Among other things, the present disclosure provides oligonucleotides, compositions, and methods thereof. Among other things, the present disclosure encompasses the recognition that structural elements of oligonucleotides, such as base sequence, chemical modifications (e.g., modifications of sugar, base, and/or internucleotidic linkages) or patterns thereof, conjugation with additional chemical moieties, and/or stereochemistry [e.g., stereochemistry of backbone chiral centers (chiral internucleotidic linkages)], and/or patterns thereof, can have significant impact on oligonucleotide properties and activities, e.g., knockdown ability, stability, delivery, etc. In some embodiments, the oligonucleotides decrease the expression, activity and/or level of a C9orf72 gene, including but not limited to, one comprising a repeat expansion, or a gene product thereof. In some embodiments, the present disclosure provides methods for treatment of diseases using provided oligonucleotide compositions, for example, in treatment of C9orf72-related disorders.
本公开提供寡核苷酸、组合物及其方法等内容。本公开涵盖了对寡核苷酸的结构元素(如碱基序列、化学修饰(例如糖、碱基和/或核苷酸间连接的修饰)或其模式、与额外化学基团的结合以及/或立体化学[例如骨架手性中心的立体化学(手性核苷酸间连接)]及/或其模式等)的认识,这些因素可能对寡核苷酸的性质和活性(例如敲低能力、稳定性、传递等)产生重要影响。在某些实施例中,寡核苷酸降低C9orf72基因的表达、活性和/或水平,包括但不限于包含重复扩展或其基因产物的基因。在某些实施例中,本公开提供使用所提供的寡核苷酸组合物治疗疾病的方法,例如治疗C9orf72相关疾病。
