SCOPE: We evaluated the effect of olive oils with different phenolic content in high-fat diets (HFDs) on hypertrophy and inflammation in adipose tissue and associated atherosclerosis, in the context of obesity. METHODS AND RESULTS: We used Ldlr-/-.Leiden mice fed three different HFDs for 32 weeks and compared them with mice fed the standard low-fat diet (LFD). The different fats provided in the HFDs were: lard (HFD-L), extra-virgin olive oil (79 mg kg-1 of phenolic compounds, HFD-EVOO), or extra-virgin olive oil rich in phenolic compounds (444mg kg-1 of phenolic compounds, HFD-OL)...

Among several pathological mechanisms involved in diabetic nephropathy, oxidative stress, inflammation, and apoptosis play a prominent role. Fenofibrate, a peroxisome proliferator-activated receptor-α (PPAR-α) agonist, has markedly improved oxidative stress and inflammatory responses, but there is no evidence about its effects on interleukin-18 (IL-18), NADPH oxidase type 4 (NOX-4), and p53 expression in diabetic kidneys. The aim of this study was to evaluate possible effects of fenofibrate on improving the underlying mechanisms of diabetic nephropathy...

The lack of current treatments for amyotrophic lateral sclerosis (ALS) highlights the need of a comprehensive understanding of the biological mechanisms of the disease. A consistent neuropathological feature of ALS is the extensive inflammation around motor neurons and axonal degeneration, evidenced by accumulation of reactive astrocytes and activated microglia. Final products of inflammatory processes may be detected as a screening tool to identify treatment response. Herein, we focus on (a) detection of arachidonic acid (AA) metabolization products by lipoxygenase (LOX) and prostaglandin endoperoxide H synthase in SOD1G93A mice and (b) evaluate its response to the electrophilic nitro-oleic acid (NO2 -OA)...

High circulatory insulin and leptin followed by underlying inflammation are often ascribed to the ectopic manifestations in non-alcoholic fatty liver disease (NAFLD) but the exact molecular pathways remain unclear. We have shown previously that CYP2E1-mediated oxidative stress and circulating leptin in NAFLD is associated with renal disease severity. Extending the studies, we hypothesized that high circulatory leptin in NAFLD causes renal mesangial cell activation and tubular inflammation via a NOX2 dependent pathway that upregulates proinflammatory miR21...

Continuous intake of alcohol leads to liver cirrhosis because of imbalance of oxidative stress/antioxidative defense and chronic 'sterile inflammation'. Hepatorenal syndrome (HRS) is the most severe complication of liver cirrhosis. The aim of our study was to assess: (1) the oxidative stress/antioxidative defense markers such as malondialdehyde (MDA), oxidative glutathione (GSH) and glutathione S-transferase (GST), (2) inflammation [C-reactive protein (CRP)], and (3) nitrate/nitrite levels (NOx) and its substrate L-arginine level...

Oxidative damage, inflammation and apoptosis play significant roles in diabetic nephropathy. Previous studies demonstrated anti-inflammatory and anti-oxidative effects of crocin, but there is no evidence about its effects on IL-18, NOX-4, and p53 expression in diabetic kidneys. The aim of this study was to evaluate possible effects of crocin on improving main mechanisms underlying diabetic nephropathy. Male Wistar rats were randomly divided into four separate groups as normal (C), normal treated (CC), diabetic (D), and diabetic treated (DC) (n = 6)...

Gastroschisis (GS) is an abdominal wall defect that results in histological and morphological changes leading to intestinal motility perturbation and impaired absorption of nutrients. Due to its anti-inflammatory, antioxidant, and neuroprotective effects, cannabidiol (CBD) has been used as a therapeutic agent in many diseases. Our aim was to test the effect of maternal CBD in the intestine of an experimental model of GS. Pregnant rats were treated over 3 days with CBD (30 mg/kg) after the surgical induction of GS (day 18...

Nitro-fatty acids (NO2 -FA) have been widely studied with regard to their identification, structural characterization, and biological actions. NO2 -FA could also be present endogenously esterified to phospholipids (PL), and NO2 -PL were already detected in cardiac mitochondria from diabetic rats and cardiomyoblasts subjected to starvation. However, the biological actions of NO2 -PL have been overlooked. In this study, we evaluate the antioxidant and anti-inflammatory potential of the nitrated 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) formed in vitro by incubation with NO2 BF4 , in a well-recognized mimetic model of nitroxidative stress...

The Arctic flora hosts a limited number of species due to its extreme environmental conditions which also yield novel and unique secondary metabolites from withstanding plants. Considering a lack of research on bioactivity potential of Arctic flora, Ranunculus hyperboreus, an Arctic plant, was studied for its anti-inflammatory potential as a part of ongoing research on discovering novel natural bioactive products. Solvent-based fractions (H2O, n-BuOH, 85% aq. MeOH, n-hexane) from R. hyperboreus extract were observed to decrease the elevated nitrate amount during the inflammatory response of lipopolysaccharide-induced mouse macrophage RAW264...

BACKGROUND: Cell signaling through nitric oxide (NO) is a multifaceted mechanism, which regulates metabolic activities and fate in different tissues. The peroxynitrite (ONOO-) formed as reaction product of nitric oxide radical and superoxide interacts with cell membrane phospholipids and proteins causing damage. OBJECTIVE: The reaction kinetics to form nitrotyrosine (ONOO-tyrosine) and/or nitrosylated cysteine (ONOO-cysteine) in protein molecules during posttranslational modification and nitration of lipids are therefore critical in determining cells' signaling mechanism for survival or apoptosis...

Conjugated linoleic acid (CLA) is a prime substrate for intra-gastric nitration giving rise to the formation of nitro-conjugated linoleic acid (NO2 -CLA). Herein, NO2 -CLA generation is demonstrated within the context of acute inflammatory responses both in vitro and in vivo. Macrophage activation resulted in dose- and time-dependent CLA nitration and also in the production of secondary electrophilic and non-electrophilic derivatives. Both exogenous NO2 -CLA as well as that generated in situ, attenuated NF-κB-dependent gene expression, decreased pro-inflammatory cytokine production and up-regulated Nrf2-regulated proteins...

Silver nanoparticles (Ag NPs) are known for their antibacterial properties and are used in a growing number of nano-enabled products, with inevitable concerns for releases to the environment. Nanoparticles may also be antigenic and toxic to the haematopoietic system, but the immunotoxic effect of Ag NPs on non-target species such as fishes is poorly understood. This study aimed to assess the effect of Ag NP exposure via the water on the haematopoietic system of rainbow trout, Oncorhynchus mykiss, and to determine whether or not the hazard from Ag NPs was different from that of AgNO3 ...
