PIK3CA and cytomegalovirus infection: We performed Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis to identify the co-expressed mRNAs most associated with autophagic LncRNAs, and determined that the top five enriched signaling pathways were involved in autophagy, human papillomavirus infection, PI3K–Akt pathway, human cytomegalovirus infection, and apoptosis (Figure 6C).
