    • The present invention provides methods and compositions for generating novel nucleic acid molecules through targeted spliceosome mediated RNA trans-splicing that result in expression of an apoA-1 variant, the preferred embodiment referred to herein as the apoA-1 Milano variant. The compositions of the invention include pre-trans-splicing molecules (PTMs) designed to interact with a target precursor messenger RNA molecule (target pre-mRNA) and mediate a trans­-splicing reaction resulting in the generation of a novel chimeric RNA molecule (chimeric RNA) capable of encoding the apoA-1 Milano variant. The expression of this variant protein results in protection against vascular disorders resulting from plaque build up, i.e., strokes and heart attacks. In particular, the PTMs of the presént invention include those genetically engineered to interact with the apoA-1 target pre­mRNA so as to result in expression of the apoA-1 Milano variant. In addition, the PTMs of the invention include those genetically engineered to interact with the apoB or albumin or other specific target pre-mRNAs so as to result in expression of an apoB/apoA-1 and/or alb/apoA-1 wild type or Milano fusion protein thereby reducing apoB expression and simultaneously produce ApoA-1 function.
    • 本发明提供了通过靶向剪接体介导的RNA转接产生新的核酸分子的方法和组合物,其导致apoA-1变体(本文中称为apoA-1 Milano变体)的优选实施方案的表达。 本发明的组合物包括被设计成与靶前体信使RNA分子(靶前mRNA)相互作用并且介导导致产生新的嵌合RNA分子(嵌合体)的反式剪接反应的预转录分子(PTM) RNA)能够编码apoA-1 Milano变体。 该变体蛋白质的表达导致保护免受斑块积聚引起的血管疾病,即中风和心脏病发作。 特别地,预发明的PTM包括经遗传工程改造以与apoA-1靶preRNA相互作用以产生载脂蛋白-A 1米兰变体的表达的那些。 此外,本发明的PTM包括经遗传工程改造以与载脂蛋白B或白蛋白或其它特异性靶前体mRNA相互作用以产生apoB / apoA-1和/或alb / apoA-1野生型或 米诺融合蛋白从而降低apoB表达并同时产生ApoA-1功能。
