    Genetic and Pharmacologic Inhibition of ALDH1A3 as a Treatment of β-Cell Failure

    Scientists investigated the fate of A+ cells during pair-feeding by lineage-tracing, somatically ablated aldehyde dehydrogenase 1 isoform A3 (ALHD1A3) in diabetic β-cells, and used a novel selective ALDH1A3 inhibitor to treat diabetes.

    GDF15 Plays a Critical Role in Insulin Secretion in INS-1 Cells and Human Pancreatic Islets

    To examine the role of rowth differentiation factor-15 (GDF15) in β-cell function, bioinformatics analysis, and functional experiments involving GDF15 silencing and overexpression were performed in INS-1 cells and human islets.

    Abstract

    Tumor-Associated Nonmyelinating Schwann Cell–Expressed PVT1 Promotes Pancreatic Cancer Kynurenine Pathway and Tumor Immune Exclusion

    Scientists characterized the gene signature of tumor-associated nonmyelinating Schwann cells (TASc) in PDAC and indicated that the abundance of TASc was correlated with immune suppressive tumor microenvironment.

    Spatially Resolved Single-Cell Assessment of Pancreatic Cancer Expression Subtypes Reveals Co-Expressor Phenotypes and Extensive Intratumoral Heterogeneity

    To provide a deeper understanding of PDAC subtypes, the authors developed a multiplex immunofluorescence pipeline that quantified protein expression of six PDAC subtype markers and permitted spatially resolved, single-cell interrogation of pancreatic tumors.

    Abstract

    Arginase 1 Is a Key Driver of Immune Suppression in Pancreatic Cancer

    Researchers used a genetic and a pharmacologic approach to target Arginase 1 (Arg1) in pancreatic cancer to investigate Arg1’s metabolic function.

    Abstract

    Gemcitabine Promotes Autophagy and Lysosomal Function through ERK- and TFEB-Dependent Mechanisms

    Investigators found that gemcitabine elicited ERK-dependent autophagy in PDAC cells, but did not stimulate ERK activity or autophagy in non-tumoral human pancreatic epithelial cells.

    Targeting Chemoresistant Senescent Pancreatic Cancer Cells Improves Conventional Treatment Efficacy

    The authors described that gemcitabiner induced a senescent-like phenotype in highly chemoresistant pancreatic cancer cells in vitro and in xenografted tumors in vivo.

    New Thoughts and Findings on Invasion and Metastasis of Pancreatic Ductal Adenocarcinoma (PDAC) from Comparative Proteomics: Multi-Target Therapy

    Scientists conduct a systemic retrospective analysis of proteins that have been identified by comparative proteomics to be involved in the invasion and metastasis of PDAC over the past decade.
