    Proteasomal Degradation of Wild-Type Proinsulin in Pancreatic Beta Cells

    Investigators reported that although proteasomal inhibition immediately downregulated new proinsulin biosynthesis, it nevertheless acutely increased beta cell proinsulin levels in pancreatic beta cell lines, rodent pancreatic islets, and human islets.

    SF3B1 Facilitates HIF1-Signaling and Promotes Malignancy in Pancreatic Cancer

    Scientists demonstrated that a reduction in SF3B1 levels via monoallelic deletion of Sf3b1 impeded tumor formation and progression via impaired hypoxia-inducible factor (HIF) signaling in a mouse model for pancreatic cancer.

    Genome-Wide CRISPR Screen Identifies MTA3 as an Inducer of Gemcitabine Resistance in Pancreatic Ductal Adenocarcinoma

    Using CRISPR/Cas9 activation library screen, the authors discovered that MTA3 mediated the gemcitabine (GEM) resistance of PDAC and thus might be a potential therapeutic target for combination chemotherapy.

    Abstract

    LINC00941 Promotes Pancreatic Cancer Malignancy by Interacting With ANXA2 and Suppressing NEDD4L-Mediated Degradation of ANXA2

    Using functional experiments and mice models, scientists discovered that LINC00941 overexpression promoted pancreatic cancer (PC) proliferation and metastasis.

    miR-222-3p-Containing Macrophage-Derived Extracellular Vesicles Confer Gemcitabine Resistance via TSC1-Mediated mTOR/AKT/PI3K Pathway in Pancreatic Cancer

    Co-culture of pancreatic cancer cells with M2 macrophage-derived extracellular vesicles enriched with miR-222-3p suppressed the sensitivity to gemcitabine, accompanied by diminished apoptosis and promoted proliferation.

    ESE3-Positive PSCs Drive Pancreatic Cancer Fibrosis, Chemoresistance and Poor Prognosis via Tumor–Stromal IL-1β/NF–κB/ESE3 Signaling Axis

    Scientists reported that epithelium-specific E-twenty six factor 3 (ESE3) expression increased in pancreatic stellate cells (PSCs) in PDAC tissues compared with those in normal PSCs.

    Overexpression of Dermokine-α Enhances the Proliferation and Epithelial-Mesenchymal Transition of Pancreatic Tumor Cells

    Using CCK-8, colony formation, RTCA test, wound healing, as well as transwell test, researchers demonstrated that the overexpression of dermokine-α (DMKN-α) enhanced the proliferation, migration, invasion, and EMT of pancreatic cancer cells.

    Abstract

    Tomentosin Induces Apoptosis in Pancreatic Cancer Cells Through Increasing Reactive Oxygen Species and Decreasing Mitochondrial Membrane Potential

    Investigators evaluate the effect of tomentosin on the migration and invasion of pancreatic cancer cells.

    Australian Study to Use New Technology in Bid to Improve Understanding of Pancreatic Cancer

    The researchers from QIMR Berghofer, Griffith University and the Garvan Institute of Medical Research will be among the first in the world to use spatial transcriptomics technology to study how cancer cells invade nerves in the pancreas and interact with immune cells, in a bid to better understand how the cancer spreads and causes pain.

    New MUSC Grant Fuels Research to Crack Genetic Code on Deadly Cancer

    The Pancreatic Cancer Action Network awarded $10.5 million in new research grants nationally, including $250,000 in a Career Development Award to Dr. Aaron Hobbs at MUSC for his work looking at a peculiar mutation in some pancreatic tumors that could become a biomarker and a potential target for therapy, a first for South Carolina.
