[Effects of the Saponins from Panax japonicus on Intestinal Epithelial Tight Junction Proteins in Aging Rats].
Objective: To investigate the moderating effects of total saponins of Panax japonicus on intestinal epithelial tight junction proteins in aging rats,and to explore the potential mechanism.
Methods: SD rats were divided into adult group( 6 months),old model group( 24 months),and different doses( 10,30 and 60 mg / kg) of total saponins of Panax japonicus treatment groups. Levels of tight junction proteins( Occludin and ZO-1),anti-oxidative pathway proteins( Nrf2、HO-1 and NQO-1),mitochondrial biogenesis related proteins( Sirt1 and PGC-1α) and p-AMPK in the ileum were determined by immunohistochemistry staining.
Results: Compared with adult group,the expressions of Occludin,ZO-1,Nrf2,HO-1,NQO-1,Sirt1 and PGC-1α of aging rats were obviously decreased( P < 0. 01),and p-AMPK was inhibited in the ileum of aging rats. Compared with aging model rats,total saponins of Panax japonicus increased the expressions of Occludin,ZO-1,Nrf2,HO-1,NQO-1,Sirt1 and PGC-1α( P < 0. 05 or P < 0. 01),and activated p-AMPK in the ileum of aging rats.
Conclusion: The decreased level of intestinal tight junction proteins in the ileum of aging rats may be related to oxidative stress. Total saponins of Panax japonicus can up-regulate the level of intestinal tight junction proteins to improve the intestinal mucosal barrier dysfunction in the ileum of aging rat via reducing the levels of oxidative stress.
