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). Here, MMRN1 is linked to human papilloma virus infection.
