TOP STORY
Interleukin-6 Enhances Insulin Secretion by Increasing Glucagon-Like Peptide-1 Secretion from L Cells and Alpha Cells
Researchers show that administration of interleukin-6 (IL-6) or elevated IL-6 concentrations in response to exercise stimulate glucagon-like peptide-1 secretion from intestinal L cells and pancreatic alpha cells, improving insulin secretion and glycemia. [Nat Med] Abstract

DIABETES

Synergistic Reversal of Type 1 Diabetes in NOD Mice with Anti-CD3 and Interleukin-1 Blockade Evidence of Improved Immune Regulation
Researchers postulated that blockade of interleukin-1ß would modulate the effects of anti-CD3 monoclonal antibody in treating diabetes in NOD mice. [Diabetes] Abstract

Susceptibility of Glucokinase-MODY Mutants to Inactivation by Oxidative Stress in Pancreatic β-Cells
Investigators tested the hypothesis that glucokinase (GK) mutants that cause maturity onset diabetes of the young (GK-MODY) show compromised activity and posttranslational regulation in β-cells. [Diabetes] Abstract

Immunohistochemical Characterization of Cells Co-Producing Insulin and Glucagon in the Developing Human Pancreas
Researchers sought to characterize the transcription factor profile of cells that co-produce insulin and glucagon in the developing human pancreas, and thus to gain insight into their potential fate during normal pancreas development. [Diabetologia] Abstract

Temporal Restriction of Pancreatic Branching Competence During Embryogenesis Is Mirrored in Differentiating Embryonic Stem Cells
In order to develop methods for the generation of insulin-producing β-cells for the treatment of diabetes, investigators have used GFP-tagged ESCs to elucidate the process of pancreas development. [Stem Cells Dev] Abstract

Ectopic PDX-1 Expression Directly Reprograms Human Keratinocytes Along Pancreatic Insulin-Producing Cells Fate
Scientists ectopically expressed non-integrating pancreatic differentiation factors in ectoderm-derived human keratinocytes to determine whether these factors could directly induce endoderm-derived pancreatic lineage and β-cell-like function. [PLoS One] Abstract

PANCREATIC CANCER

Characterization of dsRNA-Induced Pancreatitis Model Reveals the Regulatory Role of IFN Regulatory Factor 2 (Irf2) in Trypsinogen5 Gene Transcription

Researchers speculate that Trypsin5, the trypsinogen5 gene product, leaking from dead acinar cells triggers a chain reaction leading to lethal pancreatitis in mice deficient for interferon regulatory factor 2 (Irf2-/- mice) because it is resistant to a major endogenous trypsin inhibitor, Spink3. [Proc Natl Acad Sci USA]
Abstract

Copy Number Variation at 6q13 Functions as a Long-Range Regulator and Is Associated with Pancreatic Cancer Risk
The study examined the functional significance of CNVR2966.1 at 6q13 and its association with pancreatic cancer susceptibility. [Carcinogenesis] Abstract

MUC13 Mucin Augments Pancreatic Tumorigenesis
Scientists have investigated the expression profile and functions of MUC13 in pancreatic cancer progression. [Mol Cancer Ther] Abstract

Stem-Like and Non-Stem Human Pancreatic Cancer Cells Distinguished by Morphology and Metastatic Behavior
Researchers report here that XPA1 human pancreatic cancer cells are dimorphic. [J Cell Biochem] Abstract

OGX-427 Inhibits Tumor Progression and Enhances Gemcitabine Chemotherapy in Pancreatic Cancer
In this study, researchers demonstrate using tissue microarrays of 181 patients that heat shock protein 27 expression and phosphorylation levels increase in moderately differentiated tumors to become uniformly highly expressed in metastatic samples. [Cell Death Dis] Abstract | Press Release
