Wip1 Aggravates the Cerulein-Induced Cell Autophagy and Inflammatory Injury by Targeting STING/TBK1/IRF3 in Acute Pancreatitis

xlomafota.13 shared this article with you from Inoreader Wip1 Aggravates the Cerulein-Induced Cell Autophagy and Inflammatory Injury by Targeting STING/TBK1/IRF3 in Acute Pancreatitis Via Latest Results for Inflammation Abstract Acute pancreatitis (AP) is an inflammatory reaction of pancreatic tissue self-digestion, edema, hemorrhage, and even necrosis after the activation of pancreatic enzymes in the pancreas caused by a variety of etiologies. This study was aimed to explore the functions and mechanism of Wip1 in AP. Twenty male SD rats were randomly assigned into 2 groups (control group: saline treatment; AP group: cerulein treatment). And cerulein-treated AR42J cells were conducted as AP model in vitro. The levels of amylase were detected by using the Beckman biochemical analyzer. The levels of IFNβ and TNFα were analyzed by ELISA. The autophagosomes were observed by transmission electron microscopy. The Wip1-specific shRNAs were transfected to AR42J cells to silence the expression of Wip1. The levels of Wip1 were measured by qRT-PCR and Western blot. The levels of STING/TBK1/IRF3 and LC3 were measured by Western blot. The AP model was successfully constructed by cerulein a dministration. Wip1 was notably upregulated in AP models. Autophagy and STING pathway activation were involved in the development of AP. Wip1 inhibition counteracts the promotion effect on inflammatory response induced by cerulein in AR42J Cells. Wip1 inhibition inhibited the activity of the STING/TBK1/IRF3 and reduced LC3 levels in AP. This study preliminarily explored that Wip1 could regulate autophagy and participate in the development of AP through the STING/TBK1/IRF3 signaling pathway. View on the web Inoreader.
