Fig. 4From: Cardiac proteomics reveals the potential mechanism of microtubule associated protein 4 phosphorylation-induced mitochondrial dysfunctionProtein-protein interaction (PPI) analysis. The interaction network of differential expressed proteins (DEPs) was analyzed using Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database. Yellow nodes represented target proteins and green nodes represented the related proteins which interact with the target proteins directly. Red circles indicated interesting proteinsBack to article page
