Obesity due to excessive lipid accumulation is closely associated with metabolic diseases such as type 2 diabetes, insulin resistance and inflammation. Therefore, a detailed understanding of the molecular mechanisms that underlie adipogenesis is crucial to develop treatments for diseases related to obesity. Here, we found that the microRNA-204-5p (miR-204-5p) was expressed at low levels in fat tissues from obese mice fed long-term with a high-fat diet (HFD). Overexpression or inhibition of miR-204-5p in vitro in 3T3-L1 preadipocytes significantly inhibited or promoted 3T3-L1 proliferation, respectively, an effect mediated by regulating cell proliferation factors...

The greatest burden of cardiovascular disease is now carried by developing countries with cardiometabolic conditions such as metabolic syndrome, obesity and inflammation believed to be the driving force behind this epidemic. Dietary fiber is known to have protective effects against obesity, type 2 diabetes, cardiovascular disease and the metabolic syndrome. Considering the emerging prevalence of these cardiometabolic disease states across the epidemiologic transition, the objective of this study is to explore these associations of dietary fiber with cardiometabolic risk factors in four countries across the epidemiologic transition...

BACKGROUND/OBJECTIVES: The occurrence of chronic inflammation in visceral adipose tissue (VAT) in obese subjects precipitates the development of insulin resistance and type 2 diabetes (T2D). Anthocyanins and their main metabolite protocatechuic acid (PCA) have been demonstrated to stimulate insulin signaling in human adipocytes. The aim of this study was to investigate whether PCA is able to modulate insulin responsiveness and inflammation in VAT from obese (OB) and normal weight (NW) subjects...

Diabetes is associated with increased cardiovascular disease (CVD) risk. Previous studies with statins have established that a 1 mmol/l reduction in LDL-cholesterol reduces CVD events by 21% over 5 years in people with diabetes. More recently, trials in people with acute coronary syndromes showed that ezetimibe reduced CVD events by 6% at 5 years and achieved a LDL-cholesterol of 1.6 mmol/l with better results in people with Type 2 diabetes. Several novel lipid-lowering therapies have recently been developed...

Accumulation and polarization of anti-inflammatory M2 to proinflammatory M1 macrophage in the adipose tissue of obese diabetic mice is an important pathogenic signature. It worsens lipid induced inflammation and insulin resistance. Here we demonstrate that a small molecule, a peroxyvanadate compound i.e. DmpzH [VO(O2 )2 (dmpz)] or dmp, could robustly decrease macrophage infiltration, accumulation and their polarization in high fat diet (HFD) induced obese diabetic mice. In searching the underlying mechanism it was revealed that SIRT1 level was strikingly low in the inflamed adipose tissue of HFD mice as compared to mice fed with standard diet (SD)...

A primary cause of disease progression in type 2 diabetes (T2D) is β cell dysfunction due to inflammatory stress and insulin resistance. However, preventing β cell exhaustion under diabetic conditions is a major therapeutic challenge. Here, we identify the vitamin D receptor (VDR) as a key modulator of inflammation and β cell survival. Alternative recognition of an acetylated lysine in VDR by bromodomain proteins BRD7 and BRD9 directs association to PBAF and BAF chromatin remodeling complexes, respectively...

AIMS/HYPOTHESIS: Despite improved understanding of the pathophysiology of type 2 diabetes mellitus, explanations for individual variability in disease progression and response to treatment are incomplete. The gut microbiota has been linked to the pathophysiology of type 2 diabetes mellitus and may account for this variability. We conducted a systematic review to assess the effectiveness of dietary and physical activity/exercise interventions in modulating the gut microbiota and improving glucose control in adults with type 2 diabetes mellitus...

Macrophages and inflammasome pathway are involved in high-glucose toxicity and development of insulin resistance. Silymarin (SMR) was known to modulate glucose homeostasis and reduce inflammation. However, it is still unknown whether SMR possess anti-hyperglycemic effects in diabetic-like knockout mice (Hnf-1αkin/- /Ins.cre mice) with insulin resistance and also unclear how SMR regulates LPS induced stress markers and pro-inflammatory cytokines under stresses of high glucose (HG) or NLRP3 inflammasome activation...

Spontaneously Diabetic Torii (SDT) fatty rats, a new obese diabetic model, reportedly presented with features of non-alcoholic steatohepatitis (NASH) after 32 weeks of age. We tried to accelerate the onset of NASH in SDT fatty rats using dietary cholesterol loading and noticed changes in the blood choline level which is expected to be a NASH biomarker. Body weight and biochemical parameters were measured from 8 to 24 weeks of age. At 16 or 24 weeks, pathophysiological analysis of the livers were performed, hepatic lipids, lipid peroxides, and the expression of mRNA related to triglyceride (TG) synthesis, inflammation, and fibrosis were evaluated...

High glucose combined with high FFAs can contribute to the unfavorable development of type 2 diabetes mellitus (T2DM) and monocytes/macrophages are important in the occurrence and development of T2DM, which is regarded as a type of low‑grade inflammation. Although our previous study demonstrated that increased expression of P2X7 receptor (P2X7R) in peripheral blood monocytes may alter the innate immune system and that long non‑coding (lnc)RNA uc.48+ was involved in diabetic neuropathic pain, the involvement of uc...

Since the successful molecular cloning in 1998 of GM3 synthase (GM3S, ST3GAL5), the enzyme responsible for initiating biosynthesis of all complex gangliosides, the efforts of our research group have been focused on clarifying the physiological and pathological implications of gangliosides, particularly GM3. We have identified isoforms of GM3S proteins having distinctive lengths of N-terminal cytoplasmic tails, and found that these cytoplasmic tails define subcellular localization, stability, and in vivo activity of GM3S isoforms...

There is a widely acknowledged association between insulin resistance and obesity/type 2 diabetes (T2DM), and insulin sensitizing treatments have proved effective in preventing diabetes and inducing weight loss. Obesity and T2DM are also associated with increased inflammation. Mangosteen is a tropical tree, whose fruits—known for their antioxidant properties—have been recently suggested having a possible further role in the treatment of obesity and T2DM. The objective of this pilot study has been to evaluate safety and efficacy of treatment with mangosteen extract on insulin resistance, weight management, and inflammatory status in obese female patients with insulin resistance...

Caspases, a family of cysteine-dependent aspartate-specific proteases, are central to the maintenance of cellular and organismal homoeostasis by functioning as key mediators of the inflammatory response and/or apoptosis. Both metabolic inflammation and apoptosis play a central role in the pathogenesis of metabolic disease such as obesity and the progression of nonalcoholic steatohepatisis (NASH) to more severe liver disease. Obesity and nonalcoholic fatty liver disease (NAFLD) are the leading global health challenges associated with the development of numerous comorbidities including insulin resistance, type-2 diabetes and early mortality...
