Type 2 diabetes (T2DM) is a polygenic metabolic disorder characterized by hyperglycemia occurring as a result of impaired insulin secretion or insulin resistance. Various environmental and genetic factors interact and increase the risk of T2DM and its complications. Among the various genetic factors associated with T2DM, single nucleotide polymorphism in different candidate genes have been studied intensively and the resulting genetic variants have been found to have either positive or negative association with T2DM thereby increasing or decreasing the risk of T2DM, respectively...

Type 2 diabetes mellitus (T2DM) is related to increased risk of papillary thyroid carcinoma (PTC). Insulin-like growth factor-1 receptor (IGF-1R) is increased in patients with T2DM. The increased IGF-1R may be responsible for the development of PTC. In this study, we investigated the expression of phosphorylation of Akt (p-Akt)/survivin pathway activated by IGF-1R in PTC subjects with and without diabetes.Clinicopathological data of 20 PTC patients with T2DM were retrospectively analyzed and compared with those of 21 PTC subjects without diabetes...

The free fatty acid receptor 1 (FFAR1/GPR40) amplifies glucose-dependent insulin secretion; therefore, it has attracted widespread attention as a promising antidiabetic target. Current clinical proof of concept also indicates that FFAR1 agonists achieve the initially therapeutic endpoint for the treatment of type 2 diabetes mellitus (T2DM) without the hypoglycemic risk. Thus, many pharmaceutical companies and academic institutes are competing to develop FFAR1 agonists. However, several candidates have been discontinued in clinical trials, often without reporting the underlying reasons...

Although the importance of macrophages in nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) has been recognized, it remains elusive how macrophages impact hepatocytes. Mineralocorticoid receptor (MR) has been implied to play important roles in NAFLD and T2DM. However, cellular and molecular mechanisms are largely unknown. Here we report that myeloid MR knockout (MRKO) improves glucose intolerance, insulin resistance, and hepatic steatosis in obese mice. Estrogen signaling is sufficient and necessary for such improvements...

OBJECTIVE: The combination of basal insulin plus a glucagon-like peptide 1 receptor agonist (GLP-1RA) has been proposed as a treatment option to intensify insulin therapy in type 2 diabetes. We performed a meta-analysis of randomized controlled trials (RCTs) comparing this combination strategy to other injectable antidiabetes treatments on metabolic control in adult patients with type 2 diabetes. RESEARCH DESIGN AND METHODS: We conducted an electronic search until November 2016 on many electronic databases to identify RCTs assessing changes in HbA1c, proportion of patients at HbA1c target ≤7% (53 mmol/mol), hypoglycemia, and weight change...

OBJECTIVE: Pharmacologically induced glycosuria elicits adaptive responses in glucose homeostasis and hormone release, including decrements in plasma glucose and insulin levels, increments in glucagon release, enhanced lipolysis, and stimulation of ketogenesis, resulting in an increase in ketonemia. We aimed at assessing the renal response to these changes. RESEARCH DESIGN AND METHODS: We measured fasting and postmeal urinary excretion of glucose, β-hydroxybutyrate (β-HB), lactate, and sodium in 66 previously reported patients with type 2 diabetes and preserved renal function (estimated glomerular filtration rate ≥60 mL · min(-1) · 1...

This study aimed to investigate the physicochemical properties and antidiabetic effects of a polysaccharide obtained from corn silk (PCS2). PCS2 was isolated and the physicochemical properties were characterized. The hypoglycemic effects were determined using the high-fat diet and streptozocin induced type 2 diabetic mellitus (T2DM) insulin resistance mice. The results showed that PCS2 was a heteropolysaccharide with the average molecular weight of 45.5kDa. PCS2 was composed of d-galactose, d-mannose, d-(+)-glucose, d-(+)-xylose, l-arabinose and l-rhamnose...

BACKGROUND: It is known that successful pancreas transplantation enables patients with diabetes to maintain a normal glucose level without insulin and reduces diabetes-related complications. However, we have little information about the foot-specific morbidity in patients who have undergone successful pancreas transplantation. The purpose of this study was to investigate the prevalence and predisposing factors for foot complications after successful pancreas transplantation. METHODS: This retrospective study included 218 patients (91 males, 127 females) who had undergone pancreas transplantation for diabetes...

Glucose is the main energy source of the body's cells and is essential for normal metabolism. Two pancreatic hormones, insulin and glucagon, are involved in glucose home-ostasis. Alteration in the plasma glucose and insulin concentrations could lead to distinct symptoms and diseases, ranging from mental function impairment to coma and even death. Type 2 diabetes, insulin resistance and metabolic syndrome are typical examples of abnormal glucose metabolism that increase the risk for cardiovascular disease and mortality...

Age is one of the main risk factor for the presence of obstructive sleep apnea (OSA). This syndrome is associated with hypertension, cardiovascular disease, cognitive impairment and metabolic abnormalities, such as type 2 diabetes. Continuous positive airway pressure (CPAP) represents the gold standard therapy, but its benefit is still to be determined in very elderly. We report the blood pressure and metabolic changes in a very elderly obese with severe OSA after 3-month CPAP therapy. We have evaluated a very elderly obese male affected by severe symptomatic OSA, poor controlled nocturnal hypertension and insulin resistance...

Oxidative stress induces endogenous antioxidants via nuclear factor erythroid 2-related factor 2 (Nrf2), potentially preventing tissue injury. We investigated whether insulin affects renal Nrf2 expression in type 1 diabetes (T1D) and studied its underlying mechanism. Insulin normalized hyperglycemia, hypertension, oxidative stress and renal injury, inhibited renal Nrf2 and angiotensinogen (Agt) gene expression and up-regulated heterogeneous nuclear ribonucleoprotein F (hnRNP F) and hnRNP K expression in Akita mice with T1D...

Context: The contribution of insulin resistance vs. adiposity to bone mineral density (BMD), bone turnover and fractures in humans remains unclear. Objective: Evaluate BMD and bone turnover markers (BTM) in lean (n=18) and overweight/obese individuals with (n=17) and without type 2 diabetes (n=34, deemed insulin-sensitive [Obsensitive, n=15] or insulin-resistant [Obresistant, n=19] by HOMA-IR). Design: Observational study. Outcome measures: Insulin sensitivity assessed by hyperinsulinemic-euglycemic clamp; whole body BMD and fat mass (FM) by DXA; and BTM (osteocalcin [OC], procollagen type-1 propeptide [P1NP] and collagen type-1 cross-linked C-telopeptide [CTx]) fasting and during clamp hyperinsulinemia...

Whole-body vibration has gained attention as a potential exercise mimetic, but direct comparisons with the metabolic effects of exercise are scarce. To determine whether whole-body vibration recapitulates the metabolic and osteogenic effects of physical activity, we exposed male wildtype (Wt) and leptin receptor deficient (db/db) mice to daily treadmill exercise or whole-body vibration for three months. Body weights were analyzed and compared with Wt and db/db mice that remained sedentary. Glucose and insulin tolerance testing revealed comparable attenuation of hyperglycemia and insulin resistance in db/db mice following treadmill exercise or whole-body vibration...

Context: Non-alcoholic fatty liver disease and elevated circulating branched-chain amino acids (BCAAs) are common characteristics of obesity and type 2 diabetes. In rodents, brain insulin signaling controls both hepatic triglyceride secretion and BCAA catabolism. Whether brain insulin signaling controls similar metabolic pathways in humans is unknown. Objective: Here we assessed if intranasal insulin, a method to preferentially deliver insulin to the central nervous system, is able to modulate hepatic lipid content and plasma BCAAs in humans...

The onset and/or progression of type 2 diabetes (T2D) can be prevented if intervention is early enough. As such, much effort has been placed on the search for indicators predictive of pre-diabetes and disease onset or progression. An increasing body of evidence suggests that changes in plasma glycine may be one such biomarker. Circulating glycine levels are consistently low in patients with T2D. Levels of this non-essential amino acid correlate negatively with obesity and insulin resistance. Plasma glycine correlates positively with glucose disposal, and rises with interventions such as exercise and bariatric surgery that improve glucose homeostasis...
