Figure 6.

Detection of protein–protein networks through Markov Clustering (MCL) using STRING: functionalprotein association networks [49,50]. Proteins that have not been assigned to a network are not included in the figure. The proteins with a red circle can be assigned to ‘positive regulation of cell population proliferation’ and ‘tube development’, proteins with a green circle can be assigned to ‘negative regulation of cell differentiation’, and proteins with a yellow circle can be assigned to ‘cholesterol metabolic process’ within the gene ontology terms biological processes (GO:BP). Proteins with a blue circle belong to an unassigned cluster.
