Anti⁃hyperlipidemia mechanism of Nelumbinis Folium via regulating aquaporins expression
Objective,2,To investigate the regulation and mechanism of Nelumbinis Folium on aquaporins (AQPs) and water metabolism in hyperlipidemia (HLP) model rats.,Methods,2,A hyperlipidemic SD rat model was established with high-fat diet feeding. The rats were randomly divided into normal group, model group, ezetimibe group and Nelumbinis Folium group, with 7 rats in each group. Rats in normal group and model group were given intragastric administration of pure water, and rats in other two groups were given intragastric administration of ezetimibe or Nelumbinis Folium water extract in respective doses, once a day for 6 consecutive weeks. Serum triacylglycerol (TG) samples were detected by automatic biochemical analyzer; Serum gastrin (GAS), motilin (MTL) and Na,+,-K,+,-ATPase levels were determined by ELISA; The mRNA expression of ,AQP3,, ,AQP8, and ,AQP9, in colon tissue were detected by RT-qPCR; and Hmatoxylin-Eosin (HE) staining and oil red O staining were applied to observe the pathological changes of liver tissues.,Results,2,Compared with the model group, Nelumbinis Folium group showed decreased serum TG and MTL levels, significantly increased GAS and Na,+,-K,+,-ATPase content, down-regulated mRNA expression of ,AQP8, and ,AQP9, in colon tissues, and significantly reduced lipid deposition in liver cells of HLP model rats.,Conclusion,2,Nelumbinis Folium has a regulatory effect on TG levels in HLP model rats, and the mechanism may be related to regulating the expression of aquaporins, improving the transportation and transformation function of the spleen and water metabolism.
