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 del...

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 w...

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 t...

Patent ductus arteriosus (PDA) is the third most common congenital heart disease and resulted from the persistence of ductal patency after birth. Ductus arteriosus closure involves functional and structural remodeling, controlled by many factors. The closure-related human plasma proteins are unknown...

The effects of retinoic acid/vitamin A signal on the transcriptional profile of the ductus arteriosus during development were examined. 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 th...

Closure or patency of the ductus arteriosus is a critical event in neonatal life. We aimed to identify genes that are specifically expressed in the ductus arteriosus versus (the non-closing) aorta Gene expression profiling of laser-captured microdissected cells offers the opportunity to study gene e...

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 specif...

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 inves...
