In citrus processing industries, where up to 60% of the whole fruit is discarded, generates citrus waste (peel, seeds, membrane, and pulp) on a massive scale. The waste does not currently have high-value applications, instead the majority is disposed of or pelletized for animal feed. Therefore, a concise and efficacious protocol for processing of Kinnow mandarin (Citrus reticulata) fruit waste to numerous novel Brønsted acidic ionic liquids (3a-k) have been developed. BAILs were characterized using spectroscopic techniques (FT-IR and NMR)...

Adenoviral gene transfer of key β cell developmental regulators including Pdx1, Neurod1 and Mafa (PDA) has been reported to generate insulin-producing cells in liver. However, PDA insulin secretion is transient and glucose unresponsive. Here, we report that an additional β cell developmental regulator, insulin gene enhancer binding protein splicing variant (Isl1β), improved insulin production and glucose-responsive secretion in PDA mouse. Microarray gene expression analysis suggested that adenoviral PDA transfer required an additional element for mature β cell generation, such as Isl1 and Elf3 in liver...

Glucose is metabolized through anaerobic glycolysis and aerobic oxidative phosphorylation (OXPHOS). Perturbing glucose uptake and its subsequent metabolism can alter both glycolytic and OXPHOS pathways and consequently lactate and/or oxygen consumption. Production and secretion of lactate, as a consequence of glycolysis, leads to acidification of the extracellular medium. Molecular oxygen is the final electron acceptor in the electron transport chain, facilitating oxidative phosphorylation of ADP to ATP. The alterations in extracellular acidification and/or oxygen consumption can thus be used as indirect readouts of glucose metabolism and assessing the impact of inhibiting glucose transport through specific glucose transporters (GLUTs)...

Large amounts of pure and homogenous protein are a prerequisite for several biochemical and biophysical analyses, and in particular if aiming at resolving the three-dimensional protein structure. Here we describe the production of the rat glucose transporter 1 (GLUT1), a membrane protein facilitating the transport of glucose in cells. The protein is recombinantly expressed in the yeast Pichia pastoris. It is easily maintained and large-scale protein production in shaker flasks, as commonly performed in academic research laboratories, results in relatively high yields of membrane protein...

Cryptococcal meningitis (CM) is mostly seen in immunocompromised patients, particularly human immunodeficiency virus (HIV)-positive patients, but CM may also occur in apparently immunocompetent individuals. Outcome analyses have been performed in such patients but, due to the high prevalence of HIV infection worldwide, CM patients today may be admitted to hospitals with unknown HIV status, particularly in underdeveloped countries. The objective of this multicenter study was to analyze all types of CM cases in an aggregate cohort to disclose unfavorable outcomes...

MRAP is highly expressed in adrenal gland and adipose tissue. In adrenal cells, MRAP is essential for ACTH-induced activation of the cAMP/PKA pathway by melanocortin 2 receptor (MC2R), leading to glucocorticoid production and secretion. Although ACTH was known to stimulate PKA-dependent lipolysis, the functional involvement of MRAP in adipocyte metabolism remains incompletely defined. Herein, we found that knockdown or overexpression of MRAP in 3T3-L1 adipocytes reduced or increased ACTH-induced lipolysis, respectively...

Diabetes mellitus is a disease that affects glucose homeostasis. The World Health Organization informs that there are over 347 million people in the world with diabetes. The diagnosis and characterization of glucose homeostasis in different metabolic conditions are subjects of great importance with high clinical impact. There are many mathematical models that describe the gluco-regulatory system in detail. However, the use of these models is limited because they have a large number of mathematical equations and parameters and they require complex methodologies to estimate of them...

BACKGROUND: Patients with type II diabetes mellitus (T2DM) often have hypercholesterolemia, and their serum low-density lipoprotein cholesterol (LDL-C) levels are not always well-controlled even by statin treatment. The glucose-lowering glucagon-like peptide-1 receptor agonists (GLP-1RAs) are reported to change the lipid profiles in T2DM patients, but their effects have been unclear. OBJECTIVE: We examined whether GLP-1RAs affect serum cholesterol levels in T2DM patients with/without statin treatment...

AMOT has been identified as a YAP interactor. However, how AMOT regulates YAP remains unclear and controversy. Here, we identified that besides YAP, AMOT was another Hippo signaling core factor which could be O-GlcNAcylated. Moreover, high glucose (HG) was able to enhance the expression and O-GlcNAcylation of AMOT. We also found that HG stimulated nuclear accumulation, transcription activity, interaction with transcription factor and transcription of target genes of YAP via AMOT, while AMOT acted as a suppressor of YAP in normal glucose level...

REVIEW
Sebastião Freitas de Medeiros
BACKGROUND: Polycystic ovary syndrome (PCOS) is a complex condition with high risk for dyslipidemia, dysglycemia, venous thromboembolism, cardiovascular disease and metabolic syndrome. Because the combined oral contraceptive (COC) use has also been associated with impaired fasting glucose, insulin resistance and increased risk of thromboembolism disease, it is rationale to think that the combination of oral contraceptive and PCOS could make it worse or increase the risks. OBJECTIVE: To examine the current data regarding potential additional risks and benefits of contraceptive use, highlights the major gap in knowledge for designing future studies and, when possible, suggests an adequate COC formulation for a determined PCOS phenotype...

BACKGROUND/AIMS: Ischemia is one of the main causes of the high rate of absorption of transplanted autologous fat. Autophagy allows cells to survive by providing energy under starvation. Rapamycin has been found to play a role in promoting autophagy. In this study, we investigated whether rapamycin participates in the survival and adipogenesis of ischemia-challenged adipose-derived stem cells (ADSCs) by regulating autophagy. METHODS: Before the cells were exposed to oxygen-glucose deprivation (OGD), a simulated ischemic microenvironment, the level of autophagy was reduced or increased by lentiviral transfection with short hairpin RNA targeting microtubule-associated protein 1-light chain 3 gene (shRNA-LC3) or treatment with rapamycin, respectively...

Breast cancer is one of the major causes of death in the USA. Cancer cells, including breast, have high glycolysis rates to meet their energy demands for survival and growth. Vitamin D3 (VD3) is important for many important physiological processes such as bone mineralization, but its anticancer role is yet to be proven. We find that VD3 treatment significantly down-regulates glycolytic enzymes and genes and decreases glucose uptake - for both lowly metastatic MCF-7 and highly metastatic MDA-MB-231 (MB231) breast cancer cells...

Synechocystis sp. PCC 6803 is a widely used model cyanobacterium, whose substrains can vary on both genotype and phenotype levels. Previously described phenotypic variations include ability of mixotrophic growth, ability of movement on agar plates and variations in pigments composition or cell size. In this study, we report for the first time significant variation among Synechocystis substrains in complex cellular traits such as growth rate, photosynthesis efficiency, cellular dry weight and cellular composition (including protein or carbohydrates content)...

Abelmoschus esculentus (AE), a commonly consumed vegetable, is well-known for its anti-hyperglycemic effects. However, few scientific reports have identified its targets because mucilage increases the difficulty of manipulation. We recently reported extraction steps to obtain subfractions of AE, which were found to attenuate the adverse effects of high glucose and fatty acid in vitro. In this study, we used modified extraction steps and type 2 diabetic rats to explore whether AE subfractions can improve the metabolic disturbances caused by insulin resistance in vivo...

Carbon nanomaterials have emerged as suitable supports for enzyme immobilization and stabilization due to their inherently large surface area, high electrical conductivity, chemical stability and mechanical strength. In this paper, carbon nano-onions (CNOs) were used as supports to immobilize alkaline phosphatase, horseradish peroxidase and glucose oxidase. CNOs were first functionalized by oxidation to generate carboxylic groups on the surface followed by the covalent linking of the using a soluble carbodiimide as coupling agent...
