    Ductal
    Ngn3-Expressing Progenitors Contribute to Adult β Cell Neogenesis in the Pancreas

    Lineage tracing using the Neurogenin3 (Ngn3)-CreERT line identified ductal cells expressing the endocrine master transcription factor Ngn3 that were positive for the δ cell marker somatostatin and occasionally co-expressed insulin.

    Therapy-Naïve
    and Radioresistant 3D Pancreatic Cancer Cell Cultures Are Effectively Radiosensitized by β1 Integrin Targeting

    In a panel of 3D, extracellular matrix based PDAC cell cultures, β1 integrin was inhibited by antibodies or siRNA-mediated knockdown. Together with X-ray irradiation and specific chemotherapies, scientists determined 3D colony formation capacity in therapy-naïve and radioresistant PDAC cultures.

    The
    β-Cell Glucose Toxicity Hypothesis: Attractive but Difficult to Prove

    β cells in the hyperglycemic environment of diabetes have marked changes in phenotype and function that are largely reversible if glucose levels can be returned to normal. A leading hypothesis is that these changes are caused by the elevated glucose levels leading to the concept of glucose toxicity.
