  1. Differently synthesized proteins in OA chondrocytes were subjected to pathway analysis, by querying the Wikipathways database, using the WebGestalt web tool. Enriched pathways are grouped into four categories based on the biological processes participating. Proteins assigned to each pathway are listed in “gene names” column. AdjP-value corresponds to p-value adjusted by the multiple test adjustment, during enrichment test.
