As for KEGG analysis, the magenta module was significantly enriched in vascular smooth muscle contraction, hypertrophic cardiomyopathy, and dilated cardiomyopathy; the turquoise module was significantly enriched in the PI3K/Akt signaling pathway, focal adhesion, and ECM–receptor interaction; and the blue module was significantly enriched in human papillomavirus infection, PI3K/Akt signaling pathway, and protein digestion and absorption (Figure 2B). The gene discussed is MMRN1; the disease is dilated cardiomyopathy.
