Association between IL-4 gene polymorphisms, IL-4 serum levels, and ankylosing spondylitis
Serum matrix metalloproteinases-3 levels in patients with ankylosing spondylitis
Cumulated evidence indicates that matrix metalloproteinase-3 (MMP-3) is significantly involved in cancer progression. Recent studies yielded conflicting results regarding the association between serum MMP-3 and ankylosing spondylitis (AS). To clarify this correlation, we performed a meta-analysis. Potential relevant studies were identified by searching the following databases: PubMed, Embase, CINAHL, Science Citation Index database, the Cochrane Library, Current Contents Index, Chinese Biomedical, the Chinese Journal Full-Text, and the Weipu Journal.
Meta-analysis of differentially expressed genes in ankylosing spondylitis
The purpose of this study was to identify differentially expressed (DE) genes and biological processes associated with changes in gene expression in ankylosing spondylitis (AS). We performed a meta-analysis using the integrative meta-analysis of expression data program on publicly available microarray AS Gene Expression Omnibus (GEO) datasets. We performed Gene Ontology (GO) enrichment analyses and pathway analysis using the Kyoto Encyclopedia of Genes and Genomes. Four GEO datasets, including 31 patients with AS and 39 controls, were available for the meta-analysis.
Expression of TNF-α, VEGF, and MMP-3 mRNAs in synovial tissues and their roles in fibroblast-mediated osteogenesis in ankylosing spondylitis
The aim of this study was to explore the mRNA levels of tumor necrosis factor-α (TNF-α), vessel endothelial growth factor (VEGF), and matrix metalloproteinase-3 (MMP-3) in synovial tissues in ankylosing spondylitis (AS), and to analyze the functions of these proteins in the differentiation of AS synovial tissue fibroblasts into osteoblasts (OB) and osteoclasts. Synovial tissue samples from 22 AS patients and 22 normal individuals were collected.
Tumor necrosis factor receptor-II nt587 polymorphism in Chinese Han patients with ankylosing spondylitis
We aimed to explore the association between the onset of ankylosing spondylitis (AS) and nt587 polymorphisms of the tumor necrosis factor receptor II (TNFRII) gene in the Han population of Hunan Province, China. Correlation analysis was performed in a case-control study involving 100 AS cases and 100 healthy controls. The nt587 single nucleotide polymorphism of the TNFRII gene was examined by polymerase chain reaction-restriction fragment length polymorphism.
Lack of association of the G22A polymorphism of the ADA gene in patients with ankylosing spondylitis
Genes located outside the HLA region (6p21) have been considered as candidates for susceptibility to ankylosing spondylitis. We tested the hypothesis that the G22A polymorphism of the adenosine deaminase gene (ADA; 20q13.11) is associated with ankylosing spondylitis in 166 Brazilian subjects genotyped for the HLA*27 gene (47 patients and 119 controls matched for gender, age and geographic origin).
Association between IL-1RN gene polymorphisms and susceptibility to ankylosing spondylitis: a large Human Genome Epidemiology review and meta-analysis
We made a Human Genome Epidemiology review and meta-analysis to examine a possible association between interleukin-1 receptor antagonist (IL-1RN) polymorphisms and susceptibility to ankylosing spondylitis (AS). Studies of IL-1RN polymorphisms and susceptibility to AS were found by searching the Pubmed, Cochrane library, Embase, Web of Science, Springerlink, CNKI, and CBM databases. Data were extracted by 2 independent reviewers. The meta-analysis was performed with the Review Manager Version 5.1.6 and STATA Version 12.0 software.
