Abstract:
Objective To explore the effect of acteoside (one of the ingredients of Total Glycosides Extracted from Rehmannia capsules) on treatment of proteinuria and protection of podocytes.Methods In this study,puromycin nephropathy rat model was successfully established.After detecting the degree of proteinuria,the expression of podocyte injury markers and the degree of podocyte foot process fusion were investigated by electron microscope.In addition,puromycin treated podocyte injury model was also successfully established in vitro.Podocyte viability,migration,cytoskeleton and injury marker were detected.Results In vivo study showed that acteoside could effectively reduce proteinuria (P ＜ 0.05),restore the expression of podocyte injury markers such as nephrin and synaptopodin (all P ＜ 0.05),and alleviate the degree of podocyte foot process fusion.In vitro study showed that acteoside could effectively restored podocyte viability (P ＜ 0.05),reduce abnormal migration ability (P ＜ 0.05),protecte cytoskeleton and restore the expression of podocyte injury marker nephrin (P ＜ 0.05).Conclusions This study confirms that acteoside can reduce the degree of proteinuria in puromycin nephropathy rat model in vivo and alleviate the degree of podocyte injury in vitro as well as enrich the molecular mechanism of Total Glycosides Extracted from Rehmannia capsules in treatment of proteinuria.
