Abstract:
ObjectiveTo observe the intervention of modified Sanrentang on the lipopolysaccharide-induced proliferation of rat glomerular mesangial cells， the phosphatidylinositol-3 kinase（PI3K）/protein kinase B（PKB/Akt）/nuclear factor kappa B（NF-κB） signaling pathway， and to investigate its mechanism in improving kidney inflammation in rats with immunoglobulin A nephropathy（IgAN）. MethodThe 18 rats were divided into 3 groups by serum pharmacology method： normal group， high-dose and low-dose （20.70，10.35 g·kg-1·d-1） groups with 6 rats in each group. Modified Sanrentang high- and low-dose groups were intragastric with the corresponding solution of modified Sanrentang， and normal group was intragastric with equal volume of distilled water. After 5 days of intragastric administration， blood samples were collected to prepare drug-containing serum. Rat mesangial （HBZY-1） were divided into five groups of normal group， LPS 10 mg·L-1 in the model group， benazepril（50 μmol·L-1）， modified Sanrentang high- and low-dose group. Preclude the use of methyl thiazolyl tetrazolium（MTT） method detect the proliferation activity of HBZY-1 cells， enzyme-linked immunosorbent assay（ELISA） was used to determine the content of each group type Ⅳ collagen（ColⅣ），Western blot and Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） were used to detect protein and mRNA expression levels of PI3K/Akt/NF-κB signaling pathway. ResultAs compared with the normal group， MTT assay showed that exposure to LPS significantly enhanced the proliferative activity， the ColⅣ was increased significantly of HBZY-1 cells（P<0.01）， p-Akt， p-p65 was increased significantly （P<0.01）. Compared with the model group， the proliferation and ColⅣ of rat chronic glomerulonephritis cells induced by LPS by inhibiting PI3K/Akt/NF-κB signaling pathway（P<0.01）， and the phosphorylation of Akt was significantly inhibited（P<0.01）， the expression levels of NF-κB p65 was reduced in modified Sanrentang high-dose group（P<0.01）. ConclusionModified Sanrentang could inhibit cell proliferation and the content of ColⅣ in rat mesangial cells induced by LPS， and its mechanism might be related to suppression of PI3K/Akt signaling pathway.
