Project description:Purpose:We have used RNA-seq to examine of differentially expressed miRNAs in chicken leg muscle of three different development stages (11 embryo ages, 16 embryo ages, and 1 day old post hatch chick).The aims of this study are characterization of miRNAs differentially expressed in different developmental stage of chicken embryo, using RNA sequence sample. Methods: On this study we used two embryonic stage and one post hatch chick leg muscle of Xinghua chicken breed. Total RNA from E11 day embryo, E16 day embryo and 1 day post hatch chick was isolated by TRIzol following the manufacturer’s protocol (Invitrogen, CA, USA). Each stages were designed two samples, and the total samples were six (three group × two sample/group) and RNA samples of six individuals were pooled with equal amounts, and then were subjected to Illumina deep sequencing. Results: After eliminating adaptor and low-quality reads, a total of 5,302,700, 6,556,747, 5,359,793, 4,213,112, 7,112,885 and 7,469,939 clean reads were obtained in group E11 (E11.1-E11.2), group E16 (E16.1-E16.2) and group P1 (P1.1–P1.2) libraries, respectively. The clean reads were aligned to the chicken genome databases, miRBase, Rfam, RepBase and mRNA. Conclusions:To assess miRNA expression during chicken embryo skeletal muscle development, we sequenced and analyzed leg muscle at 11 day embryo age, 16 day embryo age, and 1 days post hatch.

Project description:In the current study, we expanded our previous work to identify miRNAs implicated in the myogenesis regulation through the comparison of miRNAs transcriptome in skeletal muscle tissues between broilers and layers. To address that, we firstly performed Solexa deep sequencing to profile miRNAs expressed in chicken skeletal muscle tissues. Sequence tags analyses not only enable us to report a group of highly abundant known miRNAs expressed in skeletal muscles but most importantly to identify novel putative chicken miRNAs from skeletal muscle tissue. Further miRNA transcriptome comparison and real-time RT-PCR validation experiments revealed seveal differentially expressed miRNAs between broilers and layers.

Project description:Abstract: Atmospheric ammonia is a common problem in poultry industry. High concentrations of aerial ammonia cause great harm to broilers' health and production. For the consideration of human health, the limit exposure concentration of ammonia in houses is set at 25 ppm. Previous reports have shown that 25 ppm is still detrimental to livestock, especially the gastrointestinal tract and respiratory tract, but the negative relationship between ammonia exposure and the tissue of breast muscle of broilers is still unknown. In the present study, 25 ppm ammonia in poultry houses was found to lower slaughter performance and breast yield. Then, high-throughput RNA sequencing was utilized to identify differentially expressed genes in breast muscle of broiler chickens exposed to high (25 ppm) or low (3 ppm) levels of atmospheric ammonia. The transcriptome analysis showed that 163 genes (fold change ≥ 2 or ≤ 0.5; P-value < 0.05) were differentially expressed between Ammonia25 (treatment group) and Ammonia3 (control group), including 96 down-regulated and 67 up-regulated genes. qRT-PCR analysis validated the transcriptomic results of RNA sequencing. Gene Ontology (GO) functional annotation analysis revealed potential genes, processes and pathways with putative involvement in growth and development inhibition of breast muscle in broilers caused by aerial ammonia exposure. This study facilitates understanding of the genetic architecture of the chicken breast muscle transcriptome, and has identified candidate genes for breast muscle response to atmospheric ammonia exposure.

Project description:To investigate specific miRNA expression profiles of Marek's disease virus (MDV)-infected samples, we performed deep sequencing for miRNAs in four small RNA libraries, including MDV-infected tumorous spleen, MD lymphoma from liver, and non-infected spleen and lymphocytes from controls. A total of 7.76x106, 6.36x106, 6.36x106, and 7.60x106 counts were obtained in four libraries, respectively. The sequences were blasted with chicken and MDV genomes and miRBase 16.0 to identify known and novel miRNAs. In total, 187 and 16 known mature miRNAs were identified in the chicken and MDV, respectively. Deep sequencing detected 942 novel chicken miRNA candidates, of which 646 were in tumorous spleen. These results indicate that MDV infection induced new host miRNA candidates and increased diversity of miRNAs. Of 942 miRNA candidates, 276 of 533 were verified by customized microarray, and 17 of them were further confirmed by qPCR.
