Fig. 4From: Towards a potential pan-cancer prognostic signature for gene expression based on probesets and ensemble machine learningProtein-protein physical interaction network of our proposed pan-cancer signature. We generated this network with STRING [55]: each node represent a protein generated by a protein-coding gene of our proposed pan-cancer signature, and each edge represents a physical interaction between two proteins. Some nodes contain the known or predicted 3D structure of their proteins. The colors of the edges can represent several types of interactions [55]. Confidence threshold: 0.4 mediumBack to article page
