Fig. 2From: Identification of biomarkers, immune infiltration landscape, and treatment targets of ischemia–reperfusion acute kidney injury at an early stage by bioinformatics methodsPrincipal components analysis (PCA) score trajectory plots, heatmaps, and volcano plots of the two datasets. A, B Principal components analysis (PCA) score trajectory plots (A: GSE87024; B: GSE34351) indicate obvious differences between the ischemic acute kidney injury (IRI) and control (CON) group. C, D Heatmaps and showing the differentially expressed genes (DEGs) between the IRI and CON group. The red color represents the up-regulated genes, while the blue color represents the down-regulated genes. Samples are sorted by columns, and genes are sorted by rows. E, F Volcano plots showed the significantly DEGs in two datasets (A: GSE87024; B: GSE34351). Red points represent up-regulated, and green represent down-regulated genes. The differences are set as |log FC|> 1.5 and P < 0.05Back to article page
