Syngeneic graft-versus-host disease (SGVHD) develops in mice following lethal irradiation, reconstitution with syngeneic bone marrow (BM) and treatment with a short course of the immunosuppressive agent cyclosporine A (CsA). The development of SGVHD is a complex process resulting from the cooperative interaction of multiple effector cell populations and inflammatory mediators contributing to th...
Airway remodeling, pathological changes in the lung structure, is a characteristic feature of chronic asthma. The changes include bronchial epithelial hyperplasia and hypertrophy, excess production of mucus, and fibroblast proliferation in the lung. On the other hand, it has been known that both nitric oxide and superoxide anion are increased in exhaled air of asthmatic patients. These molecule...

Bioconversion of glyceryl trinitrate (GTN) into nitric oxide (NO) by aldehyde dehydrogenase-2 (ALDH-2) is a crucial mechanism which drives vasodilatory and antiplatelet effect of organic nitrates in vitro and in vivo. Oxidative stress generated by overproduction of free radical species, mostly superoxide anions and NO-derived peroxynitrite, has been suggested to play a pivotal role in the devel...

Neurophysiol. tase (SOD) and catalase, enzymes that catalyze the re80: 452–457, 1998. Long-term potentiation (LTP) in hippocampal moval of superoxide and hydrogen peroxide, respectively, area CA1 is generally dependent on N-methy...
Acromegaly [overproduction of GH (growth hormone)] is associated with cardiovascular disease. Transgenic mice overexpressing bGH (bovine GH) develop hypertension and hypercholesterolaemia and could be a model for cardiovascular disease in acromegaly. The aims of the present study were to investigate the effects of excess GH on vascular function and to test whether oxidative stress affects endot...
We previously showed that the stimulation of heme oxygenase-1 expression by high glucose and hydrogen peroxide (H(2)O(2)) in cultured rat islets is prevented by antioxidants and suggested that this effect of high glucose results from an oxidative stress. However, the role of oxidative stress in high-glucose-induced beta-cell dysfunction is unclear. We therefore compared the preventative effects...
The signaling pathways leading to high NaCl-induced activation of the transcription factor tonicity-responsive enhancer binding protein/osmotic response element binding protein (TonEBP/OREBP) remain incompletely understood. High NaCl has been reported to produce oxidative stress. Reactive oxygen species (ROS), which are a component of oxidative stress, contribute to regulation of transcription ...
