    Revealing the Tissue-Level Complexity of Endogenous Glucagon-Like Peptide-1 Receptor Expression and Signaling

    Investigators generated mice harboring an enzyme self-label genome-edited into the endogenous Glp1r locus. They also rationally designed and tested various fluorescent dyes, spanning cyan to far-red wavelengths, for labeling performance in tissue.

    VGLL4 and MENIN Function as TEAD1 Corepressors to Block Pancreatic β Cell Proliferation

    Researchers demonstrated that while β cell-specific TEAD1 deletion resulted in a cell-autonomous increase of β cell proliferation, β cell-specific deletion of its canonical coactivators, YAP and TAZ, did not affect proliferation, suggesting the involvement of other cofactors.

    The Role of Preproglucagon Peptides in Regulating β-Cell Morphology and Responses to Streptozotocin-Induced Diabetes

    Scientists examined the role and source of preproglucagon peptides in β-cell function and in response to streptozotocin-induced hyperglycemia.

    Abstract

    A Microfluidic-Based PDAC Organoid System Reveals the Impact of Hypoxia in Response to Treatment

    Investigators established a PDAC platform that supported the understanding of treatment response of PDAC organoids in mono-, and co-culture with pancreatic stellate cells under hypoxic and normoxic conditions.

    Pancreatic Stellate Cell-Induced Gemcitabine Resistance in Pancreatic Cancer Is Associated with LDHA- and MCT4-Mediated Enhanced Glycolysis

    Human pancreatic cancer cell lines were exposed to three different pancreatic stellate cells-conditioned media, following either pre-treatment with glycolysis inhibitor NV-5440 or transfection for transient silencing of key glycolytic regulators.

    Combination of Serum Human Satellite RNA and miR-21-5p Levels as a Biomarker for Pancreatic Cancer

    The authors refined an older methodology of PDAC detection by simultaneously measuring the serum miR-21-5p level and HSATII RNA level to enhance the detection of PDAC.

    Cinchonine-Induced Cell Death in Pancreatic Cancer Cells by Downregulating RRP15

    Scientists showed that ribosomal RNA-processing 15 homolog (RRP15) expression was decreased in pancreatic cancer, and that RRP15 knockdown inhibited autophagy, and caused apoptosis in pancreatic cancer cells.

    Abstract

    Gallic Acid Markedly Stimulates GLUT1-Mediated Glucose Uptake by the AsPC-1 Pancreatic Cancer Cell Line

    Researchers tested the influence of phenolic acids on glucose and glutamine cellular uptake by a breast and a pancreatic, AsPC-1, cancer cell line.

    Tissue Clearing and 3D Reconstruction of Digitized, Serially Sectioned Slides Provide Novel Insights into Pancreatic Cancer

    Scientists describe the clinical features of pancreatic cancer, review techniques for clearing and the 3D reconstruction of digitized microscope slides, and provide examples that illustrate how 3D visualization of human pancreatic cancer at the microscopic level has revealed features not apparent in 2D microscopy.
