| 摘 要： | 多环芳烃(PAHs)化合物中的苯并a]芘和PAHs暴露检测标志物1-羟基芘与心脏功能障碍有关,但其生物学机制尚不清楚。为研究苯并a]芘和1-羟基芘对心脏的毒性作用,基于人胚胎干细胞分化心肌细胞(hESC-CM)研究了苯并a]芘和1-羟基芘对心肌细胞活性氧(ROS)生成、CYP基因表达和DNA损伤等的影响。结果表明,苯并a]芘和1-羟基芘对h ESC-CM活性无影响,但能显著增强细胞ROS水平,诱导DNA损伤。此外,苯并a]芘还能诱导细胞线粒体促凋亡基因的表达。研究表明,苯并a]芘和1-羟基芘能通过诱导氧化应激和DNA损伤事件导致h ESC-CM损伤,在一定程度上解释了多环芳烃暴露导致心脏疾病的分子机制。

| Abstract: | Benzoa]pyrene, as a carcinogenic polycyclic aromatic hydrocarbon (PAH) compound, has received great concern due to its high health risk. 1-hydroxypyrene, a metabolite of pyrene, is widely used as one biomarker for PAHs. Previous studies demonstrated that both benzoa]pyrene and 1-hydroxypyrene related with cardiac dysfunction, but the biological mechanisms have remained unclear. In the present study, toxic mechanisms of these two PAHs were evaluated using human embryonic stem cell derived cardiomyocytes (hESC-CM). The results showed that both benzoa]pyrene and 1-hydroxypyrene enhanced the intracellular level of ROS and induced DNA damage. Benzoa]pyrene also induced an expression of cell mitochondrial proapoptotic gene. Overall, the oxidative stress and DNA damage contributed to PAHs toxicity in cardiomyocytes and probably associated with heart diseases. |
