Advanced glycation end products (AGEs) and oxidative stress are elevated with aging and dysmetabolic conditions. Because a Mediterranean (Med) diet reduces oxidative stress, serum AGEs levels, and gene expression related to AGEs metabolism in healthy elderly people, we studied whether supplementation with coenzyme Q10 (CoQ) was of further benefit. Twenty participants aged ≥ 65 (10 men and 10 women) were randomly assigned to each of three isocaloric diets for successive periods of 4 weeks in a crossover design: Med diet, Med + CoQ, and a Western high-saturated-fat diet (SFA diet)...

Dietary interventions dramatically affect metabolic disease and lifespan in various aging models. Here, we profiled liver microRNA (miRNA), coding, and long non-coding RNA (lncRNA) expression by high-throughput deep sequencing in mice across multiple energy intake and expenditure interventions. Strikingly, three dietary intervention network design patterns were uncovered: (1) lifespan-extending interventions largely repressed the expression of miRNAs, lncRNAs, and transposable elements; (2) protein-coding mRNAs with expression positively correlated with long lifespan are highly targeted by miRNAs; and (3) miRNA-targeting interactions mainly target chromatin-related functions...

Hepatic de novo lipogenesis (DNL) converts carbohydrates into triglycerides and is known to influence systemic lipid homoeostasis. Here, we demonstrate that the zinc finger protein Zbtb20 is required for DNL. Mice lacking Zbtb20 in the liver exhibit hypolipidemia and reduced levels of liver triglycerides, along with impaired hepatic lipogenesis. The expression of genes involved in glycolysis and DNL, including that of two ChREBP isoforms, is decreased in livers of knockout mice. Zbtb20 binds to and enhances the activity of the ChREBP-α promoter, suggesting that altered metabolic gene expression is mainly driven by ChREBP...

BACKGROUND: Obese individuals differ in their risk of developing metabolic and cardiovascular complications depending on fat distribution (subcutaneous versus visceral) and adipose tissue (AT) phenotype (hyperplasic versus hypertrophic). However, the exact mechanisms which determine whether an obese individual is metabolically healthy or unhealthy are not clear, and analyses of the underlying pathomechanisms are limited by the lack of suitable in vivo models in which metabolically healthy versus metabolically unhealthy AT accumulation can be specifically induced...

The survival, feeding response, and detoxification mechanism of Rhynchophorus ferrugineus Olivier, a key pest responsible for destruction of date palm, was examined with different extracts of Piper nigrum and its major constituent (piperine) identified by GC-MS. In the present study, toxicity of different extracts of black pepper was evaluated by incorporating diffferent doses of extracts into the artificial diet of red palm weevil larvae. All extracts showed dose-dependent insecticidal activity to the tested eighth-instar red palm weevil larvae...

We tested the hypothesis that dietary whey protein isolate (WPI) affects the intestinal mechanisms related to energy absorption and that the resulting energy deficit is compensated by changes in energy balance to support growth. C57BL/6 mice were provided a diet enriched with WPI with varied sucrose content, and the impact on energy balance related parameters were investigated. As part of a high sucrose diet, WPI reduced the hypothalamic expression of pro-opiomelanocortin gene expression and increased energy intake...

Galanin-like peptide (GALP) is a neuropeptide involved in the regulation of food intake behavior, body weight and energy metabolism. In previous studies, we demonstrated that the intranasal administration of GALP has weight loss effects, although the mechanism of this action was not clarified. The aim of this study was to demonstrate the functional significance of GALP on lipid metabolism in the liver. Mice were fed a high fat diet to cause diet-induced obesity (DIO) and then administered GALP intranasally for 2 weeks (experimental), or vehicle (control)...

Calcitonin gene-related peptide (CGRP) is a bioactive peptide produced by alternative splicing of the primary transcript of the calcitonin/CGRP gene. CGRP is largely distributed in the cardiovascular and nervous systems, where it acts as a regulatory factor. CGRP is also expressed in organs and tissues involved in metabolic regulation, including white adipose tissue (WAT), where its function is largely unknown. In this study, we examined the effects of endogenous CGRP on metabolic function. When we administered a high-fat diet to CGRP knockout (CGRP-/-) and wild-type (WT) mice for 10 weeks, we observed that food intake did not differ between the two groups, but body weight and visceral fat weight were significantly lower in CGRP-/- mice...

Bombesin receptor subtype 3 (BRS-3) is an orphan G-protein-coupled receptor. Based on the obese phenotype of male BRS-3-deficient mice, BRS-3 has been considered an attractive target for obesity treatment. Here, we developed a novel selective BRS-3 agonist (Compound-A) and evaluated its anti-obesity effects. Compound-A showed anorectic effects and enhanced energy expenditure in diet-induced obese (DIO)-F344 rats. Moreover, repeated oral administration of Compound-A for 7 days resulted in a significant body weight reduction in DIO-F344 rats...

Loss-of-function mutations in the X-linked immunoglobulin superfamily, member 1 (IGSF1) gene cause central hypothyroidism. IGSF1 is a transmembrane glycoprotein of unknown function expressed in TSH-producing thyrotrope cells of the anterior pituitary gland. The protein is co-translationally cleaved, with only its C-terminal domain (CTD) being trafficked to the plasma membrane. Most intragenic IGSF1 mutations in humans map to the CTD. Here, we used CRISPR-Cas9 to introduce a loss-of-function mutation into the IGSF1-CTD in mice...

Three hundred one-day-old male broiler chickens (Ross-308) were fed corn-soybean basal diets containing non-starch polysaccharide (NSP) enzyme and different levels of acid protease from 1 to 42 days of age to investigate the effects of exogenous enzymes on growth performance, digestive function, activity of endogenous digestive enzymes in the pancreas and mRNA expression of pancreatic digestive enzymes. For days 1-42, compared to the control chickens, average daily feed intake (ADFI) and average daily gain (ADG) were significantly enhanced by the addition of NSP enzyme in combination with protease supplementation at 40 or 80 mg/kg (p<0...

Developmental programming is influenced by perinatal nutrition and it has long-lasting impacts on adult metabolism in the offspring. In particular, maternal high fat diet has been associated with increased risk of obesity and metabolic disorders during adulthood in the descendants. These effects may be due to the effects of the high fat diet on the development of the systems that regulate food intake and energy balance in the offspring hypothalamus. The arcuate nucleus (ARC) may be a particularly sensitive region to it as this nucleus contains the POMC and AgRP/NPY neurons that integrate the melanocortin system...

Endoplasmic reticulum (ER) stress caused by accumulation of misfolded proteins is observed in several kinds of diseases. Since ER stress is reported to be involved in the progression of non-alcoholic steatohepatitis (NASH), highly sensitive and simple measurement methods are required for research into developing novel therapy for NASH. To investigate the involvement of ER stress in NASH pathogenesis in a mouse model, an assay for liver ER stress was developed using ER stress activated indicator-luciferase (ERAI-Luc) mice...

Obesity and associated type 2 diabetes (T2D) are important risk factors for infection following orthopaedic implant surgery. Staphylococcus aureus, the most common pathogen in bone infections, adapts to multiple environments to survive and evade host immune responses. Whether adaptation of S. aureus to the unique environment of the obese/T2D host accounts for its increased virulence and persistence in this population is unknown. Thus, we assessed implant-associated osteomyelitis in normal versus high fat-diet obese/T2D mice and found that S...

Maternal malnutrition lead to the incidence of metabolic diseases in offspring. The purpose of this project was to exam whether maternal low chromium could disturb normal lipid metabolism in offspring, altering adipose cell differentiation and leading the incidence of lipid metabolism diseases, including metabolic syndrome and obesity. Female C57BL mice were given a control diet (CD) or a low chromium diet (LCD) during the gestational and lactation periods. After weaning, offspring was fed with CD or LCD. The female offspring were assessed at 32 weeks of age...

Epidemiological studies have demonstrated a close association of type 2 diabetes and hepatocellular carcinoma (HCC). Exenatide (Ex-4), a potent diabetes drug targeting glucagon-like peptide-1 receptor (GLP-1R), is protective against non-alcoholic fatty liver disease (NAFLD). However, the Ex-4 function and GLP-1R status have yet been explored in HCC. Herein we investigated the effect of Ex-4 in diethylnitrosamine (DEN)-treated mice consuming control or high-fat high-carbohydrate diet. Administration of Ex-4 significantly improved obesity-induced hyperglycemia and hyperlipidemia and reduced HCC multiplicity in obese DEN-treated mice, in which suppressed proliferation and induced apoptosis were confined to tumor cells...

Many fibre sources can help the adaptation of piglets at weaning, improving the growth. In this study, the effects of a dietary crude fibre concentrate (CFC) on piglet's growth was investigated. From 31 to 51 days of age, 108 weaned piglets (D×(Lw×L)), had access to two isofibrous, isoenergetic and isonitrogenous diets, supplemented with 1% of CFC (CFC group) or not (control (CON) group). From days 52 to 64 all piglets received the same starter diet. During the dietary treatment period the CFC group showed higher average daily gain, average daily feed intake and feed efficiency (P<0...
