Copper-transporting P-type adenosine triphosphatase (ATP7B) is reportedly associated with platinum drug resistance in various solid carcinomas. However, the impact of ATP7B on platinum drug resistance in non-small cell lung cancer (NSCLC) remains unknown. We investigated ATP7B expression in nine human NSCLC xenografts using real-time polymerase chain reaction (PCR) and immunohistochemistry, and examined the relationship between the expression level of ATP7B and in vivo cisplatin (CDDP) sensitivity. ATP7B mRNA expression was significantly correlated with in vivo cisplatin sensitivity [coefficient of determination (R(2))=0.949, p=0.005]. ATP7B protein was detected in the nine xenografts. The ATP7B protein expression level was comparable to that of ATP7B mRNA. ATP7B mRNA and protein expression levels in the CDDP-resistant xenografts were significantly higher than those in the CDDP-sensitive xenografts (p=0.0389 and p=0.0357, respectively, Mann-Whitney U test). These results suggest that ATP7B is a CDDP-resistance marker in human NSCLC xenografts in vivo.
