Wnt1 inducible signaling pathway protein-3 regulation and microsatellite structure in arthritis.

Abstract

WISP3 gene expression is higher in RA synovium and FLS compared with OA and normal synovial tissue and is further induced by proinflammatory cytokines in vitro. Protein levels are not increased, indicating discoordinate regulation of WISP3 protein and mRNA. Although functionally relevant mutations were observed in genomic DNA, they were noted in both OA and RA samples.
