Affymetrix Bovine Genome Array (bovine)
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.

Illumina HiSeq 2500
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.

Description
Changes in gene expression during berry development during a grape growing season were analysed. The effect on gene expression of different viticultural practises during grape berry development was investigated in this study by comparing two irrigation methods (standard versus prolonged deficit irrigation).

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
ZnO and TiO2 nanoparticles can elicit a range of perturbed cell responses in vitro. Exposure to topically applied sunscreens containing ZnO or TiO2 particles may or may not elicit a biological effect in mice. We aimed to compare the biological responses of immune-competent hairless mice receiving topical applications of commercially available sunscreens with or without metal oxide nanoparticles, with the responses of mice receiving no sunscreen.
Publication Title
Long-term exposure to commercially available sunscreens containing nanoparticles of TiO2 and ZnO revealed no biological impact in a hairless mouse model.
