Using stable isotope tracer methodologies and mass spectrometric detection, we observed: (a) 76-92-year-old physically frail and 62-74-year-old middle-age adults have lower mixed muscle protein synthetic rates than 20-32-year-old men and women; (b) 2 weeks and 3 months of weightlifting exercise increased the synthetic rate of myosin heavy chain (MHC) and mixed muscle proteins to a similar magnitude in frail, middle-age, and young women and men; (c) Serum myostatin-immunoreactive protein levels were elevated in physically frail women and were inversely correlated with lean mass.

Ablating myostatin (Mstn) prevents obesity, so we investigated if Mstn deficiency could improve insulin sensitivity.

Improvements to muscle and liver insulin sensitivity (approximately 200-400%) correlated with 50-75% decreased tumor necrosis factor (TNF)alpha production and coincided with severe Mstn deficiency.

Short-term treatment of Mstn(Ln/Ln) mice with recombinant Mstn led to increased plasma TNFalpha and insulin resistance.

Myostatin (Mstn) and growth/differentiation factor 11 (Gdf11) are highly related transforming growth factor beta (TGFbeta) family members that play important roles in regulating embryonic development and adult tissue homeostasis.

Loss of Mstn in mice causes a doubling of skeletal muscle mass while loss of Gdf11 in mice causes dramatic anterior homeotic transformations of the axial skeleton, kidney agenesis, and an increase in progenitor cell number in several tissues.

After the study, ADMA, sFas, myostatin, insulin resistance, high-sensitive C-reactive protein (hsCRP), estimated glomerular filtration rate (eGFR), blood pressure and proteinuria levels were decreased, and FMD and serum albumin levels increased (P < 0.05 for all).

In this study, we determined whether Mstn disruption could prevent the development of insulin resistance, proatherogenic dyslipidemia, and atherogenesis.

The effects of high-fat/high-cholesterol diet on body composition, plasma lipids, systemic and tissue-specific insulin sensitivity, hepatic steatosis, as well as aortic atheromatous lesion were characterized in Mstn(-/-)/Ldlr(-/-) mice in comparison with control Mstn(+/+)/Ldlr(-/-) mice.

Inactivation of Mstn protects against the development of insulin resistance, proatherogenic dyslipidemia, and aortic atherogenesis in Ldlr(-/-) mice.

Actvin and myostatin bind to activin type II receptors (ActRIIA and ActRIIB), and the glycine-serine-rich domains of type I receptors are phosphorylated by type II receptors.

Animal studies in vivo indicate that leptin treatment in extremely leptin-sensitive ob/ob mice reduces body weight exclusively by reducing fat mass and that it increases muscle mass by downregulating myostatin expression.

Leptin administration reversed cortisol response (P < 0.01) but failed to alter activin A, follistatin, or myostatin concentrations.
