An insidious increase in the incidence of obesity, insulin resistance, and hyperlipidemia has led to an epidemic of type 2 diabetes worldwide. Tinospora crispa (T. crispa) is a familiar plant traditionally used in herbal medicine for diabetes; however, the major active ingredients of this plant are still unclear. In this study, we identified the therapeutic effects of borapetoside E, a small molecule extracted from T. crispa, in high-fat-diet (HFD)-induced obesity in mice. The therapeutic effects of borapetoside E in HFD-induced obese mice were assessed physiologically, histologically, and biochemically following intraperitoneal injection...

The aim of this study was to explore the potential beneficial effects of linarin enriched Flos Chrysanthemi extract (Lin-extract) on nonalcoholic steatohepatitis (NASH) induced by high-fat high-cholesterol (HFHC) diet in rats. SD rats received normal diet, HFHC diet, or HFHC diet plus different doses of Lin-extract. The liver content of triglyceride and total cholesterol markedly increased in HFHC diet-fed model rats while middle and high dose of Lin-extract lowered liver cholesterol significantly. The expression of stearoyl-CoA desaturase (SCD1) was upregulated by HFHC diet and further elevated by high dose Lin-extract...

Non-alcoholic fatty liver disease (NAFLD) is a prevalent chronic liver disease. The incidence of NAFLD has increased steadily due to its close association with the global epidemic of obesity and type 2 diabetes. However, there is no effective pharmacological therapy approved for NAFLD. Farnesoid X receptor (FXR), a member of the nuclear receptor subfamily, plays important roles in maintaining the homeostasis of bile acids, glucose and lipids. FXR agonists have shown promise for the treatment of NAFLD. Here we report Altenusin (2076A), a natural non-steroidal fungal metabolite, as a novel selective agonist of FXR with an EC50 value of 3...

A diet containing a high n-3/n-6 polyunsaturated fatty acids (PUFA) ratio has cardioprotective properties. PUFAs incorporation into membranes influences the function of membrane proteins. We investigated the impact of the membrane incorporation of PUFAs, especially eicosapentaenoic acid (EPA) (C20:5 n-3), on the anti-atherogenic cholesterol efflux pathways. We used cholesteryl esters (CE)-loaded human monocyte-derived macrophages (HMDM) to mimic foam cells exposed to the FAs for a long period of time to ensure their incorporation into cellular membranes...

Adipose dysfunction links tightly to hepatic insulin resistance and gluconeogenesis. Ilexgenin A is reported with the ability to regulate lipid profile and protect the liver against high fat diet (HFD) -induced impairment. Here, we propose that ilexgenin A ameliorates hepatic insulin signaling and gluconeogenesis by regulating lipolysis in white adipose tissue (WAT). Pyruvate tolerance test and biochemical analysis coupled with the ex vivo siRNA knockdown and co-culture studies demonstrate that ilexgenin A suppresses inflammation-associated lipolysis in epididymal fat pad via 5'-AMP-activated protein kinase (AMPK) activation, thus inhibits diacylglycerol (DAG) accumulation and protein kinase C ε (PKCε) translocation in liver, leading to the improvement of insulin sensitivity and hepatic glucose production...

Nonalcoholic fatty liver disease is one of the most common complications of obesity. The Vitis vinifera L. grape skin extract (ACH09) is an important source of polyphenols, which are related to its antioxidant and antihyperglycemic activities. We hypothesized that ACH09 could also exert beneficial effects on metabolic disorders associated with obesity and evaluated ACH09's influence on high-fat (HF) diet-induced hepatic steatosis and insulin resistance in C57BL/6 mice. The animals were fed a standard diet (10% fat, control) or an HF diet (60% fat, HF) with or without ACH09 (200mg/[kg d]) for 12weeks...

BACKGROUND: Several studies associated high-fat intakes with a high incidence of age-related macular degeneration (AMD). Lutein and Zeaxanthin isomers (L/Zi) may counteract reactive oxygen species produced by oxidative stress. The present study was conducted to determine the possible effects of L/Zi administration on lipid profile, protein genes associated with oxidative stress and inflammation pathways in the obesity induced by a high-fat diet (HFD) in rodents. METHODS: Twenty-eight male Wistar rats were allocated into four groups as follows: (i) Control, (ii) Control + L/Zi, (iii) High Fat Diet (HFD), and (iv) HFD+ L/Z...

Obesity and type 2 diabetes are linked with chronic, low-grade inflammation in visceral adipose tissue (VAT). A unique population of VAT-resident CD4(+)Foxp3(+) Tregs plays a crucial role in regulating VAT inflammation and metabolic homeostasis. VAT-resident Tregs display a highly restricted TCR repertoire, suggesting they recognize certain autoantigen(s) in VAT. A dramatic reduction of VAT-resident Tregs has been shown to closely correlate with obesity-related VAT chronic inflammation and metabolic disorders...
