Annexin 1 interaction with calpain: a role in apoptosis

Peng Zhou , Morris John , Christian Helen

Annexin 1 (ANXA1) is a 37 Kd member of the annexin family of Ca2+− and phospholipid binding proteins that has been well demonstrated to act as a mediator of glucocorticoid action in inflammation and in the control of anterior pituitary hormone release. ANXA1 is also proapoptotic and has been identified as a mediator of apoptotic cell engulfment (Solito et al. 2003 FASEB J 17:1544; Arur et al. 2003 Dev Cell 4:587). Using yeast two hybrid screening...

Investigating the role of abca1 in the externalisation of annexin 1 in the anterior pituitary

Omer S , Christian HC , Morris JF

Annexin 1 (Anx-1), a 37kDa protein, is a member of the super-family of Ca 2+ and phospholipid-binding annexin proteins and acts as a mediator of glucocorticoid (GC) action in the host defense and neuroendocrine systems. In the anterior pituitary Anx-1 is expressed mainly by folliculostellate (FS) cells and mediates the early delayed feedback inhibition exerted by GCs on the release of ACTH and other pituitary hormones. It has been previously demonstrated that TtT/GF...

miR-10b as a novel negative regulator of brown adipogenesis

Kalenderoglou Nikoletta , Younis Awais , Christian Mark

Improved knowledge of adipogenesis is necessary to gain insight into brown and white fat physiology. Interest in adipocyte differentiation has increased markedly over the past few years with emphasis on intersection between microRNAs (miRNAs) and the transcriptional cascade that controls adipogenesis and metabolic dysfunction. The aim of this study is to identify miRNAs that regulate white and brown adipocyte differentiation and define miRNA action in a stem cell model of adip...

Frequency and causes of hypophosphatemia in internal medicine patients

Hubener Lisa , Haas Christian , Harbeck Birgit

Background: Hypophosphatemia is of relevant clinical importance, especially in its severe form. Hypophosphatemia occurs when serum phosphate levels are below 0.84 mmol/l. It can be divided into a mild form (serum phosphate between 0.5 and 0.83 mmol/l), a moderate form (serum phosphate between 0.3 and 0.5 mmol/l) and a severe form (serum phosphate <0.3 mmol/l). Approximately 2.2 to 3.1% of hospitalized patients not requiring intensive care are affected (Brunelli et al., 200...

Lipopolysaccharide signalling modulates brown fat transcriptome and cytokine secretion

Omran Farah , Murphy Alice , McTernan Philip , Christian Mar

Background: Brown adipose tissue (BAT) thermogenesis offers an appealing prospect to combat obesity. Obesity is characterised by a state of chronic inflammation in adipose tissue mediated by the secretion of a range of inflammatory-cytokines. Our previous work has highlighted that a gut-derived inflammatory agent, lipopolysaccharide (LPS), reduces brown adipocyte activity, insulin sensitivity and mitochondrial-function and is increased with obesity and type 2 diabetes mellitus...

Audit of South Wales Neuroendocrine MDT pathology reports

Peaker James , Morgan Meleri , Rees Aled , Khan Mohid , Christian Adam

The South Wales regional NET Multidisciplinary Meeting (MDT) discusses patients on a monthly basis. The European Neuroendocrine Tumour Society (ENETS) have guidance on expected pathology input into a NET MDT service. We assessed pathology reports submitted and discussed in 2016 for compliance with ENETS criteria, and determined the time from pathology reporting to MDT discussion. 117 patients had pathology submitted for review in 2016 and were assessed by one specialist NET pa...

Grading systems in gastroenteropancreatic neuroendocrine tumours

Hobby Charlotte , Morgan Meleri , Rees Aled , Khan Mohid , Christian Adam

Objective: To compare 3 methods of generating Ki-67% in gastroenteropancreatic neuroendocrine tumours (GEP-NETs).Methods: Twenty-four slides were used to generate 49 images for analysis. Each image was analysed and 3 different methods were used to calculate Ki-67%.Results: The comparison of Ki-67% from counting and estimating using the diameter (shortcut method) was strongly positively correlated, whereas the Ki-67% from counting a...

Disorganised anterior pituitary ultrastructure in choriogonadotrophin-alpha (Cga) null female mice

Davies Jessica , Gergics Peter , Camper Sally , Christian Helen

Choriogonadotrophin-alpha (Cga) is one of the first molecular markers for the developing pituitary gland previously known as ‘alpha-subunit’, common to thyroid-stimulating hormone (TSH), luteinising hormone (LH) and follicle-stimulating hormone (FSH). Mice lacking Cga are hypogonadal and exhibit profound hypothyroidism and dwarfism. Light microscopy of Cga null mice has shown that pituitary thyrotrophs...

Metabolic Endotoxemia impacts mitochondrial function and adipocyte browning in a depot specific manner in Human abdominal adipose tissue

Murphy Alice , Omran Farah , Piya Milan , Christian Mark , McTernan Philip

Introduction: Central obesity is a significant risk factor for type 2 diabetes mellitus (T2DM), with omental adipose tissue (AT) particularly involved in such risk. Additionally, obesity can cause low-level gut-derived endotoxemia, which may drive metabolic dysfunction in AT through mitochondrial damage and reduced BRITE (brown-in-white) adipocytes. Bariatric surgery reduces obesity and may prevent such dysfunction. This study investigated whether endotoxin: 1) impairs mitocho...
