Unveiling the Emerging Role of Xanthine Oxidase in Acute Pancreatitis: Beyond Reactive Oxygen Species by Chenxia Han, Yaling Wu, Juan Rong, Qing Xia, Dan Du

“…Xanthine oxidase (XO) is an enzyme that catalyzes hypoxanthine and xanthine to produce urate and is accompanied by the generation of reactive oxygen species (ROS) in purine catabolism. Considerable preclinical and clinical studies have been conducted over many decades to investigate the role of XO in the pathogenesis of AP and its potential targeting therapeutic value. …”
