Lipid droplets (LD) play a central role in lipid homeostasis by controlling transient fatty acid (FA) storage and release from triacylglycerols stores, while preventing high levels of cellular toxic lipids. This crucial function in oxidative tissues is altered in obesity and type 2 diabetes. Perilipin 5 (PLIN5) is a LD protein whose mechanistic and causal link with lipotoxicity and insulin resistance has raised controversies. We investigated here the physiological role of PLIN5 in skeletal muscle upon various metabolic challenges...

The majority of patients with Type 2 diabetes require insulin therapy for treating hyperglycaemia. There are several regimens available for insulin initiation and maintenance. Insulin analogues have been developed to mimic normal physiology as closely as possible. Biphasic analogues can target both fasting and postprandial hyperglycaemia, with the added advantage of being premixed and thus convenient for the patient. A practical and feasible option is to initiate insulin with one or more biphasic preparations at mealtimes, thus providing both basal and prandial coverage...

Exploring the cell biology of hepatocytes in vitro could be a powerful strategy to dissect the molecular mechanisms underlying the structure and function of the liver in vivo. However, this approach relies on appropriate in vitro cell culture systems that can recapitulate the cell biological and metabolic features of the hepatocytes in the liver whilst being accessible to experimental manipulations. Here, we adapted protocols for high-resolution fluorescence microscopy and quantitative image analysis to compare two primary hepatocyte culture systems, monolayer and collagen sandwich, with respect to the distribution of two distinct populations of early endosomes (APPL1 and EEA1-positive), endocytic capacity, metabolic and signaling activities...

OBJECTIVE: There is a dearth of published literature comparing glucose variability (GV) between different insulin regimens in type 2 diabetes. This cohort study compares GV using continuous glucose monitoring (CGM) in patients with well-controlled type 2 diabetes using four common insulin regimens: basal insulin + oral drugs (BO), basal insulin + glucagon-like peptide 1 receptor agonist (GLP-1 RA) (BGLP), premixed insulin (PM), and basal-bolus insulin (BB). RESEARCH DESIGN AND METHODS: Consecutive patients from three endocrinology clinics who met study criteria-type 2 diabetes, age 18 to 80 years, BMI ≤ 45 kg/m(2), stable insulin regimen for a minimum of 6 months, and stable A1C value ≤7...

Recent findings in adipocytes suggest that mitogen-activated protein kinase (MAPK)/extracellular-regulated signaling kinase (ERK) kinase 1/2 (MEK1/2) signaling regulates regulated in development and DNA damage 1 (REDD1) protein expression. Similarly, our previous work show that a lack of REDD1 protein expression, and associated hyperactive basal mechanistic target of rapamycin (mTOR) signaling, limits skeletal muscle's response to insulin. Therefore, we sought to determine: 1) if MEK1/2 inhibition is sufficient to reduce REDD1 protein expression and subsequently insulin receptor substrate-1 (IRS-1) tyrosine phosphorylation via negative feedback of hyperactive mTOR in REDD1 wild-type (WT) mice and 2) if rapamycin-mediated mTOR inhibition is sufficient to improve IRS-1 tyrosine phosphorylation in REDD1 knockout (KO) mice...

Persistent amenorrhea is a frequent condition affecting anorexic patients after stable weight recovery. It has been proposed that it could be due to alterations of the hypothalamic-pituitary-gonadal axis linked with persistent hormonal impairments, such as relative hypercortisolemia and hypoleptinemia, and psychological symptoms related to anorexia nervosa (AN). The aim of our study was to evaluate the metabolic and hormonal pattern involved in the persistence of amenorrhea after recovery from AN. Eight weight-recovered anorexic patients with amenorrhea were investigated and matched with 10 healthy eumenorrhoic women, comparable for age and BMI...

Type 2 diabetes is characterized by triglyceride accumulation and reduced lipid oxidation capacity in skeletal muscle. SIRT1 is a key protein in the regulation of lipid oxidation and its expression is reduced in the skeletal muscle of insulin resistant mice. In this tissue, Sirt1 up-regulates the expression of genes involved in oxidative metabolism and improves mitochondrial function mainly through PPARGC1 deacetylation. Here we examined whether Sirt1 overexpression mediated by adeno-associated viral vectors of serotype 1 (AAV1) specifically in skeletal muscle can counteract the development of insulin resistance induced by a high fat diet in mice...

OBJECTIVE: Background: ADAMTS-1 is a matrix metalloproteinase which cleaves versican in the cumulus oocyte complex, under the effect of luteinizing hormone surge in the periovulatory period. Altered levels of it may have a role in the disease pathogenesis. OBJECTIVE: We aimed to detect serum versican and a disintegrin and metalloproteinase with thrombospondin motif- 1 (ADAMTS-1) levels in polycystic ovary syndrome (PCOS) patients, and compare the results with the healthy controls...

The medio-basal hypothalamus (MBH) contains neurons capable of directly detecting metabolic signals such as glucose to control energy homeostasis. Among them, glucose-excited (GE) neurons increase their electrical activity when glucose rises. In view of previous work, we hypothesized that Transient Receptor Potential Canonical type-3 (TRPC3) channels are involved in hypothalamic glucose detection and the control of energy homeostasis.To investigate the role of TRPC3, we used constitutive and conditional TRPC3-deficient mice models...

A mathematical model of the dynamics of insulin and glucose during a frequently sampled intravenous glucose tolerance test (IVGTT) in sheep was developed that characterizes the large second-phase insulin secretion response in sheep during IVGTT. The model was fit to measurements of the glucose and insulin dynamics during standard IVGTT ( = 42) and modified IVGTT ( = 40), where insulin was injected 60 min after the initiation of the IVGTT. The correlation between log insulin sensitivity determined by hyperglycemic clamps (HGC) and standard IVGTT was = 0...

Pulse-chase radiolabeling of cells with radioactive amino acids is a common method for tracking the biosynthesis of proteins. Radiolabeled newly synthesized proteins can be analyzed by a number of techniques such as two dimensional gel electrophoresis (2DE). This chapter presents a protocol for the biosynthetic labeling of pancreatic islets with (35)S-methionine in the presence of basal and stimulatory concentrations of glucose, followed by subcellular fractionation to produce a secretory granule fraction and analysis of the granule protein contents by 2DE...

INTRODUCTION: Lack of control in diabetic patients has stimulated the development of new insulin analogues. One of these was basal insulin peglispro (BIL) or LY2605541; it had a large hydrodynamic size, flat pharmacokinetic profile, half life of 2-3 days and acted preferably in the liver. METHODS: We reviewed the recent literature examining the pharmacokinetics, pharmacodynamics, efficacy and safety of BIL treatment in type 2 diabetes patients. RESULTS: The pharmacodynamic and pharmacokinetic outline of BIL seemed to have an advantage over neutral protamine Hagedorn and glargine insulins...

AIMS: Leptin plays an important role in the pathogenesis of obesity and diabetes, yet the regulatory mechanisms of this hormone have not been fully elucidated. In this study, we aimed to clarify the roles of insulin and glucose in leptin secretion and mRNA production using inhibitors of insulin signal transduction in adipocytes cultured under glucose-free or normal conditions. METHODS: Differentiated 3T3-L1 adipocytes were stimulated with insulin in combination with inhibitors for phosphoinositide 3-kinase (PI3K), Akt, and phosphodiesterase 3B (PDE3B), as well as epinephrine and a cyclic AMP (cAMP) analog under glucose-free or normal conditions...

OBJECTIVE: To study longitudinal growth in children with type 1 diabetes mellitus. METHODS: Anthropometry, disease duration, insulin regimens and HbA1C recorded from patients with diabetes enrolled in a specialty clinic. RESULTS: 160 children (75 boys; mean (SD) age 9.4 (3.3) y) were enrolled. 35% children had low (<25th centile) height velocity. Disease duration and HbA1C affected height velocity (adjusted for puberty). Children on basal-bolus had higher height velocity Z scores than those on a split mix regimen [(0...

AIMS: Basal insulin peglispro (BIL) is a novel PEGylated basal insulin with a flat pharmacokinetic and glucodynamic profile and reduced peripheral effects, which results in a hepato-preferential action. In Phase 3 trials, patients with T1DM treated with BIL had lower prandial insulin requirements, yet improved prandial glucose control, relative to insulin glargine (GL). We hypothesized that this may be due to an enhanced sensitivity to prandial insulin with BIL resulting from lower chronic peripheral insulin action...

Complications in pregnancy elevate fetal norepinephrine (NE) concentrations. Previous studies in NE-infused sheep fetuses revealed that sustained exposure to high NE resulted in lower expression of α2-adrenergic receptors in islets and increased insulin secretion responsiveness after acutely terminating the NE infusion. In this study, we determined if the compensatory increase in insulin secretion following chronic elevation of NE is independent of hyperglycemia in sheep fetuses and whether it is persistent in conjunction with islet desensitization to NE...

Myoinositol and D-chiro inositol, which are inositol isomers, have been shown to possess insulin-mimetic properties and to improve insulin resistance, especially in women with polycystic ovary syndrome. However, it has not been determined if this relationship exists also in children. Based on these previous findings, we hypothesized that inositol could be effective in improving insulin sensitivity in children with insulin resistance. To evaluate this hypothesis, we administered both inositol formulations before carrying out an oral glucose tolerance test (OGTT) in a group of obese insulin-resistant male children with high basal insulin levels and compared the values obtained with an OGTT previously conducted without inositol, in the same group, with unchanged BMI...
