(9Z)-β-Carotene or 9-cis-β-carotene is a 9-cis retinoic acid precursor in intestinal mucosal glands of humans. 9-cis retinoic acid is a ligand for nuclear receptor and retinoid X receptor (RXR). 9-cis-β-carotene participates in gene regulation. It is majorly present in liver. 9-cis-β-Carotene supplementation inhibits the progression of atherosclerosis. 9-cis-β-carotene may restore photoreceptors in retinitis pigmentosa (RP) and retinal dystrophies.

The aim of the present study was to determine to what extent 9-cis beta-carotene, one of the most abundant naturally-occurring cis-isomers of beta-carotene, can inhibit the growth of cervical dysplasia-derived cells in comparison with all-trans beta-carotene. We found that 9-cis
