Results of in silico analysis suggesting the presence of microRNA-34a (miR-34a) target sites on the genes encoding cellular entry receptors for the following viruses: platelet-derived growth factor receptor-alpha (PDGFRA) – cellular entry receptor for human cytomegalovirus; complement component receptor 2 (CCR2) – for Epstein-Barr virus; CD46 – for human herpes virus 6 and human adenoviruses group B; and herpes simplex virus entry mediators A, B, and C (HVEM-A, -B, -C). Phosphoprotein enriched in astrocytes-15 (PEA15) is a positive regulator for coxsackievirus adenovirus receptor, the cellular entry receptor for all other than group B serological groups of human adenoviruses.
