    Exocrine Pancreas Regeneration Modifies Original Pancreas to Alleviate Diabetes in Mouse Models

    The authors showed that pancreas-derived mesenchymal stem cells were capable of regenerating exocrine pancreas when implanted into the kidney capsule of mice with streptozotocin–induced diabetes.

    Synaptotagmin-13 Orchestrates Pancreatic Endocrine Cell Egression and Islet Morphogenesis

    By internalizing a subset of plasma membrane proteins at the front domain, including α6β4 integrins, Syt13 modulated cell-matrix adhesion and allowed efficient endocrine cell egression.

    Adaptation to Chronic ER Stress Enforces Pancreatic β-Cell Plasticity

    Single cell RNA-sequencing analysis of islets from type 1 diabetes patients indicated severe deregulation of the chronic stress-adaptation program and revealed novel biomarkers of diabetes progression.

    Reduced Calcium Levels and Accumulation of Abnormal Insulin Granules in Stem Cell Models of HNF1A Deficiency

    Scientists demonstrated that HNF1A-deficient β-cells displayed impaired basal and glucose stimulated-insulin secretion, reduced intracellular calcium levels in association with a reduction in CACNA1A expression, and accumulation of abnormal insulin granules in association with SYT13 down-regulation.

    Imeglimin Exerts Favorable Effects on Pancreatic β-Cells by Improving Morphology in Mitochondria and Increasing the Number of Insulin Granules

    Investigators reported that single-dose administration of imeglimin significantly augmented insulin secretion in response to glucose from islets isolated from non-diabetic mice.

    CD9 Mediates the Uptake of Extracellular Vesicles From Cancer-Associated Fibroblasts That Promote Pancreatic Cancer Cell Aggressiveness

    The authors demonstrated that blocking either CD9 or p38 MAPK signaling impaired CD9+ annexin A6 extracellular vesicle–induced cell migration and epithelial-to-mesenchymal transition in PDAC cells.

    Gemcitabine Resistance of Pancreatic Cancer Cells Is Mediated by IGF1R Dependent Upregulation of CD44 Expression and Isoform Switching

    CD44 promoter activity and its interactive EMT-related transcription factors were evaluated by luciferase reporter assay and chromatin immunoprecipitation assay.

    CASC9 Potentiates Gemcitabine Resistance in Pancreatic Cancer by Reciprocally Activating NRF2 and the NF-ÎşB Signaling Pathway

    Researchers discovered that gemcitabine upregulated the expression of cancer susceptibility candidate 9 (CASC9) in a dose-dependent manner, partially via induction of reactive oxygen species, whereas inhibition of CASC9 expression enhanced gemcitabine-induced oxidative stress and apoptosis in pancreatic cancer cells.

    Abstract

    ZNF655 Accelerates Progression of Pancreatic Cancer by Promoting the Binding of E2F1 and CDK1

    Scientists demonstrated that Zinc finger protein 655 (ZNF655) knockdown inhibited the biological progression of pancreatic cancer cells, which was characterized by weaken proliferation, enhanced apoptosis, arrested cell cycle in G2, impeded migration, and suppressed tumor growth.

    Synthetic Oleanane Triterpenoid Derivative CDDO-Me Disrupts Cellular Bioenergetics To Suppress Pancreatic Ductal Adenocarcinoma via Targeting SLC1A5

    The authors verified that methyl-2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oate (CDDO-Me) downregulated glutamine transporter SLC1A5, resulting in excessive reactive oxygen species levels that suppressed tumor growth.

    Abstract

    An Oleanolic Acid Derivative, K73-03, Inhibits Pancreatic Cancer Cells Proliferation In Vitro and In Vivo via Blocking EGFR/Akt Pathway

    Investigators demonstrated that K73-03 effectively inhibited the cell proliferation of pancreatic cells, and induced apoptosis and autophagy of ASPC-1 cells in a dose-dependent manner.
