Investigating chemogenetic manipulation of spinal astrocytes within a high-fat diet-induced hyperglycaemic model during neuropathic pain development

Hardowar Lydia , Hulse Richard

The spinal cord dorsal horn acts as a hub for the modulation of sensory information, relying heavily upon the interplay of a heterogenous cell population (endothelial cells, astrocytes) with sensory neurons. We have identified in rodent models of hyperglycemic neuropathic pain that spinal microvasculature is damaged. A pathological hallmark of chronic pain is astrogliosis, acting as a potent source of inflammatory response and impacting vessel integrity and sensory neuronal ac...

3α-hydroxysteroid dehydrogenase type 1 (AKR1C4) is upregulated in patients with non-alcoholic fatty liver disease and AKR1C4 silencing improves hepatic metabolic phenotype in vitro

Tomlinson Jeremy , Nikolaou Nikolaos

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome. It represents a spectrum of disease, ranging from steatosis to non-alcoholic steatohepatitis, progressing to fibrosis, cirrhosis, and hepatocellular carcinoma. BAs, as well as their intermediary products (oxysterols), are metabolic modulators exerting their effects through activation of nuclear receptors (NRs), including the farnesoid-X- (FXR) and liver-X-receptors (LXR). Cruciall...

Transcriptional regulation of hepatic circadian rhythm and metabolism: determining the role of nutritional challenge

Tailor Aishwariya , Daniels Lorna

Metabolic fluxes in the liver demonstrate circadian rhythms. The hepatic circadian clock is a cell- autonomous protein network that governs the switch between the fasted and fed states via a series of transcriptional-translational feedback loops (TTLs). Diet is a powerful zeitgeber which can reprogramme the liver clock to follow eating schedule rather than the geophysical day-night cycle. Diet- induced circadian disruption has been implicated in the pathogenesis of common meta...

Neurotensin improves glucose tolerance via NtsR1-expressing enteropancreatic neurons

Meyer Leah , Roberts Anna , Liu Jieruo , Norton Mariana , Dunsterville Cecilia , Tao Yuxuan , Salem Victoria , G Murphy Kevin

Neurotensin is expressed throughout the gastrointestinal tract and acts as a gut hormone. Recent work has established neurotensin modulates lipid absorption at the gastrointestinal lumen, but its role in the control of glucose homeostasis remains unclear. Neurotensin acts via three receptors, including the NtsR1 and is endogenously released following the ingestion of olive oil. Previous work in our group has identified that neurotensin acutely improves glucose tolerance in bot...

Metabolite-dependent regulation of HCAR1 at a spatial level and its potential to influence local gut barrier integrity

Milner Annabelle , Brown Alastair , Frost Gary , Hanyaloglu Aylin

The Hydroxycarboxylic Acid Receptor 1 (HCAR1) is a Gαi/o-coupled GPCR known to be activated by both L- and D-lactate; metabolites produced by gut microbiota and anaerobic metabolism. Elevated D-lactate levels are indicative of dysbiosis and inflammatory bowel disease. As lactate can be transported into cells, it has the potential to activate HCAR1 at the plasma membrane and within intracellular locations resulting in diversified responses. Whether HCAR1 signalling is spat...

Female AKR1D1 knockout mice are protected against diet induced obesity and insulin resistance but not hepatic steatosis

Bailey Maira , Potter Tom , Larner Dean , Morgan Stuart , Lavery Gareth , Tomlinson Jeremy , Gathercole Laura

Bile acids and steroid hormones are potent regulators of metabolic phenotype. 5β-reductase (AKR1D1) is highly expressed in the liver where it catalyses a fundamental step in bile acid synthesis and inactivates steroid hormones. We have previously shown that male, but not female, AKR1D1 knockout (KO) mice on a normal chow diet are leaner than wildtype littermates but are not protected against diet induced obesity. Here we investigate the impact of a high fat diet on female...

Differential DNA methylation during postnatal development establishes a subpopulation of pancreatic beta cells with expression of the insulin secretion-enhancing gene, neuronatin

Yu Vanessa , Yong Fiona , Marta Angellica , Khadayate Sanjay , Bhattach Supriyo , Chen Keran , Georgiadou Eleni , Parveen Nazia , Marselli Lorella , De Luca Carmela , Suleiman Mara , Whilding Chad , Marchetti Piero , Dhawan Sangeeta , Withers Dominic , Rutter Guy , Millership Steven

Subpopulations of beta cells dictate overall ‘pacing’ of insulin secretion across the islet and therefore the control of glycaemia. Functional beta cell subpopulations also exist in human islets and have an altered subtype distribution in type 2 diabetes. However, the molecular control of the establishment and maintenance of beta cell hierarchy is poorly understood. We hypothesised that the epigenome would govern this heterogeneity. We have identified a novel subpopu...

The effect of snack foods containing rare sugars on glycaemic response, gut hormones and satiety in healthy UK adults

Smith Alison , Avery Amanda , Ford Rebecca , Goux Aurelie , Mukherjee Neil , Yang Qian , Jethwa Preeti

Dietary guidelines in the UK and worldwide recommend reducing the quantity of free sugars in the diet. The consumption of foods high in free sugars can lead to postprandial hyperglycaemia and hyperinsulinemia, which have been implicated in the development of metabolic diseases including type 2 diabetes and obesity. Rare sugars (naturally occurring monosaccharides which hardly exist in nature) have been found to suppress the postprandial elevation in blood glucose and improve g...

Investigating the pancreas-projecting enteric neurons in the regulation of metabolic homeostasis

Liu Jieruo , Meyer Leah , Chung Pei-En , Tao Yuxuan , Owen Bryn , Murphy Kevin

The regulation of insulin and glucagon secretion has traditionally been attributed to the gut-brain axis and direct sensing of blood glucose levels by pancreatic islets. However, the enteric nervous system may directly modulate pancreatic hormone release. This study focuses on a specific population of enteric neurons that exhibit the capability to transmit signals from the gut to the pancreas, potentially revealing new pathways of metabolic regulation. The gastrointestinal tra...

Investigating the role of CaSR in mediating effect on glucose tolerance via α-cell and β-cell signalling

Chung Pei-En , Zhang Jiabai , Norton Mariana , Meyer Leah , Dunsterville Cecilia , Liu Jieruo , Gribble Fiona , Reimann Frank , Chang Wehan , Murphy Kevin

High protein diets are hypothesised to improve glucose tolerance by modulating the secretion of gastroenteropancreatic hormones via amino-acid sensing. Glucagon, traditionally associated with hyperglycaemia, has beneficial effects on glucose homeostasis, potentially due to its role as an insulin secretagogue via intra-islet signalling and as a regulator of pulsatile insulin secretion. The calcium sensing receptor (CaSR), known for its role in calcium homeostasis, also function...

Case report - success story of GLP-1 agonist (liraglutide) treatment in someone with type 1 diabetes: A life transformed

Heald Adrian , Whyte Martin , Warner-Levy John , Belston Lleyton , Horne LInda , Gibson Martin

Introduction: Glucagon-like peptide-1(GLP-1) agonists are widely used for treatment of type 2 diabetes(T2D). To date a number of reports have described improvements in glucose control with the addition of a GLP-1 agonist to the insulin regime in treatment of type 1 diabetes(T1D). From a physiological perspective there is credence to the notion that a GLP-1 agonist will lower glucose levels in people with T1D as they do in T2D. GLP-1 is an endogenous hormone th...

An unexpected food-aversion in mice lacking functional leptin signalling

Curtis Anna , Jayal Yashoda , Zhou Zijing , Akalestou Elina , S Dhillo Waljit , G Murphy Kevin , M Owen Bryn

Defending body weight is a fundamental homeostatic process. Indeed, countless studies have demonstrated weight-maintaining hyperphagia in response to either increased energy expenditure or a reduction in the caloric density of available food. The principal effector of this adaptive food intake is thought to be the adipose tissue-derived hormone, leptin. According to the classical ’adipostat’ model, the hypoleptinemia resulting from weight loss drives food intake to r...

Rehman Khan Abdul , Javeed Ali , Adiat Mojeed , Akbar Shahzad , Pawlak Tadeusz

Glucose is the primary source of energy for cells and its levels are tightly regulated by the hormone insulin. In people with diabetes, the body either doesn’t produce enough insulin or doesn’t respond to insulin properly. Hyperglycemia can occur which carries high morbidity and mortality. Some common signs and symptoms include polyuria, polydipsia, polyphagia and fatigue. Diabetic ketoacidosis and hyperosmolar hyperglycaemic state are serious medical emergencies ass...

Metabolic phenotyping of the polygenic mouse model (NONcNZO10/LtJ) of type 2 diabetes to mimic the process of diabetes development and remission in human

Ojeda Laura , Onishi Ami , Junior Jair , Von Kriegsheim Alex , Morton Nicholas , Al-Mrabeh Ahmad

Background and Aims: Obesity is a major risk factor for type 2 diabetes (T2D). Remission of diabetes can be achieved by dietary weight loss although the underlying molecular mechanism(s) are unknown. These beneficial effects could be related to decreasing hepatic fat delivery to the pancreas and eventually restoring β-cell function. We hypothesised that hepatic de novo lipogenesis (DNL) is the primary driver of pancreas “lipotoxicity” and the pr...
