Fig. 4From: Proteome analysis identified proteins associated with mitochondrial function and inflammation activation crucially regulating the pathogenesis of fatty liver diseaseProtein-protein interaction (PPI) analysis of differential expressed proteins identified by mix-sampled proteome data. A Interaction networks of all differencially expressed proteins showing significantly enriched pathways and key proteins (http://string-db.org/). Circle size represents the interaction intensity of proteins. Circle color represents the regulation direction, up-regulated (Fold change > 1.2, P < 0.05) proteins in red and down-regulated (Fold change < 1/1.2, P < 0.05) proteins in green. Square color represents the significance of enriched pathways. B protein-protein interaction networks of differencially expressed proteins. Circle size represents the interaction intensity of proteins. Circle color represents the same sense as in ABack to article page
