Project description:The callipyge mutation causes postnatal muscle hypertrophy in heterozygous lambs that inherit a paternal callipyge allele (+/CLPG). Our hypothesis was that the up-regulation of one or both of the affected paternally expressed genes (DLK1 or PEG11) initiates changes in biochemical and physiological pathways in skeletal muscle to induce hypertrophy. The goal of this study was to identify changes in gene expression during the onset of muscle hypertrophy in order to identify the pathways that are involved in the expression of the callipyge phenotype. Gene expression was analyzed in longissimus dorsi total RNA from lambs at 10, 20, and 30 days of age using the Affymetrix Bovine Expression Array. Keywords: time course

Experiment Overall Design: Longissimus dorsi were collected from 10, 20, and 30 day old callipyge and normal lambs with 2 biological replicates for each group. Total RNA was isolated and hybridized to Affymetrix Bovine Expression arrays. Data were analyzed in SAS and all genotype effects were followed up by qPCR in 42 lambs ranging from 10 to 200 days of age.

Project description:Longissimus muscle samples were collected from lambs at 4 developmental time points (prenatal gestational d 85 and 133, and postnatal d 42 and 243). Muscle samples were examined to determine the impact of myofiber hypertrophy on the mRNA profile.

Project description:Longissimus muscle samples were collected from lambs at 6 developmental time points (prenatal gestational d 85, 110, 133, and postnatal d 42, 65, and 243). Muscle samples were examined to determine the impact of myofiber hypertrophy on the miRNA profile.

Project description:Infection of sheep with Brucella ovis results in ovine brucellosis, a disease characterized by infertility in rams, abortion in ewes and increased perinatal mortality in lambs. During the course of the infection both the ovine immune response and host cell gene expression are modified. The objective of this research was to conduct a preliminary characterization of differential gene expression in rams experimentally infected with B. ovis by microarray hybridization and real-time RT-PCR.

Project description:Expression data from Sheep longissimus dorsi (LD) muscle during development
| PRJNA124243 | ENA
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
