The infiltration of red blood cells into atheromatous plaques is implicated in atherogenesis. Inside the lesion, hemoglobin (Hb) is oxidized to ferri- and ferrylHb which exhibit prooxidant and proinflammatory activities. Cystathione gamma-lyase- (CSE-) derived H2 S has been suggested to possess various antiatherogenic actions. Expression of CSE was upregulated predominantly in macrophages, foam cells, and myofibroblasts of human atherosclerotic lesions derived from carotid artery specimens of patients. A similar pattern was observed in aortic lesions of apolipoprotein E-deficient mice on high-fat diet...

Apolipoprotein A-I Binding Protein (AIBP) has been shown to augment cholesterol efflux from endothelial cells and macrophages. In zebrafish and mice, AIBP-mediated regulation of cholesterol levels in the plasma membrane of endothelial cells controls angiogenesis. The goal of this work was to evaluate metabolic changes and atherosclerosis in AIBP loss-of-function and gain-of-function animal studies. Here we show that Apoa1bp-/-Ldlr-/- mice fed a high-cholesterol, high-fat diet had exacerbated weight gain, liver steatosis, glucose intolerance, hypercholesterolemia and hypertriglyceridemia, and larger atherosclerotic lesions compared to Ldlr-/- mice...

Unesterified cholesterol controls the fluidity, permeability and electrical properties of eukaryotic cell membranes. Consequently, cholesterol levels in the retina and the brain are tightly regulated whereas depletion or oversupply caused by diet or heredity contribute to neurodegenerative diseases and vision loss. Astroglia play a central role in the biosynthesis, uptake and transport of cholesterol and also drive inflammatory signaling under hypercholesterolemic conditions associated with high-fat diet (diabetes) and neurodegenerative disease...

Introduction: Obesity is associated with an increased risk of nonalcoholic fatty liver disease (NAFLD). While Magnetic Resonance Imaging (MRI) is a non-invasive gold standard to detect fatty liver, we demonstrate a low-cost and portable electrical impedance tomography (EIT) approach with circumferential abdominal electrodes for liver conductivity measurements. Methods and Results: A finite element model (FEM) was established to simulate decremental liver conductivity in response to incremental liver lipid content...

Dementia and cognitive decline have become worldwide public health problems, and it was recently reported that life-style related diseases and obesity are key risk factors in dementia. Iso-α-acids, hop-derived bitter components of beer, have been reported to have various physiological functions via activation of peroxisome proliferator-activated receptor γ. In this report, we demonstrated that daily intake of iso-α-acids suppresses inflammations in the hippocampus and improves cognitive decline induced by high fat diet (HFD)...

The growth receptor binding protein Grb10 is an imprinted gene product and a key negative regulator of the insulin, IGF1 and mTORC1 signaling pathways. Grb10 is highly expressed in mouse fetal liver but almost completely silenced in adult mice, suggesting a potential detrimental role of this protein in adult liver function. Here we show that the grb10 gene could be reactivated in adult mouse liver by acute endoplasmic reticulum stress (ER stress) such as tunicamycin or a short-term high fat diet (HFD) challenge, concurrently with increased unfolded protein response (UPR) and hepatosteatosis...

Background & Aims: Nonalcoholic steatohepatitis (NASH) is associated with oxidative stress. We surmised that pharmacologic activation of NF-E2 p45-related factor 2 (Nrf2) using the acetylenic tricyclic bis(cyano enone) TBE-31 would suppress NASH because Nrf2 is a transcriptional master regulator of intracellular redox homeostasis. Methods: Nrf2 +/+ and Nrf2 -/- C57BL/6 mice were fed a high-fat plus fructose (HFFr) or regular chow diet for 16 weeks or 30 weeks, and then treated for the final 6 weeks, while still being fed the same HFFr or regular chow diets, with either TBE-31 or dimethyl sulfoxide vehicle control...

Background: Metabolic syndrome (MS) is a global epidemic that has great socioeconomic and public health implications. This study reports observed effects of the Shexiang Baoxin Pill (SBP) in a rat model of MS and explores its underlying mechanisms of action. Methods: A diet-induced rat model of MS was established according to accepted methods, and the rats were randomly divided into two groups: a control group (0.9% NaCl, 100 mg/kg• d) and a SBP-treated group (SBP, 100 mg/kg• d). Systolic blood pressures, fasting blood glucose (FBS) levels, triglyceride (TG) levels, high-density lipoprotein cholesterol (HDL-C) levels, body weights, and abdominal perimeters were dynamically monitored and analyzed...

OBJECTIVE: The ability of adipose tissue to expand and contract in response to fluctuations in nutrient availability is essential for the maintenance of whole-body metabolic homeostasis. Given the nutrient scarcity that mammals faced for millions of years, programs involved in this adipose plasticity were likely evolved to be highly efficient in promoting lipid storage. Ironically, this previously advantageous feature may now represent a metabolic liability given the caloric excess of modern society...

Ginseng and probiotics have anti-obese effects in mice fed a high-fat diet(HFD). Absorption of ginsenoside and colonization of probiotics occur in the intestine. In this study, the mixture of fermented ginseng and two probiotics, Bifidobacterium longum BORI and Lactobacillus paracasei CH88, was administered to HFD fed mice for 9 weeks. The mixture significantly suppressed weight gain ( p < 0.05, n = 8) and lipid deposition in the liver and adipose tissues as well as increased the mice's food intake. The adipocyte size of the adipose tissue was significantly decreased in the mixture group, especially when 0...

AIMS: Fatty acid binding protein 4 (FABP4) inhibitors have been proposed as potential therapeutic approaches against insulin resistance-related inflammation and type 2 diabetes mellitus. However, the underlying molecular mechanisms by which these molecules drive these effects in skeletal muscle remain unknown. Here, we assessed whether the FABP4 inhibitor BMS309403 prevented lipid-induced endoplasmic reticulum (ER) stress-associated inflammation in skeletal muscle. MATERIALS AND METHODS: The BMS309403 treatment was assessed both in the skeletal muscle of high-fat diet (HFD)-fed mice and in palmitate-stimulated C2C12 myotubes...
