Microtubule-mediated GLUT4 trafficking is disrupted in insulin-resistant skeletal muscle

Martinus Gijs, Raphaël Etienne Jean Trouillon, Martin Rainer Wohlwend

Microtubules serve as tracks for long-range intracellular trafficking of glucose transporter 4 (GLUT4), but the role of this process in skeletal muscle and insulin resistance is unclear. Here, we used fixed and live-cell imaging to study microtubule-based ...

The role of nicotinamide riboside metabolism in pancreatic beta cells

Angélique Satoko Cercillieux

Pancreatic beta cells play a major role in the regulation of glucose homeostasis by secreting insulin in response to elevated blood glucose levels. A gradual deterioration of functional beta cell mass and the chronic elevation of blood glucose levels are c ...

Magnitude of gluconeogenesis and endogenous glucose production: are they predictable in clinical settings?

Marc Anthony David Habisreutinger

Introduction: Regulation of endogenous glucose production (EGP) is essential for glucose homeostasis. It includes gluconeogenesis (GNG) from non-carbohydrate substrates and hepatic glycogenolysis. Both these pathways are dysregulated in acute stress, but t ...

Co-regulation of endothelial and myogenic cell fates through intercellular crosstalk in skeletal muscle

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...
