    LncRNA ARGI Contributes to Virus-Induced Pancreatic β Cell Inflammation through Transcriptional Activation of IFN-Stimulated Genes

    Upon a viral insult, ARGI was upregulated in the nuclei of pancreatic β cells and bound to CTCF to interact with the promoter and enhancer regions of IFNβ and interferon-stimulated genes.

    Differential Use of the Nkx2.2 NK2 Domain in Developing Pancreatic Islets and Neurons

    Researchers generated and analyzed mice in which the Nkx2.2 SD was mutated and found that the SD was required for normal pancreatic islet differentiation, but dispensable for most aspects of neuronal differentiation.

    Abstract

    Arginine 65 Methylation of Neurogenin 3 by PRMT1 Is Required for Pancreatic Endocrine Development of hESCs

    The authors demonstrated that arginine 65 methylation of Neurogenin 3 was a key molecular switch in human embryonic stem cells permitting their differentiation into pancreatic endocrine cells.

    Calcium/Calmodulin Dependent Protein Kinase IV in Trophoblast Cells under Insulin Resistance: Functional and Metabolomic Analyses

    Metabolomics analysis revealed that calcium/calmodulin dependent protein kinase IV (CAMK4) overexpression caused alterations of amino acid, lipid, and carbohydrate metabolism, which were important in gestational diabetes mellitus.

    Deficiency of the Metabolic Enzyme SCHAD in Pancreatic β-Cells Promotes Amino Acid-Sensitive Hypoglycemia

    To test the hypothesis that enzyme short-chain 3-hydroxyacyl-CoA dehydrogenase (SCHAD)-congenital hyperinsulinism of infancy arises from a specific defect in pancreatic β-cells, investigators created genetically engineered β-cell-specific or hepatocyte-specific SCHAD knockout mice.

    DUSP2 Recruits CSNK2A1 to Suppress AKT1-Mediated Apoptosis Resistance under Hypoxic Microenvironment in Pancreatic Cancer

    Dual-specificity phosphatase 2 (DUSP2) significantly promoted apoptosis in PDAC both in vitro and in vivo, mainly through AKT1 rather than ERK1/2.

    Abstract

    Chromatin Accessibility Uncovers KRAS-Driven FOSL2 Promoting Pancreatic Ductal Adenocarcinoma Progression through Up-Regulation of CCL28

    To characterize the epigenetic landscape of genetically engineered mouse models of PDAC, with or without KRAS and/or TP53 mutations, scientists employed ATAC-seq, H3K27ac ChIP-seq, and RNA-seq.

    NSUN2 Stimulates Tumor Progression via Enhancing TIAM2 mRNA Stability in Pancreatic Cancer

    Silence of NSUN2 by lentivirus weakened the capability of proliferation, migration and invasion of pancreatic cancer cells in vitro, and inhibited the growth and metastasis of xenograft tumors in vivo.

    Telomere-Related Prognostic Biomarkers for Survival Assessments in Pancreatic Cancer

    After calculating 502 telomere-associated differentially expressed genes, researchers constructed a three-gene prognostic signature that could be effectively applied to the prognostic classification of pancreatic cancer patients in multiple datasets.
