Two-dimensional PCA cluster plot before and after PCA for the combined expression profile. A, B shows two-dimensional PCA cluster plots before and after PCA for the combined expression profile. After correcting the batch effect, we combined the four GEO datasets GSE27276, GSE2378, GSE9944 (GPL8300) and GSE9944 (GPL571) into the expression profiles of 110 samples (control group: 67 cases; POAG group: 43 cases). C DEG volcano plot; red represents upregulated differentially expressed genes, and green represents downregulated differentially expressed genes
