MEG9 and nasopharyngeal carcinoma: We showed that the lncRNAs MEG9, MIR381HG, and MEG8, from which miR-409-3p, miR-381-3p and miR-370-3p are derived, were also upregulated upon reactivation in AGS and nasopharyngeal carcinoma cells lines and occurred very early in the lytic cycle at the time of BZLF1 expression.
