<blockquote>在一篇刊登在Nature Reviews Genetics期刊上的论文中,研究人员强调了在表观遗传学领域取得的成功以便预测肿瘤的行为和弱点。西班牙巴塞罗那市Bellvitge生物医学研究所癌症表观遗传学与生物学项目(Cancer Epigenetics and Biology Program at the Bellvitge Biomedical Research Institute)主任Manel Esteller教授领导的一个研究小组在这篇综述性论文中更新了在应用表观遗传学方面获得的最新研究发现。</blockquote>

科学家们越来越需要更好的生物标记物以便能够更早地检测人类疾病,特别是癌症。这些标记物能够改善对疾病的初级预防、诊断和预后。再者,根据病人的特征,人们也可能预测哪些人能够获得更加有效的治疗效果,即个体化治疗。<!--more-->
与传统方法相互补的基因检测被用来改善治疗不同疾病的方法,但是在过去十年,表观遗传学很少有助于解决这些临床表现。它是一种研究我们的遗传物质发生化学变化和调孔这些变化的蛋白的学科。最为著名的表观遗传标记是加入到DNA上的甲基基团。
在这篇论文中,研究人员注意道,在过去十年,基于两个基因MGMT和GSTP1甲基化的两项测试在预测脑瘤是否对药物替莫唑胺(temozolomide)敏感和区分前列腺癌是否良性生长中分别发挥着至关重要的作用。Esteller教授指出“最激动人心的是,他们当前正被鉴定为新的表观遗传标记来快速地预测肿瘤的表现和弱点。”

<br/><strong>DNA methylation profiling in the clinic: applications and challenges</strong><br/>
Holger Heyn & Manel Esteller
Knowledge of epigenetic alterations in disease is rapidly increasing owing to the development of genome-wide techniques for their identification. The ever-growing number of genes that show epigenetic alterations in disease emphasizes the crucial role of these epigenetic alterations — particularly DNA methylation — for future diagnosis, prognosis and prediction of response to therapies. This Review focuses on epigenetic profiling, which has started to be of clinical value in cancer and may in the future be extended to other diseases, such as neurological and autoimmune disorders.
