Oxidative stress plays an important role in the pathogenesis of cardiovascular diseases. Salidroside (SAL), one of the main effective constituents of Rhodiola rosea, has been reported to suppress oxidative stress-induced cardiomyocyte injury and necrosis by promoting transcription of nuclear factor E2-related factor 2 (Nrf2)-regulated genes such as heme oxygenase-1 (HO-1) and NAD(P)H dehydrogen...
With secure and dependable antihypertensive effects, telmisartan is an antihypertensive drug. Telmisartan was reported showing distinct neuroprotective effect in cerebral IR injury but the underlying mechanisms are still unclear. The aim of this study was to evaluate the effect of telmisartan prevents cerebral ischemia-reperfusion (I/R) injury-mediated oxidative stress and inflammation in model...
Oxidative stress-induced podocyte injury is one of the major mechanisms underlying the initiation and progression of glomerulosclerosis. 5'-AMP-activated protein kinase (AMPK), a serine/threonine kinase that senses intracellular energy status and maintains energy homeostasis, is reported to have antioxidative effects. However, little is known about its application and mechanism. In this study, ...
Increased oxidative stress is a major characteristic of restenosis after angioplasty. The oxidative stress is mainly created by oxidants such as reactive oxygen species (ROS), which are assumed to play an important role in neointima formation after angioplasty. DNA is a sensitive target for oxidants; however, oxidative DNA damage remains a poorly examined field in the pathogenesis of restenosis...
BACKGROUND Oxidative stress due to reactive oxygen species (ROS) is thought to play a considerable role in ischemia/reperfusion (I/R) injury that impairs cardiac function. The present study examined oxidative damage in I/R injury and investigated the correlation between oxidative stress and impaired cardiac function after I/R injury of the isolated rat heart. METHODS Hearts isolated from male...
BACKGROUND Sulforaphane (SFN), a phytochemical found in abundance in broccoli sprouts, potently induces a variety of antioxidant enzymes, and thereby protects cells from injury induced by various kinds of oxidative stresses. It has been suggested that both H. pylori infection and intake of non-steroidal anti-inflammatory drugs (NSAIDs) induce chronic oxidative stress in gastrointestinal (GI) mu...
Traumatic axonal injury (TAI), a feature of traumatic brain injury (TBI), progressively evolves over hours through impaired axonal transport and is thought to be a major contributor to cognitive dysfunction. In spite of various studies suggesting that pharmacologic or physiologic interventions might reduce TAI, clinical neuroprotective treatments are still unavailable. Edaravone, a free radical...
The role of endogenous hepatocyte synthesis of nitric oxide (NO) in states of oxidative stress is largely unknown. In a model of rat hepatocytes in primary culture, NO production was induced by exposure to interleukin-1beta (IL-1beta, 50 ng/ml). Acetaminophen-mediated oxidative injury was analyzed in unstimulated and stimulated hepatocytes in the presence and absence of N-methyl-L-arginine, a s...
Purpose: To investigate the effect of FOXO4 on cerebral ischemia/reperfusion (CIR) injury and underlying mechanism.Methods: An in vitro (IR) model was achieved using oxygen-glucose deprivation/reoxygenation (OGD/R). Expression RNA protein determined quantitative real time polymerase chain reaction (qRT-PCR) western blotting, respectively. Cell viability apoptosis were MTT assay flow cytometry, ...
