    Abstract

    Protection
    of β-Pancreatic Cells from Dysfunctionality of Insulin Using Vitexin by Apoptosis of INS-1 Cells

    The authors explored the possible beneficial effects of vitexin on high glucose-induced cytotoxicity in pancreatic β-cells. The INS-1 pancreatic β-cell line was used in this study.

    IDO1-Dependent Tryptophan Metabolism Is Source of One-Carbon Units for Pancreatic Cancer and Stellate Cells

    Using in vitro and in vivo pancreatic cancer models, scientists showed that IDO1 expression was highly context dependent, influenced by attachment-independent growth and the canonical activator IFNγ.

    Schlafen 5 as a Novel Therapeutic Target in Pancreatic Ductal Adenocarcinoma

    Investigators provided evidence that a member of the human Schlafen (SLFN) family of proteins, SLFN5, is overexpressed in human PDAC. Targeted deletion of SLFN5 resulted in decreased PDAC cell proliferation and suppressed PDAC tumorigenesis in in vivo PDAC models.

    NR5A2
    Transcriptional Activation by BRD4 Promotes Pancreatic Cancer Progression by Upregulating GDF15

    Scientists demonstrated that NR5A2 acted as a negative prognostic biomarker in PDAC. NR5A2 silencing inhibited the proliferation and migration abilities of pancreatic cancer cells in vitro and in vivo.
