Xanthine Oxidase: A Longstanding Target in Acute Pancreatitis with New Ways

Acute pancreatitis (AP) is a potentially fatal organ disease that is widespread globally. Although significant progress has been made in the previous decade, the study of mechanisms and therapeutic strategies is still far from being completed. Xanthine oxidase (XO) is an enzyme that generating urate and also responsible to produce reactive oxygen species (ROS). Considerable clinical and mechanical research has been conducted over many decades to explore the function of XO in AP and its promising therapeutic applications. Unquestionably, XO is a key part of starting and progressing AP by ROS production. Not fully known, though, are XO's many other functions besides ROS resource in both local and global processes, such as its role in cellular signaling or metabolism regulation. This review seeks to summarize the function of XO in AP pathophysiology by analyzing the inherent biological and chemical properties of XO, and lastly provide fresh concepts for future research.
