Cyclic AMP signalling in pancreatic islets
, 2010 Cyclic 3'5'AMP (cAMP) is an important physiological amplifier of glucose-induced insulin secretion by the pancreatic islet β-cell, where it is formed by the activity of adenylyl cyclases, which are stimulated by glucose, through elevation in ...

From Hyper- to Hypoinsulinemia and Diabetes: Effect of KCNH6 on Insulin Secretion
Cell Reports, 2018 Summary: Glucose-stimulated insulin secretion from islet β cells is mediated by KATP channels. However, the role of non-KATP K+ channels in insulin secretion is largely unknown. Here, we show that a non-KATP K+ channel, KCNH6, plays a key role in insulin

Insulin Secretion in Malignant Hyperpyrexia [PDF]
BMJ, 1974 An increased glucose-induced insulin response has been observed in patients susceptible to malignant hyperpyrexia. This raises the possibility that the membrane abnormality present in the calcium-storing membranes in the muscle cell in malignant hyperpyrexia may be present also in the beta cell of the pancreas.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

, 2007 The present study was undertaken to determine the main metabolic secretory signals generated by the mitochondrial substrate MeS (methyl succinate) compared with glucose in mouse and rat islets and to understand the differences.

Effect of the dietary fat quality on insulin sensitivity. [PDF]
, 2008 Recent evidence shows that specific fatty acids affect cell metabolism, modifying the balance between fatty acid oxidation and lipogenesis. These effects may have important implications in addressing the present epidemic of nutrition-related chronic ...

Nature CommunicationsThe insulin receptor entrains tissue growth and metabolism to nutritional conditions. Complete loss of function in humans leads to extreme insulin resistance and infantile mortality, while loss of 80-90% function permits longevity of decades.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Oscillatory glucose flux in INS 1 pancreatic beta cells: A self-referencing microbiosensor study
, 2011 Signaling and insulin secretion in beta cells have been reported to demonstrate oscillatory modes, with abnormal oscillations associated with type 2 diabetes.

Aldosterone status associates with insulin resistance in patients with heart failure-data from the ALOFT study [PDF]
, 2009 <b>Background</b>: Aldosterone plays a key role in the pathophysiology of heart failure. In around 50% of such patients, aldosterone 'escapes' from inhibition by drugs that interrupt the renin-angiotensin axis; such patients have a worse ...
