    Lysosomal Ca2+-Mediated TFEB Activation Modulates Mitophagy and Functional Adaptation of Pancreatic β-Cells to Metabolic Stress

    Scientists studied the role of lysosomal Ca2+ in transcription Factor EB (TFEB) activation by mitochondrial or metabolic stress and that of TFEB-mediated mitophagy in pancreatic β-cell function.

    TAZ Promotes PDX1-Mediated Insulinogenesis

    Transcriptional co-activator with PDZ-binding motif (TAZ) defect caused structural changes in the pancreas, particularly islet cell shrinkage, and decreased insulin production and β-cell markers expression, leading to hyperglycemia.
    [Cellular and Molecular Life Sciences]

    Abstract

    Increased Expression of Viral Sensor MDA5 in Pancreatic Islets and in Hormone-Negative Endocrine Cells in Recent Onset Type 1 Diabetic Donors

    The authors used multiplex immunofluorescence imaging analysis to characterize melanoma differentiation associated gene 5 (MDA5) expression and distribution in pancreatic tissues obtained from 22 organ donors.

    The Human AP-Endonuclease 1 (APE1) Is a DNA G-Quadruplex Structure Binding Protein and Regulates KRAS Expression in Pancreatic Ductal Adenocarcinoma Cells

    Scientists showed that APE1 (apurinic/apyrimidinic endonuclease 1), a multifunctional DNA repair enzyme, was a G-quadruplex (G4)-binding protein, and loss of APE1 abrogated the formation of stable G4 structures in cells.

    Hypoxia-Induced Long Noncoding RNA NR2F1-AS1 Maintains Pancreatic Cancer Proliferation, Migration, and Invasion by Activating the NR2F1/AKT/mTOR Axis

    The biological effects of nuclear receptor subfamily 2 group F member 1 antisense RNA 1 (NR2F1-AS1) and NR2F1 in pancreatic cancer were investigated by in vitro and in vivo experiments.

    UHMK1 Is a Novel Marker for Personalized Prediction of Pancreatic Cancer Prognosis

    U2AF homology motif kinase 1 (UHMK1) expression was enhanced in PDAC, and high UHMK1 expression correlated with tumor stage, and lower overall survival.
