Male C57BL/6J mice were used to determine the possible therapeutic effects of our previously described tart cherry extract in a chronic obesity mouse model on metabolic parameters, glucose tolerance, inflammatory mediators, and antioxidant capacity. The control group received standard mouse chow, and the high fat control group was switched to a high fat diet and tap water supplemented with 5% sucrose. The high fat + anthocyanin group received the high fat and sucrose diet, but received the anthocyanin-rich tart cherry extract dissolved in their drinking water. After six weeks, an oral glucose tolerance test was performed, and the water-soluble antioxidant capacity (ACW), superoxide dismutase (SOD) activity, and the plasma levels of insulin, C-peptide, leptin, IL-6, MCP-1, adiponectin and resistin were measured. The high fat diet increased body weight, reduced glucose tolerance, and caused an elevation in leptin, IL-6, MCP-1, and resistin levels. Furthermore, antioxidant capacity was decreased with a significant elevation of SOD activity. Anthocyanin treatment failed to reverse the effects of the high fat diet on body weight and glucose tolerance, but significantly reduced the leptin and IL-6 levels. The tart cherry extract also made a significant enhancement in antioxidant capacity and SOD activity. Our results show that chronic anthocyanin intake has a potential to enhance redox status and alleviate inflammation associated with 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.

Obesity increases risk of Alzheimer’s Disease (AD). A high fat diet (HFD) can lead to amyloidosis and amyloid beta (Aβ) accumulation, which are hallmarks of AD. In this study, protective effects of the ethyl acetate fraction of Acer okamotoanum (EAO) and isoquercitrin were evaluated on obesity and amyloidosis in the HFD- and Aβ-induced mouse model. To induce obesity and AD by HFD and Aβ, mice were provided with HFD for 10 weeks and were intracerebroventricularly injected with Aβ25–35. For four weeks, 100 and 10 mg/kg/day of EAO and isoquercitrin, respectively, were administered orally. Administration of EAO and isoquercitrin significantly decreased body weight in HFD and Aβ-injected mice. Additionally, EAO- and isoquercitrin-administered groups attenuated abnormal adipokines release via a decrease in leptin and an increase in adiponectin levels compared with the control group. Furthermore, HFD and Aβ-injected mice had damaged liver tissues, but EAO- and isoquercitrin-administered groups attenuated liver damage. Moreover, administration of EAO and isoquercitrin groups down-regulated amyloidosis-related proteins in the brain such as β-secretase, presenilin (PS)-1 and PS-2 compared with HFD and Aβ-injected mice. This study indicated that EAO and isoquercitrin attenuated HFD and Aβ-induced obesity and amyloidosis, suggesting that they could be effective in preventing and treating both obesity and AD.

Abstract Objectives The objective of this study was to investigate the anti-dyslipidemia effects of tart cherry supplementation on body weight and lipid profiles of serum in High Fat Diet-Fed Mice. Methods After 2 weeks of adaptation period, forty 7-week-old male C57BL/6J mice were randomly divided into 4 groups (n = 10 per group): normal diet control group (ND), high fat diet control group (HF), HF group fed with 1% tart cherry powder (LC, low dose of cherry), HF group fed with 5% tart cherry powder (HC, high dose of cherry). After 12 weeks of tart cherry dietary supplementation, serum triglyceride (TG), total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) were analyzed. Results Final body weight of LC (1%) and HC (5%) was significantly lower than that of HF control group (P < 0.001). Also, body weight gained in LC (1%) and HC (5%) was significantly lower than HF control group (P < 0.001). In serum, triglyceride (TG) and total cholesterol (TC) levels were significantly lower in HC (5%) group compared to HF control group (P < 0.05, P < 0.001, respectively). Serum HDL-cholesterol levels in LC (1%) and HC (5%) groups was significantly higher than HF control group (P < 0.05). Conclusions Tart cherry dietary supplementation may have an anti-dyslipidemia effect in high fat diet-fed mice by lowering body weight gain and modulating serum cholesterol levels. Further analysis of AMPK-regulated fatty acid oxidation biomarkers are under investigation. Funding Sources This study received no external funding.

The aim of this study was to determine the comparative effects of EA (EA) on the CV12, ST36 and ST40 to weight gain prevention over the short-term regulation of energy balance. The study was conducted with a completely randomized design. Rats were divided into five groups: negative control group (no treatment, n=5), positive control (sham EA/back, n=5), EA CV 12 (n=6), EA ST 36 (n=6) and EA ST 40 (n=7). Rats were exposed to high-fat diet for two weeks and EA was simultaneously performed once daily, five days a week for two weeks with 2 Hz, for 10 minutes with continuous wave. Body weight, BMI, front limb circumference and rear were measured during study. Levels of blood glucose, cholesterol, triglycerides, LDL and HDL were measured at the end of the study; which reflects the short-term regulation of energy homeostasis. For weight loss, EA CV12, ST36 and ST40 group have lost weight significantly compared to the negative and positive control group. The ST40 group has a significant decrease than ST36 and CV12. The most significant decrease in BMI found in the ST40 group. EA did not affect blood glucose levels, but modulated blood lipid profile. In ST 40 group there was a significant decrease in cholesterol, LDL and triglycerides. EA at point ST 40 is potential in preventing increased body weight and BMI in rats exposed to high-fat diet compared to the CV 12 and ST 36. ST 40 is a point with a potential of lowering LDL and triglycerides serum so that it can play a role in the short term regulation of energy homeostasis but also in the prevention of dyslipidemia.

Pyrin Domain

NLR family, pyrin domain-containing 3 (NLRP3) is a pattern recognition receptor responsible for perpetuating an inflammatory response through production of pro-inflammatory cytokines IL-1β and IL-18. It has been implicated in the sustained inflammatory response in obesity and multiple cardiovascular disease conditions. In order to investigate NLRP3 as a potential therapeutic target in metabolic syndrome, C57BL/6 wild-type (WT) and NLRP3 knockout (NLRP3-\-) mice were fed a normal diet (ND; 12% fat chow) or a high fat diet (HFD; 45% fat chow) for 5 months. At 5 months, echocardiography and glucose tolerance tests (GTTs) were performed. Cardiac function assessed by fractional shortening (FS) was significantly impaired by HFD feeding in the WT group (0.335 HFD vs. 0.456 ND; p<0.05) but not in the NLRP3-\- (0.449 HFD vs. 0.492 ND; p>0.05). FS was higher in NLRP3-\-HFD than in WT-HFD (p<0.05). Two-dimensional analysis shows the FS difference between NLRP3-\-HFD and WT-HFD was primarily explained by the difference in left ventricular end-systolic dimension (0.2716 cm WT vs. 0.1883 cm NLRP3-\-; p<0.05). Glucose tolerance measured by area under the curve (AUC) was significantly impaired by HFD feeding for both WT (23183 ND vs. 57298 HFD; p<0.001) and NLRP3-\- (23197 ND vs. 44626 HFD; p<0.001), but significantly better in the NLRP3-\-HFD than in WT-HFD (p<0.01). HFD feeding increased fasting blood glucose (FBG) for both WT (97.7 mg . dl -1 ND vs. 164.7 mg . dl -1 HFD; p<0.01) and NLRP3-\- (80.50 mg . dl -1 ND vs. 108.8 mg . dl -1 HFD; p<0.05), but significantly less in NLRP3-\- mice (NLRP3-\- vs. WT; p<0.05). For GTTs, body weight was significantly higher in the WT than NLRP3-\- fed HFD (47.93 g vs. 36.5 g; p<0.001). Body weight explained 92% of variation in glucose tolerance (p<0.0001) and 69% of variation in fasting blood glucose (p<0.0001). WT-HFD averaged 1.31X heavier than NLRP3-\-HFD, while the AUC for the IGTT was 1.28X larger for the WT-HFD than NLRP3-\-HFD. Body weights were not significantly different between genotypes at the time of echo. The results suggest that knockout of NLRP3 may be protective against HFD induced cardiovascular dysfunction. A protective effect on glucose tolerance is not strongly supported.

Abstract Objectives Patchouli alcohol is a sesquiterpene alcohol found in Pogostemon cablin. Recently, we observed that patchouli alcohol reduced lipid accumulation in differentiated 3T3-L1 adipocytes and increased glucose uptake in differentiated C2C12 myocytes. This study was designed to investigate anti-obese and anti-diabetic activities of patchouli alcohol using high fat diet-induced obese mouse model. Methods Forty-eight 5-week old C57BL/6 J male mice were assigned into four groups and fed with 1) normal diet (control), 2) high fat diet, 3) high fat diet with gavaging 25 mg of patchouli alcohol/kg body weight and 4) high fat diet with gavaging 50 mg of patchouli alcohol/kg body weight. High fat diet or control diets were provided to each treatment group for four weeks and then different doses of patchouli alcohol (0, 25 or 50 mg/kg body weight) was orally administered for following 8 weeks with the diet. At age of week 17, all animals were sacrificed, fat tissues were collected, and tissue weight was measured. In addition, twenty C57BL/6 J male mice were assigned into the same treatment groups above. At the end of the 8 weeks (age of week 17), the mice were fasted for 12 h and the oral glucose tolerance test was performed after intraperitoneal injection of 2 g of anhydrous glucose/kg body weight. The blood was collected from tail at 0, 15, 30, 90 and 120 min after injection and blood glucose level was analyzed using glucose meter. Results Treatment of patchouli alcohol (50 mg/kg body weight) significantly reduced body weight and accumulation of body fat pads which was highly induced by feeding of high fat diet. An analysis of individual fat pad weights (expressed as mg weight of fat pad/g body weight) revealed a significant decrease of epididymal and retroperitoneal fat pad in patchouli alcohol-treated mice whereas brown adipose tissue were not significantly altered. And, slightly improved glucose tolerance was observed at 90 and 120 minutes after glucose injection in mice treated with patchouli alcohol (50 mg/kg body weight) compared to those fed with high fat diet alone. Conclusions We propose a potential use of patchouli alcohol as an anti-obesity compound in obese population. Funding Sources NIFA Hatch grant. Supporting Tables, Images and/or Graphs

Maternal high-fat diet consumption and obesity have been shown to program long-term obesity and lead to impaired glucose tolerance in offspring. Many rodent studies, however, use non-purified, cereal-based diets as the control for purified high-fat diets. In this study, primiparous ICR mice were fed purified control diet (10–11 kcal% from fat of lard or butter origin) and lard (45 or 60 kcal% fat) or butter (32 or 60 kcal% fat)-based high-fat diets for 4 weeks before mating, throughout pregnancy, and for 2 weeks of nursing. Before mating, female mice fed the 32 and 60% butter-based high-fat diets exhibited impaired glucose tolerance but those females fed the lard-based diets showed normal glucose disposal following a glucose challenge. High-fat diet consumption by female mice of all groups decreased lean to fat mass ratios during the 4th week of diet treatment compared with those mice consuming the 10–11% fat diets. All females were bred to male mice and pregnancy and offspring outcomes were monitored. The body weight of pups born to 45% lard-fed dams was significantly increased before weaning, but only female offspring born to 32% butter-fed dams exhibited long-term body weight increases. Offspring glucose tolerance and body composition were measured for at least 1 year. Minimal, if any, differences were observed in the offspring parameters. These results suggest that many variables should be considered when designing future high-fat diet feeding and maternal obesity studies in mice.

Abstract Background and Aims Obesity and its associated chronic inflammation in adipose tissue initiate insulin resistance, which is related to several pathologies including hypertension and atherosclerosis. Previous reports demonstrated that circulating hepatocyte growth factor (HGF) level was associated with obesity and type 2 diabetes. However, its precise role in obesity and related-pathology is unclear. Method In this experiment, cardiac-specific over-expression of human HGF in mice (HGF-Tg mice) which showed 4-5 times higher serum HGF levels than wild-type mice were used. We chose cardiac specific HGF overexpression, as other strain of HGF transgenic mice such as liver and kidney specific HGF overexpression mice develop cancer and cystic diseases, which are rare in the heart. In the present study, using HGF-Tg mice and anti-HGF neutralizing antibody (HGF-Ab), we explored the role of HGF in obese and insulin resistance induced by high fat diet (HFD) for 14 weeks (200 or 400ug/week). Results With normal chow diet (ND), there were no significant changes in body weight between WT and HGF-Tg mice. While body weight in wild-type mice fed with HFD for 14 weeks was significantly increased accompanied with insulin resistance, HGF-Tg mice prevented body weight gain and insulin resistance. Insulin resistance in obesity arises from the combination of altered functions of insulin target cells (e.g., liver, skeletal muscle, and adipose tissue) and the accumulation of macrophages that secrete pro-inflammatory mediators in adipose tissue. The accumulation of macrophages and elevated levels of inflammatory mediators in adipose tissue were significantly inhibited in HGF-Tg mice as compared to wild-type mice. In the gWAT, the mRNA levels of the mature macrophage marker F4/80, the chemoattractants, MCP-1 and CXCL2, and the inflammatory cytokines, such as TNF-α and iNOS, were significantly increased in WT mice fed with HFD. However, these levels were markedly reduced in HGF-Tg mice fed with HFD. Additionally, activation of Akt by insulin administration was significantly reduced in the gWAT SM, and liver by HFD; however, this activation was restored in HGF-Tg mice. Moreover, insulin-induced Akt signaling was decreased in HGF-Ab groups as compared to saline group under HFD condition. Importantly, HFD significantly increased the level of HGF mRNA by approximately 2 fold in gWAT, SM, and liver without changing cMet expression. All together, these data indicate that the HGF as one of the systemic gWAT, SM, and liver-derived growth factor plays a role in compensatory mechanism against insulin-resistance through the at least anti-inflammatory effect in adipose tissue. The HFD-induced obesity in wild-type mice treated with HGF-neutralizing antibody showed an exacerbated response to the glucose tolerance test. Conclusion HGF suppresses inflammation in adipose tissue induced by a high-fat diet, and as a result improves systemic insulin resistance. These gain-of-function and loss-of-function studies demonstrated that the elevated HGF level induced by HFD have protective role against obesity and insulin resistance.
