Myostatin expression
WebMyostatin (MSTN), a negative regulator of muscle mass, is reported to be increased in conditions linked with muscle atrophy, sarcopenia, and other muscle-related diseases. Most pharmacologic approaches that treat muscle disorders are ineffective, emphasizing the emergence of MSTN inhibition. In this study, we used computational screening to uncover … WebMyostatin, also known as growth differentiation factor 8 (GDF-8), is an extracellular cytokine abundantly expressed in skeletal muscles and in small amounts in the myocardium, that …
Myostatin expression
Did you know?
WebMyostatin is a member of the transforming growth factor (TGF)-β superfamily. It is expressed by animal and human skeletal muscle cells where it limits muscle growth and promotes protein breakdown. Its effects are influenced by complex mechanisms including transcriptional and epigenetic regulation and modulation by extracellular binding proteins. WebBriefly, the pET protein expression system (Novagen) was used to express and purify recombinant myostatin. Bovine myostatin cDNA (amino acids 267–375) was PCR amplified and cloned into the pET 16-B vector (Novagen) in-frame with the 10 histidine residues.
WebMyostatin protein was seen in most but not all, of the nuclei of polynucleated fibers expressing MHC-II, and myostatin was detected in the cytoplasm of myotube. The localization of myostatin protein in myotube nuclei was confirmed by Western blot of isolated nuclear and cytoplasmic fractions. WebSep 9, 2003 · Myostatin expression was further confirmed in Pax7-positive satellite cells by in situ hybridization (Fig. 1, C and D). In addition, purified satellite cells appear to express myostatin mRNA and protein, confirming that Myostatin is present in satellite cells.
