    The Anna Karenina Model of β Cell Maturation in Development and Their Dedifferentiation in Type I and Type II Diabetes

    Researchers constructed a multidimensional map of β cell transcriptional trajectories during the normal course of β cell postnatal development and during their dedifferentiation in models of both type I diabetes and type II diabetes.

    Long-RNA Sequencing and Ribosome Profiling of Inflamed Beta-Cells Reveal an Extensive Translatome Landscape

    Using a transcriptome-wide profiling approach to map translation initiation start sites in human beta-cells under standard and inflammatory conditions, the authors identified a completely new set of polypeptides derived from non-canonical start sites and translation initiation within lncRNA.

    Abstract

    Sulfiredoxin-1 Attenuates Injury and Inflammation in Acute Pancreatitis through the ROS/ER Stress/Cathepsin B Axis

    The pancreas was analyzed by histology, immunochemistry staining, and TUNEL assays, and the expression of certain proteins and RNAs, cytokine levels, trypsin activity, and reactive oxygen species (ROS) levels were determined.

    Inhibition of Discoidin Domain Receptors by Imatinib Prevented Pancreatic Fibrosis Demonstrated in Experimental Chronic Pancreatitis Model

    Chronic pancreatitis (CP) is a fibro-inflammatory disease in which recurrent pancreatic inflammation leads to pancreatic fibrosis. Scientists investigated the role of discoidin domain receptors in CP.

    Hemocompatible L-Type Amino Acid Transporter 1 (LAT1)-Utilizing Prodrugs of Perforin Inhibitors Can Accumulate Into the Pancreas and Alleviate Inflammation-Induced Apoptosis

    The effects of prodrug 1 were studied in lipopolysaccharide-induced in vitro and in vivo apoptosis and pancreatitis models by determining the cellular apoptotic levels with human umbilical vein endothelial cells and pancreatic caspase-3/-7 activity in mice.

    Nicotine Facilitates Pancreatic Fibrosis by Promoting Activation of Pancreatic Stellate Cells via α7nAChR-Mediated JAK2/STAT3 Signaling Pathway in Rats

    Investigators suggested that nicotine has the potential to facilitate pancreatic fibrosis in chronic pancreatitis. They analyzed the function and mechanism of nicotine on pancreatic stellate cells and pancreatic fibrosis in rats.

    Abstract

    Vaccinia-Related Kinase 2 Drives Pancreatic Cancer Progression by Protecting Plk1 from Chfr-Mediated Degradation

    Scientists presented evidence that polo-like kinase 1 (Plk1) was a novel substrate of vaccinia-related kinase 2, a serine-threonine kinase that was highly expressed and predicted poor prognosis in pancreatic cancer.
