英文摘要
We have generated and anaiyzed the mutant mouse lacking transcription factor ATF-2 gene far members.1.ATF-2 heterozygously knockout female mouse developed mammary tumours at very high ratio 18/ : Most of these tumours were adenocarcinoma scirrhus.2, By using Tip-Technology, we have found that the expressions of APC and c-jun are reduced sev folds in ATF-2 deficient MEF.3, We have found that the induction of GADD45 gene by anisomycin is inhibited in the ATF-2 defic cell line.4, The expression levels of GADD45 gene were much reduced in the tumours than in normal mammal5, ATF-2 homozygously and heterozygously knockout MEFs that express activated RAS develo tumours in nude-mouse at 100%, but wild type MEF that express activated RAS couldn't develop tumours.6, From these results we can say that ATF-2 heterozygously knockout femaie mouse have high potent to develop tumours.
