The effects of Syzygium aromaticum derived oleanolic acid on glycogenic enzymes in streptozotocin induced-diabetic rats

Ngubane Phikelelani , Masola Bubuya , Musabayane Cephas

Diabetes mellitus is characterized by partial or total deficiency of insulin resulting in derangement of carbohydrate metabolism and a decrease in the activity of glycogenic enzymes resulting in depletion of liver and muscle glycogen. Accordingly, this study assessed the influence of OA on two key glycogenic enzymes of skeletal muscle and liver tissues in STZ-induced diabetic rats. We have, however, reported that the anti-hyperglycaemic effects of Syzygium aromaticum de...

Endoplasmic reticulum oxidoreductases and insulin folding

Rajpal Gautam , Liu Ming , Arvan Peter

Proinsulin makes three evolutionarily-conserved disulfide bonds, two of which connect the insulin B and A chains, and one intrachain bond within the A chain. In Type II diabetes mellitus, increasing evidence suggests that insulin-secreting pancreatic β cells show signs of endoplasmic reticulum (ER) stress and an increase in the presence of proinsulin with mispaired disulfide bonds. In addition, heterozygous expression of misfolded mutant proinsulin is known to cause autos...

Cabergoline prevents weight gain in patients evaluated for hyperprolactinaemia

Whyte Martin , Aziz Riaz , Pramodh Sesha , Aylwin Simon

Introduction: Food reward stimuli elevate dopamine levels in brain reward circuits. Decreased dopaminergic signalling may be involved in pathophysiological processes leading to obesity and D2 receptor antagonists (antipsychotics) are associated with a higher risk of obesity. One study has demonstrated an association between the use of a dopamine D2 agonist (bromocriptine) and weight-loss in patients with prolactinoma. We have investigated the effect of cabergoline on body weig...

Interactions between glucagon and GLP-1 in neuronal pathways affecting food intake

Parker Jennifer , Simpson Katherine , Minnion James , Field Ben , Ghatei Mohammad , Bloom Steve

Glucagon is released from α-cells in the pancreatic islets and is best known for its role in glucose homeostasis. Glucagon/GLP-1 receptor co-agonists have recently been shown to improve glucose homeostasis and reduce body weight in diet-induced obese mice. Glucagon receptor agonism increases energy expenditure while the GLP-1 receptor agonism prevents glucagon-induced hyperglycemia. Peripherally administered glucagon is also capable of reducing food intake, and glucagon n...

The effect of environmental enrichment on food intake, body weight and the HPA axis in laboratory rats

Beale Kylie , Harrison Eleanor , Smith Kirsty , Kerton Angela , Ghatei Mohammad , Bloom Steve , Murphy Kevin

Laboratory rats are commonly used to study energy homeostasis. To accurately record food intake or energy expenditure it is necessary to house rats individually, which can be stressful for social animals. Environmental enrichment may reduce stress and improve welfare in laboratory rodents. However, the effect of environmental enrichment on food intake and thus experimental outcome in rats is unknown. We aimed to determine the effect of environmental enrichment on food intake, ...

Plasma Annexin A1 (AnxA1) is inversely correlated with waist to hip ratio in healthy males

Kosicka-Knox Anna , Cunliffe Adam , Mackenzie Richard , Flower Rod , Renshaw Derek

The escalating public health problem represented by obesity has spurred multidisciplinary research into adipose tissue and importantly, the molecular biology of the adipocyte. Recent studies suggest that obesity related metabolic disorders are characterised by chronic mild inflammation as a result of adipocytokine production from fat tissue leading to dysregulation in the pro/anti-inflammatory systemic balance. Adipokines and pro-inflammatory markers are implicated in insulin ...

Characterisation of IGFBP1 molecular forms in healthy persons and patients with diabetes mellitus type 2 or hypoglycemia

Lagundzin Dragana , Nedic Olgica

Insulin-like growth factors (IGFs) and their binding proteins (IGFBPs) are involved in the regulation of glucose metabolism and metabolic disorders. IGFBP1 is the only IGF-binding protein that shows diurnal variation and is inversely correlated to the insulin level. IGFBP1 exists as non-phosphorylated protein and several phosphoforms. Phosphorylation affects the affinity of IGFBP1 for IGFs and, therefore, the ability to regulate IGF action. In the circulation IGFBP1 is associa...

Insulin-mediated pseudoacromegaly

Sam Amir , Tan Tricia , Meeran Karim

Patients with acromegaly have characteristic clinical features of soft tissue overgrowth. Both somatic and metabolic features of acromegaly are secondary to excess GH secretion and high circulating levels of insulin-like growth factor 1 (IGF1). However, an acromegaloid phenotype associated with severe insulin resistance is occasionally seen in the absence of biochemical hallmarks of acromegaly (insulin-mediated pseudoacromegaly). Here we present a case of ‘insulin-mediate...

Diet-induced obesity with metabolic dysfunction does not alter vascular function or remodelling in young C57Bl/6 mice

Dakin Rachel , Drake Amanda , Walker Brian , Seckl Jonathan , Hadoke Patrick

Obesity is associated with metabolic and vascular dysfunction. Many models have shown insulin resistance reduces endothelium-dependent vasodilation but this is also seen in obese subjects with normal glucose tolerance. There is also evidence of increased response to vascular injury in obese animals, although the mechanisms underpinning this are not fully understood. This study used a mouse model of diet-induced obesity (DIO) to address the hypothesis that obesity causes metabo...

Postprandial hypertriglyceridaemia in patients with polycystic ovary syndrome

Aye Myint M , Afolabi Paul R , Sathyapalan T , Wakil Ammar , Wootton S A , Sandeman Derek D , Kilpatrick Eric S , Atkin Stephen L

Background: Postprandial hypertriglyceridaemia is an independent risk factor for cardiovascular diseases. An acute rise of insulin in the fed state suppresses hormone-sensitive lipase to inhibit free fatty acids (FFAs) mobilisation from adipose tissue, and up-regulates lipoprotein lipase to increase FFAs influx to adipose tissue from chylomicrons, that is blunted in insulin resistant states. Polycystic ovary syndrome (PCOS) is associated with insulin resistance and cardiovascu...

The effect of glucose on hypothalamic neuropeptide Y release investigated using static incubation of hypothalamic explants

Hussain Syed Sufyan , Richardson Errol , Buckley Niki , Bewick Gavin , Bloom Stephen , Gardiner James

Attenuated glucoprivic feeding responses are a feature of hypoglycaemic unawareness in insulin-treated diabetes. Glucose alters the activity of hypothalamic neurones involved in regulating appetite. Arcuate nucleus (ARC) Neuropeptide Y (NPY) releasing neurones stimulate feeding. The identification of glucose-sensitive NPY releasing hypothalamic neurones suggests a strong role for these neurones in mediating changes in appetite induced by alterations of glucose. To gain a bette...

Chronic GH excess is associated with adenosine monophosphate-activated protein kinase (AMPK) threonine-172 phosphorylation changes that do not lead to changes in AMPK activity

Thomas Julia , List Edward , Kopchick John , Grossman Ashley , Korbonits Marta

GH influences multiple metabolic pathways. Excess GH (acromegaly) causes a distinct form of cardiomyopathy, which may progress to fulminant heart failure. AMPK is an energy conservation enzyme that modulates multiple areas of the cell stress response, inhibiting anabolism and promoting catabolism. AMPK is activated by phosphorylation at Thr172 and measurement of Thr172 phosphorylation is thought to correlate with enzyme activity. We investigated the influence of GH on cardiac ...
