BackgroundThe retinal vascular endothelial cells can be damaged by oxidative stress even in the early stage of diabetic retinopathy (DR). This study aimed to investigate protective effect curcumin on rat (RRVECs) high glucose circumstance.ObjectiveThe cultured RRVECs were identified and characterized both vWF CD31 immunofluorescence expression. The activation ROS/NF-κB signal pathway was examin...

Chronic systemic inflammation is implicated in the systemic manifestations and, probably, the excess mortality risk of chronic obstructive pulmonary disease (COPD). The role of nuclear factor (NF)-κB repressing factor (NRF), a DNA-binding, protein-inhibiting NF-κB response gene, in human diseases has not been explored. We hypothesised that the NRF-negative regulatory mechanism is impaired in CO...

This study investigated the possible effects and molecular mechanisms of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced hemorrhagic cystitis (HC) in rats. Inflammation response was assessed by histopathology and serum cytokines levels. We determined the protein expressions of nuclear transcription factor kappa-B (NF-κB), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (...

Ginseng is known to have antistress effects. Previously, red ginseng (RG) was shown to repress stress-induced peptidyl arginine deiminase type IV (PADI4) via estrogen receptor β (ERβ) in the brain, thus inhibiting brain cell apoptosis. Moreover, tumor necrosis factor (TNF)-α plays a critical role in immobilization (IMO) stress. However, the signaling pathway of RG-mediated repressesion of infla...

Oxidative stress plays an important role in the pathogenesis of inflammatory bowel disease (IBD), including Crohn's disease (CrD). High levels of Reactive Oxygen Species (ROS) induce the activation of the redox-sensitive nuclear transcription factor kappa-B (NF-κB), which in turn triggers the inflammatory mediators. Butyrate decreases pro-inflammatory cytokine expression by the lamina propria m...

Background: Chronic inflammation and oxidative stress are the two essential factors determining ulcerative colitis (UC) onset and severity status. In present study, we aimed to investigate short-term effects of ginger (Zingiber officinale) as a well-known antioxidant and anti-inflammatory agent on the quality of life, disease activity index and some of inflammatory and oxidative stress factors ...

The overproduction of reactive oxygen species (ROS) plays a central role in the pathogenesis of endothelial damage in diabetes. To assess the effect of oat on experimental diabetic retinopathy, five groups of Albino rats were studied: nondiabetic control, untreated diabetic, and diabetic rats treated with 5%, 10%, and 20% (W/W) oat of the diet for 12 weeks. Novel data were obtained in this stud...

Tormentic acid (TA) is a triterpene isolated from the stem bark of the plant Vochysia divergens and has been reported to exhibit anticancer, anti‑inflammatory and anti‑atherogenic properties. However, the functions of TA in hydrogen peroxide (H2O2)‑induced oxidative stress and inflammation in rat vascular smooth muscle cells (RVSMCs) remain unclear. Therefore, the present study aimed to investi...

MAP/Microtubule affinity-regulating kinase 4 (Mark4) plays an important role in the regulation of microtubule organization, adipogenesis and apoptosis. However, the role of Mark4 plays in oxidative stress and inflammation are poorly understood. In this study, we found Mark4 was induced by high fat diet (HFD) while PPARγ was elevated significantly in mice adipocytes. Further analyses revealed Ma...

Activation of the immune system in the central nervous system and oxidative stress play important roles in traumatic brain injury (TBI)-induced cognitive impairment. Rhamnetin possesses anti-inflammatory and anti-oxidative properties. This study aimed to detect the possible effects of rhamnetin on cognitive deficit, hippocampal inflammatory factors, and oxidative stress in rats with TBI. In thi...
