Abstract:
:Activation of the epidermal growth factor receptor (EGFR) contributes to the pathogenesis of non-small-cell lung carcinomas (NSCLC) and gefitinib, a selective reversible EGFR inhibitor, is effective in treating patients with NSCLC. However, clinical resistance to gefitinib is a frequent occurrence highlighting the need for improved therapeutic strategies. Melanoma differentiation associated gene-7 (mda-7)/Interleukin-24 (IL-24) (mda-7/IL-24) displays cancer-selective apoptosis induction when delivered via a replication-incompetent adenovirus (Ad.mda-7). In this study, the effect of Ad.mda-7 infection, either alone or in combination with gefitinib, was analyzed in a panel of NSCLC cell lines carrying wild-type EGFR (H-460 and H-2030) or mutant EGFR (H-1650 and H-1975). While H-2030 and H-1650 cells were sensitive, H-460 and H-1975 cells were resistance to growth inhibition by Ad.mda-7, which was reversed by the combination of Ad.mda-7 and gefitinib. This combination increased MDA-7/IL-24 and downstream effector double-stranded RNA-activated protein kinase (PKR) protein expression, promoting apoptosis induction of NSCLC cells. Inhibition of PKR significantly inhibited apoptosis induction by Ad.mda-7 when administered alone but not when used in combination with gefitinib. The combination treatment also augmented inhibition of EGFR signaling. Our findings indicate that a combinatorial treatment with Ad.mda-7 and gefitinib may provide benefit in the treatment of NSCLC, especially in patients displaying resistance to clinically used EGFR inhibitors.
