MMRN1 and human papilloma virus infection: Cellular component analysis suggested that similar genes were mainly concentrated in the extracellular matrix, collagen trimer, extracellular region, endoplasmic reticulum lumen, extracellular space, etc. KEGG pathway enrichment analysis showed that similar genes were mainly enriched in protein digestion and absorption, the PI3K–Akt signaling pathway, human papillomavirus infection, focal adhesion, and ECM–receptor interaction (Fig. 4f).
