PXN and nasopharyngeal carcinoma: In this study, we determined the expression pattern of PXN‐AS1‐L in NPC tissues and cell lines, analyzed the correlation between PXN‐AS1‐L expression levels and survival of NPC patients, and explored the roles of PXN‐AS1‐L in NPC cell proliferation, migration, and invasion, and in vivo NPC tumorigenesis.
