Description | Retinol (Vitamin A) is a natural vitamin that is fat soluble. Retinol plays an important role in the metabolic functions of the retina, growth and differentiation of epithelial tissues, bone growth, reproduction and immune response. |
In vitro | 方法:人 SH-SY5Y 神经元细胞系用 Retinol (1-20 µM) 处理 24 h,使用 MTT assay 和 SRB assay 检测细胞活力。结果:7、10 和 20 µM 的 Retinol 能显著降低细胞活力。5 µM 以下的浓度不会影响 SH-SY5Y 细胞的 MTT 还原或 SRB 掺入,但在 7 µM 浓度下,这些参数会下降,表明与对照组相比,存活细胞的数量减少了。[1]方法:人肝癌细胞 HepG2 用 Retinol (1 µM) 处理 24 h,使用 Flow cytometry 检测 Retinol 分布。结果:用 1 µM Retinol 处理 1 天后,Retinol 阳性 HepG2 细胞在总细胞群中的百分比从 17.6% 增加到 69.8%。荧光分析显示 Retinol 位于 HepG2 细胞的细胞质中。[2] |
In vivo | 方法:为研究胎盘药代动力学和致畸性,将 Retinol (10-100 mg/kg) 灌胃给药给妊娠第 11 天的妊娠小鼠。结果:10 mg/kg Retinol 给药后,未观察到致畸作用。药代动力学研究显示,血浆、胚胎组织、胎盘、卵黄囊膜和胚胎外液中的 retinyl esters、retinol 和 all-trans-retinoic acid 适度增加。100 mg/kg Retinol 给药后,严重胎儿畸形的发生率很高。包括胚胎在内的所有区室中的 retinyl esters 和 retinol 显著增加,极性代谢产物 all-trans-retinoic acid 和 all-trans-4-oxoretinoic acid 大量产生。[3] |
