TOP STORY
Scientists Discover Link Between Inflammation and Pancreatic Cancer
Solving part of a medical mystery, researchers have established a link between molecules found in an inflamed pancreas and the early formation of pancreatic cancer. [Press release from the University of California, San Francisco discussing online prepublication in Cancer Cell]

SCIENCE NEWS

Scientists Identify Key Trigger for Pancreatic Beta Cell Regeneration
Researchers have identified a key signal that prompts existing insulin-producing beta cells in the pancreas to form new beta cells in mice, a breakthrough discovery that may ultimately help researchers find ways to restore or increase beta cell function in people with type 1 diabetes. [Press release from the Juvenile Diabetes Research Foundation International discussing online prepublication in Cell Metabolism]

Findings May Help Keep Pancreatic Disease Off the Menu
Results showed that there is a refined mechanism that the pancreas switches on to avoid the progression of acute pancreatitis to a lethal condition. [Press release from EurekAlert! discussing research presented at Experimental Biology 2011]

Preclinical Studies in Pancreatic Cancer and Melanoma Demonstrated ADI-PEG 20 Works Synergistically with Inhibitors of Autophagy
Polaris Group announced that data from preclinical studies of ADI-PEG 20, the Company’s pegylated arginine deiminase therapeutic, is synergistic with hydroxychloroquine in a human pancreatic cancer cell line and with tumor necrosis factor-related apoptosis-inducing ligand in human melanoma cell lines. [Press release from PR Newswire discussing research presented at the 102nd Annual Meeting of the American Association for Cancer Research]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

DIABETES

Control of Pancreatic β Cell Regeneration by Glucose Metabolism
Using islet transplantation experiments, researchers show that β cell mass is controlled systemically rather than by local factors such as tissue damage. [Cell Metab]

Permanent Protection of PLG Scaffold Transplanted Allogeneic Islet Grafts in Diabetic Mice Treated with ECDI-Fixed Donor Splenocyte Infusions
This study examined this technology in allogeneic islet transplantation and determined whether transplant tolerance could be effectively induced to protect PLG scaffold transplanted allogeneic islets. [Biomaterials]

Immobilization of Soluble Complement Receptor 1 on Islets
Human soluble complement receptor 1 was immobilized on the pancreatic islet of Langerhans cell surface through poly(ethylene glycol)-conjugated phospholipid without loss of islet cell viability or insulin secretion ability. [Biomaterials]

Differential Regulation of Adaptive and Apoptotic Unfolded Protein Response Signaling by Cytokine-Induced Nitric Oxide Production in Mouse Pancreatic Beta Cells
Researchers tested the role of nitric oxide in cytokine-induced endoplasmic reticulum (ER) stress and the subsequent unfolded protein response in beta cells. [Diabetologia]

Elutriated Stem Cells Derived from the Adult Bone Marrow Differentiate into Insulin Producing Cells In Vivo and Reverse Chemical Diabetes
Researchers examined the possibility that adult bone marrow cells participate in recovery from chemical diabetes through neogenesis of insulin producing cells. [Stem Cells Dev]

Visfatin Inhibits Apoptosis of Pancreatic β-Cell Line, MIN6, via the Mitogen-Activated Protein Kinase/Phosphoinositide 3-Kinase Pathway
This study investigated the protective effects of visfatin on palmitate-induced islet β cell apoptosis in the clonal mouse pancreatic β cell line MIN6. [J Mol Endocrinol]

PANCREATIC CANCER

Stat3 and MMP7 Contribute to Pancreatic Ductal Adenocarcinoma Initiation and Progression
Using a Kras-driven mouse model of pancreatic ductal adenocarcinoma (PDA), researchers establish that the inflammatory mediator Stat3 is a critical component of spontaneous and pancreatitis-accelerated PDA precursor formation and supports cell proliferation, metaplasia-associated inflammation, and MMP7 expression during neoplastic development. [Cancer Cell]

Endogenous Myc Maintains the Tumor Microenvironment
Researchers show that inhibition of endogenous Myc also triggers ubiquitous regression of tumors in a simian virus 40-driven pancreatic islet tumor model. [Genes Dev]

Intracellular Activation of Trypsinogen in Transgenic Mice Induces Acute But Not Chronic Pancreatitis
Intra-acinar activation of trypsinogen is sufficient to initiate acute pancreatitis. However, the primary response to intracellular trypsin activity is rapid induction of acinar cell death via apoptosis which facilitates resolution of the acute inflammation rather than causing chronic pancreatitis. [Gut]

Type I Interferons as Radiosensitisers for Pancreatic Cancer
Type I interferons have radiosensitising effects in pancreatic cancer cell lines. This radiosensitising property might lead to an improved response to treatment in pancreatic cancer. [Eur J Cancer]

POLICY NEWS
U.S. Panel Backs Novartis’ Pancreatic Cancer Drug
Novartis AG’s cancer drug, Afinitor, showed safety and efficacy in treating a rare type of pancreatic cancer that has few treatment options, a U.S. advisory panel said. [Food and Drug Administration, United States]

Pfizer Drug Wins FDA Panel’s Backing for Pancreatic Cancer
Pfizer Inc. won a U.S. panel’s backing to expand marketing of a cancer drug for patients with a rare type of pancreatic tumor.
