目的構建含木薯linamarase (lis)基因的穩(wěn)定轉染肝癌細胞系，并對其生物學特性進行研究。方法 應用PCR法從木薯的DNA中擴增出lis基因，將其克隆至pcDNA3.1(+)質粒中，構建重組質粒pcDNA3.1/lis。 通過脂質體法將其轉染人肝癌細胞系HepG2，進行G418篩選，獲得穩(wěn)定轉染的肝癌細胞系HepG2/lis，通過免疫熒光染色、RT-PCR和Western blot法鑒定lis在細胞中的表達; 采用Lambert法對細胞內lis酶的活性進行分析; 采用MTT法觀察穩(wěn)定轉染細胞系生長曲線，流式細胞儀分析細胞周期，裸鼠成瘤實驗分析其體內成瘤特性。結果 lis基因能穩(wěn)定整合于真核細胞中，并包裝出具備β-葡萄糖苷酶活性的蛋白。lis在細胞中的穩(wěn)定表達對細胞形態(tài)、生長特性、細胞周期、體內成瘤性等生物學特征并無明顯影響。 結論成功構建含lis基因的穩(wěn)定轉染肝癌細胞系，為將lis自殺基因系統(tǒng)應用于肝癌的治療提供了實驗基礎。
