(Submitter supplied) Birds have a sex chromosome system in which females are heterogametic (ZW) and males are homogametic (ZZ). The differentiation of avian sex chromosomes from ancestral autosomes entailed the loss of most genes from the W chromosome during evolution. However, to what extent mechanisms evolved that counterbalance the consequences of this extensive gene dosage reduction in female birds has remained unclear. more...

(Submitter supplied) To investigate the transcriptional regulation network of thesuppression of ILTV infection by PP1 and PP2 in chickenLMH cells, we treated LMH cells with PP1 or PP2 upon ILTV infection. We then performed gene expression profiling analysis using data obtained from RNA-seq of LMH cells.

(Submitter supplied) Three-dimensional organization of mitotic chromosomes is established by cohesin and condensin complexes. In the centromere, cohesin maintains sister chromatid pairing until anaphase onset, while condensin provides elastic resistance to spindle forces. However, how condensin and cohesin structure vertebrate centromeres remains unclear. By super-resolution imaging, Capture-C analysis and polymer modeling we show that vertebrate centromeres are partitioned into two condensin-dependent subdomains during mitosis. more...

(Submitter supplied) Neurocristopathies such as CHARGE syndrome result from aberrant neural crest development. A large proportion of CHARGE cases are attributed topathogenic variantsin the gene encoding CHD7, chromodomain helicase DNA binding protein 7, which remodels chromatin. While the role for CHD743in neural crest development is well documented,how this factor is specifically upregulated in neural crest cells is not understood. more...

(Submitter supplied) Background: MYCN gene is a transcription factor whose amplification and overexpression can lead to tumorigenesis. In retina, MYCN overexpression is related to tumorigenesis of retinoblastoma, a childhood cancer. Purpose: To find out differentially expressed genes in MYCN-overexpressing cells, which will give information of MYCN-related gene expression and possibly find out new pathways in mechanism of retinoblastoma tumorigenesis with MYCN overexpression. more...

(Submitter supplied) Formalin induces inter- and intra-molecular crosslinks within exposed cells. This cross-linking can be exploited to characterise chromatin state as in the MNase (micrococcal nuclease) assays. Our team aims to optimise these assays for application in museum preserved formalin-exposed specimens. To do so, we applied an optimised MNase assay to fresh-frozen and archival eastern water dragon specimens, as old as 1905. more...

(Submitter supplied) Eimeria (E.) maxima parasite infects the midgut disrupting the jejunal and ileal mucosal lining causing high morbidity and mortality in chickens. Heat stress (HS) is a seasonal stressor that affects biological functions leading to poor performance. Our objective was to elucidate how HS, E. maxima infection, and their combination affect the ileum transcriptome. Two-hundred and forty 2-week-old males Ross708 chickens were randomly allocated into four treatment groups: thermoneutral control (TNc), thermoneutral infected (TNi), heat stress control (HSc), and heat stress infected (HSi), with 6 replicates each of 10 birds. more...

(Submitter supplied) Species difference in susceptibility to toxicants is a critical issue in ecotoxicology. Transcriptomics is being proposed as a strategy to improve toxicity testing for regulatory risk assessment; however, different responses among species have not been extensively explored using this approach. In the present study, we identified dysregulated genes and pathways in Japanese quail (JQ) and double-crested cormorant (DCCO) embryos following exposure to ethinylestradiol (EE2). more...

(Submitter supplied) Hindbrain boundary cells of st. 18 HH chick embryo express the ECM molecule Chondrotin sulphate proteoglycan (CSPG). To determine whether the ventricular zone of hindbrain boundaries act as reservoirs of NPSCs, we separated between hindbrain boundary cells and the rest of hindbrain cells based on the expression pattern of CSPG which seemed membrane-bound. FACS approach was used to isolate CSPG-positive cells and CSPG-negative cells. more...

(Submitter supplied) The immune system is a complex infrastructure where many cells interact with each other and perform duties depending on their type and function. When using traditional immunological methods in studying non-traditional model organisms, such as birds, challenges arise. These are often associated with a lack of knowledge surrounding the organism in question—particularly, the expected leukocytes, their cell-specific marker genes, and associated reagents. more...

(Submitter supplied) Many animals exhibit typical color patterns that have been linked to key adaptive functions, yet the developmental mechanisms establishing these crucial designs remain unclear. Here, we surveyed color distribution in the plumage across a large number of passerine finches. Despite extreme apparent pattern diversity, we identified a small set of conserved color regions whose combinatory association can explain all observed patterns. more...

Unfortunately, the heritable characteristics of HVP are not yet fully understood. Motivated by poultry industry demand, we deployed multi-omics comparing the clinical HVP and normal samples profiling the potential regulating molecular landscape in cell and genome resolution, specifically, aiming to decipher the precise molecular genomic marker. more...
