摘要: 摘要: 激活蛋白-2 (Activating protein, AP-2) 转录因子家族包括AP-2α、β、γ、δ、ε五个成员,在调节细胞增殖、分化和凋亡以及哺乳动物的胚胎发育中起到重要作用;近年研究发现激活蛋白-2与乳腺癌的发生相关,至少三个AP-2家族成员AP-2α、AP-2β、AP-2γ在乳腺癌中表达;抑制癌基因P53和WWox、转录共激活物DEK、癌基因HER2的表达、以及AP-2蛋白质修饰状态是调控AP-2在乳腺癌中作用的重要因素。

Abstract: Abstract:AP-2,a nuclear transcription factor family ,are involved in the regulation of cell proliferation, differentiation, apoptosis and carcinogenesis.At least 3 of the five AP-2 family members identified to date, AP-2a, AP-2βand AP-2γ, are related with the development of the breast cancer; transactivation fuction of AP-2 is regulated by tumor suppressor gene WWOX and P53、HER2 oncogene、trascriptional coactivators and AP-2 protein modifications.

Key words: activator protein-2, HER2 oncogene , breast cancer
