    Major β Cell-Specific Functions of NKX2.2 Are Mediated via the NK2-Specific Domain

    Mutation of the endogenous NKX2.2- specific domain prevented the developmental progression of β cell precursors into mature, insulin-expressing β cells, resulting in overt neonatal diabetes.

    Abstract

    Deletion of Carboxypeptidase E in Beta Cells Disrupts Proinsulin Processing but Does Not Lead to Spontaneous Development of Diabetes in Mice

    Pancreatic beta cell-specific Cpe knockout mice (βCpeKO) lacked mature insulin granules and had elevated proinsulin in plasma; however, glucose-and KCl-stimulated insulin secretion in βCpeKO islets remained intact.

    Abstract

    Optimization of a Glucagon-Like Peptide 1 Receptor Antagonist Antibody for Treatment of Hyperinsulinism

    Researchers designed a combinatorial variant antibody library to optimize the activity of TB-001-003 against glucagon-like peptide 1 receptor (GLP-1R), and performed phage-display on cells overexpressing GLP-1R.

    Abstract

    Trans-Palmitoleic Acid, a Dairy Fat Biomarker, Stimulates Insulin Secretion and Activates G Protein-Coupled Receptors with a Different Mechanism from the cis Isomer

    Scientists examined the potency of both palmitoleic acid (POA) isomers to potentiate insulin secretion in murine and human pancreatic β cell lines, and whether POA isomers activated G protein-coupled receptors proposed as potential targets for type 2 diabetes mellitus treatment.

    AKBA Alleviates Experimental Pancreatitis by Inhibiting Oxidative Stress in MacrophagestThrough the Nrf2/HO-1 Pathway

    In a caerulein-induced mouse model of acute pancreatitis, treatment with Acetyl-11-keto-β-boswellic acid (AKBA) reduced blood amylase and lipase activity and ameliorated pancreatic tissue histological and pathological features.

    Simultaneous Delivery of Dual Inhibitors of DNA Damage Repair Sensitizes Pancreatic Cancer Response to Irreversible Electroporation

    The combination of irreversible electroporation and a custom micelle nanoformulation significantly prolonged animal survival in both subcutaneous and orthotopic murine PDAC models, and elicited CD8+ T cell-mediated antitumor immunity with a sustained antitumor memory.

    NFIC Regulates Ribosomal Biology and ER Stress in Pancreatic Acinar Cells and Restrains PDAC Initiation

    Investigators identified NFIC as a NR5A2 interactor and regulator of acinar differentiation. NFIC binding sites were enriched in NR5A2 ChIP-Sequencing peaks.

    Mutant KRAS Mediates circARFGEF2 Biogenesis to Promote Lymphatic Metastasis of Pancreatic Ductal Adenocarcinoma

    Circular RNA ARFGEF2 (CircARFGEF2) overexpression significantly facilitated KRASG12D PDAC lymph node metastasis in vitro and in vivo.

    Abstract

    NUSAP1-LDHA-Glycolysis-Lactate Feedforward Loop Promotes Warburg Effect and Metastasis in Pancreatic Ductal Adenocarcinoma

    The function of nucleolar and spindle associated protein 1 (NUSAP1) in PDAC progression was clarified by single-cell RNA-seq and further experiments in vitro, xenograft mouse model, spontaneous PDAC mice model, and human tissue microarray.
