远志等中药对脑淀粉样血管病相关蛋白胱抑素聚集的影响
Effect of Polygala on the aggregation of cerebral amyloid disease-related protein cystatin
摘要
Abstract
Objective The primary aim of this study is to investigate the effect of traditional Chinese medicine on the aggregation of Human cystatin C,a kind of cerebral amyloid disease-related protein. Methods With the addition of suboptimal concentrations of Chinese medicine to the induction medium of cystatin yeast expression system, the effects of traditional Chinese medicine on cystatin is determined both in vilro and in vivo using SDS-PAGE and western blotting. Results Extracellular experiments demonstrated that Polygala significantly represses the aggregation of cystatin. The concentration of Polygala has a positive relationship to its inhibitory effect on cystatin aggregation at the concentration below 500 μg/mL. Intracellular experiments showed that Polygala has no effect on cystatin aggregation in vivo. Conclusion Polygala has an obvious inhibitory effect on the aggregation of secreted cystatin.关键词
