SLC25A46 promotes mitochondrial fission and mediates resistance to lipotoxic stress in INS-1E insulin-secreting cells

Glucose sensing in pancreatic D-cells depends on oxidative phosphorylation and mitochondria-derived signals that promote insulin secretion. Using mass spectrometry-based phosphoproteo-mics to search for downstream effectors of glucose-dependent signal tran ...

Porphyrin metalla-assemblies coupled to cellulose nanocrystals for PDT and imaging applications

Georges Wagnières

Photodynamic therapy (PDT) is an interesting and promising approach to tackle a broad spectrum of cancer. With the combination of a photosensitizer, light and oxygen, PDT achieves a unique selectivity by the production of localized reactive oxygen species ...

Type 2 diabetes disrupts circadian orchestration of lipid metabolism and membrane fluidity in human pancreatic islets

Jonathan Paz Montoya, Howard Riezman

Recent evidence suggests that circadian clocks ensure temporal orchestration of lipid homeostasis and play a role in pathophysiology of metabolic diseases in humans, including type 2 diabetes (T2D). Nevertheless, circadian regulation of lipid metabolism in ...

Islet Encapsulation: New Developments for the Treatment of Type 1 Diabetes

Sandrine Gerber, Qixing Zhang, Yi Wang, Léo Bühler

Islet transplantation is a promising approach for the treatment of type 1 diabetes (T1D). Currently, clinical islet transplantation is limited by allo - and autoimmunity that may cause partial or complete loss of islet function within a short period of tim ...

Pancreatic Sirtuin 3 Deficiency Promotes Hepatic Steatosis by Enhancing 5-Hydroxytryptamine Synthesis in Mice With Diet-Induced Obesity

Johan Auwerx, Kristina Schoonjans

Sirtuin 3 (SIRT3) is a protein deacetylase regulating beta-cell function through inhibiting oxidative stress in obese and diabetic mice, but the detailed mechanism and potential effect of beta-cell-specific SIRT3 on metabolic homeostasis, and its potential ...

Multipotent mesenchymal stromal cells derived from porcine exocrine pancreas improve insulin secretion from juvenile porcine islet cell clusters.

Sandrine Gerber, Luca Szabó, Léo Bühler

Neonatal and juvenile porcine islet cell clusters (ICC) present an unlimited source for islet xenotransplantation to treat type 1 diabetes patients. We isolated ICC from pancreata of 14 days old juvenile piglets and characterized their maturation by immuno ...

Cancer Cells Retrace a Stepwise Differentiation Program during Malignant Progression

Douglas Hanahan, Krisztian Homicsko, Mohammad Sadegh Saghafinia, Stephan Wullschleger, Iacovos Michael, Giovanni Ciriello

Pancreatic neuroendocrine tumors (PanNET) comprise two molecular subtypes, relatively benign islet tumors (IT) and invasive, metastasis-like primary (MLP) tumors. Until now, the origin of aggressive MLP tumors has been obscure. Herein, using multi-omics ap ...

Augmented mitochondrial energy metabolism is an early response to chronic glucose stress in human pancreatic beta cells

Loïc Dayon, Andreas Wiederkehr, Sofia Moco, Isabelle Chareyron

Aims/hypothesis In islets from individuals with type 2 diabetes and in islets exposed to chronic elevated glucose, mitochondrial energy metabolism is impaired. Here, we studied early metabolic changes and mitochondrial adaptations in human beta cells durin ...
