Volcano plot of differentially expressed genes in HBB low-expressing and high-expressing chondrocytes. C. Violin plots demonstrating the expression of representative genes in HBB low-expressing and HBB high-expressing chondrocytes chondrocytes. D. KEGG biological process enrichment analysis of differentially expressed genes between HBB low-expressing and HBB high-expressing chondrocytes. E. GSEA enrichment illustrating the difference of genes expression profile in HBB high-expressing and HBB low-expressing chondrocytes in pathways related with chondrocytes and respiration
