    Nutrient Restriction-Activated Fra-2 Promotes Tumor Progression via IGF1R in miR-15a Downmodulated Pancreatic Ductal Adenocarcinoma

    Investigators identified the transcription factor Fos-related antigen-2 (Fra-2) as a miR-15a target mediating the adaptive mechanism of PDAC to nutrient deprivation.

    A Novel Approach for Pancreas Transcriptomics Reveals the Cellular Landscape in Homeostasis and Acute Pancreatitis

    The authors introduced FixNCut, a scRNA-seq approach where tissue is reversibly fixed with dithiobis(succinimidyl propionate) prior to dissociation and single-cell preparation. They applied FixNCut to an established mouse model of acute pancreatitis.

    Hypoimmune Islets Achieve Insulin Independence after Allogeneic Transplantation in a Fully Immunocompetent Non-Human Primate

    Researchers reported that allogeneic transplantation of genetically engineered, primary, hypoimmune, pseudo-islets resulted in their engraftment into a fully immunocompetent, diabetic non-human primate wherein they provided stable endocrine function and enabled insulin independence.

    DRAK2 Suppresses Autophagy by Phosphorylating ULK1 at Ser56 to Diminish Pancreatic β Cell Function upon Overnutrition

    Investigators identified a marked up-regulation of DAP-related apoptosis-inducing kinase-2 (DRAK2) in pancreatic tissue across humans, macaques, and mice with type 2 diabetes.

    Abstract

    ISR Inhibition Reverses Pancreatic β-Cell Failure in Wolfram Syndrome Models

    Human pluripotent stem cell derived pancreatic islets harboring WFS1 deficiency and mouse model of β cell specific Wfs1 knockout were applied to model β-cell failure in wolfram syndrome.

    Abstract

    Concurrent Targeting of GSK3 and MEK as a Therapeutic Strategy to Treat Pancreatic Ductal Adenocarcinoma

    Scientists identified Glycogen synthase kinase 3 (GSK3) as a therapeutic target through a whole-body genetic screening utilizing a ‘4-hit’ Drosophila model mimicking the PDAC genotype.
