Expression profiling in ductus arteriosus and aorta of Brown-Norway and Fischer344 rats

ABSTRACT: Comparison of gene expression levels in ductus arteriosus (DA) and aorta in full-term (21 days) neonates of Brown-Norway (BN) and Fischer344 (F344) rats We analyzed the fold difference between BN and F344 rats in ductus arteriosus in order to identify the down-regulated and up-regulated genes specifically in BN rat's DA. The differences in aorta was also examined for additional comparison. Total RNA was extracted from aorta and DA tissues from BN and F344 rat neonates one hour after delivery, and converted to biotin-labeled cRNAs that were hybridized to Affymetrix Rat Gene 1.0 ST Array.

Transcriptional profiles in the chicken ductus arteriosus during hatching

Project description: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.

Expression profiling in perinatal Ductus Arteriosus (DA) and Aorta (Ao).

Project description:Compared the gene expression profiles of two contiguous vessels pre and post - birth, namely the Ductus Arteriosus (DA), committed to become a fibrous ligament, and the Aorta (Ao), which conversely takes on a permanent activity. The effect of artificially enhanced O2 tension was analyzed in DA in the pre-birth condition. Keywords: Comparison gene expression

Transcription profiling of rat aorta and ductus arteriosus

Project description:The transcriptional profiles of the aorta and the ductus arteriosus during development were compared. Experiment Overall Design: Total RNA samples were isolated from pooled tissues obtained from Wister rat embryos on embryonic day 19 and 21, and from neonates on the day of birth (n>=120). The RNA was converted to biotin-labeled cRNA, which was hybridized to Affymetrix RG_U34A microarray. The hybridization experiments were performed in duplicate.

Gene Profiling in Mouse Fetal Ductus Arteriosus

Project description:The ductus arteriosus (DA) is a fetal vascular shunt that is located between the main pulmonary artery and the aorta. Oxygenated fetal blood from the placenta is shunted past the uninflated fetal lungs, crosses the DA, and is then available to the peripheral organs. In utero closure of the DA is deleterious, but postnatal closure of the DA is necessary for establishment of pulmonary circulation and the transition to newborn life. We used microarrays to compare ductus arteriosis (DA) and aortic gene expression at a single time point (day 19 of gestation, which is the day of expected delivery). DA and corresponding aortic vascular segments from fetal mice on day 19 of gestation were collected from every pup in a litter (up to the first 10 pups). These samples were pooled and considered representative of the DA's or aortas from one pregnant female. Tissues were homogenized via 27g needle, per GentraSystems Versagene kit

Expression data from endthelial cells in ductus arteriosus and aorta in rat fetuses or neonates

Project description:Endothelial cells (Ecs) lining the blood vessels have been known to have a variety of functions and play a central role in homeostasis of the circulatory system. Since ductus arteriosus (DA) has unique characteristics comparing other vessels, we hypothesized that ECs were the primary target to investigate the molecular mechanisms of DA-specific vasoconstriction and vascular remodeling. Using fluorescence activated cell sorter, we isolated ECs from pooled tissues from the DA or the aorta of Wistar rat fetuses on the 21st day of gestation (e21) or 30 minutes after birth (day0). We prepared 3 sets of ECs in each tissues and time points. We aimed to compare the gene profiles of DA and the aorta at each developmental stage.
