    MET Targeting Antibody-Drug Conjugate Overcomes Gemcitabine Resistance in Pancreatic Cancer

    Scientists evaluated the efficacy of TR1801-ADC, a newly developed ADC composed of a MET antibody conjugated to the highly potent pyrrolobenzodiazepine toxin-linker Tesirine. They first evaluated MET expression and subcellular localization in pancreatic cancer cell lines, human tumors and patient derived xenografts.

    DIABETES & PANCREATITIS

    SIX2 and SIX3 Coordinately Regulate Functional Maturity and Fate of Human Pancreatic β Cells

    Researchers showed that shRNA-mediated SIX2 or SIX3 suppression in human pancreatic adult islets impaired insulin secretion.

    Abstract

    Essential Roles of Insulin and IGF-1 Receptors during Embryonic Lineage Development

    To directly define the roles of insulin and IGF-1 receptors in the maintenance of pluripotency and differentiation of stem cells, scientists knocked out both the receptors in induced pluripotent stem cells.

    Abstract

    Dermal Fibroblasts Cultured from Donors with Type 2 Diabetes Mellitus Retain an Epigenetic Memory Associated with Poor Wound Healing Responses

    Dermal fibroblasts (DF) are critical for effective wound healing, the authors sought to establish whether there were any differences in DF cultured from type 2 diabetes mellitus donors or those without diabetes.

    ATDC
    Binds to KEAP1 to Drive NRF2-Mediated Tumorigenesis and Chemoresistance in Pancreatic Cancer

    Researchers revealed that increased ataxia-telangiectasia group D-associated gene (ATDC) levels protected cancer cells from reactive oxygen species via stabilization of nuclear factor erythroid 2-related factor 2 (NRF2).

    Abstract

    Combining
    NanoKnife with M1 Oncolytic Virus Enhances Anticancer Activity in Pancreatic Cancer

    Investigators evaluated improvements to therapeutic efficacy through combination therapy incorporating NanoKnife and M1 virus. They showed that irreversible electroporation triggered reactive oxygen species-dependent apoptosis in pancreatic cancer cells mediated by phosphatidylinositol-3-kinase/protein kinase B pathway suppression.

    Overcoming
    Hypoxia-Induced Resistance of Pancreatic and Lung Tumor Cells by Disrupting the PERK-NRF2-HIF-Axis

    The authors generated human cancer cell lines of pancreatic and lung origin carrying an inducible shRNA against NRF2 and PERK. They report that PERK-related phosphorylation of NRF2 was only critical in Keap1 wildtype cells to escape its degradation, but showed no direct effect on nuclear import or transcriptional activity of NRF2.

    Dopamine
    Improves Chemotherapeutic Efficacy for Pancreatic Cancer by Regulating Macrophage-Derived Inflammations

    The roles and mechanisms of dopamine to affect the chemotherapeutic efficacy for pancreatic cancer were studied. Multi-omics results revealed that there was a tumor-promoting vicious cycle involving murine pancreatic cancer cells and tumor-associated macrophages.

    Abstract

    Assessing ZNF154
    Methylation in Patient Plasma as a Multicancer Marker in Liquid Biopsies from Colon, Liver, Ovarian and Pancreatic Cancer Patients

    Investigators assessed the effectiveness of hypermethylation at the CpG island of ZNF154, a previously reported multi-cancer specific signature for use in a blood-based cancer detection assay.

    The BET Family in Immunity and Disease

    Investigators cover the accumulating data about the roles of the bromodomain and extraterminal domain (BET) family in innate immunity and discuss the attractive prospect of manipulating the BET family as a new treatment for disease.
