Obesity is a significant risk factor for chronic diseases. The effect of ethanol extract from germinated Keunnunjami, blackish-purple rice with a giant embryo, compare to ordinary brown rice, on the body weight and lipid and glucose metabolism in high-fat diet-fed mice was analyzed. Mice were fed with a high-fat diet-fed for 3 weeks and then orally administered with either distilled water (HF) or extract (0.25%, w / w ) from brown, germinated brown, Keunnunjami, and germinated Keunnunjami rice for 4 weeks. Control mice were fed with a normal diet and orally administered with distilled water. The HF group showed markedly higher body weight and triglyceride, cholesterol, fatty acid, glucose, and insulin levels than the control group. However, the oral administration of rice extracts ameliorated this high-fat diet-induced obesity, hyperlipidemia, and hypoglycemia through the modulation of adipokine production, lipogenic and glucose-regulating enzyme activities, and mRNA expression of genes associated with lipid and glucose metabolism. The germinated Keunnunjami extract exhibited greater hypolipidemic, hypoglycemic, and body weight-lowering effects than the other rice extracts. The results demonstrated that germination could further enhance the physiological properties of rice and that germinated Keunnunjami extract has a strong therapeutic potential against high-fat diet-induced obesity, hyperlipidemia, and hyperglycemia.

In the present study, the methanolic extract of Moringa oleifera leaves (MEMOL) was evaluated for antiobesity activity in rats. The antiobesity potential of MEMOL was studied against high fat diet-induced obesity (HFD) in rats. In this study, chronic administration of HFD in rats produced hypercholesterolemia (116.2 ± 0.27 mg/dL), which led to an increase in the body weight (225 gr), total cholesterol, triglycerides (263.0 ± 4.69 mg/dL), and attenuation in the levels of HDL (34.51 ± 2.20 mg/dL) as well as changes in body temperature of animals. Treatment of obese rats with MEMOL for 49 days resulted in a significant (P<0.001) change in body weight, total cholesterol, triglycerides, and LDL level along with a significant (P<0.001) increase in body temperature as compared to the HFD-induced obesity. MEMOL treated rats also showed a significant decrease in the level of liver biomarkers, organ weight, and blood glucose level. Further, rats treated with MEMOL (200 mg and 400 mg/kg) show reduced atherogenic index (1.7 ± 0.6 and 0.87 ± 0.76). The results indicate that the rats treated with Moringa oleifera (MO) have significantly attenuated the body weight without any change in the feed intake and also elicited significant thermogenic effect and to act as hypolipidemic and thermogenic property in obesity related disorders.

High-fat diet (HFD) is a major problem causing neuronal damage. Thymoquinone (TQ) could regulate oxidative stress and the inflammatory process. Hence, the present study elucidated the significant role of TQ on oxidative stress, inflammation, as well as morphological changes in the cerebellum of rats with HFD. Rats were divided into three groups as (1) control, (2) saturated HFD for eight weeks and (3) HFD supplementation (four weeks) followed by TQ 300 mg/kg/day treated (four weeks). After treatment, blood samples were collected to measure oxidative stress markers glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), and inflammatory cytokines. Furthermore, neuronal morphological changes were also observed in the cerebellum of the rats. HFD rats show higher body weight (286.5 ± 7.4 g) as compared with the control group (224.67 ± 1.78 g). TQ treatment significantly (p < 0.05) lowered the body weight (225.83 ± 13.15 g). TQ produced a significant (p < 0.05) reduction in cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). The antioxidative enzymes significantly reduced in HFD rats (GSH, 1.46 ± 0.36 mol/L and SOD, 99.13 ± 5.41 µmol/mL) as compared with the control group (GSH, 6.25 ± 0.36 mol/L and SOD, 159.67 ± 10.67 µmol/mL). MDA was increased significantly in HFD rats (2.05 ± 0.25 nmol/L) compared to the control group (0.695 ± 0.11 nmol/L). Surprisingly, treatment with TQ could improve the level of GSH, MDA, and SOD. TQ treatment significantly (p < 0.05) reduced the inflammatory markers as compared with HFD alone. TQ treatment minimizes neuronal damage as well as reduces inflammation and improves antioxidant enzymes. TQ can be considered as a promising agent in preventing the neuronal morphological changes in the cerebellum of obese populations.

Diabetes was induced by intraperitoneal injection of streptozotocin (35 mg/kg bw) in all rats of five groups after being fed for 2 weeks high-fat diet. Type 2 diabeticNerium-oleander-(NO-) administered groups received the NO distillate at a dose of 3.75, 37.5, and 375 μg/0.5 mL of distilled water (NO-0.1, NO-1, NO-10, resp.); positive control group had 0.6 mg glibenclamide/kg bw/d by gavage daily for 12 weeks. Type 2 diabetic negative control group had no treatment. NO distillate administration reduced fasting blood glucose, HbA1c, insulin resistance, total cholesterol, low density lipoprotein, atherogenic index, triglyceride-HDL ratio, insulin, and leptin levels. Improved beta cell function and HDL concentration were observed by NO usage. HDL percentage in total cholesterol of all NO groups was similar to healthy control. NO-10 distillate enhanced mRNA expressions of peroxisome proliferator-activated-receptor- (PPAR-)α,β, andγin adipose tissue and PPAR-α–γin liver. The findings from bothin vivoandin vitrostudies suggest that the considerable beneficial effect of NO distillate administration at a dose of 375 μg/0.5 mL of distilled water may offer new approaches to treatment strategies that target both fat and glucose metabolism in type 2 diabetes.

Previous studies have shown that agonists of GPR17 stimulate, while antagonists inhibit feeding. However, whole body knockout of GPR17 in mice of the C57Bl/6 strain did not affect energy balance, whereas selective knockout in oligodendrocytes or pro-opiomelanocortin neurons provided protection from high fat diet-induced obesity and impaired glucose homeostasis. We reasoned that whole body knockout of GPR17 in mice of the 129 strain might elicit more marked effects because the 129 strain is more susceptible than the C57Bl/6 strain to increased sympathetic activity and less susceptible to high fat diet-induced obesity. Consistent with this hypothesis, compared to wild-type mice, and when fed on either a chow or a high fat diet, GPR17 -/- mice of the 129 strain displayed increased expression of uncoupling protein-1 in white adipose tissue, lower body weight and fat content, reduced plasma leptin, non-esterified fatty acids and triglycerides, and resistance to high fat diet-induced glucose intolerance. Not only energy expenditure, but also energy intake was raised. Administration of leptin did not suppress the increased food intake in GPR17 -/- mice of the 129 strain, whereas it did suppress food intake in GPR17 +/+ mice. The only difference between GPR17 +/- and GPR17 +/+ mice of the C57Bl/6 strain was that the body weight of the GPR17 -/- mice was lower than that of the GPR17 +/+ mice when the mice were fed on a standard chow diet. We propose that the absence of GPR17 raises sympathetic activity in mice of the 129 strain in response to a low plasma fuel supply, and that the consequent loss of body fat is partly mitigated by increased energy intake.

Diet Induced Obesity

Obesity in itself is a disease condition and a major risk factor in the development of hypertension, dyslipidemia, and hyperglycemia. Therefore, successful strategies for improving obesity and related metabolic risk factors are needed. Role of renin-angiotensin system (RAS) has been implicated in obesity and metabolic dysfunction. Recently, we have shown that AT2R knock-out in female mice caused a greater body weight gain and hyperinsulimia in response to high fat diet (HFD). In the present study, we hypothesize that AT2R activation rescues diet-induced obesity in females. To test this hypothesis, we injected AT2R non-peptide agonist C21 (0.3mg/kg/day i.p) in C57BL6 female mice on HFD for 12 weeks. C21-treatment did not affect the HFD calorie intake (HFD: 937±18 Kcal; C21HFD: 886±37 Kcal) but caused lesser body weight gain compared to control (HFD: 4.4± 0.4g; C21HFD: 3.06± 0.4g). Similar to the body weight gain pattern, gonadal fat weight and adipocyte size were decreased significantly in C21-treated mice on HFD compared to control HFD group (HFD: 4.4± 0.4 g; C21 HFD: 3.06± 0.4g) and (HFD: 6404±161.6μm2 ; C21HFD: 3874±103.2μm2 ) respectively. Moreover, the C21-treated females on HFD had lower levels of plasma insulin, improved glucose tolerance, and decreased plasma free fatty acids and hepatic triglycerides. Western blot revealed that phospho-Ser79-acetyl CoA carboxylase (p-Ser79-ACC-1) was reduced, an index of increased lipogenic activity and decreased β-oxidation process, in both adipose (Adi) and hepatic (Hep) tissues of HFD fed groups (Adi: 86% and Hep: 73% of 100% controls); C21-treatment revered the decrease in p-ser79-ACC-1 in Adi (104% of control) and caused an increase in Hep (122% of control) respectively. The HFD feeding lowered the estradiol level (ND: 38.8±2.6 vs HFD:11.3±1.2ng), which was modestly reversed by C21 treatment (C21HFD:17.4± 1.5ng) in HFD mice. Our results strongly suggest that stimulation of AT2R in female mice positively contribute, predominantly independent of estrogen, to rescue body weight gain and adipocyte size increase in response to HFD. We propose reduced lipogenesis and enhanced lipid β-oxidation as potential mechanisms linked to AT2R action in reducing obesity and its related metabolic disorders in females.

Obesity becomes a global epidemic nowadays. The high-fat diet is used as an alternative therapy for obesity. The optimal composition of a high-fat diet to reduce body weight is still unknown. This study aimed to determine which components of a high-fat diet can decrease body weight, visceral fat, and PPARG expression of visceral fat. This study was conducted at the Faculty of Veterinary Medicine, Universitas Airlangga, for three months by using a randomized post-test only control group design. Fifty male mice, 2-3 months old, 18-30 grams were adapted for one week given standard diet AIN93-M, then mice were divided into five groups, namely K1 (control group, 12% fat, 20% protein, 62% carbs); K2 (30% fat, 60% proteins, 0% carbs); K3 (45% fat, 45% protein, 0% carbs);  K4 (60% fat, 30% protein, 0% carbs); and K5 (75% fat, 15% protein, 0% carbs). Bodyweight was measured before and after treatment, then the visceral fat and PPARG expressions were evaluated. Statistical comparisons were performed using Statistical Package for the Social Sciences (SPSS) software. After treatment, there were forty-three mice. The body weight and visceral fat weight of the mice with a high-fat diet were decreased. The most significant changes in body weight were in K4 with -9,60 ± 3,806 grams reduction. The bodyweight of mice in K5, slightly increased than K2-K4. This could be caused by the hormesis phenomenon. PPARG expressions decreased in groups with a high-fat diet but increased in K5. The composition of a high-fat diet in group K4 was the most optimal to decrease the body weight, visceral fat, and PPARG expressions in mice

Erythropoietin (Epo) is a pleotropic cytokine with several nonhematopoietic tissue effects. High-dose Epo treatment-mediated effects on body weight, fat mass and glucose tolerance have recently been reported, thus extending its pleotropic effects to fat and glucose metabolism. However, the exact dose range of Epo treatment required for such effects remains unidentified to date. We investigated Epo dosage effect (up to 1000 U/kg) on hematocrit, body weight, body composition, glucose metabolism, food intake, and physical activity, during high-fat diet-induced obesity. We report that Epo doses (1000, 600, 300, and 150 U/kg) significantly reduced body weight gain and fat mass, while, only Epo doses of 300 U/kg and higher significantly affected glucose tolerance. None of the tested Epo doses showed any detectable effects on food intake, and only 1000 U/kg dose significantly increased physical activity, suggesting that these parameters may only be partially responsible for the metabolic effects of Epo treatment.

Objective: To evaluate the effect of vitamin E on the level of oxidative stress in diet-induced obese Sprague-Dawley rats. Methods: Thirty weaning male rats were placed into three groups with 10 animals each: a control group with normal chow, a diet-induced obesity group (DIO) with high-fat diet, and an intervention group with high-fat diet supplemented with vitamin E (VE, 350 mg/kg). Blood and adipose tissue were collected from rats after 10 weeks. Biomarkers of oxidative stress were detected for plasma 8-epi-prostaglandin- F2α (8-epi-PGF2α), thiobarbituric acid-reactive substances (TBARS), total anti-oxidative capacity (TAOC), α-tocopherol, superoxide dismutase (SOD) activity, and glutathione peroxidase activity (GPx). Lipid and glucose metabolism parameters such as plasma glucose, insulin, and triacylglycerol (TG) were also analyzed. Results: After 10 weeks, all obese rats (both the DIO and VE groups) had higher plasma 8-epi-PGF2α and TBARS levels than the controls. Their plasma-adjusted α-tocopherol, SOD, and GPx activities were lower than the control levels but insulin was higher (p<0.01). The VE intervention increased plasma SOD, GPx, and T-AOC, and decreased 8-epi-PGF2α (p<0.05). VE intervention also decreased plasma glucose, insulin, and TG levels (p<0.05). Conclusions: Increased oxidative stress could be an important target for the prevention of obesity-related diseases. Vitamin E has moderate effects for improvement of oxidative stress status and glucose metabolism in the animal model of diet-induced obesity.

Background: Currently, obesity is a global health challenge due to its increasing prevalence and associated health risk. It is associated with various metabolic diseases, including diabetes, hypertension, cardiovascular disease, stroke, certain forms of cancer, and non-alcoholic liver diseases (NAFLD). Objective: The aim of this study to evaluate the effects of polyphenol enriched herbal complex (Rubus crataegifolius/ellagic acid, Crataegus pinnatifida Bunge/vitexin, chlorogenic acid, Cinnamomum cassiaa/cinnamic acid) on obesity and obesity induced NAFLD in the high-fat diet (HFD)-induced obese mouse model. Methods: Obesity was induced in male C57BL/6 mice using HFD. After 8 weeks, the mice were treated with HFD+ plants extract for 8 weeks. Body weight, food intake weekly, and blood sugar level were measured. After sacrifice, changes in the treated group’s liver weight, fat weight, serum biochemical parameters, hormone levels, and enzyme levels were measured. For histological analysis, tissues were stained with hematoxylin-eosin (H&E) and Oil Red-O. Results: Our results showed that the herbal complex ameliorated body weight and liver weight gain, and decreased total body fat in HFD-fed animals. Post prandial blood glucose (PBG) and fasting blood glucose (FBG) were lower in the herbal complex-treated group than in the HFD control group. Additionally, herbal formulation treatment significantly increased HDL levels in serum and decreased TC, TG, AST, ALT, deposition of fat droplets in the liver, and intima media thickness (IMT) in the aorta. Herbal complex increased serum adiponectin and decreased serum leptin. Herbal complex also increased carnitine palmityl transferase (CPT) activity and significantly decreased enzyme activity of beta-hydroxy beta methyl glutamyl-CoA (HMG-CoA) reductase, and fatty acid synthase (FAS). Conclusions: The results of this study demonstrated that the herbal complex is an effective herbal formulation in the attenuation of obesity and obesity-induced metabolic dysfunction including NAFLD in HFD-induced mouse model.
