| 1 | Novel epigenetic-based therapies useful in cardiovascular medicine显示文摘Epigenetic modifications include DNA methylation, his-tone modifications, and micro RNA. Gene alterations have been found to be associated with cardiovascular diseases, and epigenetic mechanisms are continuously being studied to find new useful strategies for the clinical management of afflicted patients. Numerous cardiovascular disorders are characterized by the abnormal methylation of Cp G islands and so specific drugs that could inhibit DNA methyltransferase directly or by reducing its gene expression(e.g., hydralazine and procainamide) are currently under investigation. The anti-proliferative and anti-inflammatory properties of histone deacetylase inhibitors and their cardio-protective effects have been confirmed in preclinical studies. Furthermore, the regulation of the expression of micro RNA targets through pharmacological tools is still under development. Indeed, large controlled trials are required to establish whether current possible candidate antisense micro RNAs could offer better therapeutic benefits in clinical practice. Here, we updated therapeutic properties, side effects, and feasibility of eme-rging epigenetic-based strategies in cardiovascular diseases by highlighting specific problematic issues that still affect the development of large scale novel therapeutic protocols. | Claudio Napoli Vincenzo Grimaldi Maria Rosaria De Pascale Linda Sommese Teresa Infante Andrea Soricelli | 2016 | World Journal of Cardiology2016，8，2： | 5 |
| 2 | 雌激素受体α基因甲基化与缺血性卒中的相关性研究显示文摘目的 DNA甲基化作为一种主要的表观遗传修饰模式,与许多疾病的发生及发展相关。而关于缺血性卒中病人基因甲基化方面的研究较少。本研究主要探讨人雌激素受体α(ER-α)基因启动子区甲基化状态与缺血性卒中的相关性。方法入选83例缺血性卒中患者和94例对照者,所有患者记录梗死灶大小,行NIHSS评分及Barthel指数评定。行颈动脉彩色超声及颅脑磁共振血管造影的患者,计算Crouse积分及斑块指数,评估颅内动脉硬化程度。所有研究对象均抽取清晨空腹静脉血,采用甲基化特异性聚合酶链反应(MSP)检测静脉血ER-α基因启动子区甲基化状态。结果缺血性卒中组ER-α基因启动子区甲基化检出率较对照组升高(42.2%比19.1%,P<0.05)。有52例患者行颈动脉彩色超声检查,完全甲基化组、部分甲基化组及非甲基化组间颈动脉内膜中膜厚度、Crouse积分及斑块指数存在差异(P<0.05)。有57例患者行颅脑磁共振血管造影检查,非动脉硬化组、动脉硬化组、动脉狭窄组及动脉闭塞组甲基化检出率有升高趋势(分别为40.9%、42.9%、52.4%、57.1%),但差异无统计学意义(P>0.05)。根据梗死灶大小分为小梗死组、中等梗死组和大梗死组,甲基化检出率依次增高(分别为32.8%、56.3%、77.8%),差异有统计学意义(P<0.05)。完全甲基化组、部分甲基化组及非甲基化组间NIHSS评分和Barthel指数存在差异(P<0.05)。结论缺血性卒中患者ER-α基因启动子区甲基化程度较对照组升高,其与颈动脉硬化程度、梗死灶大小、神经功能缺损严重程度等相关。 | 徐营营 周晓艳 谢兆宏 许顺良 于君 毕建忠 | 2015 | 中国动脉硬化杂志2015，23，10： | 3 |
