We hypothesized that supplementing finishing diets with palm oil would promote adipogenic gene expression but depress stearoyl-CoA desaturase (SCD) gene expression in intramuscular (i.m.) adipose tissues of Hanwoo steers during fattening period (from 16 to 32 mon of age). Fourteen Hanwoo steers were allotted randomly to 2 groups of 7 steers based on initial BW and fed either a basal diet (control) or the basal diet supplemented with 5% palm oil (BDSP). At slaughter, i.m. adipose tissue was harvested for analysis of adipogenic gene expression and fatty acid composition...

REVIEW
Edda Cava, Nai Chien Yeat, Bettina Mittendorfer
Weight loss is the cornerstone of therapy for people with obesity because it can ameliorate or completely resolve the metabolic risk factors for diabetes, coronary artery disease, and obesity-associated cancers. The potential health benefits of diet-induced weight loss are thought to be compromised by the weight-loss-associated loss of lean body mass, which could increase the risk of sarcopenia (low muscle mass and impaired muscle function). The objective of this review is to provide an overview of what is known about weight-loss-induced muscle loss and its implications for overall physical function (e...

The metabolic syndrome could be induced by high fat diet, leading to cardiovascular diseases, such as myocardial damage. Inflammation response and oxidative stress have been reported to be involved in high fat-induced heart injury, and the molecular mechanism is not fully understood. The NOD-like protein family member, NLRC5, could interact with IKKα to inhibit IKK complex activation. In our study, high fat diet-feeding mice showed cardiac fibrosis, inflammation and oxidative stress through collagen accumulation, TLR4/NF-κB and MAPKs signaling pathways activation...

Cancer cachexia is characterised by involuntary weight loss associated with systemic inflammation and metabolic changes. Studies aimed at maintaining lean body mass in cachectic tumour-bearing hosts have made important contributions reducing the number of deaths and improving the quality of life. In recent years, leucine has demonstrated effective action in maintaining lean body mass by decreasing muscle protein degradation. Currently, there is a growing need to understand how leucine stimulates protein synthesis and acts protectively in a cachectic organism...

Background -Atherosclerotic plaque formation results from chronic inflammation and fibroproliferative remodeling in the vascular wall. We previously demonstrated that both human and mouse atherosclerotic plaques show elevated expression of EphA2, a guidance molecule involved in cell-cell interactions and tumorigenesis. Methods -Here, we assessed EphA2's role in atherosclerosis by deleting EphA2 in a mouse model of atherosclerosis (Apoe(-/-)) and by assessing EphA2 function in multiple vascular cell culture models...

Atherosclerosis is a complex inflammatory disease associated with elevated levels of atherogenic molecules for leukocyte recruitment. Sinigrin (2-propenylglucosinolate) is found mainly in broccoli, brussels sprouts, and black mustard seeds. Recently, sinigrin has received attention for its role in disease prevention and health promotion. In this study, we examined the effect of sinigrin on development of atherosclerosis in ApoE(-/-) mice and the expression of adhesion molecules in vascular smooth muscle cells (VSMCs)...

OBJECTIVE: Mice with adipocyte-specific inactivation of low-density lipoprotein receptor-related protein-1 (LRP1) are resistant to diet-induced obesity and hyperglycemia because of compensatory thermogenic response by muscle. However, the physiological function of LRP1 in mature adipocytes and its role in cardiovascular disease modulation are unknown. This study compared perivascular adipose tissues (PVAT) from wild-type (adLrp1(+/+) ) and adipocyte-specific LRP1 knockout (adLrp1(-/-)) mice in modulation of atherosclerosis progression...

In vertebrates thyrotropin-releasing hormone (TRH) is a highly conserved neuropeptide that exerts the hormonal control of thyroid-stimulating hormone (TSH) levels as well as neuromodulatory functions. However, a functional equivalent in protostomian animals remains unknown, although TRH receptors are conserved in proto- and deuterostomians. Here we identify a TRH-like neuropeptide precursor in Caenorhabditis elegans that belongs to a bilaterian family of TRH precursors. Using CRISPR/Cas9 and RNAi reverse genetics, we show that TRH-like neuropeptides, through the activation of their receptor TRHR-1, promote growth in Celegans TRH-like peptides from pharyngeal motor neurons are required for normal body size, and knockdown of their receptor in pharyngeal muscle cells reduces growth...

Type 2 diabetes mellitus (T2DM) is a chronic disease characterized by metabolic disturbances in specific tissues. The present work aimed to analyze the effects of xanthohumol (XN) and 8-prenylnaringenin (8PN), two beer-derived polyphenols, in liver and skeletal muscle lipid and glycolytic metabolism in T2DM mice model. Thirty C57Bl/6 mice were randomly divided into five groups: standard diet (control), high-fat diet (DM), high-fat diet plus ethanol (DM-Ethanol), high-fat diet plus 10 mg/L XN (DM-XN) and high-fat diet plus 10 mg/L 8PN (DM-8PN) during 20 weeks...

Statins are efficient cholesterol-lowering medicines utilized worldwide. However, 10% of patients suffer from adverse effects specially related to skeletal muscle function. Pro- or anti-oxidant effects of statins have been reported. Here we hypothesized that statins induce muscle mitochondrial oxidative stress leading to mitochondrial permeability transition (MPT) which may explain statin muscle toxicity. Thus, our aims were to investigate the effects of statin chronic treatment on muscle mitochondrial respiration rates, MPT and redox state indicators in the context of hypercholesterolemia...

Tuna muscle consists of light and dark muscle in approximately equal proportions. However, besides for the light muscle of tuna, cod, sardine, and salmon, few researches have assessed the health-promoting functions of fish protein. Therefore, we evaluated the mechanisms underlying the alteration of lipid storage and cholesterol metabolism following the intake of tuna dark muscle protein (TDMP) by obese type-2 diabetic/obese mice. Four-week-old male KK-A(y) mice were separated into 2 dietary groups, with one group receiving a casein-based diet and the other receiving a diet with the substitution of part of the protein (50%, w/w) by TDMP (TDMP diet) for 4 wk...

There is an emerging consensus that hyperhomocysteinemia is an independent risk factor for cerebral vascular disease and that homocysteine-lowering therapy protects from ischemic stroke. However, the mechanisms by which hyperhomocysteinemia produces abnormalities of cerebral vascular structure and function remain largely undefined. Our objective in this study was to define the mechanistic role of superoxide in hyperhomocysteinemia-induced cerebral vascular dysfunction and hypertrophy. Unlike previous studies, our experimental design included a genetic approach to alter superoxide levels by using superoxide dismutase 1 (SOD1)-deficient mice fed a high methionine/low folate diet to produce hyperhomocysteinemia...

Tumor necrosis factor α (TNFα) is an inflammatory cytokine that plays a central role in obesity-induced insulin resistance. It also controls cellular lipid metabolism but the underlining mechanism is poorly understood. We report here that phosphoinositide 3-kinase enhancer A (PIKE-A) is a novel effector of TNFα to facilitate its metabolic modulation in the skeletal muscle. Depletion of PIKE-A in C2C12 myotubes diminished the inhibitory activities of TNFα on mitochondrial respiration and lipid oxidation, whereas PIKE-A overexpression exacerbated these cellular responses...
