A strong relationship exists between increased inflammatory cytokines and muscle insulin resistance in obesity. This study focused on identifying a relationship between metabolic propensity and myostatin expression in muscle and spleen cells in response to high-fat diet intake. Using a comparative approach, we analyzed the effects of high-fat diet intake on myostatin and follistatin expression,...
Objective: Myostatin has recently been proposed as an important factor that not only regulates skeletal muscle mass, but also body fat mass. The aim of our study is to explore serum myostatin levels in overweight patients and its association with metabolic-related characteristics. Methods: 40 overweight patients and 40 normal weight controls were recruited, and serum myostatin were measured by ...
Follistatin is a functional antagonist of several members of the TGF-beta family of secreted signaling factors, including myostatin, the most powerful inhibitor of muscle growth characterized to date. Myostatin inhibition offers a novel therapeutic strategy for muscular dystrophy by restoring skeletal muscle mass and suppressing the progression of muscle degeneration. To assess the potential be...
recently, the role of myostatin (mstn) in controlling insulin resistance (ir( has been known. the aim of this study was to determine acute and delayed response of mstn and ir to circuit resistance exercise. for this purpose, 12 healthy men volunteered and participated in 2 sessions of the resistance exercise and control with one-week interval. after a session to instruct how to perform resistan...
Loss of muscle mass occurs in a variety of diseases, including cancer, chronic heart failure, aquired immunodeficiency syndrome, diabetes, and renal failure, often aggravating pathological progression. Preventing muscle wasting by promoting muscle growth has been proposed as a possible therapeutic approach. Myostatin is an important negative modulator of muscle growth during myogenesis, and myo...
Myostatin is a member of the transformating growth factor-beta (TGF-beta) superfamily of proteins and is produced almost exclusively in skeletal muscle tissue, where it is secreted and circulates as a serum protein. Myostatin acts as a negative regulator of muscle mass through the canonical SMAD2/3/4 signaling pathway. Naturally occurring myostatin mutants exhibit a 'double muscling' phenotype ...
Sarcopenia or loss of skeletal muscle mass is a major complication of cirrhosis and liver disease. A large body of literature exists to support the prognostic significance of sarcopenia in cirrhosis. Independent clinical consequences of sarcopenia in cirrhosis include lower survival and quality of life, increases risk of complications including infections and encephalopathy, and lower post live...
Myostatin is a negative regulator of muscle mass. The impact of myostatin deficiency on the contractile properties of healthy muscles has not been determined. We hypothesized that myostatin deficiency would increase the maximum tetanic force (P(o)), but decrease the specific P(o) (sP(o)) of muscles and increase the susceptibility to contraction-induced injury. The in vitro contractile propertie...
The effects of long-term physical inactivity on the expression of microRNAs involved in the regulation of skeletal muscle mass in humans are largely unknown. MicroRNAs are short, noncoding RNAs that fine-tune target expression through mRNA degradation or by inhibiting protein translation. Intronic to the slow, type I, muscle fiber type genes MYH7 and MYH7b, microRNA-208b and microRNA-499-5p are...
The present study determined the effects of concentric and eccentric muscle actions on the contents of serum myostatin and follistatin-like related gene (FLRG). Eight untrained males performed one exercise bout with each leg, separated by three weeks. One bout consisted of 7 sets of 10 repetitions of eccentric muscle actions of the knee extensors at 150% of the concentric 1-RM while the other b...
