Identification of DEGs. (a) Principal component analysis (PCA) plot generated from DEGs in GSE66795. (b) PCA plot generated from DEGs in GSE84844. (c) Heat map of GSE66795. (d) Heat map of GSE84844. (e) Uniform manifold approximation and projection (UMAP) showing distinct clusters of DEGs in GSE66795. (f) UMAP showing distinct clusters of DEGs in GSE84844. (g) Venn diagram of common DEGs from the two datasets. Data points in red represent upregulated genes, and those in blue represent downregulated genes. Group 1 indicates HC and group 2 indicates pSS.
