Project description:Herein we present spatialtemporal profiles and performed a detailed data analysis in longissimum dorsi muscle of Chinese merino sheep at embryonic ages D85, D105, and D135. This is the first report of myogenic differentiaion and muscle fibre formation at the whole transcriptome level. The objective herein was to evaluate the whole transcriptome profiles and to develop an indepth and systematic understanding of molecular genetic controls underlying myofibre proliferation and differentiation in sheep. This report provides an effective reference for the study of non-coding RNA in other agricultural animals.

Project description:Texel and Ujumqin sheep show obvious differences in muscle and fat growth, so they are ideal models not only to understand the molecular mechanism in prenatal skeletal muscle development, but to identify the potential target genes of myostatin. To elucidate the phenotypic variation between the two sheep breeds and the dynamic characteristics of gene expression in skeletal muscle during the development, we examined the development of skeletal muscle in transcriptome-wide level at 70, 85,100,120 , 135 days post coitus (dpc),birth, 1 month and 2 month. Using the specialized and standardized sheep transcriptome-wide oligo DNA microarray (Agilent), we analyzed the transcriptomic profiles of longissmuss dorsi muscle from fetuses of Texel and Ujumqin sheep. We characterized dynamic transcriptome-wide profiles that accompany the prenatal skeletal muscle and fat development in Texel and Ujumqin sheep respectively, and compared the difference in profiles of gene expression between the two sheep breeds at the same developmental stage.Some potential myostatin target genes and other genes controlling the growth of skeletal muscle and adipose were identified for further examinations. Our findings not only contribute to understand the molecular mechanism of prenatal skeletal muscle development in large precocial species, but also provide some clues for human myopathy and obesity at prenatal stages. Moreover, we also can identify putative candidate genes for meat quality traits in farm animals.

Longissimus dorsi muscles were sampled from five prenatal development stages (70, 85, 100, 120 and 135 day of gestation) in Texel and eight development stages (at 70, 85, 100, 120, 135 days post coitus (dpc), birth, 1 month and 2 month) in Ujumqin sheep. There were at least three replicates at each development time in each breed. Two gene expression experiments were conducted with a total of 40 hybridizations.

Project description:Lots of genes which regulate the proliferation and differentiation of sheep skeletal muscle are targets of microRNAs, so it is important that investigate the microRNA profile in sheep skeletal muscle to further understand the function of these genes. In this experiment, we used microarray to detect 364 miRNAs in sheep skeletal muscle and detemine the miRNAs that express at a high level in it.

Project description:Expression data from Sheep longissimus dorsi (LD) muscle during development; fetal lambs (80, 100, 120 days gestation), new born lambs at birth (150 d) and lambs at 12 weeks (230 d) The fetal to neonatal developmental transition corresponds with profound changes in skeletal muscle function as it adapts to the new physiological demands of locomotion and postural support against gravity. The mechanisms underpinning this adaption process are unclear but are likely to be initiated by changes in hormone levels occurring during the major developmental transition. We tested the hypothesis that this period is associated with changes in the transcription of skeletal muscle genes, particularly genes involved in oxidative metabolism. Using an ovine model, transcriptional profiling was performed on longissimus dorsi skeletal muscle taken at three fetal developmental time points (80, 100 and 120 d of fetal development) as well as two postnatal time points, one within 3 days after birth and a second at 12 weeks of age. The developmental time course was dominated by large changes in the expression of 2471 genes during the period from late fetal development (120 d fetal development) to birth (within 1-3 days of birth). Analysis of the functions of the genes that were uniquely up-regulated in this period showed strong enrichment for oxidative metabolism and the TCA cycle indicating enhanced mitochondrial activity. Indeed, histological examination of tissues from these developmental time points directly demonstrated a marked increase in mitochondrial activity between the late fetal and early post-natal samples. The genes that were down-regulated in this period suggested de-emphasis of an array of biological functions including Wnt signaling, cell adhesion and differentiation. There were also changes in the expression of genes prior to this late fetal â postnatal transition and between the two postnatal time points that involved a variety of biological functions. It is concluded that there is substantial and coordinated changes in the transcription of a large number of genes in skeletal muscle which underpin the adaption of muscle to the new physiological demands in the postnatal environment. Microarrays were used for transcription profiling of skeletal muscle samples taken from fetal lambs (80, 100, 120 days gestation), new born lambs at birth (150 d) and lambs at 12 weeks (230 d) Sheep used in this experiment were bred from a research flock of Dorset/Suffolk/Rambouillet cross-bred sheep raised at Utah State University and cared for and euthanased for sample collection in accordance with the animal ethics guidelines of Utah State University (Utah, USA). Longissimus dorsi (LD) skeletal muscle samples were taken from fetal lambs at 80, 100 and 120 days of gestation, new born lambs within 1 to 3 days of birth (i.e. 150 days of development) and young lambs at 12 weeks of age (230 days of development). Three individuals were sampled at each developmental time

Project description:BackgroundDNA methylation is an epigenetic regulatory form that plays an important role in regulating the gene expression and the tissues development.. However, DNA methylation regulators involved in sheep muscle development remain unclear. To explore the functional importance of genome-scale DNA methylation during sheep muscle growth, this study systematically investigated the genome-wide DNA methylation profiles at key stages of Hu sheep developmental (fetus and adult) using deep whole-genome bisulfite sequencing (WGBS).ResultsOur study found that the expression levels of DNA methyltransferase (DNMT)-related genes were lower in fetal muscle than in the muscle of adults. The methylation levels in the CG context were higher than those in the CHG and CHH contexts, and methylation levels were highest in introns, followed by exons and downstream regions. Subsequently, we identified 48,491, 17, and 135 differentially methylated regions (DMRs) in the CG, CHG, and CHH sequence contexts and 11,522 differentially methylated genes (DMGs). The results of bisulfite sequencing PCR (BSP) correlated well with the WGBS-Seq data. Moreover, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional annotation analysis revealed that some DMGs were involved in regulating skeletal muscle development and fatty acid metabolism. By combining the WGBS-Seq and previous RNA-Seq data, a total of 159 overlap genes were obtained between differentially expressed genes (DEGs) and DMGs (FPKM > 10 and fold change > 4). Finally, we found that 9 DMGs were likely to be involved in muscle growth and metabolism of Hu sheep.ConclusionsWe systemically studied the global DNA methylation patterns of fetal and adult muscle development in Hu sheep, which provided new insights into a better understanding of the epigenetic regulation of sheep muscle development.
