    • Compositions for targeted mutagenesis of cell surface receptors for HIV and methods of their use are provided herein. The compositions include triplex-forming molecules that bind to duplex DNA in a sequence specific manner at target sites to form triple-stranded structures. The triplex-forming molecules can be triplex-forming oligonucleotides (TFOs) or peptide nucleic acids (PNAs). The triplex-forming molecules are useful to induce site-specific homologous recombination in mammalian cells when used in combination with donor oligonucleotides. The triplex-forming molecules target sites within or adjacent to genes that encodes cell surface receptors for human immunodeficiency virus (HIV). This binding stimulates homologous recombination of a donor oligonucleotide to cause mutations in HIV cell surface receptor genes that result in one or more deficiencies in the ability of the encoded receptor to bind to HIV and allow its transport into the cell. Methods for ex vivo and in vivo prophylaxis and therapy of HIV infection using the disclosed compositions are also provided.
    • 本文提供了用于HIV的细胞表面受体的靶向诱变的组合物及其使用方法。 组合物包括在靶位点以序列特异性方式结合双链体DNA的三链体形成分子以形成三链结构。 三链体形成分子可以是三重复合形成寡核苷酸(TFO)或肽核酸(PNA)。 当与供体寡核苷酸组合使用时,三重形成分子可用于在哺乳动物细胞中诱导位点特异性同源重组。 三重形成分子靶向编码人免疫缺陷病毒(HIV)细胞表面受体的基因内或邻近的位点。 该结合刺激供体寡核苷酸的同源重组以引起HIV细胞表面受体基因中的突变,其导致编码的受体结合HIV并允许其转运到细胞中的能力的一个或多个缺陷。 还提供了使用所公开的组合物进行体外和体内预防和治疗HIV感染的方法。

    • Compositions containing molecules that bind to duplex DNA in a sequence-specific manner to form a triple-stranded structure are disclosed. Triplex-forming molecules facilitate strand displacement and triplex formation, referred to as a "clamp," in which one molecule binds to the target strand by Hoogsteen binding and the other molecule binds to the target strand by Watson-Crick binding in a sequence specific manner. A Watson- Crick binding "tail" added to the end of the Watson-Crick binding portion of the clamp increases the stringency of binding to the target duplex, improves the frequency of modification at the target site, and reduces the requirement for a polypurine:polypyrimidine stretch compared to triplex forming oligonucleotides (TFOs) or peptide nucleic acids (PNAs). When administered in combination with a donor oligonucleotide, triplex-forming molecules can enhance recombination of a donor oligonucleotide at the target site. Ex vivo and in vivo methods of gene correction in patients using the disclosed compositions are also disclosed.
    • 公开了含有以双链体DNA结合的分子的组合物,其以序列特异性方式形成三链结构。 三重形成分子促进链置换和三重形成,称为“钳夹”,其中一个分子通过Hoogsteen结合与靶链结合,另一个分子以序列特异性方式通过Watson-Crick结合结合靶链 。 在夹具的沃森 - 克里克结合部分末端添加的沃森 - 克里克结合“尾巴”增加了与目标双链体的结合的严格性,提高了靶位点修饰的频率,并降低了对于多巴胺的需求: 与三重形成寡核苷酸(TFO)或肽核酸(PNA)相比,聚嘧啶拉伸。 当与供体寡核苷酸组合施用时,三重形成分子可以增强靶位点处供体寡核苷酸的重组。 还公开了使用所公开的组合物的患者中基因校正的离体和体内方法。
