| Research Abstract |
In this study, we generated tissue-specific A20 knockout mice. Intestine epithelium-specific A20 knockout mice did not show obvious phenotype. Skin-specific A20 knockout mice showed growth retardation after weaning. We have performed historogical analysis, but we couldn't find any defect in A20 deficient skin. Instead, we found inflammation and hyperplasia on the non-glandular portions of the stomach. These data suggests A20 gene deletion in the non-glandular portions of the stomach of skin-specific A20 knockout mice, because of ectopic expression of cre. As a result, these mice might have stomach inflammation and growth reterdation.
