    Extracellular Vesicles from Pancreatic Cancer Stem Cells Lead an Intratumor Communication Network (EVNet) to Fuel Tumour Progression

    Researchers demonstrated that PDAC tumors established an organized communication network between subpopulations of cancer cells using extracellular vesicles called the EVNet.

    Grainyhead 1 Acts as a Drug-Inducible Conserved Transcriptional Regulator Linked to Insulin Signaling and Lifespan

    Scientists showed that increased expression of the transcription factor Grainyhead 1 promoted lifespan and pathogen resistance in Caenorhabditis elegans.

    Organization and Dynamics of the Cortical Complexes Controlling Insulin Secretion in β-Cells

    Researchers showed that insulin secretion sites also contained non-neuronal proteins LL5β and KANK1, which in migrating cells organized exocytotic machinery in the vicinity of integrin-based adhesions.

    Abstract

    LDB1-Mediated Transcriptional Complexes Are Sensitive to Islet Stress

    The authors hypothesized that LIM domain-binding protein 1 (LDB1) and/or islet-1 levels, like other transcriptional regulators, were sensitive to β-cell nutrient and cytokine stresses, likely contributing to β-cell (dys)function under various stimuli.

    ATP Is an Essential Autocrine Factor for Pancreatic β-Cell Signaling and Insulin Secretion

    Scientists monitored changes of the intracellular Ca2+ concentration as an immediate read-out for insulin secretion in live cell experiments.

    Progranulin Mediates Immune Evasion of Pancreatic Ductal Adenocarcinoma through Regulation of MHCI Expression

    Researchers characterized the function of tumor-derived progranulin in promoting immune evasion in primary PDAC.

    Analysis of the Glyco-Code in Pancreatic Ductal Adenocarcinoma Identifies Glycan-Mediated Immune Regulatory Circuits

    By analysing publicly available transcriptomic data of patient samples and cell lines, scientists identified two specific glycan profiles in PDAC that correlated with progression, clinical outcome and epithelial to mesenchymal transition status.

    Repeated Treatments of Capan-1 Cells with PARP1 and Chk1 Inhibitors Promote Drug Resistance, Migration and Invasion

    Poly(ADP-ribose) polymerase 1 (PARP1) and checkpoint kinase 1 (Chk1) inhibitors have been shown to be synergistic in different cancer models in relatively short time treatment modes. The synergistic cytotoxicity of their combinations in eight tumor cell lines was confirmed in a seven day exposure mode.

    Multimodal Evaluation of 19F-BPA Internalization in Pancreatic Cancer Cells for Boron Capture and Proton Therapy Potential Applications

    Researchers evaluated the in vitro internalization of the 19F-labelled p-boronophenylalanine (19F-BPA) in the human cancer pancreatic cell line for the potential application of boron neutron capture therapy and proton boron fusion therapy in pancreatic cancer.

    REVIEWS

    Inter-Organ Crosstalk in Pancreatic Islet Function and Pathology

    Scientists discuss recent advances in inter-organ communication from the metabolic, immune, and neural system to pancreatic islets, their biological implication in normal pancreas endocrine function, as well as their role in the adaptive responses of islet to nutrition-induced stress.
