Emerging evidence suggests that NLRP3 inflammasome provides a link between colitis-associated colorectal cancer and inflammatory bowel diseases. Autophagy is induced in macrophages by AMPK activation and regulates NLRP3 inflammasome to maintain intracellular homeostasis. Here we report that a small-molecule AMPK activator (GL-V9) exerts potent anti-inflammatory effects on macrophages and , which trigger autophagy to degraded NLRP3 inflammasome. Treatment with GL-V9 protected against colitis and tumorigenesis in colitis-associated colorectal cancer. This suggests that GL-V9 may be an interesting candidate for clinical evaluation in the treatment of colitis-associated colorectal cancer.
新出现的证据表明,NLRP3炎性小体在结肠炎相关的结直肠癌和炎症性肠病之间建立了联系。自噬由AMPK激活在巨噬细胞中诱导产生,并调节NLRP3炎性小体以维持细胞内稳态。在此,我们报告一种小分子AMPK激活剂(GL-V9)对巨噬细胞具有强大的抗炎作用,巨噬细胞触发自噬以降解NLRP3炎性小体。用GL-V9治疗可预防结肠炎相关结直肠癌中的结肠炎和肿瘤发生。这表明GL-V9可能是治疗结肠炎相关结直肠癌临床评估中一个有吸引力的候选药物。
