The role of metalloproteinases and their inhibitors in adipose tissue inflammation and the development of type 2 diabetes

Fenech Matthew , Swingler Tracey , Gavrilovic Jelena , Sampson Mike , Turner Jeremy

The development of insulin resistance and type 2 diabetes mellitus (T2DM) in obesity involves (a) adipose inflammation, and (b) restricted adipose expansion with ectopic lipid deposition. Metalloproteinases (MPs) and tissue inhibitors of metalloproteinases (TIMPs) constitute a key regulatory system in inflammation and tissue remodelling. Evidence of MP and TIMP involvement in adipose tissue inflammation and modulation of adipose expansion is currently restricted to work in adi...

Epigenetic changes in hypothalamic energy regulating pathways implicated in programming of adult offspring

Begum Ghazala , Stevens Adam , Jaquiery Anne , Challis John , Bloomfield Frank , White Anne

There is increased prevalence of obesity and diabetes in offspring from mothers subjected to adverse conditions during pregnancy. Our previous work demonstrated that maternal undernutrition causes epigenetic changes in hypothalamic energy regulating networks in foetal sheep. We hypothesise that these changes will persist into adulthood. Therefore, this study examined the impact of maternal undernutrition on epigenetic and mRNA expression of hypothalamic regulators of energy ba...

Association between low concentration of serum sex hormone binding globulin and insulin resistance is independent of adiposity, but may be attributable to fasting insulin concentration

Wallace Ian , McEvoy Claire , Hamill Lesley , Woodside Jayne , Ennis Cieran , Bell Patrick , Young Ian , McKinley Michelle , Hunter Steven

Introduction: Recently low circulating levels of sex hormone binding globulin (SHBG) have been shown to be a strong predictor of the risk of developing type 2 diabetes. Genetic studies suggest that this may be a primary causal abnormality and the mechanism may relate to effects on insulin resistance.Methods: Insulin resistance was assessed using a two-step euglycaemic hyperinsulinaemic clamp (EHC) in 87 (59 male and 28 post-menopausal female) overweight ...

Cholestatic pregnancy has a gender-specific programming effect in mouse adult offspring

Papacleovoulou Georgia , Abu-Hayyeh Shadi , Nikolopoulou Evanthia , Owen Bryn , Nikolova Vanya , Jansen Eugene , Knisely Alex , Williamson Catherine

Alterations in maternal metabolism can programme disease in the offspring. Intrahepatic cholestasis of pregnancy is a liver disease of pregnancy that presents with increased maternal serum bile acids (BA) and dyslipidaemia. We aimed to investigate whether cholestatic pregnancy affects the subsequent health of the offspring. We developed a cholestatic mouse model by supplementation of a normal chow (NC) diet with 0.5% cholic acid during pregnancy. 18 weeks old female and male o...

Pravastatin does not prevent macrosomia in pregnancy complicated by maternal diabetes

Nadif Raja , Baker Bernadette , Lewis Renshall , Dilworth Mark , Sibley Colin , Baker Philip , Davidge Sandra , Aplin John , Westwood Melissa

Pregnancy complicated by pre-existing or gestational diabetes is associated with increased risk of maternal and fetal mortality and morbidity. The most common complication, macrosomia, occurs during the third trimester of pregnancy as a result of abnormal placental growth and increased transfer of nutrients to the fetus. We have previously demonstrated using an explant model of human placenta, that statins have the potential to limit placental growth. In this study we tested t...

The effect of specific micronutrients on appetite

Greenwood Hannah , McGavigan Anne , Ghatei Mohammad , Bloom Stephen , Murphy Kevin

Ingested protein has a greater satiating effect than other macronutrients. The underlying mechanism is unknown, but it has been shown that protein induces greater increases in anorectic gut hormone levels than carbohydrate or fat. It was hypothesised that these effects could be mediated by specific amino acids comprising the protein. We therefore examined the effects of specific amino acids on food intake and gut hormone release. Fasted male Wistar rats received an oral gavage...

Arterial stiffening and increased pressure wave reflection in HIV recipients of highly active antiretroviral therapy (HAART): the influence of insulin sensitivity, adipokines and autonomic nerve function

Bunce Susan , Sinclair Daivd , Smith Jamie

Background: Treatment of HIV patients with antiretroviral therapies may confer an increased cardiovascular risk, possibly mediated through metabolic perturbations induced by these therapies. We sought to determine whether large arterial stiffening, an early marker and predictor of cardiovascular disease, occurs in HIV recipients of HAART, and if so the plausible mechanisms involved.Methods: In this case-control analysis, 56 HIV subjects (mean age 46 &#17...

Effect of secreted frizzled-related protein 2 (sFRP2) from adipose tissue on pancreatic cell function.

Bujalska Iwona , Rabbitt Elizabeth , Stewart Paul

Background: The detrimental effect of excessive obesity on insulin resistance has been well established. The expansion of adipose tissue is closely dependent on two processes: adipogenesis and angiogenesis and the Wnt signalling pathway has been reported to affect both. In adipose tissue the Wnt signalling pathway functions in a converse manner: increasing commitment of mesenchymal stem cells to preadipocytes and inhibiting differentiation of preadipocytes to mature adipocytes...

Saturated fatty acid-activated macrophage-conditioned medium activates MAP kinases and impairs insulin sensitivity in C2C12 myotubes

Talbot Nicola , Wheeler-Jones Caroline , Cleasby Mark

Skeletal muscle is the principal site for insulin-stimulated glucose disposal but its ability to utilise glucose is diminished by insulin resistance associated with obesity and consequent elevations of free fatty acids (FFAs). Chronic sub-clinical inflammation, characterized by increased macrophage infiltration into obese adipose tissue is a hallmark of the insulin resistance syndrome. However, little is known about the potential role of muscle macrophages in mediating local e...

Reducing glucocorticoid action improves hyperinsulinaemia but not insulin-sensitive glucose or fatty acid turnover in patients with type 2 diabetes with and without fatty liver

Macfarlane David , Raubenheimer Peter , Bastin Mark , Marshall Ian , Andrew Ruth , Walker Brian

Background & Aims: Observational studies implicate glucocorticoid excess, principally due to altered steroid metabolism in target tissues, in both the insulin resistance and liver fat accumulation that accompanies type 2 diabetes. To test the contribution of glucocorticoid signalling to metabolic dysfunction we blocked cortisol secretion (with metyrapone) and action (with the GR antagonist mifepristone) simultaneously in men with type 2 diabetes ± fatty liver.<p c...

Expression of genes regulating mitochondrial fusion and fission in human adipose tissue are influenced by adiposity and bariatric surgery

McCarthy Ciara , Voyias Philip , Antonysunil Adaikala , McGee Kirsty , Harte Alison , Saravanan Ponnusamy , Kyrou Ioannis , Kumar Sudhesh , McTernan Philip , Tripathi Gyanendra

Mitochondria are essential for synthesising ATP required for cellular metabolism. In response to changes in their cellular environment, mitochondria are able to alter their morphology and abundance through the balance of “fusion” and “fission” events. The aim of this study was to profile the expression of mitochondrial genes in the abdominal subcutaneous (AbSc) adipose tissue (AT) of lean, obese and Type 2 Diabetes Mellitus (T2DM) individuals and determine ...

The effects of bariatric surgery on the endoplasmic reticulum stress pathway in human adipose tissue

Voyias Philip , McCarthy Ciara , Antonysunil Adaikala , Kumasaiyai Warunee , Al Naji Fadi , McGee Kirsty , Harte Alison , Saravanan Ponnusamy , Kyrou Ioannis , McTernan Philip , Tripathi Gyanendra

Background: Endoplasmic reticulum (ER) stress in adipose tissue (AT) is critical to the initiation and integration of inflammation and insulin signalling pathways in obese and type 2 diabetes mellitus (T2DM) patients. It induces an unfolded protein response (UPR) to restore functional integrity which leads to upregulation of three master regulators of ER; PKR-like ER-regulated kinase (PERK), inositol requiring enzyme1α (IRE1α) and activating transcription factor6 (AT...

Ablation of Peptide YY cells in adult mice reveals a role in beta-cell maintenance

Sam Amir , King Aileen , Hostomska Klara , Persaud Shanta , Liu Bo , Ghatei Mohammad , Bloom Stephen , Bewick Gavin

In the pancreas, PYY is expressed in a subpopulation of non-beta cells in the islets of Langerhans. The role of PYY-expressing cells in the adult pancreas is unknown. We generated a mouse model in which administration of diphtheria toxin (DT) produced specific ablation of PYY-expressing cells in the colon, pancreas and brainstem. Interestingly, DT administration to adult mice resulted in severe hyperglycaemia associated with significant loss of pancreatic insulin and disrupted...

Heterozygosity in the leptin receptor gene predisposes to placental and fetal overgrowth

Nadif Raja , Renshall Lewis , Baker Bernadette , Dilworth Mark , Sibley Colin , Aplin John , Westwood Melissa

Mutations in the leptin receptor gene (Lepr) occur spontaneously in humans and mice and are linked to early onset obesity and diabetes. Mice heterozygous for a signalling-deficient receptor (db/+) are widely used as a model of gestational diabetes that results in fetal macrosomia, but the contribution of the fetal genotype has yet to be evaluated. Eight week old wild type (wt) females (n=8) were mated to db/+ males and db/+ females (n=10) were mated to wt males i...

Circadian dietary rhythms: association with the metabolic syndrome in the 1946 British birth cohort

Almoosawi Suzana , Prynne Celia , Hardy Rebecca , Lennox Alison

Epidemiological evidence suggests that timing of eating and nutrient composition of meals can predict obesity development. However, few studies have examined the association between nutrient composition of eating occasions and prevalence of metabolic syndrome. We examined the association between time-of-day and nutrient composition of eating occasions and long-term development of metabolic syndrome in the MRC National Survey of Health and Development (1946 British birth cohort...

Endothelial function, the renin-angiotensin-aldosterone axis (RAAS) and hypertension: the therapeutic role of potassium supplementation

Graham Una , McCance David , Young Ian , Mullan Karen

There is limited evidence on the effect of potassium (K+) supplementation on endothelial function. Three studies suggest a beneficial effect in healthy volunteers and mild hypertensives. However potassium increases aldosterone due to a direct effect on the adrenal gland and there is evidence that aldosterone excess is detrimental to cardiovascular health. We therefore aimed to determine the effect of potassium supplementation on endothelial function in patients with...

Testosterone Inhibits Key Enzymes of Fatty Acid Synthase and Protects Against Hepatic Steatosis in the Tfm Mouse

Kelly Daniel , Brooke Jonathan , Muraleedharan Vakkat , Akhtar Samia , Channer Kevin , Jones Hugh

Objectives: A clinical feature of insulin resistance is the development of fatty liver (hepatic steatosis). Testosterone deficiency is common in men with type-2 diabetes and is associated with insulin resistance. The testicular feminised mouse (Tfm) exhibits a non-functional androgen receptor (AR) and low circulating testosterone. We have previously shown that a high-cholesterol diet promotes hepatic steatosis in Tfm mice, and testosterone replacement therapy (TRT) attenuates ...

Investigation of the cellular basis of severe hypoglycaemia associated with the AKT2 p.Glu17Lys mutation

Minic Marina , Challis Ben , Rocha Nuno , Huang-Doran Isabel , Barroso Ines , O'Rahilly Stephen , Semple Robert

AKT serine-threonine kinases are critical mediators of both growth and metabolic actions of insulin. AKT2 is believed to exert predominantly metabolic effects, while AKT1 has been more strongly implicated in growth. We have recently reported that the de novo AKT2 p.Glu17Lys mutation produces a sporadic syndrome of severe persistent hypoinsulinaemic hypoglycaemia associated with left-sided hemihypertrophy. Glucose requirements in affected patients are far lower than seen in hyp...

The adipocyte as an active source of PLA2 isoforms influenced by adiposity, depot specificity and Type 2 Diabetes Mellitus

Kumsaiyai Warunee , Harte Alison , Saravanan Ponnusamy , Kyrou Ioannis , Aldaghri Nasser , Al-Attas Omar , Kumar Sudhesh , Tripathi Gyanendra , McTernan Philip

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a member of the phospholipase A2 super family of enzymes that hydrolyse phospholipids, and is upregulated in arterial inflammation, obesity and cardiovascular disease. Secreted soluble Lp-PLA2 (sPLA2) increases arterial inflammation in addition to cytosolic calcium dependent PLA2 (cPLA2) and calcium independent PLA2 (iPLA2). These studies examined the influence of adipose tissue (AT) depots (abdominal subcutaneous (Abd Sc), ...

Association between rs1801260 of the circadian gene CLOCK and lipid and glucose metabolism in women with Polycystic Ovary Syndrome

Pernicova Ida , Akinci Baris , Prasai Madhu , Baxter Paul , Scott Eleanor

Introduction: The circadian clock controls numerous aspects of mammalian physiology across the 24 hour day, including lipid and glucose metabolism. Disruption of the core circadian gene CLOCK is associated with the development of obesity, diabetes and the metabolic syndrome in mice. Women with Polycystic Ovary Syndrome (PCOS) are at increased risk of developing diabetes, dyslipidemia and the metabolic syndrome. The aim of the present study was to investigate the relationship o...

Insulin degludec has a two-fold longer half-life and a more consistent pharmacokinetic profile compared with insulin glargine

Heise Tim , Hovelmann Ulrike , Nosek Leszek , Bottcher Susanne , Granhall Charlotte , Haahr Hanne

Insulin degludec (IDeg) is an ultra-long-acting basal insulin that forms soluble multi-hexamers after injection. These release monomers slowly and continuously to produce a flat and stable glucose-lowering effect. We describe the pharmacokinetic and pharmacodynamic properties of IDeg compared with insulin glargine (IGlar) under steady-state conditions in patients with type 1 diabetes (T1D). This was a randomised, double-blind, two-period crossover study in 66 patients with T1D...

Consumption of ground green coffee influences 11B-HSD1 activity and improves blood pressure and body composition in healthy individuals

Revuelta-Iniesta Raquel , Al-Dujaili Emad

Background: We have recently shown that consumption of green coffee bean extract rich in chlorogenic acid reduces blood pressure and urinary free cortisol levels1. Increased 11β HSD1 (Hydroxysteroid dehydrogenase type1) activity is implicated in the development of obesity, cardiovascular disease and diabetes. The aim of this study was to compare the effects of consuming green (GC) and black (BC) coffees on cardiovascular, anthropometrical markers and urinary free glucocor...

Investigating the sites and mechanisms by which peripheral prokineticin 2 administration reduces food intake and body weight in mice

Beale Kylie , Gardiner James , Bewick Gavin , Hostomska Klara , Patel Neekhil , Hussain Syed , Ebling Francis , Jethwa Preeti , Prosser Haydn , Ghatei Mohammad , Bloom Stephen , Dhillo Waljit

Prokineticin 2 (PK2) is a neuropeptide expressed in hypothalamic nuclei involved in the regulation of energy homeostasis, and has been shown to acutely reduce food intake in rodents. PK2 binds to and activates two G protein-coupled receptors, the PK receptor 1 (PKR1) and the PK receptor 2 (PKR2). We aimed to determine the sites and receptors which mediate the anorectic effects of peripherally administered PK2 within the CNS. We investigated neuronal activity in the hypothalamu...

Maternal Obesity in Human Pregnancy is Associated with Altered Placental Expression of Key Genes in Fetal Growth During the First Trimester, but not at Term

O'Reilly James , Drake Amanda , Jones Rebecca , Critchley Hilary , Riley Simon , Seckl Jonathan , Reynolds Rebecca

Background: Maternal obesity during pregnancy is associated with adverse effects on fetal growth and development. As the placenta is a key organ regulating fetal growth, we hypothesized that maternal obesity is associated with altered placental expression and DNA methylation of genes regulating fetal growth and glucocorticoid metabolism and aimed to investigate this in first trimester (F; <12 weeks gestation) and term (T;>37 weeks gestation) placental tissues.<p cl...

The role of metabolic dyslipidaemia in screening for impaired glucose regulation in polycystic ovary syndrome

Aye Myint M , Kahal Hassan , Smith H , Sandeman D , Kilpatrick Eric , Atkin S

Background: Women with polycystic ovary syndrome (PCOS) are commonly associated with insulin resistance, metabolic syndrome and a family history of diabetes mellitus (DM). They are therefore at risk of diabetes and dyslipidaemia. Diabetes UK (2006) recommends screening for diabetes in PCOS patients who have a body mass index (BMI) ≥30. The recommended test is fasting plasma glucose (FPG). We therefore investigated 55 PCOS patients and 33 healthy volunteers to test the hy...

Annexin A1, an anti-inflammatory regulator, is expressed in human adipocytes

Kosicka-Knox Anna , Cunliffe Adam , Mackenzie Richard , Zariwala Mohammed , Renshaw Derek

Annexin A1 (AnxA1), an endogenous glucocorticoid regulated protein, is a pivotal homeostatic regulator of the magnitude of the inflammatory response. We have previously demonstrated that plasma AnxA1 protein is significantly inversely correlated with waist to hip ratio (P=0.017). Given that low-level systemic inflammation is seen in metabolic syndrome-associated chronic pathologies, here, we investigate if AnxA1 is also involved in the regulation of adipose tissue infla...

Dual effect of arachidonic acid on peroxisome proliferator-activated receptor γ (PPARγ)-dependent action in 3T3-L1 adipocytes

Nikolopoulou Evanthia , Parker Malcolm , Christian Mark

Dietary fat has been correlated with obesity since it induces the proliferation and differentiation of pre-adipocytes. However it has become clear that the effect of fat on human health depends on the composition and the nature of fatty acids. Arachidonic acid (AA) is a major omega-6 polyunsaturated fatty acid (PUFA) with a controversial role in adipocyte differentiation. We investigated the effect of a brief AA exposure on pre-adipocyte differentiation. We show that a short t...

Superinduction of leptin mRNA in mouse hypothalamic neurons

Imran Ali , Brown Russell , Wilkinson Diane , Wilkinson Paul , Wilkinson Michael

Introduction: We previously reported the novel finding that leptin, and several other fat-derived hormones (adipokines), is expressed and regulated in rat hypothalamus (1). Subsequently leptin (ob) mRNA was found in human, sheep and pig brain, but was surprisingly undetectable in mouse brain. In the present experiments we used a mouse hypothalamic neuronal cell line to investigate possible inhibitory mechanisms that may prevent mouse neurons from expressing ob mRNA. These incl...

A novel genetic mutation causing MODY 1

Brady Sally , Edwards Mark

Maturity-onset diabetes of the young (MODY) is a group of autosomal dominant inherited disorders causing non-insulin-dependent diabetes. MODY is the most common form of monogenic diabetes, accounting for 1-2 % of diabetes in Europe; however it is often misdiagnosed as Type 1 or 2 Diabetes. MODY is caused mainly by mutations in the GCK, HNF1A or HNF4A genes, the two former accounting for 70% of all cases. A molecular genetic diagnosis is important as it can directly alter patie...

Salt sensitive blood pressure in glucocorticoid receptor deficient mice

Richardson Rachel , Evans Louise , Moorhouse Rebecca , Chapman Karen , Kenyon Christopher , Bailey Matthew

Salt-sensitive hypertension is a major risk factor for cardiovascular morbidity. Humans and mice with glucocorticoid receptor haploinsufficiency (GR+/−) are hypertensive, which in mice reflects activation of the renin-angiotensin-aldosterone system. Furthermore, glucocorticoid receptor (GR) gene polymorphisms associate with increased cardiovascular disease risk. Here we investigated the effect of dietary salt intake on blood pressure, heart and kidney in GR+/− mice...

24-hour urinary glucocorticoid metabolites are associated with hyperinsulinaemia independent of BMI in patients with the polycystic ovary syndrome

O'Reilly Michael , Hazlehurst John , Lebbe Marie , Stewart Paul , Tomlinson Jeremy , Arlt Wiebke

Polycystic ovary syndrome (PCOS) is a triad of insulin resistance, hyperandrogenism and anovulation. PCOS is associated with increased adrenocortical drive and 5alpha-reductase activity, which may have adverse metabolic consequences. Here we analysed the relationship of urinary androgen and glucocorticoid metabolite excretion with markers of insulin resistance in a large PCOS cohort. We compared results from 127 PCOS patients fulfilling Rotterdam diagnostic criteria with 100 B...

Epigenetic signature of endothelial cells and muscle tissue in the diabetic models of limb ischemia

Mitic Tijana , Floris Ilaria , Meloni Marco , Madeddu Paolo , Emanueli Costanza

Endothelial cells (ECs) may display distorted epigenetic features in diabetes mellitus (DM) but this has not been investigated under combined conditions of diabetes and limb ischemia. Initial screening for histone H3 and H4 trimethylation (me3) and panacetylation of lysine residues (causing transcriptional repression and activation) were conducted using two models of hyperglycemia and ischemia. Human umbilical vein ECs (HUVECs) were cultured in EGM2 or EBM2 media (low growth f...

Post-partum gestational diabetes management: is fasting blood glucose sufficient?

Narayanaswamy Shakunthala , Ahlquist James

NICE guidelines (2008) recommend that patients with gestational diabetes (GDM) should no longer have post-partum review with glucose tolerance test (GTT), but that fasting blood glucose is sufficient. We have undertaken a retrospective study of post-partum GTT in patients with GDM, to examine whether the 2 hour glucose value adds useful additional information. Notes of 208 patients with GDM in 2003–2008 were reviewed, and the results of post-partum GTT were collected. 175...

Circadian clock gene BMAL1 is associated with blood pressure but not autonomic function in man

Pernicova Ida , Prasai Madhu , Maqbool Azhar , Robert West , Mary David A.S.G. , Scott Eleanor

Introduction: The circadian clock controls numerous aspects of mammalian physiology across the 24 hour day. The suprachiasmatic nucleus (SCN) is the “master clock” which coordinates the peripheral clocks in the body, including the pineal clock that receives SCN input via a multisynaptic noradrenergic pathway. Murine studies have shown a role for the core clock gene BMAL1 in the regulation of blood pressure. Selected haplotypes of BMAL1 have previously been associated...

Retention of Leukocytes in the Diabetic Wound Environment

Charnock Jayne , Gallego Enrique , Mace Kimberly

Inadequate wound repair, observed in 15% of diabetics, leads to a chronic wound phenotype and is the leading cause of non-traumatic amputation in the developed world today. Injury induces recruitment of bone marrow-derived cells (BMDCs) to the wound in response to chemoattactant signals, which then contribute to the repair and regeneration process, initially through their role in the inflammatory response. Both granulocytes and monocytes are fundamental at this early stage, bu...

Effect of Testosterone on Cholesterol Synthesis and Efflux in the Liver of the Testicular Feminised (Tfm) Mouse

Kilby Elizabeth , Kelly Daniel , Akhtar Samia , Muraleedharan Vakkat , Channer Kevin , Jones Hugh

Objectives: Symptomatic hypogonadism is common in obese men with type-2 diabetes (T2DM) and metabolic syndrome (MetS), and is now an independent risk factor for cardiovascular disease. Testosterone replacement therapy (TRT) improves cholesterol metabolism in hypogonadal men with T2DM and/or MetS. We have previously shown that a non-functional androgen receptor (AR) and low levels of circulating testosterone in the testicular feminised (Tfm) mouse is associated with elevated ch...

Exposure to elevated glucose prior to differentiation re-programs the cellular secretory pathway in fetal hepatocytes

Gardner David , Wells Catherine , Welham Simon

Various programming stimuli have been postulated to permanently influence fetal development with the common result that offspring exhibit differing degrees of insulin resistance. We set out to establish whether protein restriction, high glucose, glucocorticoid or alcohol exposure might exert their effects directly using a derived population of fetal hepatocytes. Cells were isolated from fetal mouse livers (n=10) at embryonic day 12. Fetal livers were rinsed in phosphate...

Chronic or intermittent exposure to Oleic acid (MUFA) induces a greater NFκB activated inflammatory response than Eicosapentaenoic acid (PUFA) in differentiated human adipocytes

Piya Milan , Harte Alison , McGee Kirsty , Reddy Narendra , Tripathi Gyanendra , McTernan Philip , Kumar Sudhesh

Replacement with mono-unsaturated fatty acids (MUFA) or poly-unsaturated fatty acids (PUFA) reduces inflammation in the pre-diabetic subjects but the benefits are unclear in subjects with type 2 diabetes mellitus (T2DM). Our aim was to investigate whether saturated fatty acids (SFA), MUFA and PUFA produce a similar adipocyte inflammatory response, which may explain the rationale for maintained systemic inflammation noted in subjects with T2DM. The differentiated human preadipo...

Effects of Syzygium aromaticum-derived maslinic acid on blood glucose of streptozotocin induced-diabetic rats

Mkhwanazi Blessing , Masola Bubuya , van Heerden Fanie , Musabayane Cephas

Available evidence suggests that Syzygium spp ethyl acetate extract solubles (EAS) contain triterpene constituents; oleanolic acid (OA), ursolic acid (UA) and methyl maslinate with hypoglycaemic properties. The effects of maslinic acid (MA) on blood glucose in type 1 diabetes mellitus are, however, unclear. Accordingly, we evaluated anti-hyperglycaemic effects of MA in streptozotocin (STZ)-induced diabetic rats, an experimental model for type 1 diabetes. Extraction and fractio...

Severe Acute Mountain Sickness and Brain Natriuretic Peptide in Humans

Stacey Mike , Mellor Adrian , Boos Christopher , Smith Chris , Hooper Tim , Jo Yarker , Hodkinson Pete , Green Nic , Woods David

We have previously reported that exercise at high altitude (HA) led to a significant increase in brain natriuretic peptide (BNP) levels. In contrast two other publications have reported no change in resting BNP at HA. We therefore measured BNP and Lake Louise (LL) Acute Mountain Sickness (AMS) scores in a further 20 subjects at rest in Kathmandu (Kat; 1300 m); and following exercise and at rest at 4270 m and 5150 m. Compared with the baseline BNP level at Kat (9.2+/−2 pg...

Haemoglobin A1c in diagnosis of impaired glucose regulation in polycystic ovary syndrome

Aye Myint M , Kahal H. , Hooson F. , Sathyapalan T. , Atkin S. , Kilpatrick E.

Introduction: Impaired glucose regulation (IGR) is usually defined as impaired fasting glucose (IFG, fasting plasma glucose (FPG) is between 6.1 to 6.9 mmol/L) and/or impaired glucose tolerance (IGT, 2 hour postprandial glucose (PPG) is 7.8 to 11 mmol/L). More recently, a haemoglobin A1c (HbA1c) ≥ 42 but <47 mmol/mol has been suggested to indicate an increased diabetes risk. Women with polycystic ovary syndrome (PCOS) are strongly associated with insulin resistance a...

Unique roles of CRH-Rs controlling adipocyte biology and transdifferentiation

Lu Buyu , Markovic D. , Pessin Jeff , Lehnert Hendric , Grammatopoulos Dimitris

In addition to well established role in coordinating mammalian adaptive responses to stressful stimuli, the family of “stress” peptides that includes corticotropin releasing hormone (CRH) and urocortins (Ucns) are emerging as important regulators of the homeostatic mechanisms regulating energy balance and metabolism. CRH acting through specific G-protein coupled receptors, CRH-R1 and R2 can target multiple peripheral tissues such as skeletal muscle and adipose tissue...

Regulation of Hypothalamic Resistin and FIAF gene expression by Rosiglitazone and All-Trans Retinoic Acid (ATRA)

Brown Russell , Imran Ali , Wilkinson Michael

Introduction: Adipokines, such as resistin and fasting-induced adipose factor (FIAF), are implicated in the regulation of insulin sensitivity and regulated by nuclear receptors like peroxisome proliferator activated receptor gamma (PPARγ), and retinoic acid receptor alpha (RARα). Primarily expressed in murine fat, we also showed that these adipokines are expressed in the mouse hypothalamus, as well as in N-1 hypothalamic neurons. We hypothesized that rosiglitazone (R...

A comparison of the neuronal populations within the nucleus tractus solitarius activated by peripheral administration of glucagon, GLP-1 and oxyntomodulin

Parker Jennifer , Tadross John , Field Benjamin , Minnion James , Bloom Stephen

The preproglucagon derived peptides glucagon, glucagon-like peptide-1 (GLP-1) and oxyntomodulin are all known to inhibit appetite and have been previously shown to activate the nucleus tractus solitarius (NTS) in the brainstem. The NTS is involved in the processing of signals transmitted from the periphery to the brain via the vagus nerve. The anorectic effects of peripherally administered glucagon and GLP-1 have been shown to be diminished or ablated by subdiaphragmatic vagot...

A putative role for amino acids in appetite regulation

McGavigan Anne , Greenwood Hannah , Kinsey-Jones James , Ghatei Mohammed , Bloom Stephen , Murphy Kevin

Obesity is a major worldwide health problem with limited treatment options. Recent research has highlighted the importance of gastrointestinal (GI) nutrient sensing in the regulation of food intake and metabolism. Protein as a macronutrient induces the strongest feeling of satiety per calorie. However, different types of protein have varying effects on appetite, suggesting protein induced satiety may be due to the specific amino acids generated by protein digestion. We have id...

Renal sodium dependent glucose co-transporter 2 (SGLT2): A neoteric target for treatment of type2 diabetes mellitus

Ahmed Danish

Contemporary therapies to trim down the hyperglycaemia in type 2 diabetes mellitus (T2DM) generally involve insulin-dependent mechanisms and lose their effectiveness as pancreatic b-cell function decreases to a greater extent. Kidney emerges out as a novel and potential target to trim down the T2DM. The filtered glucose is reabsorbed principally through the sodium glucose co-transporter-2 (SGLT2), a low affinity transport system, which are present at the luminal surface cells ...
