The myostatin gene of seven important meat (Beltex (Australia), Beltex×Huyang (F1), Meat and Multi-Prolific Chinese Merino Fine Wool, Meat Chinese Merino Fine Wool and Dorper (South Africa)) and non-meat (Huyang and Kazak) sheep breeds was analyzed to study the genetic basis of muscular hypertrophy (double muscling) phenotype in sheep. SNPs, four in regulatory regions and several in the introns...
Molecular biology has enabled the identification of the mechanisms whereby inactive myostatin increases skeletal muscle growth in double-muscled (DM) animals. Myostatin is a secreted growth differentiation factor belonging to the transforming growth factor-β superfamily. Mutations make the myostatin gene inactive, resulting in muscle hypertrophy. The relationship between the different character...
Quantitative trait loci (QTL) for fat deposition, growth and muscling traits have been previously mapped on the basis of low-density linkage maps in a wild boar x Meishan F2family to the chromosome X region flanked by SW2456 and SW1943. Improved QTL resolution was possible using data for F2 animals with a marker density of 2.7 cM distance in the SW2456 to SW1943 region, including AR, SERPINA7 a...
Beef cattle have been selected in particular for increased growth rates and greater muscle development. The myostatin gene is responsible for the muscle hyperplasia in double muscled animals and it is also responsible in these animals for differences, during foetal development, in the relative proportions of muscle fibre types. A mutation in the myostatin gene in Limousin cattle (F94L) has been...
Double muscling is a trait previously described in several mammalian species including cattle and sheep and is caused by mutations in the myostatin (MSTN) gene (previously referred to as GDF8). Here we describe a new mutation in MSTN found in the whippet dog breed that results in a double-muscled phenotype known as the "bully" whippet. Individuals with this phenotype carry two copies of a two-b...
FOR RELATED ARTICLE, SEE PAGE 1212For three decades, OSA therapy has primarily been nocturnal CPAP, which, although mostly effective, is limited by poor long-term compliance. An alternative, more recent approach hypoglossal nerve stimulation (HGNS), aimed at activating upper airway muscle activity to maintain pharyngeal patency during sleep. HGNS younger, less obese, carefully selected subjects...
