Stem Cell Related Patent Number US6313373
| Title: | Tissue specific promoters and transgenic mouse for the screening of pharmaceuticals | | Inventors: | Eckert, Richard L.; Cleveland Hts., OH, USA
Crish, James F.; North Olmsted, OH, USA | | Summary: | This invention describes human involucrin (hINV) sequences having tissue-specific and cell type-specific promoter activity. Further disclosed are sequences which direct expression to suprabasal cells of stratifying epithelia, as well as methods for the production of transgenic animals which contain a hINV promoter sequence directing the expression of human papillomavirus 16 oncogenes, or other oncogenes. Such animals display cervical and epidermal hyperplasias as well as cancer of the trachea, esophagus, colon, epidermis, anus/rectum, lymph nodes, spleen and lung. Methods are also described for the use of this model in the screening of potential anti-neoplastic compounds, carcinogens, and co-carcinogens for a number of cancers. | | Abstract: | The present invention provides human involucrin (hINV) sequences having tissue specific and cell type specific promoter activity.
