Project description:The expression of genes were analysed in 7th day of embryonic stage between Aseel, an indigenous slow-growing chicken, and control broiler, a fast-growing broiler chicken line. The whole embryo was collected in TRIZOL and total RNA was isolated. The expression profile of gene was determined in 64k Agilent chicken microarray chip. The Cy3 dye was used for detection. The fold change of expression was analysed in Aseel as compared to broiler chicken line.

Project description:Expression in Aseel (an indigenous chicken breed) as compared to broiler chicken in 7th and 18th days of embryonic stage
Project description:We characterized the seminal plasma proteome of eight Beijing-you (BJY) chickens, an indigenous chicken breed in China, differ in sperm motility.
Project description:Airway epithelial cells from 3 different breeds of chicken infected with Newcastle Disease virus were sequenced and compared to cells from uninfected control birds. The 3 breeds were an indigenous breed, commercial Rhode Island Reds and a hybrid breed (Kenbro).
Project description:CNV plays an important role in the chicken genomic studies,it is imperative need to investigate the extent and pattern of CNVs using array comparative genomic hybridization (aCGH) in chinese chicken breeds for future studies associating phenotype to genome architecture. we describe systematic and genome-wide analysis of CNVs loci in five Chinese indigenous chicken breeds were evaluated by aCGH. 5 Chinese native chicken were detected using ANKA broiler as reference.
Project description:Copy number variation profiles comparing control female Dehong chicken blood DNA with 3 different chicken breeds (white Leghorn, Cobb broiler, and Dou chicken) blood DNA. Each test breed had one male and one female sample, for a total of 6 test DNA samples. The goal is to determine the global copy number variation profiles between chicken breeds.
Project description:Climate change and disease have large negative impacts on poultry production, but little is known about the interactions of responses to these stressors in chickens. Fayoumi (heat and disease resistant) and broiler (heat and disease susceptible) chicken lines were stimulated at 22 days of age, using a 2x2x2 factorial design including: breed (Fayoumi or broiler), inflammatory stimulus [lipopolysaccharide (LPS) or saline], and temperature (35°C or 25°C). Transcriptional changes in spleens were analyzed using RNA-sequencing on the Illumina HiSeq 2500. Thirty-two individual cDNA libraries were sequenced (four per treatment) and an average of 22 million reads were generated per library. Stimulation with LPS induced more differentially expressed genes (DEG, log2 fold change ≥ 2 and FDR ≤ 0.05) in the broiler (N=283) than the Fayoumi (N=85), whereas heat treatment resulted in fewer DEG in broiler (N=22) compared to Fayoumi (N=107). The double stimulus of LPS+heat induced the largest numbers of changes in gene expression, for which broiler had 567 DEG and Fayoumi had 1471 DEG of which 399 were shared between breeds. Further analysis of DEG revealed pathways impacted by these stressors such as Remodelling of Epithelial Adherens Junctions due to heat stress, Granulocyte Adhesion and Diapedesis due to LPS, and Hepatic Fibrosis/Hepatic Stellate Cell Activation due to LPS+heat. The genes and pathways identified provide deeper understanding of the response to the applied stressors and may serve as biomarkers for genetic selection for heat and disease tolerant chickens.
