角黄素

角黄素对MCF-7细胞中DNA分子有一定的损伤作用；番茄红素、玉米黄素和玉米黄素双棕榈酸酯对人乳腺癌细胞株MCF-7细胞中DNA分子均无损伤作用。

Canthaxanthin could also induce DNA damage of breast cancer cell line MCF-7 but lycopene , zeaxanthin and zeaxanthin dipalmitate could not .

结果：模型组细胞活力、SOD活性、细胞膜流动性均比不同角黄素组有显著降低（P＜0.01），而ROS含量、LPO含量均比不同角黄素组有显著升高（P＜0.01）。

Results : Compared with canthaxanthin groups , the activity of cells , SOD activity and membrane fluidity in the model group were significantly decreased ( P ﹤ 0.01 ) . However , the content of ROS and LPO were significantly increased ( P ﹤ 0.01 ) .

角黄素、玉米黄索和玉米黄素双棕榈酸酯对MDA-MB-435S细胞的凋亡发生无诱导作用；β-胡萝卜素、虾青素和番茄红素对MCF-7细胞的凋亡发生有诱导作用；

The apoptosis positive cells could be observed in the breast cancer cell lines MDA-MB-435s treated by B - carotene , astaxanthin and lycopene , but there were not apoptosis positive cells in the breast cancer cell lines MDA-MB-435s treated by canthaxanthin zeaxanthin and zeaxanthin dipalmitate ;
