Analysis and identification of differentially expressed endoplasmic reticulum stress-related genes (DE-ERGs) in SONFH and control samples. (A) Volcano map of the distribution of the 1220 DEGs in the GSE123568 dataset. Red, upregulated DEGs; blue, downregulated DEGs. (B) Venn diagram of 195 DE-ERGs. (C) Heatmap of changes in expression of the top 100 DE-ERGs. Blue, downregulation; red, upregulation.
