Synovial Joint Fluid Omics Researches in Osteoarthritis: An Affinity Chromatography-Based Perspective
摘要
Synovial joint fluid is the lubricant and nutrient of articular joint cartilage. Osteoarthritis research recently focused on genetics, epigenetics, proteomics, metabolomics and lipidomics. This technology not only allows the identification of phenotypes and endotypes but may also monitor the clinical, molecular and therapeutic stages of the disease. In this review, we summarized biomarker-based diagnostics of osteoarthritis. Our focus was the synovial joint fluid. Affinity chromatographic and omic-based strategies are presented. The limitations were highlighted. Insight into synovial joint fluid processing is provided. IMAC sorbent synthesis is discussed. LC–MS/MS capability after phosphopeptide enrichment is described. Outcomes of our pilot study are presented. The isolation and detection capabilities of the IMAC sorbent for other phosphostructures and their clinical use will be examined in future.
