LATS2 and nasopharyngeal carcinoma: To determine LATS2 expression in NPC, quantitative real-time PCR was performed to evaluate the expression levels of LATS2 transcripts in the NPC cell lines CNE1, CNE2, 5-8F and C666-1, in an immortalized primary nasopharyngeal epithelial cell line NP69, as well as in three NPC biopsies and their paired normal tissues.
