Genes expressed differentially in chondrocytes treated with or without resveratrol (RSV). a Scatter plot of the genes expressed differentially. Red dots referred to upregulated genes, green dots referred to downregulated genes, gray dots referred to no change. b Cluster heatmap of the genes expressed differentially in chondrocytes treated with/without RSV. Blue referred to downregulated genes and purple referred to upregulated genes. c Volcano plot of the genes expressed differentially in RSV-treated chondrocytes. Red dots referred to upregulated genes, green dots referred to downregulated genes and gray dots referred to no change. d Gene ontology analysis of the genes expressed differentially. The conversion of color from green to red indicates the -log10 (P value) expression level from the low to high. The size of circles indicates gene counts, with larger circles representing larger gene counts. e KEGG pathway analysis of the genes expressed differentially. The change of color from green to red indicates the -log10 (P value) expression value from the low to high. The size of circles indicates gene counts, with larger circles representing larger gene counts. f Protein-protein interaction of the genes expressed differentially in chondrocytes treated resveratrol. g Top 2 MCODE models in differentially expressed genes in chondrocytes treated RSV
