Fig. 2.

Analysis of 22 hub differentially expressed genes in PD. (A) Venn diagram presents the genes intersection. (B) The abundance of 22 hub differentially expressed genes in age-matched PD samples and normal controls. (C) Pearson’s correlation at the transcriptomic level among the 22 hub differentially expressed genes. (D) Protein-protein interaction network among the 22 hub differentially expressed genes. Nodes in cyan, in pink, and in red represent the ferroptosis-related genes, PD-risk genes, and PD-deleterious genes, respectively. Edges denote the interaction, and its size reflect the intensity.
