    • The present invention provides compositions for RNA interference and methods of use thereof. In particular, the invention provides small hairpin RNAs (shRNAs) having modified promoters, including the Pol III U6 promoter, which may be used to increase the potency of shRNA by increasing the expression level. Modifications include constructs with a Pol II enhancer, such as the cytomegalovirus (CMV) enhancer, immediate-early promoter near the Pol III, e.g., U6 promoter, either upstream or downstream from the shRNA sequence and in either forward or backward orientation. Such constructs are useful for increasing the expression of the shRNA, thereby enhancing inhibition of a single nucleotide mismatched mutant allele. Functional and genomic and proteomic methods are featured. Therapeutic methods are also featured.
    • 本发明提供了用于RNA干扰的组合物及其使用方法。 特别地,本发明提供具有修饰的启动子的小发夹RNA(shRNA),其包括Pol III U6启动子,其可用于通过增加表达水平来增加shRNA的效力。 修饰包括具有Pol II增强子的构建体,例如巨细胞病毒(CMV)增强子,在Pol III附近的即时早期启动子,例如U6启动子,位于shRNA序列的上游或下游以及向前或向后的方向。 这种构建体可用于增加shRNA的表达,从而增强对单核苷酸错配突变体等位基因的抑制。 功能和基因组和蛋白质组学方法。 还介绍了治疗方法。

    • Human diseases caused by dominant, gain-of-function mutations develop in heterozygotes bearing one mutant and one wild-type copy of a gene. Because the wild­ type gene often performs important functions, whereas the mutant gene is toxic, any therapeutic strategy must selectively inhibit the mutant while retaining wild-type gene expression. The present invention includes methods of specifically inhibiting the expression of a mutant allele, while preserving the expression of a co-expressed wild­type allele using RNAi, a therapeutic strategy for treating genetic disorders associated with dominant, gain-of-function gene mutations. The invention also includes small interfering RNAs (siRNAs) and Small hairpin RNAs (shRNAs) that selectively suppress mutant, but not wild-type, expression of copper zinc superoxide dismutase (SOD1), which causes inherited amyotrophic lateral sclerosis (ALS).
    • 在具有一个基因的一个突变体和一个野生型拷贝的杂合子中,由显性增益功能突变引起的人类疾病发生。 因为野生型基因通常具有重要的功能,而突变基因是有毒的,任何治疗策略必须选择性地抑制突变体,同时保留野生型基因表达。 本发明包括特异性抑制突变等位基因表达的方法,同时使用RNAi保护共表达野生型等位基因的表达,用于治疗与显性功能获得功能基因突变相关的遗传疾病的治疗策略。 本发明还包括小干扰RNA(siRNA)和小发夹RNA(shRNA),其选择性地抑制引起遗传性肌萎缩性侧索硬化(ALS)的铜锌超氧化物歧化酶(SOD1)的突变体而不是野生型表达。
