    MKP1 Promotes Nonalcoholic Steatohepatitis by Suppressing AMPK Activity Through LKB1 Nuclear Retention

    Researchers uncovered a mechanism of adenosine monophosphate-activated protein kinase expression in the nonalcoholic fatty liver disease to nonalcoholic steatohepatitis transition, which was mediated by a nuclear mitogen-activated protein kinase (MAPK) phosphatase-1 (MKP1)/p38 MAPK-LKB1 axis.

    Single Cell Multiomic Analysis Reveals Diabetes-Associated β-Cell Heterogeneity Driven by HNF1A

    Scientists integrated single-cell transcriptome, single-nuclei chromatin accessibility, and cell-type specific 3D genome profiles from human islets and identified type II diabetes-associated β-cell heterogeneity at both transcriptomic and epigenomic levels.

    Self-Organized Insulin-Producing β-Cells Differentiated from Human Omentum-Derived Stem Cells and Their In Vivo Therapeutic Potential

    Investigators evaluated the in vitro differentiation potential of human omentum-derived mesenchymal stem cells cultured on an fibroblast growth factor 2-immobilized matrix and a round-bottom plate. Further, the in vivo therapeutic efficacy of the β-cells transplanted into kidney capsules was evaluated.

    A Bovine Milk-Derived Peptide Ameliorates Pancreatic β-Cell Dedifferentiation Through PI3K/Akt/FOXO1 Signaling in Type 2 Diabetes

    The lacto-ghrestatin derived nonapeptide, a bioactive peptide derived from lacto-ghrestatin in bovine milk with the sequence of LIVTQTMKG, was investigated to determine its effects on islet β-cell dedifferentiation and associated mechanisms in type 2 diabetes mellitus.

    Abstract

    Acid-Base Homeostasis Orchestrated by NHE1 Defines Pancreatic Stellate Cell Phenotype in Pancreatic Cancer

    Researchers hypothesized that disrupting the pH landscape during PDAC progression triggered pancreatic stellate cells and cancer-associated fibroblasts to induce PDAC fibrosis.

    ST6GAL1 Sialyltransferase Promotes Acinar to Ductal Metaplasia and Pancreatic Cancer Progression

    Investigators determined that the ST6GAL1 sialyltransferase, which adds α2,6-linked sialic acids to N-glycosylated proteins, was upregulated in patients with early-stage PDAC, and further increased in advanced disease.

    Knockdown of SIX4 Inhibits Pancreatic Cancer Cells via Apoptosis Induction

    Scientists investigated siRNA-mediated knockdown effects of sine oculis homeobox 4 (SIX4) on pancreatic cancer cells and underlying molecular mechanisms.

    Abstract

    Aberrant Expression of CKS2 Induced by ELK1 Contributes to Malignant Progression of Pancreatic Cancer

    Researchers investigated the functional role of cyclin-dependent kinase subunit 2 in pancreatic cancer (PC). An analysis of abnormally expressed genes and their prognostic value for PC was performed by using the Gene Expression Profiling Interactive Analysis database and performing immunohistochemical staining.

    A DIY ‘Bionic Pancreas’ Is Changing Diabetes Care — What’s Next?

    Ten years ago, a tech-savvy group of people with type 1 diabetes decided to pursue a DIY approach to their own treatment. They knew that a fairly straightforward piece of software could make their lives much easier, but no companies were developing it quickly enough.
