| Research Abstract |
To generate a novel mouse model in which TGF-βsignaling is blocked and COX-2/PGE_2 pathway is activated, we tried construction of transgenic mice expressing Cre in gastric epithelial cells using K19 gene promoter. However, we found that K19 promoter is active in whole body during embryogenesis and its expression efficiency is very low in adult stomach, indicating that other promoter than K19 is required for future construction of stomach specific Cre mice.
