Disruption of the WFS1 gene in mice causes progressive beta-cell loss and impaired stimulus-secretion coupling in insulin secretion.
Wolfram syndrome, an autosomal recessive disorder characterized by juvenile-onset diabetes mellitus and optic atrophy, is caused by mutations in the WFS1 gene. In order to gain insight into theExpand

ATF4-mediated induction of 4E-BP1 contributes to pancreatic beta cell survival under endoplasmic reticulum stress.
Endoplasmic reticulum (ER) stress-mediated apoptosis may play a crucial role in loss of pancreatic beta cell mass, contributing to the development of diabetes. Here we show that induction of 4E-BP1,Expand

WFS1-deficiency increases endoplasmic reticulum stress, impairs cell cycle progression and triggers the apoptotic pathway specifically in pancreatic beta-cells.
Wolfram syndrome, an autosomal recessive disorder associated with diabetes mellitus and optic atrophy, is caused by mutations in the WFS1 gene encoding an endoplasmic reticulum (ER) membrane protein.Expand

WFS1 protein modulates the free Ca2+ concentration in the endoplasmic reticulum
The WFS1 gene, encoding an endoplasmic reticulum (ER) membrane glycoprotein, is mutated in Wolfram syndrome characterized by diabetes mellitus and optic atrophy. Herein, Ca2+ dynamics were examinedExpand

Direct Correlation Between Ischemic Injury and Extracellular Glycine Concentration in Mice With Genetically Altered Activities of the Glycine Cleavage Multienzyme System
Background and Purpose— Ischemia elicits the rapid release of various amino acid neurotransmitters. A glutamate surge activates N-methyl-d-aspartate (NMDA) glutamate receptors, triggering deleteriousExpand

Efficient and controlled gene expression in mouse pancreatic islets by arterial delivery of tetracycline-inducible adenoviral vectors.
Gene transfer with adenovirus vectors has been used extensively for pancreatic islet research. However, infection efficiency varies among reports. We reevaluated the infection efficiency, definedExpand

The JNK pathway modulates expression and phosphorylation of 4E‐BP1 in MIN6 pancreatic β‐cells under oxidative stress conditions
Stress‐mediated apoptosis may play a crucial role in loss of pancreatic β‐cell mass, contributing to the development of diabetes. We have recently identified that translational control involving theExpand

Addition of sitagliptin or metformin to insulin monotherapy improves blood glucose control via different effects on insulin and glucagon secretion in hyperglycemic Japanese patients with type 2
This study aimed to explore the effects of the dipeptidyl peptidase-4 inhibitor sitagliptin and the biguanide metformin on the secretion of insulin and glucagon, as well as incretin levels, inExpand
