Project description:miRNA profiling of bovine satellite cells (BSC) differentiated into myotubes (6th day of in vitro differentiation). BSC isolated from m. semitendinosus of beef (Hereford & Limousine) and dairy (Holstein-Friesian) cattle. Goal was to determine differences in miRNA expresion during in vitro myogenesis in beef vs dairy cattle used as a control.

Project description:The purpose of this research was to investigate the causes and consequences of pHu variations in beef cattle. For that, were evaluated 176 Nellore beef cattle, and classified into two different pHu groups: High (≥6.0, N=17) and Normal (<5.8, N=159). Plasma concentrations of cortisol and adrenocorticotropic hormone, lactate and glycogen muscular content, meat color, shear force and Longissimus thoracis muscle proteomic profile were evaluated and compared between pHu groups. Muscle glycogen content, meat color and shear force statistically differed between pHu groups. Label-free quantitative proteomic analysis revealed ten differentially abundant proteins between pHu groups, involved in metabolic processes and muscle contraction. Thirty-six and 31 proteins were exclusively present in Normal and High pHu group, respectively, which were related to TCA cycle, cortisol production, calcium regulation, and antioxidant function. The MYH7, UGP2, and VDAC3 were identified as potential indicators of pHu variations. CALM and NNT appeared to be interesting proteins to better understand the metabolic pathways behind pHu.

Project description:To evaluate how commonly-utilized antimicrobials affect the host transcriptome of commercial beef cattle overtime, we enrolled 105 feedlot beef steers randomly into seven different treatment groups (negative control, tulathromycin, tildipirosin, enrofloxacin, florfenicol, ceftiofur, oxytetracycline) to receive a one-time label dose of a commercial antimicrobial or not (negative control), and collected jugular whole blood into PAXgene RNA blood tubes at six time points: Day 0 (baseline), 3, 7, 14, 21, and 56.

Project description:Copy number variations (CNVs), which represent a significant source of genetic diversity in mammals, are currently being associated with phenotypes of clinical relevance, mostly in humans and mice. Notwithstanding, little is known about the extent of CNV that contributes to genetic variation in cattle. This study reports the highest resolution map of copy number variation in the cattle genome, with 304 CNV regions (CNVRs) being identified among the genomes of 20 bovine samples from 4 dairy and beef breeds. We used a set of NimbleGen CGH arrays that tile across the assayable portion of the cattle genome with approximately 6.3 million probes, at a 301 bp median probe spacing. These CNVRs covered 0.68% (23 Mb) of the genome, and ranged in size from 1.7 to 2,031 kb (median size 16.7 kb). About 20% of the CNVs colocalized with segmental duplications while 30% encompassed genes, mostly related with environmental response. About 10% of the orthologous CNV cow-human genes are related with human disease susceptibility and, hence, may have important phenotypic consequences. Together, this analysis provides a useful resource to assist with the assessment of CNVs in the contexts of bovine variation, health and productive efficiency. 20 samples were analyzed in a dye-swap loop design. In order to cover the latest bovine genome assembly (bt4) with high density, custom Nimblegen HD2 CGH arrays were planned in 3 designs. Each design covered a specific set of chromosomes with 2.1M probes, which yielded 420 bp of average probe spacing (301 bp median probe spacing).

Project description:In both beef and dairy cattle, the majority of embryo loss occurs in the first 14 days following insemination. During this period, the embryo is completely dependent on its maternal uterine environment for development, growth and ultimately survival, therefore an optimum uterine environment is critical to embryo survival. We used microarrays to assess endometrial gene expression in high and low fertility heifers during the mid-luteal phase of the estrous cycle.
