綜觀全世界,肺癌發生率於各種癌症中佔12.8%,且死亡率高達90%,更驚人的是1990年全球因肺癌而死亡的人數與1950年相較之下有四倍的增長。目前發現肺腺癌大多治療方式為開刀切除、化學藥物或是放射線治療,然而當肺腺癌的腫瘤形成後,有八成以上會造成遠端轉移,其中包括了腦部、腎臟、肝臟、及骨骼等器官,使肺腺癌的治療更加困難。迄今,世界上肺癌的發生機率仍然不斷的攀升,因此必須要能對肺癌生成的機制進行分子層次之剖析,進而提出預防措施以防範於未然。本發明係有關於一種於非人類的基因轉殖動物中表現外源蛋白質之方法,特別係指以基因工程製備能於肺部細胞專一性表現人類A型血管內皮新生因子之非人類的基因轉殖動物,用以建立一動物模式,分析肺腺癌發生之相關機制,進以測試評估不同治療藥物對於肺腺癌生長之影響。 Taking a view in the whole world, the incidence rate of lung cancer among all cancers is 12.8% and the mortality rate is up to 90%. It is more amazing that the number of persons dead by lung cancer in 1990 has increased to be 4 times of that in 1950. Till now, the incidence rate of lung cancer has been continued increasing. Thus, there is a need to analyze the induction mechanism of lung cancer in a molecular level so as to propose measures for preventing from it in future. A method to produce extraneous-source protein expression in non-human transgenic animals. Specially, to establish an animal tumor model of lung adenocarcinoma by lung tissue-specific expression of human vascular endothelial growth factor (VEGF) in non-human transgenic animals. This invention provides an animal model to elucidate the mechanisms of tumor development and a novel platform to test the anti-cancer efficiency in the treatments of different medicines.
