Description
The main objective of this study was to decipher the gene expression profile associated with the onset and early development of Wooden Breast Disease in commercial broiler chickens. To achieve this, pectoralis major muscle biopsy samples were harvested from high-breast-muscle-yield, purebred broiler line. The pectoral biopsy samples were collected from the cranial (week 2 and 3) and caudal (week 4) aspects of the muscle belly in birds which were allowed to grow up to 7 weeks of age. Three subsets of biopsy samples comprising 6 unaffected (U) and 10 affected (A) from week 2 and 4 and 4U and 12A from week 3 were processed for RNA-sequencing analysis. All selected samples were processed using Truseq stranded mRNA LT sample kit for paired-end 2x75-nucleotide sequencing with Illumina Hiseq 2500 sequencer.

Affymetrix Chicken Genome Array (chicken)
Description
Transgenerational effects of early experience on behavioural, hormonal and gene expression responses to acute stress in the precocial chicken. The data for the parental stressed and control birds is available in ArrayExpress with accession E-MTAB-924, while this experiment only concerns their offspring that never been exposed to early life stress.

Description
Expression profiling of sheep born to Australian industry sires with high and low genetic merit (Estimated Breeding Values or EBVs) for eye muscle depth (EMD). Progeny (40) from six Poll Dorset sires representing well defined extremes of EBVs for Eye Muscle Depth (low EBV EMD and high EBV EMD) were selected for analysis. The six sires were Australian industry sires with three sires representative of low EBV EMD and three representing high EBV EMD.

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.

Description
The ability to mature oocytes in vitro provides a tool for creating embryos by parthenogenesis, fertilization and cloning. Unfortunately the quality of oocytes matured in vitro falls behind that of in vivo matured oocytes. To address this difference transcriptional profiling by deep sequencing was conducted on pig oocytes that were either matured in vitro or in vivo. Alignment of over 18 million reads identified 1,316 transcripts that were differentially represented. One pathway that was overrepresented in the oocytes matured in vitro was for Wingless-type MMTV integration site (WNT) signaling. In an attempt to inhibit the WNT pathway Dickkopf-related protein 1 was added to the in vitro maturation medium. Addition of Dickkopf-related protein 1 improved the percentage of oocytes that matured to the metaphase II stage, increased the number of nuclei in the resulting blastocyst stage embryos, and in oocytes reduced the amount of disheveled segment polarity protein 1 protein. It is concluded that transcriptional profiling is a powerful method for detecting differences between in vitro and in vivo matured oocytes, and that the WNT signaling pathway is important for proper oocyte maturation.
