Abstract: Objective:To observe the effect of carotenoids on the DNA damage of breast cancer cell of MDA-MB-435S.Methods:The breast cancer cells MDA-MB-435S were cultured with carotenoids in vitro.The DNA damage of breast cancercells was determined by the single cell gel electrophoresis assay.Results:β- carotene and astaxanthin could induce the DNAdamage of breast cancer cell-lines MDA-MB-435S and show dose-response and time-response relationship.Lycopene couldinduce the DNA damage of breast cancer cell-lines MDA-MB-435S,while canthaxanthin,zeaxanthin and zeaxanthin dipalmitatecould not induce the DNA damage of breast cancer cell-lines MDA-MB-435S.

Key words: carotenoids, breast cancer cells, DNA damage
