Quercetin inhibits caerulein-induced acute pancreatitis through regulating miR-216b by targeting MAP2K6 and NEAT1.
Acute pancreatitis (AP) is a common acute abdominal disease with high mortality and mortality rates. Increasing evidences clarified that Traditional Chinese Medicine (TCM) adjuvant therapy for AP can be used and it gives a positive effect. Quercetin (3,3',4',5,7-pentahydroxyflavone, QE) is a type of flavone compound with positive effect on cancer and inflammation prevention. ⋯ Because of the target, NEAT1, miR-216b, and MAP2K6 formed a competitive endogenous RNA (ceRNA) network. Besides direct target mediated by QE, it also decreased TNF-α which down-regulated TRAF2 and MAP3K5 located on upstream of p38/MAPK signaling and formed a feedback loop. In conclusion, QE has a protective effect on AP through inhibiting p38/MAPK signaling pathway by up-regulating miR-216b and suppressing TNF-α.
