Phytoestrogen α-Zearalanol Attenuates Homocysteine-Induced Apoptosis in Human Umbilical Vein Endothelial Cells

Figure 9

Pretreatment with α-ZAL reduced the expression of 3-nitrotyrosine in homocysteine-challenged HUVECs (Western blot). The expression of 3-nitrotyrosine was significantly increased after treatment with 500 μmol/L homocysteine for 24 h. Pretreatment with α-ZAL could attenuate this effect. Data were presented as mean ± SD. versus Vehicle, versus Hcy alone. α-ZAL: α-zearalanol; 17β-E2: 17β-estradiol; Hcy: homocysteine; 3-NT: 3-nitrotyrosine.
