(Submitter supplied) Retinoic acid (RA) is an important developmental signaling molecule responsible for the patterning of multiple vertebrate tissues. RA is also a potent teratogen, causing multi-organ birth defects in humans. Endogenous RA levels must therefore be tightly controlled in the developing embryo. In order to understand the RA function and regulation at the genomic level, we used a microarray approach to identify genes that function as negative feedback regulators of retinoic acid signaling. more...

(Submitter supplied) We are presenting the application of toxicogenomics in the evaluation of the toxic effects of retinoic acid and one of its isoforms the 9-cis retinoic acid. The main goal is to distinguish the pattern of action of the both chemical compounds and their action in an extended exposure. The results suggest a different pattern within the days and the chemicals. Representatives of each GO functional groups were selected and quantified by real-time PCR to validate the microarray data and to differentiate the action of retinoic acid compounds studied.

(Submitter supplied) Retinoic acid (RA), an active derivative of the liposoluble vitamin A (retinol), acts as an important signaling molecule during embryonic development, regulating phenomenons as diverse as anterior-posterior axial patterning, forebrain and optic vesicle development, specification of hindbrain rhombomeres, pharyngeal arches and second heart field, somitogenesis, and differentiation of spinal cord neurons. more...

Analysis of anterior and posterior brain regions from Retinaldehyde Dehydrogenase 2 null-mutant (Raldh2-/-) embryos, which are unable to synthesize retinoic acid (RA) from maternally-derived retinol. Results provide insight into the repertoire of RA-regulated genes in the developing embryo.

(Submitter supplied) The patterning of the facial midline involves early specification of neural crest cells to form skeletal tissues that support the upper jaw . In order to understand the molecular mechanisms involved we have taken advantage of a beak duplication model developed in the chicken embryo. Here we can induce the transformation of the side of the beak into a second midline that is easily identifiable by the formation of a supernumerary egg tooth. more...

(Submitter supplied) In our search for biomarkers of maldevelopment, we focused on chemically-induced perturbation of the retinoic acid signaling pathway (RA-SP), a major pathway implicated in a plethora of developmental processes. A genome-wide expression screening was was performed on zebrafish embryos treated with two teratogens, all-trans retinoic acid (ATRA) and valproic acid (VPA), and a negative control, folic acid (FA).

(Submitter supplied) Retinoic acid (RA) is a central developmental signal whose perturbation results in teratogenic outcomes. RA is tightly regulated during early embryonic development to achieve fine-tuning of the instructive and permissive signals regulating multiple developmental processes including head formation. We aim to identify the key mechanisms underlying the homeostatic regulation and tuning of the retinoic acid signaling levels, the disruption of which in the head lead to wide ranging developmental malformations including microcephaly and other craniofacial defects. more...
