Protein–protein interaction (PPI) network of the ‘key’ genes and identification of hub genes: (a) Protein–Protein Interaction network of the 45 key genes generated using STRING, (b) A network of ten hub genes were obtained using cytoHubba, an application of Cytoscape. The nodes are colored based on their scores obtained using MCC. The darker the node, the greater its score (red) and the lower scores are represented as yellow.
