Low AS160 and high SGK basal phosphorylation associates with impaired incretin profile and type 2 diabetes in adipose tissue of obese patients

Obesity and related metabolic disorders, including type 2 diabetes mellitus (T2DM), alarmingly grow up in the modern society thus representing a serious issue for endocrinology and medicine. Obesity is the major risk factor for T2DM [1], however, not all obese individuals ultimately develop T2DM. Nevertheless, mechanisms linking obesity to T2DM are being extensively studied.

Abstract Obesity has become a global health problem. Lifestyle modification and medical treatment only appear to yield short-term weight loss. Roux-en-Y gastric bypass (RYGB) is the most popular bariatric procedure, and it sustains weight reduction and results in the remission of obesity-associated comorbidities for obese individuals. However, patients who undergo this surgery may develop hypoglycemia. To date, the diagnosis is challenging and the prevalence of post-RYGB hypoglycemia (PRH) is unclear. RYGB alters the anatomy of the upper gastrointestinal tract and has a combined effect of caloric intake restrictio...

Purpose of review Among the gastrointestinal hormones, the incretins: glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 have attracted interest because of their importance for the development and therapy of type 2 diabetes and obesity. New agonists and formulations of particularly the GLP-1 receptor have been developed recently showing great therapeutic efficacy for both diseases. Recent findings The status of the currently available GLP-1 receptor agonists (GLP-1RAs) is described, and their strengths and weaknesses analyzed. Their ability to also reduce cardiovascular and renal risk is describe...

Abstract T1R3 protein, the main subunit of the sweet taste receptor and receptor of amino acid taste, is expressed in the epithelium of the tongue and gastrointestinal tract, in β cells of the pancreas, hypothalamus, and numerous other organs. Recently, convincing evidences on the involvement of T1R3 in the control of carbohydrate and lipid metabolism, and the control of incretin and insulin production were obtained. In the study on Tas1r3-gene knockout mouse strain and parent C57BL/6J strain as a control, the data on the effect of T1R3 on morphological characteristics of Langerhans islets in the pancreas wer...

From the Incretin Concept and the Discovery of GLP-1 to Today's Diabetes Therapy Jens Juul Holst* Department of Biomedical Sciences, Novo Nordisk Foundation Center for Basic Metabolic Research, University of Copenhagen, Copenhagen, Denmark Researchers have been looking for insulin-stimulating factors for more than 100 years, and in the 1960ties it was definitively proven that the gastrointestinal tract releases important insulinotropic factors upon oral glucose intake, so-called incretin hormones. The first significant factor identified was the duodenal glucose-dependent insulinotropic polypeptide, GIP, wh...

Conclusions: Bariatric surgery appears to be capable of partially reversing the obesity-related epigenome. The identification of potential epigenetic biomarkers predictive for the success of bariatric surgery may open new doors to personalized therapy for severe obesity. Introduction Obesity is currently a huge healthcare problem, worldwide, and is a risk factor for several diseases such as type 2 diabetes (T2D), cardiovascular disease and cancer (1). As the prevalence of obesity reaches pandemic proportions, this metabolic disease is estimated to become the biggest cause of mortality in the near future (2). In fact,...

Bariatric surgery is currently the best treatment for type 2 diabetes mellitus (DM2) in patients with obesity. Although different surgical techniques produce different results, better glycemic control is achieved with surgical procedures compared to clinical treatments [1 –3].

Background: Type 2 diabetes mellitus is a disease correlated with obesity. Obese patients has suppressed incretin effect and inbalance of glycemic homeostasis. Studies have shown improvement in DM2 after Roux-en-Y gastric bypass (RYGB). The mechanisms of glycemic control may be long-term and short-term. The mechanisms of early action are linked to caloric restriction, improvement of insulin resistance, pancreatic beta cell function and return of the incretin effect through the increase of GLP1 and GIP, but data are conflicting.

ConclusionsBased on these results, the pharmacology of LY3298176 translates from preclinical to clinical studies. LY3298176 has the potential to deliver clinically meaningful improvement in glycaemic control and body weight. The data warrant further clinical evaluation of LY3298176 for the treatment of T2DM and potentially obesity.

To the Editor Inge et al have shown that bariatric surgery has a greater association than medical treatment alone in achieving an improvement of type 2 diabetes mellitus and its comorbidities in obese adolescents. The mechanism seems to go beyond the magnitude of weight loss alone and include an improvement in incretin profiles, insulin secretion, and insulin sensitivity.
