Abstract
  癌症是目前人類的十大死因之一,人類為了治療癌症做了許多嚐試。其中,反譯寡核苷酸( Oligonucleotides , ODN )在癌症治療方面是令人感興趣的。反譯寡核苷酸是一種antisense藥物 ,可借由阻斷某些基因表現的轉錄或轉譯來達到抑制蛋白質合成,進而達到治療的目的。
  但是這些antisense藥物,包含反譯寡核苷酸,在體內中容易被核酸酶所破壞。也因為其表面帶有負電性,使得被攝入細胞膜內有些困難。所以選定合適的載體是antisense藥物的首要目標。為了增加細胞膜的穿透率及對特定細胞的標靶性,本研究針對微脂粒此種劑型以及其修飾方式進行更進一步探討。
  本實驗中所使用的微脂粒由DC-Chol/egg-PC/PEG-DSPE 以22.5:76:1.5 mol%組成,其粒徑大小平均為201.5±15.97 nm,其包覆ODN 的能力約為75.5%,表面電荷為16±3.5mV,粒子之膠體安定性可達8週。為了使其具有標靶特性,在微脂粒表面利用運鐵蛋白當作配位體 ( ligand ) 經後嵌入法修飾。
  另一方面,本實驗利用鐵螯合物(desferoxamine, DFO)使細胞的鐵缺乏,進而增加細胞表面運鐵蛋白(transferrin)受體的表現。在實驗中,我們利用給予細胞0, 5, 10 µg/ml的DFO來比較在第5, 8, 11, 14天的細胞表面運鐵蛋白受體的表現。接著投予Free ODN,G3139 ( 1µM,3µM ) 的G3139微脂粒以及經過運鐵蛋白修飾後的G3139微脂粒( 1µM,3µM ),並比較以上不同給藥方式對BCL-2表現造成的影響。
