(Submitter supplied) We have analyzed immune chickens undergoing a secondary E. tenella infection using dual RNA-seq. Samples were taken from caecal tissue where the parasites replicate at six timepoints between 0 and 10 days post infection. The results that immune chickens have a much faster response to E. tenella compared to that of naïve chickens, and that there is a clear IFN-signature

(Submitter supplied) Abstract Background Chicken embryos emerge from their shell by the piercing movement of the hatching muscle. Although considered a key player during hatching, with activity that imposes a substantial metabolic demand, data are still limited. The study provides a bioenergetic and transcriptomic analyses during the pre-post-hatching period. Methods Weight and morphology alongside content determination of creatine and glycogen were analysed. more...

(Submitter supplied) Cell type repertoires have expanded extensively in metazoan animals, with some clade-specific cells being paramount to their evolutionary success. A prime example are the skeletogenic cells of vertebrates that form the basis of their developing endoskeletons. Depending on anatomical location, these cells originate from three different embryonic precursor lineages – the neural crest, the somites, and the lateral plate mesoderm – yet they converge developmentally towards similar cellular phenotypes. more...

(Submitter supplied) To indentify the master regulators that control the processes between the pre-recruitment and pre-ovulatory F5 follicular stages in laying hens. RNA was isolated from a group of 3-5 pre-recruitment follicles and the most recently recruiteed pre-ovualtory follicle (F5). After RNA isolation, follicles underwent RNA sequencing and differential gene expression analysis occurred.

(Submitter supplied) To investigate the difference between the pre-ovulatory F5 and pre-recruitment follicular stages in laying hens and identify master regulators that control the processes in these two follicular stages. RNA was isolated from a group of 3-5 pre-recruitment follicles and the most recently recruited pre-ovulatory follicle (F5). After RNA isolation, follicles underwent RNA sequencing and differential gene expression analysis occurred.

(Submitter supplied) Primordial germ cells (PGCs) are lineage restricted precursor cells of sperm and eggs. While avian PGCs from chicken can be cultured and modified to produce genome-edited chickens, the long-term culture of PGCs from other bird species has not been achieved. Here, we explored the effects of a cell-matrix interaction on the in vitro propagation of chicken PGCs. Blocking integrin signaling severely reduced the self-renewal of the PGC, indicating that a PGC-matrix interaction is an essential process for self-renewal. more...

(Submitter supplied) The histone variant H2A.Z is one of the most evolutionally conserved histone variants. Here, we identified a cancer-associated mutation in H2A.Z and evaluate the mutation. Structural and biochemical in vitro analyses showed that the H2A.Z mutation destabilizes nucleosome containing it. Then we applied the genetic complementation analysis to analyze cellular functions of the H2A.Z mutant. Although the H2A.Z mutant is deposited into nucleosome and rescues the lethality of H2A.Z DKO cells, the mutant does not complement mitotic defects of H2A.Z DKO cells, suggesting that stability of H2A.Z nucleosome is required for proper mitotic progression. more...

(Submitter supplied) The aim of this study was to explore whether, and if so, how Bacillus subtilis KC1 can enhance the growth performance of broilers that have been adversely affected by Mycoplasma gallisepticum (MG) infection. A total of 96 1-day-old male broilers were randomly divided into 4 groups: the control group (basal diet), the MG group (basal diet + MG challenge), the Bacillus subtilis KC1 group (basal diet + Bacillus subtilis KC1 supplementation), the Bacillus subtilis KC1 + MG group (basal diet + Bacillus subtilis KC1 supplementation + MG challenge). more...

(Submitter supplied) The histone variant H2A.Z is evolutionarily conserved from yeast to vertebrates. H2A.Z regulates gene expression when localized to promoter region. Recently, we identified two genes encoding H2A.Z, H2A.Z-1 and H2A.Z-2 in vertebrate genome. However, it is not clear that both H2A.Z-1 and H2A.Z-2 were required for the function of H2A.Z in gene regulation. To address this issue, we generated the H2A.Z-1 and H2A.Z-2 single knockout cells in chicken DT40 cells.We used microarrays to analysis the alternation of gene expression profiles in H2A.Z-1 KO and H2A.Z-2 KO cells and identify classes of up or down regulated gene by H2A.Z-1 and H2A.Z-2.

(Submitter supplied) In mice, genome-wide DNA methylation is actively erased at the onset of fertilisation, followed by remethylation in epiblasts after implantation, leading to inactive chromatin formation as a preliminary step to somatic cell differentiation, and then demethylation again during primitive streak formation and the determination of primordial germ cells (PGCs). This sequence of DNA methylation changes is accompanied by dynamic epigenetic reprogramming, including nuclear structure, histone modification, and intranuclear re-localisation of chromosomes, during totipotency acquisition of the fertilised egg and germline development. more...

(Submitter supplied) Chickens are the most abundant agricultural animals globally, with controlling abdominal fat deposition (AFD) being a key objective in poultry breeding. While GWAS can identify genetic variants associated with AFD traits, the precise roles and mechanisms of these variants remain largely unclear. This study used two distinct chicken lines, selectively bred for differing AFD, as experimental models. Through the integration of genomic, epigenomic, 3D genomic, and transcriptomic data, a comprehensive chromatin 3D regulatory network map was developed to reveal the genetic regulatory mechanisms that influence AFD traits. more...

Ingestion of paddy rice potentially affects on gastrointestinal physiology and function including digestion/absorption of nutrients and gut barrier function such as mucosal immunity, but the details of changes is unknown. To obtain insight into the physiological modifications in the small intestine of chickens fed paddy rice, we conducted a comprehensive analysis of gene expression in small intestine by DNA microarray. more...

(Submitter supplied) Neurocristopathies such as CHARGE syndrome result from aberrant neural crest development. A large proportion of CHARGE cases are attributed to pathogenic variants in the gene encoding CHD7, chromodomain helicase DNA binding protein 7, which remodels chromatin. While the role for CHD7 in neural crest development is well documented, how this factor is specifically upregulated in neural crest cells is not understood. more...
