Another pharmacologic approach studied in the setting of NPC is the use of molecules targeting the Inhibitor of Apoptosis Protein 2 (c-IAP2), as high concentrations of c-IAP2 have been identified in NPC cell lines, supporting the hypothesis that c-IAP2 may play a critical role in the molecular pathogenesis of NPC. This evidence concerns the gene BIRC2 and nasopharyngeal carcinoma.
