Synovial tissue samples from 22 AS patients and 22 normal individuals were collected. In situ hybridization was utilized to detect TNF-α, VEGF, and MMP-3 transcripts. After counting numbers of positive cells, Spearman analysis was used to determine the correlation between transcriptional levels of the three mRNAs and the AS disease activity index (BASDAI) and the C-response protein (CRP) levels. With the addition of TNF-α, VEGF, or both factors into cultured normal synovial fibroblasts, osteocalcin (bone gla protein, BGP) secretion levels were compared. We found that expression of TNF-α, VEGF, and MMP-3 was identified exclusively in the disease group. mRNA levels were significantly positively correlated with BASDAI (r = 0.42, 0.38, and 0.47, respectively; P < 0.05) and CRP (r = 0.44, 0.34, and 0.47 respectively; P < 0.05) scores. The secretion level of BGP in normal synovial fibroblasts increased progressively with increasing concentrations of VEGF or TNF-α (P < 0.01 compared to levels before treatment). Furthermore, co-incubation using both VEGF and TNF-α significantly elevated BGP levels compared to the single addition of VEGF or TNF-α (P < 0.01). These results suggest TNF-α, VEGF, and MMP-3 might directly participate in the differentiation of fibroblasts into OBs."xsd:string |
