Abstract
微小核糖核酸,是一個小片段髮夾型之RNA,內生性的存在於動植物以及病毒基因體中。微小核醣核酸在細胞中是由 RNA聚合脢II 所轉錄出來的,並經由 Drosha, Dicer 和RISC複合體的作用, 最後成為長度約為 22 核苷酸長的有功能性的寡核醣核酸。微小核糖核酸在體內藉由抑制轉譯或是 mRNA 的降解,來負調控下游基因的表現。有研究指出許多微小核醣核酸之下游基因的功能是調控細胞的生長、分化或是凋亡。
大多數的癌症死亡的主要原因是因為腫瘤轉移。而最近的研究顯示,微小核糖核酸在惡性腫瘤:如乳腺癌,肝癌,前列腺癌和大腸癌的侵襲和轉移扮演了重要的角色。本研究利用高通量生物晶片資料,結合有轉移能力的惡性腫瘤、與不會轉移的良性腫瘤,子宮內膜異位到卵巢的細胞、與正常的子宮內膜細胞找出促癌轉移基因與抑制癌轉移基因,後續利用生物資訊方式分析出它們的上游 microRNA,以及隱藏的下游microRNA, 希望未來可以進一步應用在臨床癌症治療上,降低病患死亡率。
