CCL2 and arthritic joint disease: 3 genes namely of C-C motif chemokine 2 (CCL2; FC = 2.08), vascular endothelial growth factor (VEGF; FC = 2.99) and matrix metalloproteinase 3 (MMP3; FC = −1.95) out of these 47 DEGs are involved in an arthritis pathway showing minor changes in the presence of HA in this context.
