Cluster analysis and correlation analysis of the significantly different expression genes from tumor tissues within ECM receptor interaction and complement & coagulation cascades signalings. a The gene-gene interaction network of the treatment response-related genes involved in ECM receptor interaction and complement & coagulation cascades signalings in tumors. The gene connection clusters are colored red (Cluster 1), green (Cluster 2), and blue (Cluster 3). The solid and the dotted lines indicate connection within the same and different clusters respectively. b A heatmap showing the correlation of the 25 treatment response-related genes with the oncological features including apoptosis, EMT, and proliferation in tumors (Spearman Correlation test, p < 0.05)
