TL;DR: The MIN6 cell line will be especially useful to analyze the molecular mechanisms by which beta cells regulate insulin secretion in response to extracellular glucose concentrations, and a possible role of GT isoforms in glucose sensing by beta cells is discussed.

TL;DR: The JDS extensively evaluated the usefulness and feasibility of more extended use of HbA1c in the diagnosis of diabetes based on Japanese epidemiological data, and then the ‘Report of the Committee on the Classification and Diagnostic Criteria of Diabetes Mellitus’ was published in the Journal of Diabetes Investigation5 and Diabetology International.

TL;DR: The data implicate KCNQ1 as a diabetes susceptibility gene in groups of different ancestries as well as in two independent Japanese populations, and the risk allele of this polymorphism was associated with impairment of insulin secretion according to the homeostasis model assessment of β-cell function or the corrected insulin response.

TL;DR: In this paper, the authors localized the Wolfram syndrome (WFS) gene to a BAC/P1 contig of less than 250 kb and found that mutations in a novel gene encoding a putative transmembrane protein were associated with the disease phenotype.

TL;DR: Glucose-stimulated insulin secretion, glucose transport, glucose phosphorylation and glucose utilization have been characterized in the insulinoma cell line MIN6, indicating that this cell line is an appropriate model for studying the mechanism of glucose- stimulated insulin secretion in pancreatic beta cells.
