Fig. 1From: Autophagy-related genes analysis reveals potential biomarkers for prediction of the impaired walking capacity of peripheral arterial diseaseDifferentially expressed autophagy-related genes in PAD and healthy samples. A Principal component analysis for GSE57691. B Heatmap of the 20 differentially expressed autophagy-related genes in PAD and healthy samples. C Volcano plot of the 20 differentially expressed autophagy-related genes. The red dots represent the significantly up-regulated genes and the blue dots indicate the significantly down-regulated genesBack to article page
