BackgroundPostnatal muscle growth is largely depending on the number and size of muscle fibers. The number of myofibers and to a large extent their metabolic and contractile properties, which also influence their size, are determined prenatally during the process of myogenesis. Hence identification of genes and their networks governing prenatal development of skeletal muscles will provide insight into the control of muscle growth and facilitate finding the source of its variation. So far most… Expand
Expression profiling of functional genes in prenatal skeletal muscle tissue in Duroc and Pietrain pigs.
TLDR
Eleven genes identified as differentially expressed in a previous microarray research and chosen for the function of the coded protein as putative candidate involved in myogenesis were considered to analyse their expression profile during foetal growth of Duroc and Pietrain pigs to provide new data on developmental changes of expression profile.

Comparative Analyses by Sequencing of Transcriptomes during Skeletal Muscle Development between Pig Breeds Differing in Muscle Growth Rate and Fatness
TLDR
A novel model in which MyoD and MEF2A controls the balance between intramuscular adipogenesis and myogenesis by regulating CEBP family is proposed, which contributes to elucidating the mechanism underlying muscle development, which could provide valuable information for pig meat quality improvement. Expand
Dynamic transcriptome profiles of postnatal porcine skeletal muscle growth and development
TLDR
A transcriptomic analysis of Longissimus dorsi muscle samples from Tibetan piglets at four postnatal stages revealed GO terms and pathways that could affect the postnatal muscle growth and development in piglets. Expand
Transcriptional Profiling Identifies Location-Specific and Breed-Specific Differentially Expressed Genes in Embryonic Myogenesis in Anas Platyrhynchos
TLDR
A comparative transcript analysis of the leg and pectoral muscles of two duck breeds improves the understanding of the location-specific and breed-specific genes and pathways but also provides some candidate molecular targets for increasing muscle products and meat quality by genetic control. Expand
Dynamic transcriptome profiles of skeletal muscle tissue across 11 developmental stages for both Tongcheng and Yorkshire pigs
TLDR
This study detected many functional genes and showed differences in the molecular mechanisms of skeletal muscle development between TC and YK pigs, providing a better understanding of skeletal Muscle developmental differences and valuable information for improving pork quality. Expand
Comparative transcriptomic analysis of skeletal muscle tissue during prenatal stages in Tongcheng and Yorkshire pig using RNA-seq
TLDR
Comprehensive high-resolution gene expression maps of these two pig breeds are constructed, which provides an in-depth understanding of the dynamics of transcriptional regulation during myogenesis, and would facilitate the elucidation of molecular mechanisms underlying myogenesis in the future studies.

Identification of genes related to skeletal muscle growth and development by integrated analysis of transcriptome and proteome in myostatin-edited Meishan pigs.
TLDR
An integrated analysis of transcriptome and proteome in longissimus dorsi muscle from myostatin wild type and MKO pigs on 65 days post coitus provided a new insight to further understanding of the molecular mechanisms by which growth and development are regulated in porcine skeletal muscle. Expand
Differential Transcriptome Analysis of Early Postnatal Developing Longissimus Dorsi Muscle from Two Pig Breeds Characterized in Divergent Myofiber Traits and Fatness
TLDR
The findings from this study can contribute to future investigations of skeletal muscle growth and development mechanism and to establishing molecular approaches to improve meat quality traits in pig breeding. Expand
The expression pattern of myogenic regulatory factors MyoD, Myf6 and Pax7 in postnatal porcine skeletal muscles.
TLDR
The results indicate that MyoD and Pax7 genes had higher expression levels in the early stages of development in both investigated breeds, and suggests that higher muscularity in Pietrain pigs is associated with the presence of a greater number of active satellite stem cells compared to other breeds.

Pre- and postnatal differential gene expression with relevance for meat and carcass traits in pigs − a review
TLDR
It is exemplarily discussed that differentially expressed transcript profiles of M. longissimus dorsi at prenatal and postnatal stages offer an insight into the biological processes in the live muscle that affect the process of meat maturation and finally meat quality. Expand

Transcriptome analysis of two bovine muscles during ontogenesis.
TLDR
The results reported here underline the importance of the last three months of gestation in muscle myogenesis, and highlight new genes involved in this process, to provide a first "bovine" muscle gene repertoire. Expand

TLDR
The results indicated that the expression of the myogenesis-related genes was greater in early Duroc embryos than in early Pietrain embryos, whereas the opposite was found in late embryos (63 to 91 d of gestation). Expand
Identification of genes that are differentially expressed in extraocular and limb muscle

The transcriptional profile of genes expressed in rat EOM versus limb muscle using a differential display strategy characterized the molecular mechanisms that specify the EOM-phenotype, and identified four genes that were novel, and have been named expressed in ocular muscle (eom) 1-4. Expand
Complementary DNA macroarray analyses of differential gene expression in porcine fetal and postnatal muscle.

Results indicate the switch in intermediate filament protein from vimentin to desmin occurs primarily at the level of transcription and/or RNA processing, and the methods used to identify differentially expressed genes may be conservative. Expand

The study revealed statistical-genetic evidence for association of the functional candidate genes with traits related to meat quality and muscle deposition and polymorphisms detected were identified that are in linkage disequilibrium with causal genetic variation within particular populations.

TLDR
The opportunities for manipulation of myogenesis in utero to improve adult performance are limited and the evidence indicates that the proportions of types of muscle fibre have a heritable component. Expand

Genetic variability and heritability of muscle fibre number and size are sufficiently high to include these traits in farm animal selection in addition to commonly used selection criteria for improving lean meat content and meat quality. Expand
