TOP STORYROBO2 Is a Stroma Suppressor Gene in the Pancreas and Acts via TGF-β Signaling Scientists reported that in pancreatitis and pancreatic ductal adenocarcinoma mouse models, epithelial Robo2 expression was lost while Robo1 expression became most prominent in the stroma.

PUBLICATIONS(Ranked by impact factor of the journal)DIABETES & PANCREATITISRobo Signaling Controls Pancreatic Progenitor Identity by Regulating Tead Transcription Factors Researchers identified Slit/Robo signaling as a key regulator of pancreatic progenitor identity. They found that Robo1 and Robo2 were required for preserving pancreatic cell identity shortly after fate induction and, subsequently, for expansion of the pancreatic progenitor pool in the mouse. [Nat Commun] Full Article Transcriptional Heterogeneity of Beta Cells in the Intact Pancreas Scientists developed an optimized protocol for single-molecule transcript imaging in the intact pancreas and used it to identify a sub-population of “extreme” beta cells with elevated mRNA levels of insulin and other secretory genes. [Dev Cell] Full Article | Graphical Abstract β Cell Replacement after Gene Editing of a Neonatal Diabetes-Causing Mutation at the Insulin Locus Investigators generated induced pluripotent stem cells from fibroblasts of a patient with permanent neonatal diabetes mellitus and undetectable insulin at birth due to a homozygous mutation in the translation start site of the insulin gene. [Stem Cell Reports] Full Article Dexamethasone-induced protein (DEXI)-silenced beta cells exposed to a synthetic double-stranded RNA showed reduced activation of signal transducer and activator of transcription (STAT) 1 and lower production of proinflammatory chemokines that was preceded by a reduction in IFNβ levels. [Diabetologia] Full Article PANCREATIC CANCERResearchers investigated whether the hypoxic niche enhanced gemcitabine-induced stemness and acquired resistance in pancreatic cancer cells by activating the AKT/Notch1 signaling cascade. [J Exp Clin Cancer Res] Full Article Gemcitabine and HIF1α-siRNA loaded GE-11 peptide conjugated liposome was successfully prepared and evaluated for its antitumor efficacy in pancreatic cancer cells. GE11 increased the targeting specificity of the liposome carrier and increased intracellular concentrations in the cancer cells. [J Drug Target] Abstract The expression of autotaxin in pancreatic neuroendocrine neoplasm (pNEN) tissues and the pNEN cell line BON1 was analysed by Western blot, PCR and immunocytochemistry upon exposure to interleukin-6. [Endocr Connect] Full Article Prolyl hydroxylase domain 3 overexpression suppressed hypoxia-inducible factor (HIF)-1α protein expression and EGFR phosphorylation and enhanced the 2 Gy irradiation-mediated reductions in HIF-1α and phosphorylated EGFR under either normoxic or hypoxic conditions. [Onco Targets Ther] Full Article Expression of TM4SF5 induced increased cell proliferation and motility in vitro. Injection of the TM4SF5 peptide vaccine induced the production of anti-hTM4SF5 antibodies and reduced the growth of pancreatic tumors in mice established by subcutaneous injection of the TM4SF5-expressing mouse pancreatic cancer cell line.

REVIEWSModeling the Endocrine Pancreas in Health and Disease Investigators discuss diverse modeling systems across different species that provide spatial and temporal resolution of cellular and molecular mechanisms to understand the evolutionary conserved genotype-phenotype relationship and translate them to humans. [Nat Rev Endocrinol] Abstract Oral Semaglutide for the Treatment of Type 2 Diabetes The authors review oral semaglutide – an experimental glucagon-like peptide-1 receptor agonist in Phase-III clinical development. Available pharmacological and clinical data of the drug are reviewed, and important end-points described.

INDUSTRY NEWSPharmaCyte Biotech, Inc. announced that it has engaged cGMP Validation L.L.C. to assist in the preparation of the Investigational New Drug application (IND) that must be submitted to and approved by the FDA before PharmaCyte can begin its planned clinical trial in patients with locally advanced, non-metastatic, inoperable pancreatic cancer. [PharmaCyte Biotech, Inc.] Press Release Quest PharmaTech Inc.’s targeted cancer therapy technology includes two potential treatments, AR 9.6, an antibody licensed from the University of Nebraska Medical Center that binds to and blocks oncogenic activities of MUC16, and ACP-2127, which targets CDK/mTOR receptors. Both candidates are being developed for the treatment of pancreatic cancer. [Quest PharmaTech Inc.] Press Release Moleculin Announces New Data Further Supporting Its Lead Drug for Treating Pancreatic Cancer Moleculin Biotech, Inc. announced that data from an independent test in animal models confirmed that its immuno-stimulating STAT3 inhibitor achieves disproportionately high accumulation in the pancreas.

POLICY NEWSResearchers Sign Petition Backing Plans to End Paywalls More than 1,400 researchers have signed an online letter backing the principles of Plan S, the bold open-access initiative led by research agencies who say that, by 2020, papers resulting from their funding should be immediately free to read on publication. [Nature News] Editorial Data Sharing in Action: When Drug Companies Open Their Trial Vaults Clinical trials generate tons of data that never see the light of day, but an initiative spearheaded by researchers at Yale University is trying to change that. Since 2011, the Yale University Open Data Access Project has developed a platform that allows external researchers to gain access to clinical trials data from pharmaceutical companies.
