    METTL16 Antagonizes MRE11-Mediated DNA End Resection and Confers Synthetic Lethality to PARP Inhibition in Pancreatic Ductal Adenocarcinoma

    Scientists reported that PDAC with elevated expression of METTL16, one of the ‘writers’ of RNA N6-methyladenosine modification, may benefit from poly-(ADP-ribose)-polymerase inhibitor treatment.

    The Pancreatic Clock Is a Key Determinant of Pancreatic Fibrosis Progression and Exocrine Dysfunction

    By using different models of CP established in mice with dysfunctional pancreatic clocks, researchers found that the local clock played an important role in chronic pancreatitis pathology, and genetic or external disruption of the pancreatic clock exacerbated fibrogenesis and exocrine insufficiency.

    E2F1 Transcription Factor Mediates a Link Between Fat and Islets To Promote β Cell Proliferation in Response to Acute Insulin Resistance

    Investigators reported the pathways utilized by β cells to robustly replicate in response to acute insulin resistance induced by S961, a pharmacological insulin receptor antagonist.

    Single-cell RNA Sequencing Reveals a Role for Reactive Oxygen Species and Peroxiredoxins in Fatty-Acid-Induced Rat Beta-Cell Proliferation

    The authors investigated the transcriptional mechanisms of beta-cell proliferation in response to fatty acids.The islet transcriptome was assessed by single cell RNA-sequencing.

    Abstract

    BMSCs Overexpressed ISL1 Reduces the Apoptosis of Islet Cells through ANLN Carrying Exosome, INHBA, and Caffeine

    By using ISL1-overexpressing bone marrow mesenchymal stem cells (BMSCs) and the subtherapeutic doses of islets for co-transplantation, scientists managed to reduce the apoptosis and improve the survival rate of islet grafts.

    Abstract

    PAF1 Cooperates With YAP1 in Metaplastic Ducts To Promote Pancreatic Cancer

    Researchers demonstrated that RNA polymerase II-associated factor 1 (PAF1) co-expressed and interacted with YAP1 specifically in metaplastic ducts of mouse cerulein- or KrasG12D-induced acinar-to-ductal metaplasia and human PDAC, but not in the normal pancreas.

    Downregulation of MMP1 Functions in Preventing Perineural Invasion of Pancreatic Cancer through Blocking the NT-3/TrkC Signaling Pathway

    Human pancreatic cancer PANC-1 cells were co-cultured with dorsal root ganglion in vitro. The expression of matrix metalloproteinase-1 (MMP1), epithelial–mesenchymal transition markers, Schwann cell markers, neurotrophic factors, NT-3, and TrkC were measured by qRT-PCR or Western blot.

    Insights from Multi-Omics Integration in Complex Disease Primary Tissues

    By highlighting recent integrative multi-omics studies in relevant tissues of four distinct complex diseases (type 2 diabetes, osteoarthritis, Alzheimer’s disease, and systemic lupus erythematosus), investigators outline the usefulness of the approach.
