Differentially expressed lncRNA in resveratrol-treated chondrocytes. A Comparison of expression value between before normalization and after normalization; the vertical axis represents the different treatment samples, and the horizontal axis represents gene expression level (log2 scale). B Volcano plot of the differentially expressed lncRNAs in resveratrol-treated chondrocytes, red dots represented upregulated genes, green dots represented downregulated genes, and black dots represented non-significant genes. C Heatmap of the differentially expressed lncRNAs in resveratrol-treated chondrocytes; the color (from green to red) represents gene expression intensity from low to high
