    Basal-Like and Classical Cells Coexist in Pancreatic Cancer Revealed by Single-Cell Analysis on Biopsy-Derived Pancreatic Cancer Organoids from the Classical Subtype

    The authors performed single‐cell transcriptomic analyses using combinational barcoding exclusively on epithelial cells from six different classical pancreatic ductal adenocarcinoma patients obtained by Endoscopic Ultrasound with Fine Needle Aspiration.

    Mitomycin C Treatment Improves Pancreatic Islet Graft Longevity in Intraportal Islet Transplantation by Suppressing Proinflammatory Response

    Researchers present a simple approach for islet preconditioning that uses the antibiotic mitomycin C, which has antitumor activity, to reduce islet immunogenicity and prevent proinflammatory events in an intraportal islet transplantation model.

    Tectorigenin Enhances PDX1 Expression and Protects Pancreatic β-Cells by Activating ERK and Reducing ER Stress

    Investigators found that tectorigenin could suppress induced apoptosis and improved the viability of β-cells under glucotoxicity and lipotoxicity by activation of ERK and reduction of reactive oxygen species and endoplasmic reticulum stress.

    Abstract

    Prognostic Impact of CD73 Expression and Its Relationship to PD-L1 in Patients with Radically Treated Pancreatic Cancer

    Tissue microarray blocks were constructed and stained immunohistochemically using CD73 antibody. Staining intensity and numbers of stained tumor cells, inflammatory cells, stroma, and blood vessels were assessed.

    The Identification of Candidate Effective Combination Regimens for Pancreatic Cancer Using the Histoculture Drug Response Assay

    Scientists identified effective combination chemotherapy for pancreatic cancer using pancreatic cancer surgical specimens in the histoculture drug response assay based on 3D culture of tumor fragments, which maintained nature tumor histology in vitro.

    UAE1 Inhibition Mediates the Unfolded Protein Response, DNA Damage and Caspase-Dependent Cell Death in Pancreatic Cancer

    Inhibition of ubiquitin activating enzyme 1 (UAE1) activity in response to TAK-243 led to an accumulation of misfolded proteins within the endoplasmic reticulum (ER), thereby aggravating ER stress, leading to DNA damage and arrest of cells in the G2/M phase of the cell cycle.

    The USP22 Promotes the Growth of Cancer Cells through the DYRK1A in Pancreatic Ductal Adenocarcinoma

    Scientists report that USP22 promoted the growth of pancreatic ductal adenocarcinoma cells by promoting the expression of dual-specificity tyrosine regulated kinase 1A.

    The Role of Genetic Polymorphism within PD-L1 Gene in Cancer

    The expression of PD-L1 in tumors has been described in many histological types of cancer: melanoma, lung cancer, breast and ovarian, pancreatic and esophagus adenocarcinoma, kidney tumors and bladder cancers as well as in hematopoietic malignancies.

    ‘Ethically Troubling.’ University Reopening Plans Put Professors, Students on Edge

    Come August, hundreds of universities across the United States are poised to reopen their campuses with a mix of online and in-person courses. Only a handful are aiming for an entirely online semester. But as the machinery of higher education cranks back into action, faculty, staff, and students are voicing concerns that, with COVID-19 cases surging in many parts of the country, employees are being forced to put their health—and the health of others—at unnecessary risk.

    The Career Cost of COVID-19 to Female Researchers, and How Science Should Respond

    Early data on the effects of the coronavirus pandemic on scientific-publishing output suggest that female researchers, particularly those at early-career stages, are the hardest hit. Submissions to preprint servers, such as arXiv, rose more quickly for male authors than for female authors as nations adopted social-isolation measures.
