SCIENCE NEWS Missing Molecules Hold Promise of Therapy for Pancreatic Cancer The production of a particular cluster of genetic snippets known as microRNAs is dramatically reduced in human pancreatic tumor cells compared to healthy tissue. When researchers restored this tiny regulator, called miR-143/145, back to normal levels in human pancreatic cancer cells, those cells lost their ability to form tumors.

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal) DIABETES Variants and Haplotypes of TCF7L2 Are Associated with Beta Cell Function in Patients with Newly Diagnosed Type 2 Diabetes: The Verona Newly Diagnosed Type 2 Diabetes Study (VNDS) 1 TCF7L2 diabetes risk variants, either as single-nucleotide polymorphisms or as haplotypes, detrimentally influence beta cell function and might play a role in determining the metabolic phenotype of patients with newly diagnosed type 2 diabetes. [J Clin Endocrinol Metab] Resveratrol Potentiates Glucose-Stimulated Insulin Secretion in INS-1E Beta Cells and Human Islets Through Sirt1 Dependent Mechanism Resveratrol markedly enhanced the glucose response of INS-1E cells and human islets, even after removal of the compound from the medium. [J Biol Chem] Structural Polymorphism of Human Islet Amyloid Polypeptide (hIAPP) Oligomers Highlights the Importance of Interfacial Residue Interactions In this work, on the basis of recent solid-state NMR and mass-per-length data, researchers model a series of human islet amyloid polypeptide oligomers with different beta-layers (one, two, and three layers), symmetries (symmetry and asymmetry), and associated interfaces using molecular dynamics simulations. [Biomacromolecules] Beta Cell Neogenesis: Experimental Considerations in Adult Stem Cell Differentiation Using the smallest subset of bone marrow cells lacking immuno-hematopoietic lineage markers, researchers have detected incorporation and conversion into insulin-producing cells. [Stem Cells Dev] Bone Marrow-Derived Mesenchymal Stem Cells Co-Cultured with Pancreatic Islets Display Beta Cell Plasticity The direct co-culturing effect of rat bone-marrow-derived mesenchymal stem cells on the pancreatic islets was studied to obtain functional islet cells. [J Tissue Eng Regen Med] PANCREATIC CANCER Repression of the miR-143/145 Cluster by Oncogenic Ras Initiates a Tumor-Promoting Feed-Forward Pathway Loss of miR-143/145 expression is observed frequently in KRAS mutant pancreatic cancers, and restoration of these microRNAs abrogates tumorigenesis. [Genes Dev] Panhematin Provides a Therapeutic Benefit in Experimental Pancreatitis Researchers tested the utility of Panhematin, a water-soluble hemin formulation, in activating and inducing pancreatic heme-oxygenase-1, and as a therapeutic agent in treating mouse acute pancreatitis. [Gut] Role for NQO1 and MnSOD in 17AAG-Induced Hsp90 Inhibition in Pancreatic Cancer Cells Data confirm the role of NQO1 in sensitivity to 17AAG and demonstrate that superoxide dismutase functions in conjunction with NQO1 to maintain intracellular levels of 17AAGH2, the active Hsp90 inhibitor derived from17AAG. [J Pharmacol Exp The] Overexpression of KAI1 Induces Autophagy and Increases MiaPaCa-2 Cell Survival Through the Phosphorylation of Extracellular Signal-Regulated Kinases By using transmission electron microscopy, confocal microscopy, and western blotting, researchers found that KAI1 can induce autophagy in a dose- and time-dependent manner in the human pancreatic cell line MiaPaCa-2. [Biochem Biophys Res Commun] The Neuronal Pentraxin II Gene (NPTX2) Inhibits Proliferation and Invasion of Pancreatic Cancer Cells In Vitro This study suggests that NPTX2, as a tumor-suppressor, plays an anti-tumor effect on pancreatic cancer and its low expression, due to promoter hypermethylation, may play a role in the tumorigenesis of pancreatic cancer.
