咖啡因和阿司匹林被认为与精神分裂症等神经系统疾病有关,并且先前的数据显示HERV-W元件的异常表达可能是这些疾病的发病机制中的重要因素。在本文中,我们报道了咖啡因和阿司匹林有助于HERV-Winvandgagin在人神经母细胞瘤细胞SH-SY 5 Y中的表达。采用半定量RT-PCR和实时荧光定量PCR检测咖啡因和阿司匹林对HERV-Wevandgagin细胞mRNA表达的影响。Western blotting检测HERV-Wenv蛋白表达,荧光素酶活性检测HERV-Wenv启动子活性。结果发现,咖啡因和阿司匹林均能增加SH-SY 5 Y神经母细胞瘤细胞中HERV-Winvandgagin的表达。咖啡因可以激活HERV-Wev启动子,而阿司匹林不能。根据以往的研究,我们可以推测HERV可能在环境因素(如药物和神经系统疾病)之间发挥桥梁作用。
Caffeine and aspirin have been suggested to be involved in neurologic diseases, such as schizophrenia, and previous data have revealed that abnormal expression of HERV-W elements may be an important factor in the etiopathogenesis of those diseases. In this article, we reported that caffeine and aspirin contributed to the expression of HERV-Wenvandgagin Human SH-SY5Y neuroblastoma cells. Semi-quantitative RT-PCR and quantitative Real-time PCR were used to detect the mRNA of HERV-Wenvandgagin cells exposed to caffeine or aspirin. Western blotting was used to detect the protein of HERV-Wenv.Luciferase activity assay was employed to detect the activity of HERV-Wenvpromoter. It was found that both caffeine and aspirin could increase the expression of HERV-Wenvandgagin human SH-SY5Y neuroblastoma cells. Caffeine could activate the HERV-Wenvpromoter, while aspirin could not. With previous studies we can conjecture that HERVs might play a bridging role between environmental factors, such as drugs and neurologic diseases.
