肌球蛋白重链(MHC)等肌节蛋白的显性突变是导致人类肥厚型心肌病(HCM)和扩张型心肌病(DCM)的主要遗传原因。在这里,我们证明了HCM心脏MHC基因(Myh 6)R403 Q突变在小鼠中的表达可以选择性地沉默由腺相关病毒载体提供的RNAi盒。RNAi转导的MHC 403/+小鼠没有肥厚或心肌纤维化,HCM的病理表现至少6个月。由于HCM的抑制仅通过突变体转录物水平降低25%来实现,因此我们认为HCM患者的可变临床表型反映了等位基因特异性表达,并且突变体转录物的部分沉默可能具有治疗益处。
Dominant mutations in sarcomere proteins such as the myosin heavy chains (MHC) are the leading genetic causes of human hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). Here we demonstrate that expression of the HCM cardiac MHC gene (Myh6) R403Q mutation in mice can be selectively silenced by an RNAi cassette delivered by an adeno-associated virus vector. RNAi-transduced MHC403/+ mice had neither hypertrophy or myocardial fibrosis, the pathologic manifestations of HCM for at least 6 months. As inhibition of HCM was achieved by only a 25% reduction in the levels of the mutant transcripts, we suggest that the variable clinical phenotype in HCM patients reflects allelic-specific expression and that partial silencing of mutant transcripts may have therapeutic benefit.
