Mechanism of Danggui Niantongtang on Adjuvant Arthritis Rats with Wind-dampness-heat Arthralgia Based on Quantitative Proteomics
To explore the mechanism of Danggui Niantongtang (DGNT) against adjuvant arthritis (AA) rats with wind-dampness-heat arthralgia by quantitative proteomics.
Method
2
Sixty SD rats were randomly divided into normal group, model group, angelica came pain soup low, medium and high dose group and methotrexate (MTX) group, each group of 10, only the rat tail root subcutaneously inactivated mycobacterium tuberculosis (Mtb) of adjuvant to build model of AA, artificial climate box intervention 16 d rheumatic fever bi syndrome model is set up, building the day began to drug intervention, The intervention lasted for 28 days. The proteins of synovial tissues in experimental rats were extracted. The differential proteins in the medium-dose DGNT group and the model group were detected and analyzed by 4D label-free quantification (4D-LFQ) proteomics. The differentially expressed proteins associated with mitochondrial pathway apoptosis were verified by immunohistochemistry and Western blot.
Result
2
A total of 4 756 proteins were identified from rat synovial tissues, of which 4 234 proteins contained quantitative information. There were 814 differential proteins between the model group and the DGNT group. As revealed by Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genome (KEGG) enrichment analyses, DGNT had an effect on the synovial proteome of AA rats with wind-dampness-heat arthralgia, and the differential proteins were enriched in the regulation of the immune system, response to acute inflammation, and apoptosis regulation. As demonstrated by the results of immunohistochemistry and Western blot, compared with the model group, the DGNT groups and the MTX group showed increased protein expression of B-cell lymphoma 2 (Bcl-2)-associated X protein (Bax) and cytochrome C (Cyt C)(
0.01), and decreased level of phosphorylated protein kinase B (p-Akt)/Akt(
P
<
0.05,
P
<
0.01).
Conclusion
2
DGNT involved multiple targets in the treatment of AA with wind-dampness-heat arthralgia and it may exert its effect in the prevention and treatment by regulating the Akt/Bax/Bcl-2 pathway and promoting the cell apoptosis in the mitochondrial pathway.
