GO and KEGG enrichment analysis revealed that target mRNAs from the CeRNA regulatory network were mainly related to the immune system, response to inflammation, and antiviral response, such as immune system-related Th1 and Th2 cell differentiation, Th17 cell differentiation, and T cell receptor signaling pathway; antiviral response-related human T-cell leukemia virus 1 infection, Epstein-Barr virus infection, and human immunodeficiency virus 1 infection; inflammation response-related Notch signaling pathway, PPAR signaling pathway, and mTOR ­signaling pathway. Here, PPARA is linked to Epstein-Barr virus infection.
