    TOP STORY 

    Researchers Uncover Potential ‘Cure’ for Type 1 Diabetes  ShareThis
    Type 1 diabetes could be converted to an asymptomatic, non-insulin-dependent disorder by eliminating the actions of a specific hormone, new findings suggest. These findings in mice show that insulin becomes completely superfluous and its absence does not cause diabetes or any other abnormality when the actions of glucagon are suppressed.

    SCIENCE NEWS

    Artificial Pancreas in Pregnancy Promises Fewer Diabetes Deaths
    Research has for the first time successfully demonstrated the potential of an artificial pancreas in pregnant women with type 1 diabetes. [Press release from the University of Cambridge discussing online prepublication in Diabetes Care]

    Immunomedics Reports First Experimental Studies Combining Antibody-Drug Conjugate with Antibody-Directed Radiation Therapy for Pancreatic Cancer
    Immunomedics, Inc. announced that combining antibody-directed drug and radionuclide therapeutics for pancreatic cancer improved efficacy in preclinical studies with minimal toxicity. [Press release from Immunomedics, Inc. discussing research presented at the American Society of Clinical Oncology 2011 Gastrointestinal Cancers Symposium]

    DIABETES

    Magnetosome-Like Ferrimagnetic Iron Oxide Nanocubes for Highly Sensitive MRI of Single Cells and Transplanted Pancreatic Islets
    Pancreatic islet grafts and their rejection could be imaged using ferrimagnetic iron oxide nanocubes (FIONs) on a 1.5 T clinical magnetic resonance imaging (MRI) scanner. The strong contrast effect of FIONs enabled MR imaging of transplanted islets in small rodents as well as in large animals. [ Proc Natl Acad Sci U S A]

    Glucagon Receptor Knockout Prevents Insulin-Deficient Type 1 Diabetes in Mice
    Researchers conclude that blocking glucagon action prevents the deadly metabolic and clinical derangements of type 1 diabetic mice. [Diabetes]

    Ongoing Beta Cell Turnover in Adult Nonhuman Primates Is Not Adaptively Increased in Streptozotocin-Induced Diabetes
    Researchers aimed 1) to measure beta cell turnover in adult nonhuman primates; 2) to establish the relative contribution of beta cell replication and formation of new beta cells from other precursors; and 3) to establish whether there is an adaptive increase in beta cell formation in streptozotocin-induced diabetes in adult nonhuman primates. [Diabetes]

    The Expression and Function of Glucose-Dependent Insulinotropic Polypeptide in the Embryonic Mouse Pancreas
    Glucose-dependent insulinotropic polypeptide signaling may play a role in early embryonic pancreas differentiation to form insulin-positive cells or beta cells. [Diabetes]

    Phosphatidylinositol-4-Phosphate-5-Kinase Alpha Deficiency Alters Dynamics of Glucose-Stimulated Insulin Release to Improve Glucohomeostasis and Decrease Obesity in Mice
    Findings suggest that phosphatidylinositol-4-phosphate-5-kinase alpha plays a complex role in restricting insulin release from pancreatic beta cells through helping to maintain plasma membrane phosphatidylinositol-4,5-bisphosphate levels and integrity of the actin cytoskeleton under both basal and stimulatory conditions. [Diabetes]

    Stage-Specific Signaling Through TGF Beta Family Members and WNT Regulates Patterning and Pancreatic Specification of Human Pluripotent Stem Cells
    Researchers elucidated the temporal requirements for TGF beta family members and canonical WNT signaling at these developmental stages and show that the duration of nodal/activin A signaling plays a pivotal role in establishing an appropriate definitive endoderm population for specification to the pancreatic lineage. [Development]

    Sox9+ Ductal Cells Are Multipotent Progenitors Throughout Development But Do Not Produce New Endocrine Cells in the Normal or Injured Adult Pancreas
    Although endocrine cells arise from the Sox9+ ductal domain throughout embryogenesis and the early postnatal period, Sox9+ ductal cells of the adult pancreas no longer give rise to endocrine cells under both normal conditions and in response to partial duct ligation. [ Development]

    Closed-Loop Insulin Delivery During Pregnancy Complicated by Type 1 Diabetes
    This study evaluated closed-loop insulin delivery with a model predictive control algorithm during early (12-16 weeks) and late gestation (28-32 weeks) in pregnant women with type 1 diabetes. [Diabetes Care]

    Co-Transplantation of Mesenchymal Stem Cells Maintains Islet Organization and Morphology in Mice
    Co-transplantation of islets with mesenchymal stem cells (MSCs) had a profound impact on the remodeling process, maintaining islet organization and improving islet revascularization. MSCs also improved the capacity of islets to reverse hyperglycemia. [Diabetologia]

    PANCREATIC CANCER

    Spatial Regulation of RhoA Activity During Pancreatic Cancer Cell Invasion Driven by Mutant p53
    Researchers demonstrate for the first time, an analysis of RhoA activity at a subcellular level using FLIM-FRET (fluorescence lifetime imaging microscopy-fluorescence resonance energy transfer) imaging in a live animal model of pancreatic cancer. [Cancer Res]

    Intracellular CD24 Inhibits Cell Invasion by Posttranscriptional Regulation of BART Through Interaction with G3BP
    Researchers report a novel function for the CD24 molecule in pancreatic cancer cells. Results imply that surface CD24 may play a role in the inhibition of cell invasion and metastasis, and that intracellular CD24 inhibits invasiveness and metastasis through its influence on the posttranscriptional regulation of Binder of Arl Two (BART) mRNA levels via G3BP RNase activity. [Cancer Res]

    Combined Blockade of Src Kinase and Epidermal Growth Factor Receptor with Gemcitabine Overcomes STAT3-Mediated Resistance of Inhibition of Pancreatic Tumor Growth
    Results provide evidence that combined targeted biological therapy in addition to cytotoxic chemotherapy can overcome treatment resistance. Such treatment strategies may be used to tailor therapy based on identified biomarkers of resistance to targeted monotherapy. [Clin Cancer Res]

    INDUSTRY NEWS

    Six Million Euros for Europe Wide Diabetes Research Network
    The Peninsula College of Medicine and Dentistry, University of Exeter, is one of 13 academic institutions and businesses across Europe to form a EUR 6 million research and analysis network, funded by the EU for a five-year period, which is designed to investigate the possible role of virus infection in the cause of type 1 diabetes. [Peninsula College of Medicine and Dentistry Press Release]

    Diamyd Expects to Begin Reporting Phase III Results in Late Spring 2011
    Diamyd Medical’s President and CEO Elisabeth Lindner states in the CEO comments in a quarterly report that the Company expects to begin reporting the results from the European Phase III trial in type 1 diabetes as planned in late spring 2011. [Diamyd Medical AB Press Release]

    Ecron Acunova Adds on Stem Cell Therapy and Diabetes Center to Conduct Studies for Global and Indian Sponsors
    Ecron Acunova, a full-fledged clinical research organization, has added an additional focus area which is the stem cell therapy and diabetes centre. The center provides the marketing authorization for allogenic or autologous stem cell products. [PharmaBiz]

    Number of Americans with Diabetes Rises to Nearly 26 Million
    Nearly 26 million Americans have diabetes, according to new estimates from the Centers for Disease Control and Prevention. In addition, an estimated 79 million U.S. adults have prediabetes, a condition in which blood sugar levels are higher than normal, but not high enough to be diagnosed as diabetes. [Centers for Disease Control and Prevention Press Release]

    American Diabetes Association Announces 2010 Diabetes Year-in-Review
    The American Diabetes Association released its diabetes year-in-review for 2010. The complete list, which highlights focusing on diabetes achievements by the numbers, can be found at www.diabetes.org. [American Diabetes Association Press Release]
