Oncogenes EGFR and ras are frequently mutated and activated in human lung cancers. In this report, we found that both EGFR and Ras signaling can upregulate RNA helicase DDX59 in lung cancer cells. DDX59 can be induced through the mitogen activated protein kinase (MAPK) pathway after EGFR or Ras activation. Inhibitors for Ras/Raf/MAP pathway significantly decreased DDX59 expression at both protein and mRNA levels. Through immunohistochemistry, we found that DDX59 protein expression correlated with Ras and EGFR mutation status in human lung adenocarcinoma. Finally, through a xenograft nude mice model, we demonstrated that DDX59 is pivotal for EGFR mutated lung cancer cell growth in vivo. Our study identified a novel protein downstream of Ras and EGFR, which may serve as a potential therapeutic drug target for lung cancer patients.
