9-cis Retinal is a naturally occurring retinoid, produced by the oxidation of 9-cis Retinol by cis-retinol dehydrogenase (cRDH), and can bind to retinol-binding protein (CRBP)[1, 2]. 9-cis Retinal can accelerate the differentiation and maturation of rod photoreceptor cells in retinal organoids[3].
In vitro, treatment of MCF7 human breast cancer cells transfected with cRDH cDNA (LRDHsn/MCF7) with 9-cis Retinal (1µM) for 1-7 days significantly inhibited cancer cell growth, with an inhibition rate of 75% after 24h[4].
In vivo, treatment of Irbp-/- mice with 9-cis Retinal (0.375mg) via intraperitoneal injection significantly restored cone photoreceptor function in the mice[5]. Treatment of retinitis pigmentosa model mice with 9-cis Retinal (2.5mg) once a week via gavage for 4 weeks significantly improved the visual function of both rod and cone photoreceptor cells in the mice[6].

| Cell experiment [1]: | |
Cell lines | LRDHSN/MCF7 cells |
Preparation Method | Cells were seeded into T25 tissue culture flasks at a density of 100,000 cells per square millimeter and cultured in complete tumor culture medium supplemented with either 1μM 9-cis Retinal or an equal volume of solvent (ethanol). The culture medium was changed every 48h. Cell counts were performed using a hemocytometer on days 1, 3, 5, and 7. |
Reaction Conditions | 1µM; 1, 3, 5, 7 days |
Applications | Within 24h of treatment, approximately 75% of the 9-cis Retinal was taken up and metabolized by LRDHSN/MCF7 cells. |
| Animal experiment [2]: | |
Animal models | Irbp-/- mice |
Preparation Method | Mice were anesthetized with xylazine (20mg/kg) and ketamine (80mg/kg), and pupils were dilated with phenylephrine hydrochloride (2.5%) and atropine sulfate (1%). Contact lens electrodes were placed on both eyes with a dropofmethylcellulose. Electroretinogram (ERGs) were recorded with the UTAS E-2000 system (LKC Technologies) using 10ms flashes of increasing light intensities under scotopic or photopic conditions. Cone recordings were made in the presence of a 30cd/m2 background light after 3min of light adaptation. Preparation and injection of 9-cis Retinal. 9-cis Retinal was prepared for injection under dim red light. The retinal was dissolved in ethanol (10% final injection volume) before adding the vehicle solution (10% BSA in 0.9% NaCl). After recording baseline ERGs, mice were rested 12h, administered 0.375mg of 9-cis Retinal intraperitoneally, and dark-adapted 12h before recordings were repeated. Photopic ERG responses of aging Irbp-/- mice were analyzed by one-way ANOVA. Kruskal-Wallis and Mann-Whitney U tests were used for cone density analysis. |
Dosage form | 0.375mg; i.p. |
Applications | Treatment with 9-cis Retinal produced a significant recovery of the cone response in Irbp-/- mice. |
