abstract：:Although mutations of p53 and KRAS and activation of NF-κB signaling have been highly associated with chemoresistance and tumorigenesis of lung cancer, the interactive mechanisms between two of p53, KRAS, and NF-κB are elusive. In the present study, we first observed that blocking of NF-κB function in KRAS mutant A549...
