ABSTRACT
Objective:
To observe the effect of Fengshi Qutong capsule (FSQTC) on protein kinase B(Akt) and mitogen-activated protein kinase (MAPK) signaling pathways of rheumatoid arthritis (RA).Method:
Collagen-induced arthritis (CIA) was induced in SD rats, and the synovial membranes of the knee joints were prepared after 19 days of oral administration of 0.25, 0.5, 1 g·kg-1 FSQTC. MH7A cells were induced by tumor necrosis factor-α (TNF-α, 20 μg·L-1) in vitro, and human umbilical vein endothelial cells (HUVEC) were induced by vascular endothelial growth factor (VEGF). FSQTC (0.02, 0.1, 0.5 μg·L-1) were added to MH7A/HUVEC cells, and then the cells were collected. Proteins of synovial tissue, MH7A and HUVEC cells were extracted, and then were detected the expresstion of p-Akt, p-p38 MAPK, p-extracellular signal-regulated kinase(ERK) and p-Jun n-terminal kinase(JNK) by Western blot.Result:
The expression levels of p-Akt, p-p38 MAPK, p-ERK and p-JNK in the synovial membrane of CIA model were significantly increased compared with normal group (P-1·d-1 FSQTC significantly decreased their expression levels (PPα or VEGF were increased (P-1 FSQTC (PPConclusion:
FSQTC can down-regulate the abnormal activation of Akt and MAPK signaling pathways in the synovial membrane of CIA rats, fibroblast synovial cells and vascular endothelial cells, which is related to the inhibition of synovial angiogenesis in the treatment of RA.
