ND, not described;
deletion is driven by intranasal delivery of Adeno-Cre;
Trp53 is co-deleted with Atg5 or Atg7 in the same cells;
in autophagy-proficient setting, lung tumors (early and late) are adenomas and adenocarcinomas under Trp53+/+ and Trp53-null conditions, respectively, whereas in autophagy-deficient setting, late lung tumors are benign oncocytomas regardless of Trp53 status.
