TOP STORY

Discovery of Insulin Switches in Pancreas Could Lead to New Diabetes Drugs
Researchers have discovered how a hormone turns on a series of molecular switches inside the pancreas that increases production of insulin. [Press release from the Salk Institute for Biological Studies discussing online prepublication in the Proceedings of the National Academy of Sciences USA] Press Release | Abstract

PUBLICATIONS (Ranked by Impact Factor of the Journal)

DIABETES

Inhibition of Id1 Augments Insulin Secretion and Protects Against High-Fat Diet–Induced Glucose Intolerance
Here, researchers investigated the role of Id1 in insulin secretion and glucose homeostasis. [Diabetes] Abstract | Press Release

Specific Glucose-Induced Control of Insulin Receptor Substrate-2 Expression Is Mediated via Ca2+-Dependent Calcineurin/NFAT Signaling in Primary Pancreatic Islet β-Cells
The aim was to investigate the molecular mechanism on how glucose regulates insulin receptor substrate-2 gene expression in β-cells. [Diabetes] Abstract

FoxO Feedback Control of Basal IRS-2 Expression in Pancreatic β-Cells Is Distinct From That in Hepatocytes
The molecular mechanism for feedback control of insulin receptor substrate (IRS) signaling to decrease IRS-2 expression in liver and β-cells is quite distinct, with a predominant role played by FoxO3a in β-cells. [Diabetes] Abstract

Combining Antigen-Based Therapy with GABA Treatment Synergistically Prolongs Survival of Transplanted ß-Cells in Diabetic NOD Mice
Based on γ-aminobutyric acid’s (GABA) ability to inhibit different autoimmune diseases and its safety profile, researchers tested whether the combination of antigen-based therapy with GABA treatment could prolong the survival of transplanted ß-cells in newly diabetic nonobese diabetic (NOD) mice. [PLoS One] Abstract | Press Release

Pdx1 and Ngn3 Overexpression Enhances Pancreatic Differentiation of Mouse ES Cell-Derived Endoderm Population
In order to define the molecular mechanisms regulating the specification and differentiation of pancreatic β-islet cells, researchers investigated the effect of upregulating Pdx1 and Ngn3 during the differentiation of the β-islet-like cells from murine embryonic stem (ES) cell-derived activin induced-endoderm. [PLoS One] Abstract | Press Release

PANCREATIC CANCER

Nuclear Receptor Liver Receptor Homologue 1 (LRH-1) Regulates Pancreatic Cancer Cell Growth and Proliferation
In this work, investigators show that LRH-1 transcription is activated up to 30-fold in human pancreatic cancer cells compared to normal pancreatic ductal epithelium. [Proc Natl Acad Sci USA] Abstract

AGR2 Is a Novel Surface Antigen that Promotes the Dissemination of Pancreatic Cancer Cells through Regulation of Cathepsins B and D
Here, researchers investigated the role and mechanism of action of the metastasis-associated protein anterior gradient 2 (AGR2) in the pathogenesis of pancreatic cancer. [Cancer Res] Abstract

Combined Blockade of Integrin α4β1 Plus Cytokines SDF-1α or IL-1β Potently Inhibits Tumor Inflammation and Growth
Here investigators show how the chemoattractants SDF-1α and IL-1β collaborate with myeloid cell integrin α4β1 to promote tumor inflammation and growth. [Cancer Res] Abstract

A KrasG12D-Driven Genetic Mouse Model of Pancreatic Cancer Requires Glypican-1 for Efficient Proliferation and Angiogenesis
The data demonstrates in an oncogenic Kras-driven genetic mouse model of pancreatic ductal adenocarcinoma (PDAC) that tumor growth, angiogenesis and invasion are enhanced by glypican-1 (GPC1), and suggest that suppression of GPC1 may be an important component of therapeutic strategies in PDAC. [Oncogene] Abstract

Quality of Life in 265 Patients with Gastroenteropancreatic or Bronchial Neuroendocrine Tumors Treated with [177Lu-DOTA0,Tyr3]Octreotate
In this study, scientists investigated the quality of life and symptoms after [177Lu-DOTA0,Tyr3]octreotate therapy in patients with inoperable or metastasized gastroenteropancreatic or bronchial neuroendocrine tumors. [J Nucl Med] Abstract | Press Release
