Project description:We report the application of single-molecule-based sequencing technology for high-throughput profiling of miRNAs in goat muscle tissue.We identified 1120 miRNAs in fetus and lamb muscle tissue; 895 were known miRNAs and 313 were novel miRNAs. According to analysis, 192 miRNAs were up-regulated in fetus samples compared to lamb samples, while 121 miRNAs were down-regulated.To confirmed stage-specific differences in the abundance of certain miRNAs, we focused on the most up-regulated miRNA and found to be predominantly expressed in lamb muscle tissue, suggesting a potential role in muscle development.It has become a molecular marker for breeding programs of mutton production.
Project description:To explore functional lncRNAs during sheep muscle growth, we systematically investigated lncRNAs using strand-specific Ribo-Zero RNA Sequencing at three key developmental stages of Hu sheep (110-day fetus, 5-day-old lamb and 2-year-old adult)
Project description:Comparsion of proteomes of Campylobacter fetus subsp. fetus to compare protein level via iBAQ analysis, expression (by LFQ) and coverage between Campylobacter fetus subsp. fetus strain82-40 vs Campylobacter fetus subsp. fetus strain ATCC 27374
Project description:Cistus ladanifer L. is a common shrub endemic to the Mediterranean that is highly concentrated in condensed tannins (CT). CT form complexes with dietary protein that resist microbial degradation in the rumen, which enhances dietary protein utilization in ruminant diets. The objective of this study was to evaluate the utilization of CT in the diet of lambs on the proteomes of muscle, hepatic and adipose tissues. Twenty-four white merino ram lambs were divided in three groups (n=8) fed on different diets: control (16% crude protein - CP), reduced protein (12% CP) and reduced protein treated with CT extract. At the end of the trial, lambs were slaughtered and the longissimus lumborum muscle, hepatic and peri-renal adipose tissues sampled. A two-way approach was used for shotgun proteomic analysis: 2D-DIGE (gel-based) and nanoLC-MS (gel-free). In the muscle, control lambs had lower abundance proteins that partake in the glycolysis pathway. With dietary 12 % CP, lambs had higher abundance of Fe-carrying proteins in the hepatic tissue. Lambs with dietary CT had higher abundance of hepatic flavin reductase. In the adipose tissue, control lambs had lower abundance of fatty-acid synthase. In conclusion, CT inclusion influences specific pathways in lamb tissues.
Project description:To explore functional circRNAs during goat muscle development, we systematically investigated the circRNAs profiles using high throughput transcriptome sequencing technology (RNA-seq) at key developmental stages of fetus and Kid in Haimen goat.
