Abstract:
AIM:To explore the potential of Huangqi sanqi mixture(AP)in improving renal fi-brosis by performing transcriptome sequencing of the kidneys of the unilateral ureteral ligation mouse group and the Huangqi sanqi mixture inter-vention group,and using bioinformatics to verify the signitficantly different lncRNAs mechanism.METHODS:Twenty-four C57 mice were divided in-to sham operation group,renal fibrosis group,Huangqi sanqi mixture intervention group(3.944 g/kg)and irbesartan positive control intervention group,with 6 mice in each group.A mouse model of renal fibrosis was established by unilateral ure-teral ligation(UUO).The animals were given intra-gastric administration after operation,and the ani-mals were sacrificed and the specimens were col-lected after seven consecutive days of administra-tion.The changes of Huangqi sanqi mixture on re-nal fibrosis pathological damage were analyzed by HE and Masson staining,and the protein levels of Fn and α-SMA in renal tissue of each group were detected by Western blot and immunohistochemis-try to evaluate the alleviating effect of Huangqi san-qi mixture on renal fibrosis.Subsequently,lncRNA expression information was obtained by transcrip-tome sequencing,and Quantitative Real-time PCR(qPCR)was performed after data quality,GO en-richment and differential lncRNA were analyzed.According to the differential lncRNA and target analysis results obtained by sequencing,lncRNA Gm51500/Adam12 was overexpressed in vitro,and its mechanism in the protection of renal fibrosis by Huangqi sanqi mixture was studied by immunohis-tochemistry,immunofluorescence staining and qP-CR verification.RESULTS:Compared with the mod-el group,the renal fibrosis of the mice in the Huangqi sanqi mixture intervention group was sig-nificantly reduced,and the protein levels of α-SMA and Fn and the expression of lncRNA in the renal tis-sue were significantly down-regulated(P＜0.000 1).Three lncRNAs were screened and verified to in-crease in the model group and significantly de-crease after AP intervention,namely lncRNA Gm29994,Gm51500 and Gm35391.Target analysis showed that lncRNA Gm51500 had the most signifi-cant relationship with Adam12.The results of ani-mal experiments showed that Adam12 was highly expressed in the kidney of UUO mice and was sig-nificantly inhibited after AP intervention.Subse-quent cell experiments confirmed that overexpres-sion of lncRNA Gm51500 could up-regulate TGF-β-induced renal tubular cell fibrosis and Adam12 ex-pression.Cell recovery experiments confirmed that Adam12 overexpression reversed the inhibitory ef-fect of AP on renal tubular cell injury and fibrosis.CONCLUSION:Huangqi sanqi mixture can improve renal fibrosis.Based on transcriptomic sequencing,lncRNA Gm51500/Adam12 axis may be a potential target for Huangqi sanqi mixture to improve renal fibrosis.
