Significance
Lung cancer remains one of the leading killers in the United States and around the world. Platinum agents, including cisplatin, are the first line treatment in lung cancer, including non-small cell lung cancer (NSCLC), which is the predominant form of lung cancer. In this study, we have evaluated Mad2 cell-cycle checkpoint gene silencing using small interfering RNA (siRNA) delivered systemically using epidermal growth factor receptor-targeted chitosan nanoparticles in drug sensitive and resistant models of NSCLC. Our results show that Mad2 gene silencing using targeted chitosan nanoparticles has tremendous potential in overcoming platinum resistance in NSCLC.
