Genetic association analysis of the IGFBP7, ADAMTS3, and IL8 genes as the potential osteoarthritis susceptibility that maps to chromosome 4q.
OBJECTIVES: To determine by genetic association analysis whether the 4q functional candidate genes IGFBP7, ADAMTS3, and IL8 might encode for susceptibility to osteoarthritis (OA). METHODS: Expression of IGFBP7, ADAMTS3, and IL8 in adult OA articular cartilage chondrocytes was demonstrated by reverse transcription-polymerase chain reaction. The genes were screened for common polymorphic DNA variants by direct sequencing of exons, intron-exon boundaries, and the 5' and 3' untranslated regions. ...Expand abstract
