84  New plasma membrane proteins have unique mechanisms and effects on NSCLC  Gefitinib effectively inhibits particular EGFR mutants  SiRNA could be used as a possible treatment for various mutated proteins

85  How does cisplatin enter the nucleus?  Roles and mechanisms behind the various mutated proteins involved in lung cancer  New drugs, secondary mutations
