PTEN and nasopharyngeal carcinoma: In the present study, we discovered and experimentally confirmed an additional binding site for this viral miRNA within the 3′UTR of PTEN, and observed that silencing of PTEN mimicked EBV-miR-BART7-3p-induced tumorigenic phenotype, providing additional evidence that EBV-miR-BART7-3p did directly inhibit PTEN in NPC tumorigenesis.
