RESUMEN
To observe the effect of Xinfeng Capsules on rheumatoid arthritis (RA) B lymphocytes,inflammatory mediators,FAK/CAPN/PI3K pathway,in order to explore the mechanism of Xinfeng Capsules in improving clinical symptoms of RA.Joint and systemic symptoms of RA patients were observed,and laboratory indicators[hemoglobin (HGB),platelet count (PLT),erythrocyte sedimentation (ESR),immunoglobulin (Ig) G,Ig A,Ig M,rheumatoid factor (RF),anti-cyclic citrulline antibody (CCP-AB),C-reactive protein (CRP)]were detected.ELISA was used to detect serum interleukin (IL)-1ßï¼IL-10,IL-33,chemokine 5 (CCL5),and vascular endothelial growth factor (VEGF).CD3~-CD19~+B cells were measured by flow cytometry.Western blot was used to detect FAK,p-FAK,CAPN,PI3K protein.The results showed that Xinfeng Capsules could significantly alleviate RA joint and systemic symptoms and improve clinical efficacy.And Xinfeng Capsules could increase HGB,decrease PLT,CCP-AB,CRP,ESR index,upregulate IL-10 expression,and down-regulate IL-1ßï¼IL-33,CCL5,VEGF,CD3~-CD19~+B cells,FAK,p-FAK,CAPN,PI3K expressions (P<0.01).Based on the above results,Xinfeng Capsules may reduce the expression of CD3~-CD19~+,regulate the balance of inflammatory cytokines and chemokines,inhibit abnormal activation of FAK/CAPN/PI3K pathway,and improve clinical symptoms of RA.

AIMS: Experimental evidence demonstrated a crucial role of TROAP (Trophinin-associated protein) in regulating the cell proliferation of multiple tumors, while TROAP expression and function were largely unknown in glioma. We aimed to investigate the oncogenic role of TROAP and its potential mechanisms in gliomagenesis. METHODS: Four gene expression databases (GEO, TCGA, GTEx and CCLE) were enrolled in our study and used for TROAP expression and survival analysis. TROAP expression was quantified by qRT-PCR, western blot and immunohistochemistry assays in glioma tissues and cell lines. TROAP knockdown and overexpression vector were constructed and transfected into glioma cells. CCK-8, colony formation, transwell, and wound healing assays were used to evaluate cell viability, migration and invasion, flow cytometry to determine cell cycle arrest. Gene set enrichment analysis (GSEA) was conducted to screen the pathway involved in TROAP-high phenotype. The expression of cell cycle and Wnt/ß-Catenin signaling proteins were analyzed by immunofluorescence and western blot. RESULTS: Based on the bioinformatic analysis and a series of functional assays, we found the TROAP was enriched in glioma tissues and cell lines, its overexpression was correlated with the clinicopathologic characteristics and poor prognosis. TROAP knockdown inhibited cell proliferation, migration, invasion, and G1/S cell cycle arrest compared with control group in glioma. Mechanism analysis revealed that TROAP activated Wnt/ß-Catenin pathway and upregulated its downstream targets expression, while silencing ß-Catenin or Axin2 could reverse the tumor-promoting effects caused by TROAP, confirming that TROAP-induced malignant phenotype and tumorigenesis via Wnt/ß-Catenin signaling pathway. CONCLUSION: The present study found that TROAP accelerated the progression of gliomagenesis through Wnt/ß-Catenin pathway, and TROAP might be considered as a novel target for glioma therapy.
