This study aimed to develop a specific and sensitive method for the rapid detection of NF-κB activity in pancreatic tissue. Male Wistar rats were randomly divided into two groups: (1) 16 rats in the acute pancreatitis (AP) group received retrograde injection of 5% sodium taurocholate (STC) into the biliopancreatic duct, and (2) 16 rats in the Control group received saline. NF-κB activation in rat pancreatic acinar cells was assessed by flow cytometry (FCM). We found that the NF-κB activity in the AP group significantly increased at 1.5 h (29.80%±7.83), had a peak at 3 h (65.17%±13.22), and then decreased gradually to 12 h time point, close to the level after 1.5 h stimulation of STC. The NF-κB activity of the Control group did not significantly vary at different time points (P>0.05). FCM is a specific and sensitive assay for the rapid detection of NF-κB activity in pancreatic tissue.
本研究旨在开发一种用于快速检测胰腺组织中NF-κB活性的特异且灵敏的方法。雄性Wistar大鼠被随机分为两组:(1)急性胰腺炎(AP)组的16只大鼠接受逆行向胆胰管注射5%牛磺胆酸钠(STC),(2)对照组的16只大鼠接受生理盐水注射。通过流式细胞术(FCM)评估大鼠胰腺腺泡细胞中的NF-κB激活情况。我们发现,AP组中NF-κB活性在1.5小时时显著升高(29.80%±7.83),在3小时时达到峰值(65.17%±13.22),然后逐渐下降至12小时时间点,接近STC刺激1.5小时后的水平。对照组的NF-κB活性在不同时间点无显著变化(P>0.05)。流式细胞术是一种用于快速检测胰腺组织中NF-κB活性的特异且灵敏的检测方法。
