(Submitter supplied) In the present study, we examined the hepatic transcriptome of chickens during the peri-hatch period—or the metabolic jump from chorioallantoic (embryo) to pulmonary (hatchling) respiration. Although our major interest was comparison of differentially-expressed genes between embryos and hatchlings, we made pairwise contrasts across six developmental ages. We collected the liver from four embryos at three ages (e16, e18 and e20) and four hatchling chicks at three ages (1, 3 and 9 days) post hatching. more...

(Submitter supplied) This study integrates global transcriptional profiling and the metabolic perturbation induced by fasting and re-feeding. Genetic control of growth and development should be revealed by systematic modeling of metabolic and regulatory pathways. Chicken oligo arrays were used for transcriptional profiling in two time-course experiments. Two critical developmental stages were chosen: immediately after hatchling (Wk1) and prior to marketing of broiler chickens (Wk6). more...

(Submitter supplied) We performed gene expression profiling on chicken livers at five important embryonic developmental stages (E7, E12, E14, E17 and E21), which were selected from chicken lines with significant differences in abdominal fat content. Each developmental stage had its unique gene expression pattern and stage-specific differentially expressed genes (DEGs). Furthermore, the three rapid growth periods (E12, E14 and E17) had similar expression patterns. more...

(Submitter supplied) This study aimed to identify key genes and pathways related to essential functions of riboflavin during the development of chicken embryos. We used as a unique model a strain of mutant chickens (rd/rd) which is unable to produce a riboflavin-binding protein and lays riboflavin-deficient eggs in which the embryos suddenly die between 13 and 15 days of incubation (e13 and e15, respectively). In these embryos, the diminished activity of flavin-dependent enzymes, particularly those associated with β-oxidation of fatty acid, limits the catabolism of yolk lipids that normally serve as the predominant source of energy required for growth. more...

(Submitter supplied) Chickens divergently selected for either high growth (HG genotype) or low growth (LG genotype) at SRA-INRA, France were used to profile abdominal adipose gene expression at 7 wk of age. The HG and LG chickens are different in various phenotypic and metabolic measurements, including growth rate, abdominal fat, plasma glycemia, insulinemia, T4, T3, triglyceride and NEFA. The HG and LG chickens are valuable as a model for biomedical and agricultural traits. more...

(Submitter supplied) Chickens divergently selected for either high growth (HG genotype) or low growth (LG genotype) by F.H. Ricard at SRA-INRA, Nouzilly France were used for time-course transcriptional profiling of abdominal fat during juvenile development (1 to 11 weeks of age) to identify differentially expressed genes. The HG and LG chickens are different in various phenotypic and metabolic measurements, including growth rate, abdominal fat, plasma glycemia, insulinemia, T4, T3, triglyceride and NEFA. more...

(Submitter supplied) In this study, RNA-Seq technology was adopted to investigate the differences in expression profiles of the hepatic lipid metabolism-related genes and the associated pathways between juvenile and laying hens. RNA-Seq analysis was carried out to estimate total RNA harvested from the liver of juvenile hens (n = 3) and laying hens (n = 3). Compared with juvenile hens, 2574 differentially expressed (DE) genes (1487 down and 1087 up) with P ≤ 0.05 were obtained, and 955 of these genes were significantly DE (SDE) at a false discovery rate (FDR) of 0.05 and fold-change ≥ 2 in laying hens. more...

(Submitter supplied) Four weeks old male broilers, fed ad libitum or fasted for 16h or 48h were used to describe the evolution of global gene expression profiles in chicken liver during a 48h fasting period using a chicken 20K oligo array. Among the 20460 oligos on the microarray, 13057 were identified as aligning with a unique coding region of the 2.1 Washington University assembly of the chicken sequence genome. So the statistical analyses were performed on this 13057 gene set. more...

(Submitter supplied) Meat type chickens have limited capacities to cope with high environmental temperatures, sometimes leading to important mortality in farms and subsequent economic loss. One of the strategies to increase the sustainability of broiler chicken production is to enhance their adaptive capacities to face heat exposure using heat conditioning (C) during embryogenesis. This strategy was shown to improve thermotolerance in later life. more...

(Submitter supplied) Temporal changes in the embryo transcriptome between the blastocyst stage (Day 7) and initiation of elongation (Day 13) differ between in vivo- and in vitro-derived embryos and are reflective of subsequent developmental fate. The aim of this study was to examine the temporal changes in transcriptional profile as the embryo develops from a spherical blastocyst on Day 7 to an ovoid conceptus at the initiation of elongation on Day 13 and to highlight differences in these temporal gene expression dynamics between in vivo- and in vitro-derived blastocysts which may be associated with embryonic survival/mortality using the bovine Affymetrix microarray.

(Submitter supplied) The ductus arteriosus constricts after birth or hatching and eventually closes to terminate embryonic circulation. Chicken embryos have two long ductus arteriosus. Then the pulmonary artery-sided and descending aorta-sided ductus arteriosus have distinct functional characteristics, such as oxygen responsiveness. We used microarrays to elucidate the difference between the pulmonary artery-sided and descending aorta-sided ductus arteriosus in their transcriptional profiles.

(Submitter supplied) The mature eye lens contains a surface layer of epithelial cells called the lens epithelium that require a functional mitochondrial population to maintain the homeostasis and transparency of the entire lens. The lens epithelium overlies a core of terminally differentiated fiber cells that must degrade their mitochondria to achieve lens transparency. These distinct mitochondrial populations make the lens a useful model system to identify those genes that regulate the balance between mitochondrial homeostasis and elimination. more...
