The function analysis revealed the genes in the ceRNA network mainly involved in the Nitrogen compound metabolic process, COPII-coated ER to Golgi transport vesicle, CAMP response element protein binding process in the GO term annotation, meanwhile, it’s showed that the Hepatitis B, GnRH signaling pathway, Prion disease and Human T-cell leukemia virus 1 infection were the most enriched KEGG pathway, and interestingly, 3 of them were closely related to the virus infection. Here, CAMP is linked to prion disease.
