    A Hormone Complex of FABP4 and Nucleoside Kinases Regulates Islet Function

    Researchers showed that hormonal FABP4 formed a functional hormone complex with adenosine kinase and nucleoside diphosphate kinase to regulate extracellular ATP and ADP levels.

    Cyanidin-3-Rutinoside Stimulated Insulin Secretion through Activation of L-type Voltage-Dependent Ca2+ Channels and the PLC-IP3 Pathway in Pancreatic β-Cells

    Scientists identified cyanidin-3-rutinoside’s (C3R) mechanisms of action in pancreatic β-cells. Rat INS-1 cells were used to elucidate the effects of C3R on insulin secretion, intracellular Ca2+ signaling, and gene expression.

    Intra-Islet Glucagon Confers β-Cell Glucose Competence for First-Phase Insulin Secretion and Favors GLP-1R Stimulation by Exogenous Glucagon

    Researchers reported that intra-islet glucagon secreted from α-cells signals through β-cell glucagon and GLP-1 receptors, thereby conferring to rat islets their competence to exhibit first phase glucose-stimulated insulin secretion.

    Smoothened (SMO) Regulates Insulin-Like Growth Factor 1 Receptor (IGF1R) Levels and Protein Kinase B (AKT) Localization and Signaling

    Investigators provided evidence that elevated levels of human SMO showed a strong correlation with elevated levels of insulin-like growth factor 1 receptor and reduced survival in diffuse large B cell lymphoma.

    Abstract

    β-Amyrin Ameliorates Diabetic Nephropathy in Mice and Regulates the miR-181b-5p/HMGB2 Axis in High Glucose-Stimulated HK-2 Cells

    HK-2 cell viability and apoptosis were detected by Cell Counting Kit-8 assay and flow cytometry analysis, respectively. β-amyrin was found to ameliorate kidney injury in diabetic nephropathy mice and suppressed inflammatory response as well as apoptosis of high glucose-stimulated HK-2 cells.

    Abstract

    The MK2/Hsp27 Axis Is a Major Survival Mechanism for Pancreatic Ductal Adenocarcinoma under Genotoxic Stress

    Scientists identified and characterized resistance mechanisms to a FIRINOX chemotherapy regimen because it was the most aggressive regimen currently used clinically for patients with PDAC.

    HDAC2 Facilitates Pancreatic Cancer Metastasis

    Using genetically defined models, researchers showed that histone deacetylase (HDAC2) was a cellular fitness factor that controls cell cycle in vitro and metastasis in vivo, particularly in undifferentiated, mesenchymal PDAC.

    SYT8 Promotes Pancreatic Cancer Progression via the TNNI2/ERRα/SIRT1 Signaling Pathway

    Synaptotagmin-8 (SYT8) is a membrane protein that regulates hormone secretion and neurotransmission, and its expression is positively regulated by the promoter of the insulin gene in pancreatic islet cells. The authors identified a previously unknown role of SYT8 in altering tumor characteristics in pancreatic cancer.

    MiR-199 Reverses the Resistance to Gemcitabine in Pancreatic Cancer by Suppressing Stemness through Regulating the Epithelial–Mesenchymal Transition

    Scientists investigated the function of miR-199 on gemcitabine-resistance in pancreatic cancer, as well as the underlying mechanism.

    Intra-Pancreatic Fat Deposition: Bringing Hidden Fat to the Fore

    Weight loss-induced decrease of intra-pancreatic fat is tightly associated with remission of type 2 diabetes mellitus and its re-deposition with recurrence of the disease.
