BST2 and nasopharyngeal carcinoma: In previous studies, we generated the cisplatin-sensitive subclone S16 from CNE2 cells21 and found that, as evidenced by mRNA microarray data, BST2 is downregulated in S16 cells compared with the cisplatin-resistant parental CNE2 cells.22 In the present study, BST2 was identified as a platinum-resistant factor in NPC.
