In MIN6 pancreatic β-cells, glucose and insulin act in a synergistic manner to regulate the dynamics of Phosphatidylinositol (3,4,5)-trisphosphate (PIP3). However, the precise regulatory mechanism behind such an experimentally observed synergy is poorly understood. In this article, we propose a phenomenological mathematical model for studying the glucose and insulin driven PIP3 activation dynamics under various stimulatory conditions to unfold the mechanism responsible for the observed synergy. The modeling study reveals that the experimentally observed oscillation in PIP3 dynamics with disparate time scales for different external glucose doses is mainly orchestrated by the complex dynamic regulation of cytosolic Ca(2+) in β-cells...

OBJECTIVE: Although white adipose tissue mass and distribution correlates with cardiovascular disease, the fat cell-specific perturbations underlying this association are not known. We determined the relationship between adipocyte size and lipid metabolism with cardiovascular risk. DESIGN/SUBJECTS: Adipocyte size as well as spontaneous (basal) and hormone-stimulated effects on adipocyte lipid metabolism (lipolysis and lipogenesis) were investigated in abdominal subcutaneous adipose tissue of 304 men and 775 women...

Destruction of the insulin-producing β-cells is the key determinant of diabetes mellitus regardless of their types. Due to their anatomical location within the islets of Langerhans scattered throughout the pancreas, it is difficult to monitor β-cell function and mass clinically. To this end, we propose to use a mathematical model of glucose-insulin homeostasis to estimate insulin secretion, glucose uptake by tissues, and hepatic handling of glucose. We applied the mathematical model by Lombarte et al. (2013) to compare various rate constants representing glucose-insulin homeostasis between lean (11% fat)- and high fat diet (HFD; 45% fat)-fed mice...

Our previous studies have demonstrated that prenatal caffeine exposure (PCE) induced an intrauterine programming of hypothalamic-pituitary-adrenal axis (HPAA)-associated neuroendocrine metabolism in 3-month-old offspring rats. In this study, we aimed to confirm this programming disorder and high susceptibility to metabolic syndrome (MS) in 10-month-old female PCE offspring with postnatal catch-up growth. We found that PCE female offspring rats showed decreased bodyweight but a higher rate of weight gain after birth...

BACKGROUND AND OBJECTIVES: Ultra-long-acting insulin degludec (DEG) has a longer duration of action and less daily variability relative to other basal insulin (BI), and thus may benefit patients with type 1 diabetes mellitus (T1DM). We examined the impact of switching BI to DEG on glycemic control and insulin dose in T1DM. METHODS: T1DM patients (n = 22; six male; mean age: 64.5 ± 12.6 years) receiving basal-bolus insulin therapy were included. Initially, the BI dose was replaced with DEG in a 1:1 ratio; 80-100% of the total dose was replaced with DEG for multiple basal insulin injections...

This study was designed to investigate a possible role of the N-terminal tripeptide of insulin-like growth factor-1 (IGF-I), Gly-Pro-Glu (GPE), physiologically generated in neurons following IGF-I-specific cleavage, in promoting neural regeneration after an injury. Primary cultures of mouse neural stem cells (NSCs), obtained from 13.5 Days post-conception (dpc) mouse embryos, were challenged with either GPE, growth hormone (GH), or GPE + GH and the effects on cell proliferation, migration, and survival were evaluated both under basal conditions and in response to a wound healing assay...

BACKGROUND: Obese insulin-resistance is one of the most important risk factor for cardiovascular diseases including ischemic heart disease (IHD). Growing evidences suggest that the susceptibility to myocardial ischemia-reperfusion (I/R) injury is increased in an obese insulin-resistance condition. Based on the currently available evidence from human and animal studies, this review mainly focuses on the influence of obese insulin-resistance on the outcome of the I/R insult to the heart...

BACKGROUND: Recent studies suggest that glycemic variability could influence the risk of complications in type 1 diabetes mellitus (T1DM). There are no data about the action of vitamin D (VD) on glycemic variability. Our pilot study aims to evaluate glycemic variability and insulin needs in patients with T1DM supplemented with VD. METHODS: 22 patients received doses of 4000 and 10000 IU/day of cholecalciferol for 12 weeks, according to the patient's baseline VD levels and underwent continuous glucose monitoring system...

BACKGROUND: Exercise causes glycemic disturbances in individuals with type 1 diabetes (T1D). Continuous moderate-intensity aerobic exercise (CON) generally lowers blood glucose (BG) levels and often leads to hypoglycemia. In comparison, circuit-based exercise (CIRC) may attenuate the drop in BG. The goal of this study is to contrast the effects of basal insulin suspension at the onset of two different forms of exercise (CON vs. CIRC). METHODS: Twelve individuals (six men and six women) with T1D on insulin pump therapy were recruited for the study...

Background Degludec is an ultralong-acting, once-daily basal insulin that is approved for use in adults, adolescents, and children with diabetes. Previous open-label studies have shown lower day-to-day variability in the glucose-lowering effect and lower rates of hypoglycemia among patients who received degludec than among those who received basal insulin glargine. However, data are lacking on the cardiovascular safety of degludec. Methods We randomly assigned 7637 patients with type 2 diabetes to receive either insulin degludec (3818 patients) or insulin glargine U100 (3819 patients) once daily between dinner and bedtime in a double-blind, treat-to-target, event-driven cardiovascular outcomes trial...

BACKGROUND: Not only within-day glycemic variability but also day-to-day glycemic variability is a risk factor for diabetic patients. However, the ways of controlling day-to-day glycemic variability are unclear. We hypothesized that the durability of basal insulin plays an important role in controlling day-to-day glycemic variability in type 2 diabetes patients, and we therefore aimed to evaluate whether glargine U300, which exhibits prolonged absorption compared with glargine U100 but the same composition as glargine U100, would lead to improved day-to-day glycemic variability...

BACKGROUND: To maintain fasting blood glucose levels within near to the normal range in type 1 diabetes mellitus (DM), frequent insulin dose adjustments may be required with short-, intermediate- and long-acting insulin formulations. Patients on human insulin generally experience weight gain over time, regardless of the level of glycaemic control achieved. OBJECTIVES: To determine the effects of human insulin, adjusted quarterly to achieve glycaemic control, on body mass index (BMI), and establish dose regimens that achieve optimal glycaemic control without increasing BMI in patients with type 1 DM at the Kalafong Diabetes Clinic in Pretoria, South Africa...

BACKGROUND AND OBJECTIVE: People with T2DM who initiate basal insulin therapy often stop therapy temporarily or permanently soon after initiation. This study analyzes the reasons for and correlates of stopping and restarting basal insulin therapy among people with T2DM. METHODS: An online survey was completed by 942 insulin-naïve adults with self-reported T2DM from Brazil, France, Germany, Japan, Spain, UK, and US. Respondents had initiated basal insulin therapy within the 3-24 months before survey participation and met criteria for one of three persistence groups: continuers had no gaps of ≥7 days in basal insulin treatment; interrupters had at least one gap in insulin therapy of ≥7 days within the first 6 months after initiation and had since restarted basal insulin; and discontinuers stopped using basal insulin within the first 6 months after initiation and had not restarted...

BACKGROUND AND OBJECTIVE: People with type 2 diabetes mellitus (T2DM) often interrupt basal insulin treatment soon after initiation. This study aimed to describe the experiences during and after basal insulin initiation among people with T2DM with different persistence patterns. METHODS: Adults with T2DM from France, Germany, Spain, UK, US, Brazil, and Japan were identified from consumer panels for an online survey. Respondents who initiated basal insulin 3-24 months prior to survey date,were categorized as continuers (no gaps of ≥7 days in insulin treatment); interrupters (first gap ≥7 days within 6 months of initiation and restarted insulin); and discontinuers (stopped insulin for ≥7 days within 6 months of initiation without restarting)...

Human β-cells are functionally mature by the age of one year. The timing and mechanisms of this maturation are unknown owing to the exceptional availability of testable tissue. Here, we report the first in vitro study of insulin secretion by islets from a 5 day-old newborn. Glucose alone was inefficient but glucose-stimulation became concentration-dependent, displayed a biphasic time-course and was of similar magnitude as in infant islets when β-cell cAMP was raised by forskolin. Tolbutamide alone was effective in low glucose, but its effect was not augmented by high glucose...
