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:Archive with all the variants detected within the sheep transcriptome. Transcriptome sequencing (RNA-seq) was performed on total RNA extracted from longissimus dorsi muscle, perinephric fat and tailed fat. The experiment was performed in 3 Lanzhou fat-tailed sheep, 3 Small Tail Han sheep and 3 Tibetan sheep, which differ in their tail traits. The project Coordinator is Lin Ma from Northwest A&F University, China.

Project description:To investigate the impact of adding succinate to the diet on the production performance, meat quality, muscle fiber characteristics, and transcriptome of the longissimus dorsi muscle in Tan sheep, 36 Tan sheep were selected and fed with different levels of succinate (0%, 0.5%, 1.0%, 2.0%) for a 60-day trial period. Overall, compared to the control group, the addition of succinate to the diet improved the production performance, slaughter performance, and meat quality of Tan sheep. It significantly increased dry matter intake, carcass weight, eye muscle area, and the GR value while significantly reducing the shear force and cooking loss of the longissimus dorsi muscle (p<0.05). Furthermore, the addition of succinate to the diet altered the muscle fiber characteristics of the longissimus dorsi muscle in Tan sheep, significantly increasing the fiber diameter and cross-sectional area of type I and type IIa muscle fibers (p<0.05). The addition of 1.0% succinate to the diet altered the transcriptome of the longissimus dorsi muscle in Tan sheep, with 741 differentially expressed genes identified compared to the control group. These differentially expressed genes were involved in various pathways related to lipid metabolism, energy metabolism, and muscle development, such as insulin secretion, insulin resistance, cAMP signaling pathway, PI3K-Akt signaling pathway, and FoxO signaling, among others. In summary, succinate plays a crucial role in regulating energy metabolism, protein deposition, and glucose and lipid metabolism homeostasis in Tan sheep through insulin signaling pathways and the interaction of muscle cell factors. By modulating the expression of relevant genes, succinate improves the muscle fiber characteristics of Tan sheep, thereby enhancing production performance and meat quality.

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:Mear prodution is the most important trait for sheep. In this study, we performed a Genome-wide association study (GWAS) by using Illumina Ovine SNP50 BeadChip in 329 purebred sheep phenotyped for 11 growth and meat production traits (birth weight, weaning weight, 6-month weight, eye muscle area, fat thickness, pre-weaning gain, post-weaning gain, daily weight gain, height at withers , chest girth and shin circumference). A total of 319 sheep and 48,198 SNPs were fitted using TASSEL 3.0 software as random effects in a mixed linear model. 36 chromosome-wise significant SNPs were identified for 7 traits and 10 of them reached genome-wide significance level consistently for post-weaning gain. Gene annotation was implemented based on the latest version3.1 ovine genome sequence (released October 2012), and meanwhile we referenced genomic information of human, bovine, mouse and rat. More than one-third SNPs (14 out of 36) were located within ovine genes , some other were located close to ovine genes (878bp-398165bp apart).

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:The ovine Callipyge mutation causes postnatal muscle hypertrophy localized to the pelvic limbs and torso, as well as body leanness. The mechanism underpinning enhanced muscle mass is unclear, as is the systemic impact of the mutation. Using muscle fibre typing immunohistochemistry we confirmed muscle specific effects and demonstrated that affected muscles had greater prevalence and hypertrophy of type 2X fast twitch glycolytic fibres and decreased representation of types 1, 2C, 2A and/or 2AX fibres. To investigate potential systemic effects of the mutation, proton NMR spectra of plasma taken from lambs at 8 and 12 weeks of age were measured. Multivariate statistical analysis of plasma metabolite profiles demonstrated effects of development and genotype but not gender. Plasma from Callipyge lambs at 12 weeks of age, but not 8 weeks, was characterized by a metabolic profile consistent with contributions from the affected hypertrophic fast twitch glycolytic muscle fibres. Microarray analysis of the perirenal adipose tissue depot did not reveal a transcriptional effect of the mutation in this tissue. We conclude that there is an indirect systemic effect of the Callipyge mutation in skeletal muscle in the form of changes of blood metabolites, which may contribute to secondary phenotypes such as body leanness. Microarrays were used for transcription profiling of kidney fat samples taken from Callipyge (n=4) and wild type (n=4) lambs at 12 weeks of age. 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). Kidney fat (KF) samples were taken from lambs at 12 weeks of age; four callipyge (CN) genotype animals and four normal (NN) genotype animals were compared.
