    BefA, a Microbiota-Secreted Membrane Disrupter, Disseminates to the Pancreas and Increases β Cell Mass

    BefA disseminated systemically by multiple anatomic routes to act directly on pancreatic islets. A BefA mutant impaired in membrane disruption failed to expand β cells, whereas the pore-forming host defense protein, Reg3, stimulated β cell proliferation.

    Single-Cell RNA-Seq Transcriptomic Landscape of Human and Mouse Islets and Pathological Alterations of Diabetes

    The authors isolated pancreatic islets from the control and type 2 diabetes mice for scRNA-seq and retrieved multiple datasets from the open databases. The complete islets cell landscape and robust marker genes and transcription factors of each endocrine cell type were identified.

    A Novel Protein RASON Encoded by a lncRNA Controls Oncogenic RAS Signaling in KRAS Mutant Cancers

    Scientists reported that RAS-ON (RASON) was a positive regulator of oncogenic RAS signaling, and was aberrantly overexpressed in PDAC patients, promoting proliferation of human PDAC cell lines in vitro and tumor growth in vivo.

    Corynoxine Suppresses Pancreatic Cancer Growth Primarily via Ros-p38 Mediated Cytostatic Effects

    The effects of Corynoxine were evaluated on two pancreatic cancer cell lines, Patu-8988 and Panc-1, using cell viability analysis, EdU staining, TUNEL assay, colony formation assay, and flow cytometry.

    ATM- and ATR-Induced Primary Ciliogenesis Promotes Cisplatin Resistance in Pancreatic Ductal Adenocarcinoma

    Investigators showed that cisplatin-resistant PDAC regrew primary cilia. Additionally, genetic or pharmacological disruption of primary cilia sensitized PDAC to cisplatin treatment.

    Abstract

    Generation of Murine Tumour-Reactive T Cells by Co-Culturing Murine Pancreatic Cancer Organoids and Peripheral Blood Lymphocytes

    15 hub genes were identified, among which inducible T cell co‑stimulator was indicated to serve a role in the most pivotal immunity pathways. pSS was markedly associated with inflammatory pathways.

    Antibiotics in the Pathogenesis of Diabetes and Inflammatory Diseases of the Gastrointestinal Tract

    Scientists examine the association between the use of antibiotics and the onset and development of both type 1 and type 2 diabetes, inflammatory bowel disease, including ulcerative colitis and Crohn’s disease, as well as coeliac disease and eosinophilic oesophagitis.
