Fig. 1From: KLF9 and EPYC acting as feature genes for osteoarthritis and their association with immune infiltrationScreening of differentially expressed genes. a Volcano map of DEGs; red represents up-regulated differential genes, black represents no significant difference genes, and green represents down-regulated differential genes. b The thermal map of expression level of different genes in every synovial tissue sample, the redder the color, the higher the expression, the bluer the color, the lower the expressionBack to article page
