Transgenic mice bearing the polyomavirus large T antigen directed by 2.1 kb of the keratin 19 promoter develop bronchiolar papillary tumors with progression to lung adenocarcinomas.

Abstract excerpt

Keratin 19 is an intermediate filament protein produced by cells of simple epithelia and basal cells of stratified epithelia of different organs. These cell types are associated with important human cancers. We have used the keratin 19 promoter to target the expression of the polyomavirus (Py) large T-antigen, an immortalizing oncogene known to bind to the tumor suppressor retinoblastoma gene product, to...
