miR-BART3 targets the introduction of importin 7 (IPO7), induces the pro-inflammatory cytokine IL-6, and plays an anti-apoptotic role against caspase 3, and miR-BHRF1–1 enhances EBV replication by down-regulating host p53 in nasopharyngeal carcinoma. Here, IPO7 is linked to nasopharyngeal carcinoma.
