6Norisoboldine, a natural aryl hydrocarbon receptor agonist, alleviates TNBS-induced colitis in mice, by inhibiting the activation of NLRP3 inflammasome显示文摘Although the etiology of inflammatory bowel disease is still uncertain, increasing evidence indicates that the excessive activation of NLRP3 inflammasome plays a major role. Norisoboldine(NOR), an alkaloid isolated from Radix Linderae, has previously been demonstrated to inhibit inflammation and IL-1β production. The present study was to examine the effect of NOR on colitis and the underlying mechanism related to NLRP3 inflammasome activation. Our results showed that NOR alleviated colitis symptom in mice induced by 2, 4, 6-trinitrobenzene sulfonic acid(TNBS). Moreover, it significantly reduced expressions of cleaved IL-1β, NLRP3 and cleaved Caspase-1 but not ASC in colons of mice. In THP-1 cells, NOR suppressed the expressions of NLRP3, cleaved Caspase-1 and cleaved IL-1β but not ASC induced by lipopolysaccharide(LPS) and adenosine triphosphate(ATP). Furthermore, NOR could activate aryl hydrocarbon receptor(AhR) in THP-1 cells, inducing CYP1 A1 mR NA expression, and promoting dissociation of Ah R/HSP90 complexes, association of AhR and ARNT, Ah R nuclear translocation, XRE reporter activity and binding activity of Ah R/ARNT/XRE. Both siA hR and α-naphthoflavone(α-NF) markedly diminished the inhibition of NOR on NLRP3 inflammasome activation. In addition, NOR elevated Nrf2 level and reduced ROS level in LPS-and ATP-stimulated THP-1 cells, which was reversed by either si AhR or α-NF treatment. Finally, correlations between activation of AhR and attenuation of colitis, inhibition of NLRP3 inflammasome activation and up-regulation of Nrf2 level in colons were validated in mice with TNBS-induced colitis. Taken together, NOR ameliorated TNBS-induced colitis in mice through inhibiting NLRP3 inflammasome activation via regulating AhR/Nrf2/ROS signaling pathway.LV Qi WANG Kai QIAO Si-Miao DAI Yue WEI Zhi-Feng 2018Chinese Journal of Natural Medicines2018,16,3:8

11Longitudinal analysis of inflammation and microbiota dynamics in a model of mild chronic dextran sulfate sodium-induced colitis in mice显示文摘AIM:To characterize longitudinally the inflammation and the gut microbiota dynamics in a mouse model of dextran sulfate sodium(DSS)-induced colitis.METHODS:In animal models,the most common method used to trigger colitis is based on the oral administration of the sulfated polysaccharides DSS.The murine DSS colitis model has been widely adopted to induce severe acute,chronic or semi-chronic colitis,and has been validated as an important model for the translation of mice data to human inflammatory bowel disease(IBD).However,it is now clear that models characterized by mild intestinal damage are more accurate for studying the effects of therapeutic agents.For this reason,we have developed a murine model of mild colitis to study longitudinally the inflammation and microbiota dynamics during the intestinal repair processes,and to obtain data suitable to support the recovery of gut microbiota-host homeostasis.RESULTS:All plasma cytokines evaluated,except IL-17,began to increase(P<0.05),after 7 d of DSS administration.IL-17 only began to increase 4 d after DSS withdrawal.IL-1βand IL-17 continue to increase during the recovery phase,even when clinical signs of colitis had disappeared.IL-6,IL-10 and IFN-γreached their maxima 4 d after DSS withdrawal and decreased during the late recovery phase.TNFαreached a peak(a three-fold increase,P<0.05),after which it slightly decreased,only to increase again close to the end of the recovery phase.DSS administration induced profound and rapid changes in the mice gut microbiota.After 3 d of DSS administration,we observed a major reduction in Bacteroidetes/Prevotella and a corresponding increase in Bacillaceae,with respect to control mice.In particular,Bacteroidetes/Prevotella decreased from a relative abundance of 59.42%-33.05%,while Bacillaceae showed a concomitant increase from 2.77%to 10.52%.Gut microbiota rapidly shifted toward a healthy profile during the recovery phase and returned normal 4 d after DSS withdrawal.Cyclooxygenase 2 expression started to increase 4 d after DSS withdrawal(P<0.05),when dysbiosis had recovered,and continued to increase during the recovery phase.Taken together,these data indicated that a chronic phase of intestinal inflammation,characterized by the absence of dysbiosis,could be obtained in mice using a single DSS cycle.CONCLUSION:Dysbiosis contributes to the local and systemic inflammation that occurs in the DSS model of colitis;however,chronic bowel inflammation is maintained even after recovery from dysbiosis.Luigia De Fazio Elena Cavazza Enzo Spisni Antonio Strillacci Manuela Centanni Marco Candela Chiara Praticò Massimo Campieri Chiara Ricci Maria Chiara Valerii 2014World Journal of Gastroenterology2014,20,8:1
12重组KGF-2突变体对TNBS诱导的复发性大鼠炎性肠病模型治疗作用的研究显示文摘目的制备复发性大鼠炎性肠病模型,评价重组KGF-2突变体(STEA)给药对2,4,6-三硝基苯磺酸(TNBS)诱导的复发性大鼠炎性肠病模型的治疗效果。方法利用2%的TNBS(100mg/kg)对雄性Wistar大鼠进行灌肠,3周后,再次利用TNBS(10毫克/只)处理这些大鼠。于再次灌肠当天,治疗组的大鼠腹腔注射3mg/kg STEA,模型对照组和正常组注射等量的PB缓冲液,每天1次,连续7天。对各组大鼠的生存状态、血清中IL-6和IL-1β的表达水平、以及结肠组织病理变化等情况进行观察和分析。结果利用TNBS二次致敏的方法,成功制备了复发性大鼠炎性肠病模型。STEA给药能显著降低模型大鼠血清中IL-6和IL-1β的表达水平,提高大鼠的存活率,促进受损结肠黏膜的修复。结论 STEA对TNBS诱导的复发性大鼠的结肠损伤具有治疗作用。王金凤 王园园 付文亮 蔡欣 邹民吉 邢微微 陈惠华 徐东刚 2013医学研究杂志2013,42,7:0
13Nilotinib-mediated mucosal healing in a rat model of colitis显示文摘AIM:To investigate the effects of nilotinib in a rat model of trinitrobenzene sulfonic acid(TNBS)-induced colitis.METHODS:Twenty-one Wistar albino female rats obtained from Dokuz Eylul University Department of Laboratory Animal Science were categorized into a control(n=7),TNBS(n=7)and nilotinib group(n=7).Saline was administered orally for 14 d to the control and the TNBS group.The TNBS group received rectal TNBS on the first day while saline was administered to the control group.The nilotinib group received 20mg/kg nilotinib for 14 d in 2 divided doses,starting the same day as TNBS administration.For 14 d,the rats were fed a standard diet,and their weights were recorded daily.After sacrifice,colon tissue samples from each group were scored for macroscopic and microscopic pathology.Apoptotic indices were determined by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling method.Platelet-derived growth factor receptor(PDGFR)alpha and beta levels were assessed through immunohistochemistry staining scores and compared among the groups.Tissue and serum tumor necrosis factor(TNF)alpha levels were determined by enzyme-linked immunosorbent assay.RESULTS:Between days 1 and 14,the nilotinib group rats lost significantly less weight than the TNBS group rats(-0.7 g vs-14.0 g,P=0.047).The difference in weight between the control and nilotinib groups was also statistically significant(+8.3 gvs-0.7 g,P=0.031).From day 7 to day 14,the weight differences of the control group vs the TNBS group,the TNBS group vs the nilotinib group,and the control group vs the nilotinib group were all statistically significant(+8.0 g vs-11.1 g,P=0.007;-11.1 g vs+2.9 g,P=0.015;+8.0g vs+2.9 g,P=0.042,respectively).Macroscopic and microscopic scores were significantly lower in the nilotinib group than in the TNBS group(0.00±0.00 vs 1.43±0.65,P=0.009;2.86±0.55 vs 7.71±1.48,P=0.030,respectively).However,these scores were similar between the nilotinib and control groups.While no significant difference for the nilotinib vs control groups could be determined for PDGFR alpha and beta scores,PDGFR alpha and beta scores were lower in the nilotinib group than in the TNBS group.Furthermore,the TNF alpha levels in the serum,tissue and apoptosis scores were similar between the nilotinib and TNBS groups.CONCLUSION:Nilotinib prevents weight loss,facilitates mucosal healing by improving the pathological scores without introducing variation into the apoptotic scores or TNF alpha levels.Pinar Ataca Mujde Soyturk Meral Karaman Mehtat Unlu Ozgul Sagol Gozde Dervis Hakim Osman Yilmaz 2013World Journal of Gastroenterology2013,19,37:0
