title: [Down-regulation of Nrf2 enhances the cytotoxicity of Oxaliplatin to H460 cells].
abstract: To establish a stable H460 cell line with Nrf2 down-regulation to study the role of Nrf2 in Oxaliplatin resistance.
  
  
  
  Nrf2 down-regulated H460 cell line was obtained by transfecting cells with pRS-hNrf2 and followed by screening for Nrf2 expression by Western blotting. The cell lines were further characterized by analysing cellular GSH levels and cytotoxicity to anti-cancer drugs with MTS.
  
  
  
  Nrf2 down-regulated H460 cell lines were established successfully. Cellular GSH level reduced significantly in the H460-C9 and H460-C13 compared to control cells (P(C9)= 0.00249, P(C13)= 0.03944). Down-regulation of Nrf2 in H460 sensitized the anti-cancer effect of Oxaliplatin and Doxorubicin.
  
  
  
  Nrf2 plays an important role in drug resistance. Down regulation of Nrf2 in H460 cell enhances cytotoxicity of Oxaliplatin.
