Diabetes abolish cardioprotective effects of remote ischemic conditioning: evidences and possible mechanisms.

J Physiol Biochem 2019 Feb 7;75(1):19-28. Epub 2019 Feb 7.

Department of Pharmaceutical Sciences and Drug Research, Punjabi University, Patiala, 147002, India.

Diabetes mellitus significantly hampers the development of cardioprotective response to remote pre/post/perconditioning stimuli by impairing the activation of cardioprotective signaling pathways. Among the different pathways, the impairment in O-linked β-N-acetylglucosamine (O-GlcNAc) signaling and release of cardioprotective humoral factor may contribute in attenuating remote preconditioning-induced cardioprotection. Moreover, the failure to phosphorylate extracellular signal related kinase (ERK), phosphoinositide-3-kinase (PI3K), and AKT along with up-regulation of mechanistic target of rapamycin (mTOR) and decrease in autophagy may also attenuate remote preconditioning-induced cardioprotection.

Browning of white fat: agents and implications for beige adipose tissue to type 2 diabetes.

J Physiol Biochem 2019 Feb 30;75(1):1-10. Epub 2018 Nov 30.

Faculty of Biochemistry and Molecular Medicine, University of Oulu, Aapistie 7A, P.O Box 5400, 90014, Oulu, Finland.

Mammalian adipose tissue is traditionally categorized into white and brown relating to their function and morphology: while white serves as an energy storage, brown adipose tissue acts as the heat generator maintaining the core body temperature. The most recently identified type of fat, beige adipocyte tissue, resembles brown fat by morphology and function but is developmentally more related to white. The synthesis of beige fat, so-called browning of white fat, has developed into a topical issue in diabetes and metabolism research. Read More

Variations in adrenal gland medulla and dopamine effects induced by the lack of Irs2.

J Physiol Biochem 2018 Nov 26;74(4):667-677. Epub 2018 Oct 26.

Department of Physiology and Pharmacology, INCyL and IBSAL, Faculty of Medicine, University of Salamanca, Avda. Alfonso X el Sabio, s/n, E-37007, Salamanca, Spain.

The adrenomedullary chromaffin cells' hormonal pathway has been related to the pathophysiology of diabetes mellitus. In mice, the deletion of insulin receptor substrate type 2 (Irs2) causes peripheral insulin resistance and reduction in β-cell mass, leading to overt diabetes, with gender differences on adrenergic signaling. To further unravel the relevance of Irs2 on glycemic control, we analyzed in adult Irs2 deficient (Irs2) mice, of both sexes but still normoglycemic, dopamine effects on insulin secretion and glycerol release, as well as their adrenal medulla by an immunohistochemical and morphologic approach.

Department of Physiology, Faculty of Medicine in Hradec Kralove, Charles University, Simkova 870, 500 03, Hradec Kralove, Czech Republic.

The aim was to determine the effects of enhanced availability of branched-chain amino acids (BCAAs; leucine, isoleucine, and valine) on ammonia detoxification to glutamine (GLN) and protein metabolism in two types of skeletal muscle under hyperammonemic conditions. Isolated soleus (SOL, slow-twitch) and extensor digitorum longus (EDL, fast-twitch) muscles from the left leg of white rats were incubated in a medium with 1 mM ammonia (NH3 group), BCAAs at four times the concentration of the controls (BCAA group) or high levels of both ammonia and BCAA (NH3 + BCAA group). The muscles from the right leg were incubated in basal medium and served as paired controls. Read More

J Physiol Biochem 2018 Nov 23;74(4):623-633. Epub 2018 Jul 23.

INSERM U 1048 équipe 1, Institut des Maladies Métaboliques et Cardiovasculaires, Institut National de la Santé et de la Recherche Médicale (INSERM U1048), Université Paul Sabatier (I2MC-UPS), I2MC, Bât. L4, CHU Rangueil, BP 84225, 31432, Toulouse CEDEX 4, France.

Tyramine is found in foodstuffs, the richest being cheeses, sausages, and wines. Tyramine has been recognized to release catecholamines from nerve endings and to trigger hypertensive reaction. Thereby, tyramine-free diet is recommended for depressed patients treated with irreversible inhibitors of monoamine oxidases (MAO) to limit the risk of hypertension. Read More

Voluntary exercise opposes insulin resistance of skeletal muscle glucose transport during liquid fructose ingestion in rats.

J Physiol Biochem 2018 Aug 7;74(3):455-466. Epub 2018 Jun 7.

Exercise Physiology Laboratory, Department of Physiology, Faculty of Science, Mahidol University, Bangkok, 10400, Thailand.

We have recently reported that male rats given liquid fructose ingestion exhibit features of cardiometabolic abnormalities including non-obese insulin resistance with impaired insulin signaling transduction in skeletal muscle (Rattanavichit Y et al. Am J Physiol Regul Integr Comp Physiol 311: R1200-R1212, 2016). While exercise can attenuate obesity-related risks of cardiometabolic syndrome, the effectiveness and potential mechanism by which exercise modulates non-obese insulin resistance have not been fully studied.

PTRF acts as an adipokine contributing to adipocyte dysfunctionality and ectopic lipid deposition.

J Physiol Biochem 2018 Nov 4;74(4):613-622. Epub 2018 Jun 4.

Adipocyte and Fat Biology Laboratory (AdipoFat), Unidad de Investigación Traslacional, Instituto Aragonés de Ciencias de la Salud (IACS), Instituto de Investigación Sanitaria (IIS) Aragón, Hospital Universitario Miguel Servet, Isabel la Católica, 1-3, 50009, Zaragoza, Spain.

Adipose tissue (AT) expands under obesogenic conditions. Yet, when the growth exceeds a certain limit, AT becomes dysfunctional and surplus lipids start depositing ectopically. Polymerase I and transcription release factor (PTRF) has been proposed as a mechanism leading to a dysfunctional AT by decreasing the adipogenic potential of human adipocyte precursors. Read More

Physical training improves thermogenesis and insulin pathway, and induces remodeling in white and brown adipose tissues.

J Physiol Biochem 2018 Aug 25;74(3):441-454. Epub 2018 May 25.

Programa de Pós-Graduação em Saúde e Nutrição, Universidade Federal de Ouro Preto, Ouro Preto, MG, Brazil.

Physical training (PT) has been considered as a treatment in metabolic syndrome (MS), since it induces thermogenic activity in brown (BAT) and white (WAT) adipose tissues. We evaluated the therapeutic effect of PT on activity of WAT and BAT in rats with MS induced by high-fat diet (30% lard) for 13 weeks and submitted, for the last 6 weeks, to swimming or kept sedentary (SED) rats. MS-SED rats compared to control diet (CT-SED) rats showed low physical fitness and high levels of glucose, insulin, homeostasis evaluation of insulin resistance (HOMA-IR), homeostasis evaluation of the functional capacity of β-cells (HOMA-β), and blood pressure.

Regulatory roles of miR-155 and let-7b on the expression of inflammation-related genes in THP-1 cells: effects of fatty acids.

J Physiol Biochem 2018 Nov 22;74(4):579-589. Epub 2018 May 22.

Department of Nutrition, Food Science and Physiology; Centre for Nutrition Research, University of Navarra, c / Irunlarrea 1, 31008, Pamplona, Navarra, Spain.

The main aim of this investigation was to study the regulatory roles of let-7b and miR-155-3p on the expression of inflammation-associated genes in monocytes, macrophages, and lipopolysaccharide (LPS)-activated macrophages (AcM). A second goal was to analyze the potential modulatory roles of different fatty acids, including oleic, palmitic, eicosapentaenoic (EPA), and docosahexaenoic (DHA), on the expression of these miRNAs in the three cell types. This hypothesis was tested in human acute monocytic leukemia cells (THP-1), which were differentiated into macrophages with 2-O-tetradecanoylphorbol-13-acetate (TPA) and further activated with LPS for 24 h.

Department of General Surgery, Qilu Hospital of Shandong University, 107 Wenhua Xi Road, Jinan, 250012, People's Republic of China.

Ameliorated renal function has been reported after bariatric surgery, but the mechanisms underlying this phenomenon are not well-studied. To investigate whether the long non-coding RNA (lncRNA) MALAT1 mediates the amelioration of diabetic nephropathy after duodenal-jejunal bypass (DJB) surgery, rats were assigned randomly into four groups: diabetic (DM) group, DM with DJB surgery group, DM with sham surgery group, and healthy control group. Food intake, body weight, oral glucose tolerance test (OGTT), urine albumin excretion rate (UAER), and glomerular filtration rate (GFR) were measured and histological examination of renal sections was performed.

In this study, we compared the impact of administration of size-calibrated lipid emulsions prepared with either synthetic or natural emulsifiers on the post-absorptive plasma triacylglycerol responses in rats. We did this using four types of size-calibrated (10 μm diameter) and metastable (3 days) emulsions with 20% of an oleic acid-rich sunflower oil and 1% of either synthetic emulsifiers (Tween 80 or sodium 2-stearoyl-lactylate) or two proteins (β-lactoglobulin or sodium caseinate). An oral fat tolerance test was performed in fasted rats by oral administration of each of these formulations in continuous or emulsified forms. Read More

Effects of reactive oxygen species and interplay of antioxidants during physical exercise in skeletal muscles.

J Physiol Biochem 2018 Aug 1;74(3):359-367. Epub 2018 May 1.

Laboratory of Exercise Biochemistry and Physiology, Graduate Program in Health Sciences, Health Sciences Unit, Universidade do Extremo Sul Catarinense, Av. Universitária, 1105 Bairro Universitário, Criciúma, Santa Catarina, 88806-000, Brazil.

A large number of researches have led to a substantial growth of knowledge about exercise and oxidative stress. Initial investigations reported that physical exercise generates free radical-mediated damages to cells; however, in recent years, studies have shown that regular exercise can upregulate endogenous antioxidants and reduce oxidative damage. Yet, strenuous exercise perturbs the antioxidant system by increasing the reactive oxygen species (ROS) content. Read More

Bone is a dynamic organ, the bone-forming osteoblasts and bone-resorbing osteoclasts form the physiological basis of bone remodeling process. During pathological process of numerous inflammatory diseases, these two aspects are uncoupled and the balance is usually tipped in favor of bone destruction. Evidence suggests that the inflammatory destruction of bone is mainly attributed to oxidative stress and is closely related to mitochondrial dysfunction. Read More
