues of rats and to examine its vasorelaxant effect on isolated aortic rings,as well as the possible mechanisms. Sulfur Dioxide 113-116 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 118-144 18664325-8 2008 The aortic aspartate aminotransferase mRNA located in endothelia and vascular smooth muscle cells beneath the endothelial layer.Furthermore, a physiological dose of the SO2 derivatives (Na2SO3/NaHSO3) relaxed isolated artery rings slightly, whereas higher doses (1-12 mmol/L) relaxed rings in a concentration-dependent manner. Sulfur Dioxide 169-172 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 11-37 29760703-5 2018 We found that endogenous H2S deficiency caused by cystathionine-gamma-lyase (CSE) knockdown increased endogenous SO2 level in endothelial cells and enhanced the enzymatic activity of AAT, a major SO2 synthesis enzyme, without affecting the expressions of AAT1 and AAT2. Sulfur Dioxide 113-116 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 183-186 29760703-9 2018 Furthermore, an AAT inhibitor l-aspartate-beta-hydroxamate (HDX), which blocked the upregulation of endogenous SO2/AAT generation induced by CSE knockdown, aggravated CSE knockdown-activated nuclear factor-kappaB pathway in the endothelial cells and its downstream inflammatory factors including ICAM-1, TNF-alpha, and IL-6. Sulfur Dioxide 111-114 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 16-19 29760703-9 2018 Furthermore, an AAT inhibitor l-aspartate-beta-hydroxamate (HDX), which blocked the upregulation of endogenous SO2/AAT generation induced by CSE knockdown, aggravated CSE knockdown-activated nuclear factor-kappaB pathway in the endothelial cells and its downstream inflammatory factors including ICAM-1, TNF-alpha, and IL-6. Sulfur Dioxide 111-114 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 115-118 29760703-10 2018 In in vivo experiment, H2S donor restored the deficiency of endogenous H2S production induced by MCT, and reversed the upregulation of endogenous SO2/AAT pathway via sulfhydrating AAT1 and AAT2. Sulfur Dioxide 146-149 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 150-153 29760703-12 2018 In conclusion, for the first time, the present study showed that H2S inhibited endogenous SO2 generation by inactivating AAT via the sulfhydration of AAT1/2; and the increased endogenous SO2 generation might play a compensatory role when H2S/CSE pathway was downregulated, thereby exerting protective effects in endothelial inflammatory responses in vitro and in vivo. Sulfur Dioxide 90-93 glutamic-oxaloacetic transaminase 2 Rattus norvegicus 121-124 29760703-5 2018 We found that endogenous H2S deficiency caused by cystathionine-gamma-lyase (CSE) knockdown increased endogenous SO2 level in endothelial cells and enhanced the enzymatic activity of AAT, a major SO2 synthesis enzyme, without affecting the expressions of AAT1 and AAT2.
