Project description:Transcriptional profiling of the jejunum mucosa with 1.5 fold-change reporter genes in comparing control black-boned chickens under normal temperature (NT) conditon with heat-stress treated black-boned chickens under high temperature (HT) condition. Goal was to determine the differentially expressed genes (DEGs) in co-family black-boned chickens exposure to heat stress based on global chicken gene expression. Two-condition experiment, HT vs. NT Treatment. Biological replicates: 3 control replicates, 3 heat stressed replicates.

Project description:The aim of the present study was to investigated the difference of Nrf2-regulated genes in livers between normal and heat-stressed chickens. The CUT&Tag and high-throughput sequencing technologies were used in this experiment. Results showed that 13171838- 15417444 clean reads were obtained in this study. These data suggested that there were many Nrf2- regulated genes in the liver of heat-stressed chicken.

Project description:To realize the gene expression in response to acute heat stress in chicken small yellow follicles, we have employed whole genome microarray expression profiling as we have employed whole genome microarray expression profiling as a tool to identify genes response to acute heat stress. Female B strain Taiwan country chickens were subjected to acute heat stress (38℃) for 2 h, and then exposed to 25℃, with small yellow follicles collected 0, 2, and 6 h after the cessation of heat stress, using non heat-stressed hens as a control group (n = 3 hens per group). Based on a chicken 44K oligo microarray, 69, 51, and 76 genes were upregulated and 58, 15, 56 genes were downregulated after heat treatment of H2R0, H2R2, and H2R6, respectively, using a cutoff value of two-fold or higher in the small yellow follicles of the heat-stressed chickens from those of the control chickens. Upregulation of heat shock protein 25, interleukin 6, metallopeptidase 1, and metalloproteinase 13, and downregulation of type II alpha 1 collagen, discoidin domain receptor tyrosine kinase 2, and Kruppel-like factor 2 were confirmed through quantitative real-time polymerase chain reaction (qRT-PCR).

Project description:To realize the gene expression in response to acute heat stress in chicken testis, we have employed whole genome microarray expression profiling as we have employed whole genome microarray expression profiling as a tool to identify genes response to acute heat stress. Male B strain Taiwan country chickens were subjected to acute heat stress (38℃) for 4 h, and then exposed to 25℃, with testes collected 0, 2, and 6 h after the cessation of heat stress, using non heat-stressed roosters as a control group (n = 3 roosters per group). Based on a chicken 44K oligo microarray, 163 genes significantly differed in the testes of the heat-stressed chickens from those of the control chickens. The mRNA expressions of upregulated genes, including HSP25, HSP90AA1, HSPA2, and LPAR2, and downregulated genes, including CDH5, CTNNA3, EHF, CIRBP, SLA, and NTF3, were confirmed through quantitative real-time polymerase chain reaction (qRT-PCR).

Project description:Relative expression levels of mRNAs in chicken cecal epithelia experimentally infected with Eimeria tenella were measured at 4.5 days post-infection. Two weeks old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of Eimeria tenella. Cecal epithelia samples were collected from >12 birds in infected or uninfected group at 4.5 d following infections, in which samples from 4 birds were pooled together to form a total 3 biological replicates in each group. Parasite merozoites were also collected from four infected chickens at 5 d after infections. Uninfected control samples, merozoites and infection group samples were selected for RNA extraction and hybridization on Affymetrix microarrays. We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds.

Project description:The genetic foundation of chicken tail feather color is not very well studied to date, though that of body feather color is extensively explored. In the present study, we used a synthetic chicken dwarf line (DW), which was originated from the hybrids between a black tail chicken breed, Rhode Island Red (RIR) and a white tail breed, Dwarf Layer (DL), to understand the genetic rules of the white/black tail color. The DW line still contain the individuals with black or white tails, even if the body feather are predominantly red, after more than ten generation of self-crossing and being selected for the body feather color. We firstly performed four crosses using the DW line chickens including black tail male to female, reciprocal crosses between the black and white, and white male to female to elucidate the inheritance pattern of the white/black tail. We found that (i) the white/black tail feather colors are independent of body feather color and (ii) the phenotype are autosomal simple trait and (iii) the white are dominant to the black in the DW lines. Furtherly, we performed a genome-wide association (GWA) analysis to determine the candidate genomic regions underlying the tail feather color by using black tail chickens from the RIR and DW chickens and white individuals from DW lines.

Project description:This work was to study the transcriptome profiles in the skin of chickens with black versus white skin using high-throughput RNA deep-sequencing technology, to investigate the different expression profiles of the genes involved in skin pigmentation, then look for the main differences between black and white skin colors in Lueyang chickens. 16-week-old white and black female Lueyang chickens (5 birds per color) were selected for the sample collection. A piece of skin (8 mm in diameter) from the left back was collected . Total RNA was extracted from the sample using Trizol reagent . Three RNA samples from either the black or white skin samples were pooled following mRNA isolation. The sequencing of the library was performed using an Illumina HiSeq 2000 (LianChuan Sciences, Hangzhou, China). According the result of sequencing, some colored gene expressions were validated using Real time quantitative polymerase chain reaction (qPCR).
