高尿酸血症小鼠模型构建及其对肠屏障损伤的影响
Establishment of a mouse model of hyperuricemia with intestinal barrier injury
摘要
Abstract
Objective To establish a stable mouse model of intestinal barrier injury induced by hyperuricemia.Methods The mice were given different concentrations of adenine(Ade)and potassium oxazinate(PO)by gavage,and serum uric acid,urea nitrogen,creatinine,and intestinal permeability were measured on days 3,7,14,and 21.The expression levels of tight junction proteins Occludin,ZO-1,and Claudin-1 in the jejunum,ileum,and colon were measured.Results The high concentrations of Ade and PO induced a significant increase in uric acid(F=25.453-518.039,P<0.01)and a significant reduction in body weight(F=6.900-43.724,P<0.05).Administration of 50 mg/kg Ade and 125 mg/kg PO by gavage for 7 consecutive days induced a significant increase in uric acid(P<0.05),which continued to rise until day 21(P<0.05),and there was also a significant increase in intestinal permeability(F=28.563-185.808,P<0.05),which was positively correlated with the level of uric acid(r=0.876 9,P<0.05).Compared with normal mice,the mice with hyperuricemia had significant reductions in the expression levels of Occludin and ZO-1 in the ileum and the colon(t=3.164,3.678;P<0.05),as well as a significant reduction in the expression level of Clau-din-1 in the jejunum(t=2.670,P<0.05).Conclusion Administration of 50 mg/kg Ade and 125 mg/kg PO by gavage for 7 consecutive days can establish a mouse model of hyperuricemia with intestinal barrier injury.关键词
