    Fetuin-A Excess Expression Amplifies Lipid Induced Apoptosis and β-Cell Damage

    Scientists screened the role of fetuin-A in survival of murine β-cells and validated the effect of fetuin-A release and lipid induced apoptosis in mouse insulinoma cell line MIN6.

    Abstract


    Angiopoietins Stimulate Pancreatic Islet Development from Stem Cells

    Researchers revealed that angiopoietins, including angiopoietin-1 and angiopoietin-2 permitted the generation of islets from induced pluripotent stem cells with elevated glucose responsiveness, a hallmark of mature islets.

    MafA, NeuroD1, and HNF1β Synergistically Activate Slc2a2 (Glut2) Gene in β-Cells

    Scientists found that an evolutionarily conserved region located approximately 40 kbp downstream of the transcription start site of Slc2a2 functioned as an active enhancer in the MIN6 β-cell line.

    Abstract

    Dexamethasone Induces Pancreatic β-Cell Apoptosis through Upregulation of TRAIL Death Receptor

    Researchers investigated the mechanism of dexamethasone-induced pancreatic β-cell apoptosis through the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) pathway in cultured cells and isolated mouse islets.
    [Journal of Molecular Endocrinology]

    Abstract

    Oxytocin Signal Contributes to the Adaptative Growth of Islets during Gestation

    Gestating and non-gestating mice were used to evaluate the in vivo effect of oxytocin signal on β-cells during pregnancy. In vitro experiments were performed on INS-1 insulinoma cells.

    Multi-Omics Profiling of Living Human Pancreatic Islet Donors Reveals Heterogeneous Beta Cell Trajectories towards Type 2 Diabetes

    Scientists conducted a comprehensive multi-omics analysis of pancreatic islets obtained from metabolically profiled pancreatectomized living human donors stratified along the glycemic continuum, from normoglycemia to type 2 diabetes.

    TP53
    Missense Mutations in PDAC Are Associated with Enhanced Fibrosis and an Immunosuppressive Microenvironment

    Researchers suggested that missense p53 mutations may have contributed to worse PDAC prognosis by promoting a more vigorous fibrotic tumor microenvironment and impeded the ability of the immune system to eliminate the cancer cells.

    Abstract

    Integrative Analysis Reveals Clinically Relevant Molecular Fingerprints in Pancreatic Cancer

    Scientists screened multi-layer molecular data of 36 pancreatic cancer cell lines, including gene mutation, gene expression, miRNA expression, and protein profiles.

    Abstract

    GDP Induces PANC-1 Human Pancreatic Cancer Cell Death Preferentially under Nutrient Starvation by Inhibiting PI3K/Akt/mTOR/Autophagy Signaling Pathway

    Geranyl-2,4-dihydroxy-6-phenethylbenzoate (GDP), isolated from Boesenbergia pandurata rhizomes, exhibited potent preferential cytotoxicity against PANC-1 human pancreatic cancer cells under nutrition starvation conditions.
