This invention relates to methods and compositions for selectively reactivating or downregulating certain genes, e.g., genes regulated by zinc-finger protein CCCTC-binding factor (CTCF) on autosomes (e.g., imprinted genes, tumor suppressors, cancer) and the inactive X chromosome (Xi), e.g., genes associated with X-linked diseases, e.g., Rett Syndrome, Factor VIII or IX deficiency, Fragile X Syndrome, Duchenne muscular dystrophy, and PNH, in heterozygous females carrying a mutated allele, in addition to a functional wildtype or hypomorphic allele.
本发明涉及选择性地重新激活或下调某些基因的方法和组合物,例如受常染色体上锌指蛋白CCCTC结合因子(CTCF)调控的基因(如印记基因、肿瘤抑制因子、癌症)和无活性X染色体(Xi),如与X连锁疾病(如雷特综合征、因子VIII或IX缺乏症、脆性X综合征、杜氏肌营养不良症和PNN)相关的基因、在携带突变等位基因的杂合子雌性体内,除了功能性野生型或低形变等位基因外,还可发现与 X 连锁疾病(如雷特综合征、因子 VIII 或 IX 缺乏症、脆性 X 综合征、杜氏肌营养不良症和 PNH)相关的基因。
