Functional analyses of significantly expressed lncRNAs and mRNAs in serum exosomes of patients with RA. A–B GO analysis and KEGG pathway enrichment of the DE-lncRNAs in patients with RA compared with healthy controls (A) and patients with OA (B). C–D GO analysis and KEGG pathway enrichment of the DE-mRNAs in patients with RA compared with healthy controls (C) and patients with OA (D) G O, Gene Ontology; KEGG, Kyoto Encyclopedia of Genes and Genomes; DE-lncRNAs, differentially expressed lncRNAs; DE-mRNAs, differentially expressed mRNAs; RA, rheumatoid arthritis; OA, osteoarthritis
