Diagram summary of the effect of Epstein–Barr virus EBV and high-risk human papillomaviruses (HPV) co-infection in the initiation and intensification of epithelial–mesenchymal transition (EMT) event. EBV onco-proteins, LMP1, LMP2A, and/or EBNA1 can initiate EMT and, therefore, cancer progression; while, co-expressing E5 and/or E6/E7 of high-risk HPV onco-proteins could enhance the progression of EMT leading to a more aggressive metastatic cancer, as previously reported by Al Moustafa et al. (9) and Jiang et al. (95).
