    Epigenetic Plasticity Cooperates with Cell-Cell Interactions to Direct Pancreatic Tumorigenesis

    To investigate the origins and impact of epigenetic plasticity during early neoplasia, the authors performed single-cell analyses on normal, inflamed, premalignant, and malignant tissues in autochthonous models of pancreatic cancer.

    Vitamin K-Dependent Carboxylation Regulates Ca2+ Flux and Adaptation to Metabolic Stress in β Cells

    Researchers showed that mouse β cells lacking γ-carboxylation failed to adapt their insulin secretion in the context of age-related insulin resistance or diet-induced β cell stress.

    Zhx2 Maintains Islet β Cell Mass and Function by Transcriptionally Regulating Pax6

    Investigators reported that zinc finger homeobox 2 (Zhx2) orchestrated β cell mass and function by regulating paired box protein pax-6 (Pax6).

    VGF Nerve Growth Factor Inducible Has the Potential to Protect Pancreatic β-Cells

    Researchers elucidated the β-cell protective effect of VGF nerve growth factor inducible (VGF) on a streptozotocin-induced diabetic model using VGF-overexpressing mice and also examined the therapeutic effect by a small molecule, SUN N8075, which is an inducer of VGF.

    Abstract

    SUMO Specific Peptidase 3 Halts Pancreatic Ductal Adenocarcinoma Metastasis via deSUMOylating DKC1

    Scientists dentified SUMO-specific protease 3 (SENP3) as a potential suppressor of PDAC progression through an in vivo metastatic model. Further studies revealed that SENP3 inhibited PDAC invasion in a SUMO system dependent fashion.

    Pancreatic Cancer-Derived Small Extracellular Vesical Ezrin Activates Fibroblasts to Exacerbate Cancer Metastasis through STAT3 and YAP-1 Signaling Pathways

    Investigators reported that ezrin expression in PDAC cell-derived small extracellular vesicles could activate fibroblasts, resulting in increased migration ability and high expression of α-SMA, PDGFRB, and high production of extracellular matrix in fibroblasts.

    METTL3 Suppresses Pancreatic Ductal Adenocarcinoma Progression through Activating Endogenous dsRNA-Induced Anti-Tumor Immunity

    The authors demonstrated that METTL3, the key regulator of N6-methyladenosine modification, was downregulated in PDAC, and negatively correlated with PDAC malignant features.

    Abstract

    Combinatorial Immunotherapy with Gemcitabine and Ex Vivo-Expanded NK Cells Induces Anti-Tumor Effects in Pancreatic Cancer

    Natural killer (NK) cells expanded in this method showed greater cytotoxicity than resting NK cells, when co-cultured with pancreatic cancer cell lines.

    SPOCK2 Gene Expression Is Downregulated in Pancreatic Ductal Adenocarcinoma Cells and Correlates with Prognosis of Patients with Pancreatic Cancer

    Scientists explored the possible role of SPOCK2 in the pathogenesis of PDAC and evaluated SPOCK2 in seven PDAC cell lines and one normal pancreatic cell line using quantitative RT-PCR.

    Petite Integration Factor 1 Knockdown Enhances Gemcitabine Sensitivity in Pancreatic Cancer Cells via Increasing DNA Damage

    Petite integration factor 1 (PIF1) expression was upregulated in pancreatic cancer tissues and cells. Knockdown of PIF1 exhibited a repressive impact on the viability of AsPC-1 and PANC-1 cells.
