    NR4A1 Enhances MKP7 Expression to Diminish JNK Activation Induced by ROS or ER-Stress in Pancreatic β Cells for Surviving

    To search other possible mechanisms, scientists found the mRNA level and protein level of MKP7 were dramatically reduced in pancreatic β cells in the islets from NR4A1 knockout mice compared with that from wild type mice.

    Abnormal Expression of microRNA-296-3p in Type 2 Diabetes Patients and its Role in Pancreatic β-Cells Function by Targeting Tensin Homolog Deleted on Chromosome Ten

    Min6 cells were induced by 5 mg/dl uric acid and the cell proliferation, apoptosis, and insulin release were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry and glucose-stimulated insulin secretion, respectively.

    T Cells Armed with C-X-C Chemokine Receptor Type 6 Enhance Adoptive Cell Therapy for Pancreatic Tumours

    Researchers showed that forced expression of C-X-C chemokine receptor type 6 in antigen-specific T cells enhanced the recognition and lysis of pancreatic cancer cells and the efficacy of adoptive cell therapy for pancreatic cancer.

    Valosin-Containing Protein Stabilizes Mutant p53 to Promote Pancreatic Cancer Growth

    The authors identified valosin-containing protein as a regulator of p53-R273H by conducting immunoprecipitation-tandem mass spectrometry analysis. Valosin-containing protein bound p53-R273H at its DNA binding domain.

    Exosomal Linc-ROR Mediates Crosstalk between Cancer Cells and Adipocytes to Promote Tumor Growth in Pancreatic Cancer

    The effects of conditioned medium collected from dedifferentiated adipocytes on pancreatic cancer cell proliferation, motility, metastasis and epithelial-mesenchymal transition were evaluated by western blot analysis, colony forming, real-time cell analysis, 5-ethynyl-2’-deoxyuridine, immunofluorescence, Transwell and wound healing assays in vitro.

    miR-194-5p Down-Regulates Tumor Cell PD-L1 Expression and Promotes Anti-tumor Immunity in Pancreatic Cancer

    Investigators found that high expression of miR-194-5p in human pancreatic cancer patients was associated with a better survival rate, while increased expression of programmed cell death ligand 1 in human pancreatic cancer patients was associated with a worse survival rate.
