TOP STORYA Multiscale Map of the Stem Cell State in Pancreatic Adenocarcinoma Researchers used RNA sequencing (seq), chromatin immunoprecipitation-seq, and genome-wide CRISPR analysis to map the molecular dependencies of pancreatic cancer stem cells, highly therapy-resistant cells that preferentially drove tumorigenesis and progression.

PUBLICATIONS(Ranked by impact factor of the journal)DIABETES & PANCREATITISJUND Regulates Pancreatic β Cell Survival during Metabolic Stress Using a panel of diabetes-associated stressors, JUND was found to be upregulated in mouse islets cultured with high concentrations of glucose and free fatty acid, but not after treatment with hydrogen peroxide or thapsigargin. [Mol Metab] Full Article Apolipoprotein A-I (apoA-I) treatment improved glucose-stimulated insulin secretion in β-double knockout but not control mouse islets. Plasma lipid and lipoprotein levels and islet cholesterol levels were also unaffected by treatment with apoA-I. [FASEB J] Abstract Human induced pluripotent stem cells were differentiated into pancreatic exocrine cells by stage-specific treatment with growth factors and chemical compounds, and the differentiated pancreatic cells were implanted into the gastric submucosal space of nude rats. [Sci Rep] Full Article Researchers studied structure-self-assembly relationships focusing on position 21 to gain detailed insights into the molecular mechanisms of islet amyloid polypeptide self-assembly and to probe the conformational nature of the toxic assemblies associated with β-cell death. [J Biol Chem] Abstract | Full Article PANCREATIC CANCERScientists report that combined ablation of EGFR and c-RAF expression resulted in complete regression of a significant percentage of pancreatic ductal adenocarcinoma tumors driven by Kras/Trp53 mutations in genetically engineered mice. [Cancer Cell] Abstract | Press Release | Graphical Abstract Using mass spectrometry, bioinformatics analysis, co-immunoprecipitation, and pulldown assays, investigators discovered a novel, direct binding interaction between the cytoplasmic tail of podocalyxin and the large GTPase dynamin-2 at its GTPase, middle, and pleckstrin homology domains. [Cancer Res] Abstract Chaperone-Mediated Autophagy Degradation of IGF-1Rβ Induced by NVP-AUY922 in Pancreatic Cancer The authors found that the heat shock protein 90 α inhibitor NVP-AUY922 effectively downregulated and destabilized the insulin-like growth factor 1 receptor (IGF-1R) β protein, substantially reduced the levels of downstream signaling molecules, and resulted in growth inhibition and apoptosis in IGF-1Rβ-overexpressing pancreatic cancer cells. [Cell Mol Life Sci] Abstract Development of an Anti-BAG3 Humanized Antibody for Treatment of Pancreatic Cancer Researchers showed that the humanized anti-BAG3 antibody, named BAG3-H2L4, abrogated BAG3 binding to macrophages and subsequent release of IL-6. Furthermore, it specifically localized into tumor tissues and significantly inhibited the growth of MiaPaCa-2 pancreatic cancer cell xenografts. [Mol Oncol] Abstract | Full Article In MIA Paca-2 cells, silencing of SP1 induced a reduction of LOXL2 expression, whereas LOXL2 silencing did not lead to a decrease in the expression of SP1. Chromatin immunoprecipitation assay demonstrated the binding of SP1 to LOXL2 promoter.

REVIEWSEpigenetics in Human Obesity and Type 2 Diabetes The authors summarize epigenetic signatures obtained from human tissues of relevance for metabolism in relation to obesity and type 2 diabetes. [Cell Metab] Full Article Protein Tyrosine Phosphatases: Promising Targets in Pancreatic Ductal Adenocarcinoma Investigators discuss the role of protein tyrosine phosphatases in tumorigenesis as tumor suppressor and oncogenic proteins. They focus on the differential expression of these proteins in pancreatic ductal adenocarcinoma, as well as their clinical implications and possible targeting for pharmacological inhibition in cancer therapy.

POLICY NEWSInfluential Senator Asks NSF for Data on Threat from Foreign Influences The National Science Foundation (NSF) has joined the list of federal agencies that Senator Chuck Grassley has asked for explanations of how they are preventing foreign scientists from ripping off US taxpayers. [ScienceInsider] Editorial Indonesian Mega-Science Agency in the Balance as Election Begins Indonesians will vote in a national election that pits two old rivals against each other. The stakes are high for science. President Joko Widodo says that if he is re-elected, he will overhaul how much of the country’s research is organized and funded. The main opposition candidate has been silent on science so far. [Nature News] Editorial
