Fig. 1From: Identification of potential autophagy-related genes in steroid-induced osteonecrosis of the femoral head via bioinformatics analysis and experimental verificationDifferentially expressed autophagy-related genes in SONFH and non-SONFH samples. a Principal component analysis of GSE123568. b Volcano plot of 222 differentially expressed autophagy-related genes. The red dots represent the significantly upregulated genes and the blue dots indicate the significantly downregulated genes. c Hierarchical clustering heatmap of the 34 differentially expressed autophagy-related genes in SONFH and non-SONFH samplesBack to article page
