Aspects of the disclosure relate to complexes comprising a muscle-targeting agent covalently linked to a molecular payload. In some embodiments, the muscle-targeting agent specifically binds to an internalizing cell surface receptor on muscle cells. In some embodiments, the molecular payload inhibits expression or activity of a DMPK allele comprising a disease-associated-repeat. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide or RNAi oligonucleotide.
摘要:
Nucleotide sequences including a micro-dystrophin gene are provided. The micro-dystrophin genes may be operatively linked to a regulatory cassette. Methods of treating a subject having, or at risk of developing, muscular dystrophy, sarcopenia, heart disease, or cachexia are also provided. The methods may include administering a pharmaceutical composition including the micro-dystrophin gene and a delivery vehicle to a subject. Further, the methods may include administering the pharmaceutical composition a subject having Duchenne muscular dystrophy or Becker muscular dystrophy.
摘要:
The present invention relates to RNA interference-based methods for inhibiting the expression of the myotilin gene. Recombinant adeno-associated viruses of the invention deliver DNAs encoding microRNAs that knock down the expression of myotilin. The methods have application in the treatment of muscular dystrophies such as Limb Girdle Muscular Dystrophy Type 1A.
摘要:
The present invention relates to an expression system for systemic administration comprising a sequence encoding a protein, said expression system allowing: the expression at a therapeutically acceptable level of the protein in the target tissues including skeletal muscles and/or the peripheral nervous tissue; and the expression at toxically acceptable level of the protein in tissues other than the target tissues, especially in the heart.
摘要:
In certain aspects, the present invention provides compositions and methods for inducing utrophin expression in muscle with an ActRIIB protein as therapy for muscular dystrophy. The present invention also provides methods of screening compounds that modulate activity of an ActRIIB protein and/or an ActRIIB ligand.

摘要:
The invention relates to meganuclease variants which cleave a DNA target sequence from the human dystrophin gene (DMD), to vectors encoding such variants, to a cell, an animal or a plant modified by such vectors and to the use of these meganuclease variants and products derived therefrom for genome therapy, ex vivo (gene cell therapy) and genome engineering including therapeutic applications and cell line engineering. The invention also relates to the use of meganuclease variants for inserting therapeutic transgenes other than DMD at the dystrophin gene locus, using this locus as a safe harbor locus. The invention also relates to the use of meganuclease variants for using the dystrophin gene locus as a landing pad to insert and express genes of interest.
