Environmental factors (e.g., malnutrition and physical inactivity) contribute largely to metabolic disorders including obesity, type 2 diabetes, cardiometabolic disease and nonalcoholic fatty liver diseases. The abnormalities in metabolic activity and pathways have been increasingly associated with altered DNA methylation, histone modification and noncoding RNAs, whereas lifestyle interventions targeting diet and physical activity can reverse the epigenetic and metabolic changes. Here we review recent evidence primarily from human studies that links DNA methylation reprogramming to metabolic derangements or improvements, with a focus on cross-tissue (e...

Dried plum (DP), a rich source of polyphenols has been shown to have bone-preserving properties in both animal models of osteoporosis and postmenopausal women. We evaluated if DP alleviated the destruction of joints in transgenic mice (TG) that overexpress human tumor necrosis factor (TNF), a genetic model of rheumatoid arthritis (RA). A four-week treatment of 20% DP diet in TG slowed the onset of arthritis and reduced bone erosions in the joints compared to TG on a regular diet. This was associated with fewer tartrate-resistant acid phosphatase (TRAP) positive cells, suggesting decreased osteoclastogenesis...

Chrononutrition is the science of nutrition based on chronobiology. Numerous epidemiological studies have shown that fish oil (FO) reduces the risk of cardiovascular events through various actions such as lowering triglycerides. The present study aimed to determine the time of day when the hypertriglyceridemia-decreasing ability of FO is optimal in mice. A high-fructose diet (HFrD) that induces hyperlipidemia in mice was replaced with the same diet containing 4% FO (HFrD-4% FO) at different times of the day for 2 weeks as described below...

Peak bone mass (PBM) achieved at adulthood is a strong determinant of future onset of osteoporosis, and maximizing it is one of the strategies to combat the disease. Recently, pomegranate seed oil (PSO) has been shown to have bone-sparing effect in ovariectomized mice. However, its effect on growing skeleton and its molecular mechanism remain unclear. In the present study, we evaluated the effect of PSO on PBM in growing rats and associated mechanism of action. PSO was given at various doses to 21-day-old growing rats for 90 days by oral gavage...

Early life inadequate nutrition triggers developmental adaptations and adult chronic disease. Maternal high-fat (HF) diet promotes visceral obesity and hypothalamic leptin resistance in male rat offspring at weaning and adulthood. Obesity is related to over active endocannabinoid system (ECS). The ECS consists mainly of endogenous ligands, cannabinoid receptors (CB1 and CB2), and the enzymes fatty acid anandamide hydrolase (FAAH) and monoacylglycerol lipase (MAGL). We hypothesized that perinatal maternal HF diet would regulate offspring ECS in hypothalamus and brown adipose tissue (BAT) at birth, prior to visceral obesity development, and program food preference and energy expenditure of adult offspring...

Proteasomes are known to degrade proteins involved in various processes like metabolism, signal transduction, cell-cycle regulation, inflammation, and apoptosis. Evidence showed that protein degradation has a strong influence on developing neurons as well as synaptic plasticity. Here, we have shown that sulforaphane (SFN) could prevent the deleterious effects of postnatal proteasomal inhibition on spatial reference and working memory of adult mice. One day old Balb/c mice received intracerebroventricular injections of MG132 and SFN...

Obesity is well documented as a risk factor for developing breast cancer, especially in postmenopausal women. Adipose tissue in the breast under obese conditions induces inflammation by increasing macrophage infiltration and pro-inflammatory cytokines that in turn up-regulates genes and signaling pathways, resulting in increased inflammation, cell proliferation and tumor growth in the breast. Due to their potent anti-inflammatory effects, n-3 polyunsaturated fatty acids (n-3 PUFA) are a promising and safe dietary intervention in reducing breast cancer risk...

Olive oil vascular benefits have been attributed to hydroxytyrosol (HT). However, HT biological actions are still debated because it is extensively metabolized into glucuronides (GCs). The aim of this study was to test HT and GC vasculoprotective effects and the underlying mechanisms using aorta rings from 8-week-old male Wistar rats. In the absence of oxidative stress, incubation with 100 μM HT or GC for 5 min did not exert any vasorelaxing effect and did not influence the vascular function. Conversely, in condition of oxidative stress [upon incubation with 500 μM tert-butylhydroperoxide (t-BHP) for 30 min], preincubation with HT or GC improved acetylcholine-induced vasorelaxation compared with untreated samples (no t-BHP)...

At present, high-density lipoprotein (HDL) function is thought to be more relevant than HDL cholesterol quantity. Consumption of olive oil phenolic compounds (PCs) has beneficial effects on HDL-related markers. Enriched food with complementary antioxidants could be a suitable option to obtain additional protective effects. Our aim was to ascertain whether virgin olive oils (VOOs) enriched with (a) their own PC (FVOO) and (b) their own PC plus complementary ones from thyme (FVOOT) could improve HDL status and function...

Chemotherapy is essential to most patients with gastric cancer and the anticancer drug, irinotecan (CPT-11), and its metabolite, SN-38, an inhibitor of DNA topoisomerase I, are first-line chemotherapies for gastric cancer. Quercetin, a flavonoid that is widely found in various vegetables and fruits, has the ability to potentiate the efficacy of anticancer drugs. The purpose of this study was to investigate the therapeutic effect of quercetin combined with irinotecan/SN-38 in the AGS human gastric cancer cell line in vitro and in vivo...

Atherosclerosis is an age-associated disease; however, diabetic atherosclerosis has higher severity beyond age range for accumulative premature senescent cells in diabetes. Recent findings suggest that rutin, a flavonoid, has potential benefits for diabetic individuals. This study was designed to evaluate the effects of rutin on premature senescence and atherosclerosis. Apolipoprotein E knockout mice exhibiting insulin resistance after 6 weeks of high-fat diet were administered with a low dose of streptozotocin (STZ) to induce diabetes...

In hypercholesterolemic pregnancies, the maternal environment is characterized by excessive levels of atherogenic lipids that may increase cardiovascular disease risk in mothers and their offspring. We examined the influence of maternal hypercholesterolemia and phytosterol (PS) intervention on the concentration and metabolism of oxysterols, bioactive oxygenated cholesterol derivatives that regulate arterial health and lesion progression, in mothers and their newly weaned offspring. Twenty-one female apoE(-/-) mice were randomly assigned to three different diets throughout gestation and lactation: (1) chow, (2) high cholesterol (CH; 0...

The burden and morbidity of environmental nephrosis is increasing globally. Atrazine (ATR) and degradation products in the environment are considered key determinants of nephrosis. However, the lack of highly effective treatments for environmental nephrosis creates an urgent need to better understand the preventive strategies and mechanisms. This study aimed to highlight the mechanism of ATR-induced environmental nephrosis and the chemoprotective potential of lycopene (LYC) against the renal injury and nephrosis...

Insulin resistance induced by a high-fructose diet has been associated to hypertension and renal damage. The aim of this work was to assess alterations in the urinary L-dopa/dopamine ratio over three time periods in rats with insulin resistance induced by fructose overload and its correlation with blood pressure levels and the presence of microalbuminuria and reduced nephrin expression as markers of renal structural damage. Male Sprague-Dawley rats were randomly divided into six groups: control (C) (C4, C8 and C12) with tap water to drink and fructose-overloaded (FO) rats (FO4, FO8 and FO12) with a fructose solution (10% w/v) to drink for 4, 8 and 12 weeks...

The current system of food production is linked to both the increasing prevalence of chronic disease and the deterioration of the environment, and thereby calls for novel ways of producing nutritious foods in a sustainable manner. In the "longevity village" of Bama, China, we have identified two plant foods, hemp seed and bitter vegetable (Sonchus oleraceus), that are commonly consumed by its residents and grow abundantly in unfarmed land without fertilizers or pesticides. Here, we show that a diet composed of these two foods (the "HB diet") provides a sufficient variety of nutrients and confers significant health benefits...

Green tea (GT) is a widely consumed beverage with health benefits, including antiobesity effects; however, the efficacy of GT on lipid levels associated with obesity is not clearly understood. Here, we examined the impact of GT consumption on lipid metabolism in the livers of high-fat diet (HFD)-induced obese mice. We performed lipid profiling using ultraperformance liquid chromatography quadrupole time-of-flight mass spectrometry in C57BL/6J mice fed a normal diet (ND), HFD and HFD with GT for 12 weeks. The partial least squares discriminant analysis score plot showed a difference among the groups and revealed that the levels of several lipid metabolites were altered in mice fed HFD with GT...

Phosphatidylcholines (PCs), a major class of human plasma phospholipids, are composed of highly diverse fatty acids. Because the dietary carbohydrate-fat ratio alters the hepatic fatty acid metabolism, plasma fatty acids that bind PCs, which are secreted as lipoproteins from the liver, may be affected by long-term consumption of a high-carbohydrate diet or a high-fat diet. Therefore, in this study, we profiled the plasma PC species comprehensively in formulated dieting conditions to identify those phospholipid molecules that reflect the dietary carbohydrate-fat ratio...

Persistent intestinal inflammation severely impairs intestinal integrity resulting in inflammatory bowel disease. Red raspberries (RB) are a rich source of bioactive compounds; their beneficial effect on the colitis protection was evaluated in the current study using a dextran sulfate sodium (DSS)-induced acute colitis mouse model. Six-week-old mice were fed a standard rodent research diet supplemented with RB (0 or 5% w/w, n=20 each group) for 6 weeks. At the 4th week of dietary treatment, approximately half of mice in each dietary group (n=12 each group) were subjected to 2...
