Acetytransferase P300 impairs insulin signaling in obesity

Project description:Insulin resistance is the hallmark of obese and type 2 diabetes patients. Defective insulin sensitivity in the liver results in increased glucsoe production, which is the major cause of hyperglycemia in diabetic patients. Increased lipopolysaccharide (LPS) leakage from the gut of diet-induced obesity causes insulin resisitance; moreover, activation of deacetylase Sirtuin1 restore insulin sensitivity in obesity. However, the mechanism resulting in insulin resistance by LPS remains poorly understood. Here, we show that Ep300 (P300) harboring an intrinsic acetyltransferase activity was rapidly induced in the liver of animals fed a high-fat diet, and the induction of Ep300 is through LPS-stimulated activation of ER stress. Induced Ep300 impairs insulin signaling by acetylating mediators in insulin signaling. Inhibition of P300 acetyltransferase activity improves insulin signaling. Thus, Ep300 acetyltransferase activity is a therapeutic target.

The inflammasome is a central player in the induction of obesity and insulin resistance

Project description:Inflammation plays a key role in the pathogenesis of obesity. Chronic overfeeding leads to macrophage infiltration in the adipose tissue, resulting in pro-inflammatory cytokine production. Both microbial and endogenous danger signals trigger assembly of the intracellular innate immune sensor Nlrp3 [NLR family, pyrin domain containing 3] resulting in caspase-1 activation and production of pro-inflammatory cytokines interleukin (IL)-1beta and IL-18. Here, we showed that mice deficient in Nlrp3, ASC [apoptosis-associated speck-like protein containing a CARD; a.k.a PYCARD (PYD and CARD domain containing)] and caspase-1 were resistant to the development of high fat diet-induced obesity, which correlated with protection from obesity-induced insulin resistance. Detailed metabolic and molecular phenotyping demonstrated that the inflammasome controls energy expenditure and adipogenic gene expression during chronic overfeeding. These findings reveal a critical function of the inflammasome in obesity and insulin resistance and suggest inhibition of the inflammasome as a potential therapeutic strategy. Keywords: Expression profiling by array Wild-type (WT), ASC-null and Casp1-null mice were subjected to high fat diet feeding for 16 weeks. After the diet intervention period, the animals were killed and epididymal white adipose tissue was removed. Total RNA was isolated and subjected to gene expression profiling.

IL-37 protects against obesity-induced inflammation and insulin resistance

Project description:Cytokines of the IL-1 family are important modulators of obesity-induced inflammation and the development of systemic insulin resistance. Here, we report that IL-37, a newly-described antiinflammatory member of the IL-1 family, affects obesity-induced inflammation and insulin resistance. IL-37 transgenic mice (IL-37tg) did not develop an obese phenotype in response to a high-fat diet (HFD). Unlike WT mice, IL-37tg mice exhibited reduced numbers of adipose tissue macrophages and preserved glucose tolerance and insulin sensitivity after 16 weeks of HFD. A short-term HFD intervention revealed that the IL-37-mediated improvement in glucose tolerance is independent of bodyweight. IL-37tg mice manifested a beneficial metabolic profile with higher circulating levels of the anti-inflammatory adipokine adiponectin. In vitro treatment of differentiating adipocytes with recombinant IL-37 reduced adipogenesis. The beneficial effects of recombinant IL-37 involved activation of AMPK signaling. In humans, steady-state IL-37 adipose tissue mRNA levels were positively correlated with insulin sensitivity, lower adipose tissue levels of leptin and a lower inflammatory status of the adipose tissue. These findings reveal IL-37 as an important anti-inflammatory modulator during obesity-induced inflammation and insulin resistance in both mice and humans and suggest that IL-37 is a potential target for the treatment of obesity-induced insulin resistance and type 2 diabetes. Gene arrays were performed on epidydimal white adipose tissue samples from wild type and human IL37-overexpressing transgenic mice fed a high fat diet for 16 weeks.
