    TET1 Downregulates Epithelial-Mesenchymal Transition and Chemoresistance in PDAC by Demethylating CHL1 to Inhibit the Hedgehog Signaling Pathway

    In vitro and in vivo functional studies performed by silencing or overexpressing TET1 suggested that TET1 was able to suppress epithelial-mesenchymal transition and sensitize pancreatic ductal adenocarcinoma cells to 5FU and gemcitabine. RNA-seq, whole genome bisulfite sequencing and ChIP-seq were used to explore the TET1-associated pathway.

    Lactate Activation of α-Cell KATP Channels Inhibits Glucagon Secretion by Hyperpolarizing the Membrane Potential and Reducing Ca2+ Entry

    Mouse and human islets were used in combination with confocal microscopy, electrophysiology, glucagon immunoassays, and fluorescent thallium flux assays to assess α-cell Ca2+ handling, Vm, KATP currents, and GCG secretion.

    IL-17F Induces Inflammation, Dysfunction and Cell Death in Mouse Islets

    IL-17F possessed similar pathogenic activities to IL-17A in mouse β-cell lines and islets and was likely to be a type 17 associated pathogenic factor in type 1 diabetes.

    GINS2 Promotes EMT in Pancreatic Cancer via Specifically Stimulating ERK/MAPK Signaling

    Investigators found that overexpression of Go-Ichi-Ni-San 2 (GINS2) contributed to advanced clinical stage of pancreatic cancer and promoted epithelial–mesenchymal-transition in vitro and in vivo via specifically activating the ERK/MAPK signal pathway.

    DGAT1 Inhibitors Protect Pancreatic β-Cells from Palmitic Acid-Induced Apoptosis

    Researchers evaluated the potential beneficial effects of DGAT1 inhibitors on pancreatic β-cells, and further verified their antidiabetic effects in db/db mice.

    Lentiviral Gene Therapy Vectors Encoding VIP Suppressed Diabetes-Related Inflammation and Augmented Pancreatic Beta-Cell Proliferation

    The therapeutic efficacy of LentiVIP was tested in a multiple low-dose STZ-induced animal model of type 1 diabetes. LentiVIP delivery into diabetic animals reduced hyperglycemia, improved glucose tolerance, and prevented weight loss.

    Abstract

    Metformin Inhibits Pancreatic Cancer Metastasis Caused by SMAD4 Deficiency and Consequent HNF4G Upregulation

    The authors found that metformin suppressed HNF4G activity via AMPK-mediated phosphorylation-coupled ubiquitination degradation and inhibited in vitro invasion and in vivo metastasis of pancreatic ductal adenocarcinoma cells with SMAD4 deficiency.

    Hotspot Mutant p53-R273H Inhibits KLF6 Expression to Promote Cell Migration and Tumor Metastasis

    Researchers demonstrated that hotspot mutant p53, p53-R273H, promoted cell scattering growth and migration via inhibiting the expression of Krupple-like factor 6 (KLF6), a Zinc finger transcription factor and a documented tumor suppressor.

    Mucins in Pancreatic Cancer: A Well‐Established but Promising Family for Diagnosis, Prognosis and Therapy

    The authors discuss the important roles of mucins that lead to the lethality of pancreatic adenocarcinoma, particularly MUC1, MUC4, MUC5AC and MUC16 in disease progression, and present a comprehensive analysis of the clinical application of mucins and their promising roles in cancer treatment.
