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 existence of conventional dendritic cells (cDCs) has not yet been demonstrated outside mammals. In this paper, we identified bona fide cDCs in chicken spleen. Comparative profiling of global and of immune response gene expression, morphology, and T cell activation properties show that cDCs and macrophages (MPs) exist as distinct mononuclear phagocytes in chicken, resembling their human and mouse cell counterparts. Using computational analysis, core gene expression signatures for cDCs, MPs, T and B cells across chicken, human and mouse were established, which will facilitate the identification of these subsets in other vertebrates. Overall this study, by extending the newly uncovered cDC and MP paradigm to chicken, suggests that the generation of these two phagocyte lineages occurred before the reptile to mammal and bird transition in evolution. It opens avenues for the design of new vaccines and neutraceuticals that are mandatory for the sustained supply of poultry products in the expanding human population.

Project description:We report the transcriptomes of 10 different chicken (Gallus gallus) cell/tissue types. The goal of this project was to determine similarities and differences between different cell/tissue types, with respect to protein coding genes, lncRNA, isoform counts, and differential gene expression. We provide raw data and bigWig files for UCSC visualization. The findings described here will be useful towards a complete annotation of chicken tissue and cellular transcriptomes.

Project description:Ma-Huang chicken as a high-quality broiler is one of the most popular chickens in the frozen chicken market. However, some chicken may instead have white or lighter skin, which directly causes economic losses every year. To obtain better insight into the molecular mechanisms associated with the process of pigmentation of yellow-skinned broilers reared under intensive conditions, a total of six-hundred Ma-Huang chickens was randomly selected in a single slaughterhouse, the color measurements were carried out on both cloaca(alive) and five different part after slaughtering adopting the L* a* b* system and using a 3nh-NH310 colorimeter, color values from areas of the chicken skin pear each image automatically retrieved by MATLAB, production and slaughtering traits were also measured, comparative transcriptomic analysis of high yellowness(s_deep) versus low yellowness(s_light) skin was performed using the Illumina Hiseq 4000. Average values of the cloaca(alive), cloaca (hair removal), thigh, shank and abdominal fat were 8.98, 7.66, 2.62, 7.29 and 12.86, respectively. The better production and slaughtering traits were observed in higher skin yellowness chicken. Yellowness values of the cloaca(alive) and after slaughtering were significantly correlated (p < 0.05), suggesting that the color of after slaughtering evaluation may be carried out on cloaca(alive). A total of 19061 unigenes were assembled from the reads obtained from the skin of two groups, 882 unigenes were differentially expressed between s_deep and s_light (Fold change ≥ 2, Adjusted P <= 0.001), 612 that up-regulated and 270 that down-regulated genes in s_deep skin, as compared with s_light skin. Twelve promising candidate genes may play an important role in the pigmentation of chicken skin, i.e. GPR143, PMEL, TYR, CYP11A1, TECRL, ACACB, TLR2B, ALDH1A3, FHL2, TECRL, DUOX2, SMOC1 were included. Furthermore, some important functional pathways were revealed, such as the biological process, cellular component and molecular function, which appear to be much activity in skin pigmentation. Our data provide a valuable resource for identifying genes whose functions are critical to skin pigmentation, facilitate understanding the molecular mechanisms of the skin color variation on yellow-skinned broiler chickens under commercial conditions, accelerate the molecular selection of the specific strain on consistent skin colors which allow reduction in pigment use to achieve the skin acceptance by the consumer.

Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 8,413 nuclei in chicken adult testis. This dataset includes two samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.

We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds. Infected, uninfected chicken cecal epithelia and merozoites were selected for RNA extraction and hybridization with Affymetrix microarrays. Our goal was to analyze global transcriptome changes in chicken cecal mucous membranes in response to E. tenella infection in vivo. We used infected (T1,T2,T3; three biological replicates) and uninfected (Neg1, Neg2, Neg3; three biological replicates) samples to identify genes that were differentially expressed. Meanwhile, RNA and probes were also prepared from parasite merozoites (Mzt) from infected samples (Mzt) and used as an additional control in microarray hybridization.

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.
