neoplasm

increased lung tumor incidence ( J:119477 , J:216266 , J:299900 )

• treatment with adenoviral Cre to induce oncogenic Kras expression results in lung tumor development, but causes a lower tumor burden and decreased overall tumor area compared to induced mutants on a Spry2-null background (J:119477)

• 20% and 100% of mice develop lung lesions at 6 weeks and 20 weeks, respectively, post intranasal adenoviral cre administration (J:216266)

• all mice delivered with an adenovirus expressing cre recombinase through nasal inhalation at 8 weeks of age develop lung tumors (J:299900)

increased lung adenoma incidence ( J:207982 )

• mice develop lung adenomas with a few adenocarcinomas following intratracheal administration of an adenovirus expressing Cre (Ad-Cre)

• treatment with MLN4924, a small molecular inhibitor of NAE, beginning at 13 weeks after Ad-Cre administration reduces tumor burden, with a reduction in both number of hyperplastic areas and adenomas and size of the tumors

increased lung adenocarcinoma incidence ( J:207982 )

• a few adenocarcinomas develop in mice following Ad-Cre administration
