Vitamin A and Retinoic Acid in Cognition and Cognitive Disease.
Annual review of nutrition, 2020The history of vitamin A goes back over one hundred years, but our realization of its importance for the brain and cognition is much more recent. The brain is more efficient than other target tissues at converting vitamin A to retinoic acid (RA), which ...

Retinoic acid and retinoic acid receptors in development
Molecular Neurobiology, 1995The vitamin A derivative retinoic acid (RA) and related compounds (retinoids) are utilized as signaling molecules in a diverse array of developmental and physiological regulatory processes, including many important in the developing and mature nervous system. Retinoids function by interaction with high affinity receptors of the nuclear receptor family,

Superoxidation of Retinoic Acid
Photochemistry and Photobiology, 2006Atmospheric pressure chemical ionization mass spectroscopy (APCI-MS) was used to examine the light-induced oxidation products of retinoic acid under conditions that favor and preclude its aggregation. We observed that in conditions that favor aggregation, i.e. in aqueous solutions, retinoic acid undergoes superoxidation to yield highly oxidized species.

Retinoic acid and retinoic acid receptors in craniofacial development
Seminars in Cell & Developmental Biology, 1997Interest in retinoids and craniofacial development originated independently from nutritional and teratological studies; however, the site of action of retinoids in normal development remains contentious. Recent transgenic strategies have shown that retinoic acid and nuclear retinoid receptors are required for the morphogenetic specification of cranial ...

Retinoic acid (RA) is now considered anormal metabolite of vitamin A. It has been established that RA maintains health and supports growth in animals but differs from other forms of vitamin A in that RA does not function in visual or reproductive processes.

Retinoic acid, an analogue of vitamin A, is known to be teratogenic in laboratory animals and has recently been implicated in a few clinical case reports. To study the human teratogenicity of this agent, we investigated 154 human pregnancies with fetal exposure to isotretinoin, a retinoid prescribed for severe recalcitrant cystic acne.

Retinoic acid is a metabolite of vitamin A that is necessary to maintain health in human and most of the other vertebrates. MicroRNAs (miR or miRNAs) are small, non-coding RNA particles that diminish mRNA translation of various genes and so can regulate critical cell processes including cell death, proliferation, development, etc.

Retinoic acid (RA), the active derivative of vitamin A, by acting through retinoid receptors, is involved in signal transduction pathways regulating embryonic development, tissue homeostasis, and cellular differentiation and proliferation. RA is important for the development of the heart.

Journal of the American Academy of Dermatology, 2001
The tissue distribution of retinoic acid (RA) throughout development is highly restricted, defined by the expression patterns of enzymes involved in RA synthesis and catabolism. Presented is a summary of recent research that examines the role of some of the enzymes involved in RA distribution, particularly those involved in RA catabolism (P450RAI ...

Retinoic acid and hindbrain patterning
Journal of Neurobiology, 2006AbstractRetinoid signaling plays an important role in the developmental patterning of the hindbrain. Studies of the teratogenic effects of retinoids showed early on that the hindbrain suffered patterning defects in cases of retinoid excess or deficiency.
