STK11 and infection: To investigate the stemness property in relation to LKB1 deficiency, we comparatively analyzed the RNA‐Seq data from lung ADC from KrasLSL‐G12D/+ (K), KrasLSL‐G12D/+; Lkb1flox/flox (KL), and KrasLSL‐G12D/+; P53flox/flox (KP) mouse models, in which the oncogenic KrasG12D allele is conditionally activated following Ad‐Cre infection by nasal inhalation as described previously (Li et al, 2015).
