Summary
9-cis-Retinal is a natural retinoid. Dietary 9-cis-β-carotene generates 9-cis-retinoids via cleavage into 9-cis-retinal. 9-cis Retinal binds to cellular retinol-binding protein-I (CRBP-I) and CRBP-II with K d s of 8 nM and 5 nM, respectively. 9-cis-Retinal expedites differentiation and maturation of rod photoreceptors in retinal organoids [1] [2] [3] .
IC50 & Target
|
Human Endogenous Metabolite
|
In Vitro
The addition of 9-cis-Retinal, instead of the widely used all-trans retinoic acid, accelerates rod photoreceptor differentiation in organoid cultures, with higher rhodopsin expression and more mature mitochondrial morphology evident by day. 9-cis-Retinal can bind opsin to form functioning rhodopsin [3] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Treatment with 9-cis-retinal produced a significant recovery of the cone response in interphotoreceptor retinoid-binding protein (IRBP) -/- mice and shows that retinoid deficiency underlies cone dysfunction [4] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
