Obesity and insulin resistance cause serious consequences to human health. To study effects of skeletal muscle growth on obesity prevention, we focused on a key gene of skeletal muscle named myostatin, which plays an inhibitory role in muscle growth and development. We generated transgenic mice through muscle-specific expression of the cDNA sequence (5'-region 886 nucleotides) encoding for the ...
Myostatin (Mstn) participates in the regulation of skeletal muscle size and has emerged as a regulator of muscle metabolism. Here, we hypothesized that lack of myostatin profoundly depresses oxidative phosphorylation-dependent muscle function. Toward this end, we explored Mstn(-/-) mice as a model for the constitutive absence of myostatin and AAV-mediated overexpression of myostatin propeptide ...
In this study, we produced a polyclonal antibody against unprocessed chicken myostatin and examined the effect of in ovo administration of the antibody on posthatch chicken growth and muscle mass. A PCR-amplified unprocessed chicken myostatin cDNA was cloned into an Escherichia coli expression vector, and myostatin proteins were expressed. Recombinant myostatin purified by electro-elution of th...
Myostatin (growth and differentiation factor-8) is a member of the transforming growth factor-beta superfamily, is expressed mainly in skeletal muscle and acts as a negative growth regulator. Mature myostatin (C-terminal) is a homodimer that is cleaved post-translationally from the precursor myostatin, also yielding the N-terminal prodomain. We expressed in Escherichia coli three forms of fish ...
Myostatin is a member of the transforming growth factor (TGF)-beta superfamily, known for its ability to inhibit muscle growth. It can also regulate metabolism and glucose uptake in a number of tissues. To determine the mechanism of myostatin's effect on glucose uptake, we evaluated its actions using choriocarcinoma cell lines that are widely used as models for placental cells. Protein and mRNA...
Myostatin, a member of the transforming growth factor-beta superfamily, is a negative regulator of skeletal muscle growth and development. Myostatin inhibition leads to increased skeletal muscle mass in mammals; hence, myostatin is considered a potential therapeutic target for skeletal muscle wasting. However, downstream molecules of myostatin in the skeletal muscle have not been fully elucidat...
Muscle wasting is common in advanced heart failure. Myostatin is an important modulator of muscle catabolism. We measured serum levels of myostatin and its propeptide in patients with chronic heart failure and analyzed their relationships with clinical parameters and prognosis. The study included 70 patients: 30 in New York Heart Association (NYHA) functional class I-II and 40 in class III-IV. ...
Previous findings have provided strong evidence that myostatin functions as a negative regulator of muscle mass during development and growth. In the present study, we test the hypothesis that myostatin may serve a similar function in fully differentiated muscle experiencing modified loading. Our findings show that myostatin expression can be modulated in fully differentiated, nonpathological s...
BACKGROUND Myostatin is a muscle derived factor that functions as a negative regulator of skeletal muscle growth. Induction of myostatin expression was observed in rodent models of muscle wasting and in cachectic patients with cancer or pulmonary disease. Therefore, there is an increasing interest to use serum myostatin as a biomarker. METHODS We established an immunoradiometric sandwich assa...
