154 results about "Myostatin" patented technology

Myostatin (also known as growth differentiation factor 8, abbreviated GDF-8) is a myokine, a protein produced and released by myocytes that acts on muscle cells' autocrine function to inhibit myogenesis: muscle cell growth and differentiation. In humans it is encoded by the MSTN gene. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family.

Oligomers

Certain disclosed oligomers induce exon skipping during processing of myostatin pre-mRNA. The oligomers may be in a vector or encoded by the vector. The vector is used for inducing exon skipping during processing of myostatin pre-mRNA. A therapeutically effective amount of the oligomer may be administered to a subject patient such that exon skipping during processing of myostatin pre-mRNA is induced. The administration to a subject may be used in order to increase or maintain muscle mass, or slowing degeneration of muscle mass in the subject. The administration to a subject may ameliorate muscle wasting conditions, such as muscular dystrophy. Examples of such muscular dystrophies which may be so treated include Becker's muscular dystrophy, congenital muscular dystrophy, Duchenne muscular dystrophy, distal muscular dystrophy, Emery-Dreifuss muscular dystrophy, facioscapulohumeral muscular dystrophy (FSHD), limb-girdle muscular dystrophy, myotonic muscular dystrophy, and oculopharyngeal muscular dystrophy

CRISPER-Cas9-system-mediated sheep MSTN (myostatin) gene knock-out and exogenous gene site-specific integration method

The invention relates to a CRISPER-Cas9-system-mediated sheep MSTN (myostatin) gene knock-out and exogenous gene site-specific integration method. The method comprises the following steps: establishing a CRISPER-Cas9-system-based gRNA (guide ribonucleic acid) expression vector according to a sheep MSTN gene sequence, establishing an exogenous-gene-containing donor plasmid capable of being integrated into a host genome according to the acting site of the gRNA, and transforming the optimized CRISPER-Cas9 vector, the gRNA expression vector and the linearized donor plasmid into sheep fibroblasts, thereby obtaining the sheep MSTN gene knock-out and exogenous gene site-specific integrated cells. The CRISPER-Cas9-mediated targeted vector provides a simple quick safe way for sheep MSTN gene knock-out and exogenous gene site-specific integration, thereby greatly enhancing the screening efficiency of the transgenic cell line. The method can screen the site-specific integrated exogenous gene cell line without adding any selection marker, thereby greatly enhancing the safety of the transgenic animals and having important value for sheep genetic breeding.
