Oncogenic aberrant expression of miR-378, miR-141, miR-144, and miR-205 in NPC have been found to promote NPC pathogenesis by affecting tumour suppression, cell cycle (phosphatase and tensin homolog (PTEN)), and enhanced cell proliferation, invasion, and migration [40,41,42,89]. This evidence concerns the gene PTEN and nasopharyngeal carcinoma.
