The myostatin (MSTN) gene was studied as a candidate genetic marker for growth traits. We investigated polymorphisms of the MSTN gene in 664 individuals from four goat populations and applied PCR-SSCP and DNA sequencing analysis to reveal two single nucleotide polymorphisms (DQ167575: g.368A>C (p.Lys49Thr) and g.4911C>T. At g.368A>C locus, the frequencies of g.368A allele were 0.75–0.81, and th...
Growth and differentiation factor (GDF) 11 is a member of the transforming growth factor β superfamily recently identified as a potential therapeutic for age-related cardiac and skeletal muscle decrements, despite high homology to myostatin (Mstn), a potent negative regulator of muscle mass. Though several reports have refuted these data, the in vivo effects of GDF11 on skeletal muscle mass hav...
Mutations in the myostatin (MSTN) gene can inactivate its expression and result in a non-functional protein, which leads to dramatic muscularity and a "double-muscling" phenomenon in many species. Using gene sequencing and polymerase chain reaction-single-strand conformation polymorphism methods, polymorphisms of the MSTN gene were investigated as a candidate marker for growth in 288 goats. The...
Myostatin (MSTN) is a negative regulator of myogenesis in vertebrates. Depletion of mstn resulted in elevated muscle growth in several animal species. However, the report on the complete ablation of mstn in teleost fish has not yet become available. In this study, two independent mstnb-deficient mutant lines in zebrafish were generated with the TALENs technique. In the mstnb-deficient zebrafish...
The Lys(K)153Arg(R) polymorphism in exon 2 (rs1805086, 2379 A>G replacement) of the myostatin (MSTN) gene is a candidate to influence skeletal muscle phenotypes. We examined the association between the MSTN K153R polymorphism and 'explosive' leg power, assessed during sprint (30 m) and stationary jumping tests [squat (SJ) and counter-movement jumps (CMJ)] in non-athletic young adults (Universit...
the aim of this study was to investigate the effects of an acute bout of exhaustive resistance exercise on the expression of myogenesis modulators (myostatin (mstn) and myod) in male trained and untrained wistar rats’ fast and slow muscles. thirty rats were assigned to three groups: control (n=6), untrained (n=12) and trained (n=12). resistance exercise (weight lifting up a vertical ladder) was...
Knockout mice lacking myostatin (Mstn), a negative regulator of the growth of skeletal muscle, develop significant increases in the relative mass of masticatory muscles as well as the ability to generate higher maximal muscle forces. Wild-type and Mstn-deficient mice were compared to investigate the postnatal influence of elevated masticatory loads due to increased jaw-adductor and bite forces ...
The present study was conducted on the Nile tilapia (Oreochromis niloticus) and screened for single nucleotide polymorphisms (SNPs) in muscle hormone genes myogenin (MyoG) myostatin (MSTN). Samples were collected from JangHang fish farm categorized by body weight sex. average total 1.02 kg 82 males 0.63 70 females. A range of ±10% considered as normal weight. Target regions each gene categorize...
in the present study, the polymorphism of myostatin gene (mstn) in native chickens of western azerbaijan rearing and breeding institute was investigated. the blood samples were collected from eighty two randomly selected hens. genomic dna was extracted from blood samples and a fragment of myostatin including 599 bp in promoter and exon 1 was amplified using pcr method. breeding values for body ...
