KRAS and neoplasm: Of relevance here, previous research has revealed that Fak1 activity is necessary for tumor progression in Kras;Cdkn2a‐mutant and Kras;Lkb1‐mutant murine models of LUAD (Konstantinidou et al, 2013; Gilbert‐Ross et al, 2017), suggesting that Fak1 may be a critical oncogene in certain subsets of KRAS‐mutant LUAD tumors.
