    Integrating Single-Cell Imaging and RNA Sequencing Datasets Links Differentiation and Morphogenetic Dynamics of Human Pancreatic Endocrine Progenitors

    By monitoring both eurogenin 3 (NEUROG3) gene expression and protein in single cells using a knockin dual reporter in 2D and 3D models of human pancreas development, researchers showed an approximately two-fold slower expression of human NEUROG3 than that of the mouse.

    A TGF-β/KLF10 Signaling Axis Regulates Atrophy-Associated Genes to Induce Muscle Wasting in Pancreatic Cancer

    In vivo studies leveraging orthotopic implantation of pancreas cancer cells into wild-type and KLF10 KO mice revealed significant preservation of lean mass and robust suppression of pro-atrophy muscle-specific ubiquitin ligases Trim63 and Fbxo32.

    Abstract

    Modeling Islet Enhancers Using Deep Learning Identifies Candidate Causal Variants at Loci Associated with T2D and Glycemic Traits

    Focusing on pancreatic islets, a type 2 diabetes relevant tissue, researchers showed that their model learned islet-specific transcription factor regulatory patterns and could be used to prioritize candidate causal variants.

    Abstract

    Pancreatic Acinar Cell Fate Relies on System xC to Prevent Ferroptosis During Stress

    RNAseq analysis indicated that, in both human and mice, early acinar cell dedifferentiation was accompanied by multiple pathways related to cell survival that were highly enriched, and where SLC7A11 was transiently upregulated.

    An Integrated Map of Cell Type-Specific Gene Expression in Pancreatic Islets

    The authors presented an integrated map of islet cell type-specific gene expression from 192,203 cells from single cell RNA-sequencing of 65 non-diabetic, type 1 diabetes autoantibody positive, type 1 diabetic, and type 2 diabetic donors from the Human Pancreas Analysis Program.

    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.

    Anticancer Activities of DNA-Alkylating Pyrrole–Imidazole Polyamide Analogs Targeting RUNX Transcription Factors against p53-Mutated Pancreatic Cancer PANC-1 Cells

    Investigators evaluated the anticancer effects of 1 and its analogs 2–4 against p53-mutated PANC-1 pancreatic cancer cells. They found that they possessed different DNA-alkylating properties in vitro.

    Multi-Omics Analyses Based on Genes Associated with Oxidative Stress and Phospholipid Metabolism Revealed the Intrinsic Molecular Characteristics of Pancreatic Cancer

    The metabolic data of 35 pancreatic tumor samples, 34 para-carcinoma samples, and 31 normal pancreatic tissues were obtained from the previously published literature. Pan-cancer samples were obtained from The Cancer Genome Atlas.

    miR-33a-3p Regulates METTL3-Mediated AREG Stability and Alters EMT to Inhibit Pancreatic Cancer Invasion and Metastasis

    Experiment results supported the notion that amphoteric regulatory protein (AREG) was overexpressed in pancreatic cancer tissues and cell lines. Functionally, the deletion of AREG impeded pancreatic cancer cell proliferation, migration, and invasion.
