Research Abstract |
Brain tumor induction in p53 knock-out mice by transplacental exposure to ethylnitrosourea (ENU) was attempted. Three out of 80 (4%) p53(+/-) mice and one of 10 (10%) p53(-/-) mice who prenatally exposed to ENU developed brain tumors. Mice #400 and #505, both of whom are p53(+/-), developed brain tumor (possibly schwannoma) when they are about 30 weeks old. Mice #537(p53[-/-]) and #370 (p53[+/-]) developed gliomas at about 10 weeks old. We should need to increase the incidence of brain tumor induction.
