The incidence of obesity, which is closely associated with the gut microbiota and chronic inflammation, has rapidly increased in the past 40 years. Therefore, the probiotic-based modification of the intestinal microbiota composition has been developed as a strategy for the treatment of obesity. In this study, we selected four Bifidobacterium adolescentis strains isolated from the feces of newborn and elderly humans to investigate whether supplementation with B. adolescentis of various origins could alleviate obesity in mice. Male C57BL/6J mice fed a high-fat diet (HFD, 60% energy as fat) received one of the following 14-week interventions: (i) B. adolescentis N4_N3, (ii) B. adolescentis Z25, (iii) B. adolescentis 17_3, (iv) B. adolescentis 2016_7_2, and (v) phosphate-buffered saline. The metabolic parameters, thermogenesis, and immunity of all treated mice were measured. Cecal and colonic microbial profiles were determined by 16S rRNA gene sequencing. Intestinal concentrations of short-chain fatty acids (SCFAs) were measured by gas chromatography-mass spectrometry (GC-MS). The B. adolescentis strains isolated from the feces of elderly humans (B. adolescentis Z25, 17_3, and 2016_7_2) decreased the body weight or weight gain of mice, whilst the strain isolated from the newborn (B. adolescentis N4_N3) increased the body weight of mice. The B. adolescentis strains isolated from the elderly also increased serum leptin concentrations and induced the expression of thermogenesis- and lipid metabolism-related genes in brown adipose tissue. All the B. adolescentis strains alleviated inflammations in the spleen and brain and modified the cecal and colonic microbiota. Particularly, all strains reversed the HFD-induced depletion of Bifidobacterium and reduced the development of beta-lactam resistance. In addition, the B. adolescentis strains isolated from the elderly increased the relative abundances of potentially beneficial genera, such as Bacteroides, Parabacteroides, and Faecalibaculum. We speculate that such increased abundance of commensal bacteria may have mediated the alleviation of obesity, as B. adolescentis supplementation decreased the intestinal production of SCFAs, thereby reducing energy delivery to the host mice. Our results revealed that certain strains of B. adolescentis can alleviate obesity and modify the gut microbiota of mice. The tested strains of B. adolescentis showed different effects on lipid metabolism and immunity regulation, with these effects related to whether they had been isolated from the feces of newborn or elderly humans. This indicates that B. adolescentis from different sources may have disparate effects on host health possibly due to the transmission of origin-specific functions to the host.

Objective. To investigate the effects of acupuncture on metabolic health and gut microbiota dysbiosis in diet-induced abdominal obese model. Materials and Methods. Male Sprague-Dawley rats were randomly distributed into normal chow diet (NCD) group and high-fat diet (HFD) group. After 12 weeks of HFD feeding, an abdominal obese rat model was established. The abdominal obese rats were further assigned to acupuncture group (n=7) and nontreated HFD group (n=7). Acupuncture was applied to bilateral GB 26 of rats for 8 weeks. Subsequently, the body weight, waist circumference (WC), visceral fat mass, and liver weight were measured weekly in all rats. Metabolic parameters such as total cholesterol, triglyceride, alanine aminotransferase, aspartate transaminase, and blood glucose were measured by an automatic biochemical analyzer. The serum levels of insulin (INS) were determined using Rat INS ELISA Kit. Analysis of gut microbiota was carried out by 16S rRNA gene sequencing. Results. Acupuncture decreased the body weight, WC, and visceral adipose tissues of HFD-induced abdominal obese rats. In addition, insulin sensitivity, glucose homeostasis, and lipid metabolism were improved by this treatment. Furthermore, electroacupuncture effectively modified the composition of gut microbiota, mainly via decreasing Firmicutes/Bacteroidetes ratio and increasing Prevotella_9 abundance. Conclusions. Electroacupuncture can ameliorate abdominal obesity and prevent metabolic disorders in HFD-induced abdominal obese rats, via the modulation of gut microbiota.

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.

: Probiotic dark tea (PDT) is a novel kind of dark tea produced by fresh albino tea leaves and fermented with specific probiotics. Our study demonstrates that PDT can ameliorate high-fat diet-induced overweight and lipid metabolic disorders and shows no acute or subacute toxicity in Sprague-Dawley (SD) rats. Daily intragastric administration of 5% PDT infusion for 14 days caused no obvious effect on general physiological features and behaviors of rats. Oral administration of 1%, 2%, and 3% of PDT infusion for six weeks had no influence on the biochemistry and histopathology of rats’ organs and blood, as well as the body weight and ratios of organ/body weight. To investigate its anti-obesity activity, SD rats were randomly divided into four groups, treated with normal diet + water (Group I), high-fat diet + water (Group II), high-fat diet + 3% traditional dark tea infusion (Group III), high-fat diet + 3% PDT infusion (Group IV). After six weeks, the body weight, serum total triacylglycerol (TG) and serum total cholesterol (TC) levels of rats in Group II were significantly increased and the high-density lipoprotein cholesterol (HDL) levels were significantly decreased compared with those in the other three groups. Both traditional dark tea and PDT treatment effectively counteracted the adverse effect of a high-fat diet in SD rats. These results suggest that PDT could be applied for the prevention of obesity, which ameliorates overweight and lipid metabolic disorders and which shows no acute or subacute toxicity.

AbstractAberration in leptin expression is one of the most frequent features in the onset and progression of obesity, but the underlying mechanisms are still unclear and need to be clarified. This study investigated the effects of the absence of gut microbiota on body weight and the expression and promoter methylation of the leptin. Male C57 BL/6 J germ-free (GF) and conventional (CV) mice (aged 4–5 weeks) were fed either a normal-fat diet (NFD) or a high-fat diet (HFD) for 16 weeks. Six to eight mice from each group, at 15 weeks, were administered exogenous leptin for 7 d. Leptin expression and body weight gain in GF mice were increased by NFD with more CpG sites hypermethylated at the leptin promoter, whereas there was no change with HFD, compared with CV mice. Adipose or hepatic expression of genes associated with fat synthesis (Acc1, Fas and Srebp-1c), hydrolysis and oxidation (Atgl, Cpt1a, Cpt1c, Ppar-α and Pgc-1α) was lower, and hypothalamus expression of Pomc and Socs3 was higher in GF mice than levels in CV mice, particularly with NFD feeding. Exogenous leptin reduced body weight in both types of mice, with a greater effect on CV mice with NFD. Adipose Lep-R expression was up-regulated, and hepatic Fas and hypothalamic Socs3 were down-regulated in both types of mice. Expression of fat hydrolysis and oxidative genes (Atgl, Hsl, Cpt1a, Cpt1c, Ppar-α and Pgc-1α) was up-regulated in CV mice. Therefore, the effects of gut microbiota on the leptin expression and body weight were affected by dietary fat intake.

The effect of the extract of Ligustrum lucidum fruits (LFE) and its major secoiridoid (LFS), (8- E)-nüzhenide, on obesity was investigated using high fat-diet (HFD)-induced C58BL/6J obese mice. LFE and LFS were administered at the doses of 300 mg/kg and 30 mg/kg, respectively, for 6 weeks. The anti-obesity activity was evaluated by measuring body weight, epididymal fat and metabolic plasma parameters. On Day 42, the body weight of the LFS-treated group was significantly lower compared with the HFD-treated group. Body weight gain was also reduced by 23.2% and 32.0% in the LFE- and LFS-treated groups, respectively, compared with the HFD group. In addition, the weight of the epididymal fat in the mice was significantly decreased in the HFD+LFS group. The food efficiency ratios (FERs) of the HFD+LFE and HFD+LFS groups were also lower compared with the HFD group with the same food intake. Metabolic parameters that had increased in the HFD group were decreased in the HFD+LFE and HFD+LFS groups. In particular, the increased triglyceride values were significantly reduced in the HFD+LFS group. These results show that treatment with LFE and LFS decreased HFD-induced obesity, mainly by improving metabolic parameters, such as fats and triglycerides. Therefore, LFE and LFS have potential benefits in regulation of obesity.

Abstract Objectives The dietary fat content plays an important role in the regulation of chronic metabolic diseases such as obesity and type 2 diabetes. Here, we tested the impacts of triacylglycerol structure on the body weight gain and food intake of mice in a high-fat diet (HFD) setting. Methods Male C57/BL6J mice at 6 weeks old were fed one of the following three diets for 6 weeks, Teklad Rodent Diet chow diet (number 8640), the chow diet containing 36% (w/w) 1,2-Dipalmitoyl-3-oleoylglycerol (PPO), or the chow diet containing 36% (w/w) 1,3-Dipalmitoyl-2-oleoylglycerol (POP). Each group contained 9 mice, and their food intake and BW were measured daily. The mice were euthanized after 6 weeks (12 weeks old) for tissue sample collection. Results Both high HFD groups had significantly higher BW gain and caloric intakes than the chow diet group. Mice fed the POP diet had a lower percentage of BW gain and consumed less accumulated calories than those fed the PPO diet, as well as a significantly lower liver to BW ratio. Since week 4, the body BW rate of the POP group started to be lower than that of the PPO diet group. Conclusions TAG structures in an HFD setting affect the BW gain rate and obesity in mice. The different structures of fat added to affect the food intake and BW gain differently in an HFD setting. In the future, we would like to compare the changes of the hepatic lipogenesis enzyme in these mice. This will help us to understand how the triacylglycerol structures in the diet affect lipid metabolism in mice. Funding Sources Internal.
