ABSTRACT
Objective:To investigate the effect of Astragalus polysaccharides on apoptosis,transdifferentiation and ROS content in renal tubular epithelial cells of diabetic nephropathy.Methods:HK-2 cells were divided into low glucose group,high glucose group and astragalus polysaccharide+high glucose group,cell proliferation was detected by CCK-8 assay after 48 h;cell apoptosis and ROS content was detected by flow cytometry;the expression of E-cadherin,α-SMA,STAT1,STAT3,p-STAT1,p-STAT3 protein were detected by Western blot.Results:The survival rate of cells in high glucose group was significantly lower than low sugar group (P<0.01),cell apoptosis rate,ROS content and E-cadherin,α-SMA,p-STAT1 and p-STAT3 protein expression was significantly higher than low sugar group (P<0.01),the cell survival rate in high glucose+astragalus polysaccharide group was significantly higher than high glucose group,cell apoptosis rate,ROS content and E-cadherin,α-SMA,p-STAT1 and p-STAT3 protein expression was significantly lower than high glucose group (P<0.01).Conclusion:Astragalus polysaccharides can promote the proliferation of renal tubular epithelial cells induced by high glucose,inhibit apoptosis and transdifferentiation,and the mechanism is related to down regulation of JAK/STAT signaling pathway.
