Intraperitoneal (i.p.) injection of urethane induces lung tumorigenesis in mice accomplished with a single‐driver mutation in the KRAS gene and pathological features congruent with human adenocarcinomas.[15] Thus, we induced primary lung tumors in Stk24‐deficient mice (Stk24h/h) and wild‐type mice (WT) by intraperitoneal urethane injection. This evidence concerns the gene STK24 and adenocarcinoma.
