Epigenetic alterations play a key role in the initiation and progression of cancer. Therefore, it is possible to use epigenetic marks as biomarkers for predictive and precision medicine in cancer. Precision medicine is poised to impact clinical practice, patients, and healthcare systems. The objective of this review is to provide an overview of the epigenetic testing landscape in cancer by examining commercially available epigenetic-based diagnostic tests for colon, breast, cervical, glioblastoma, lung cancers, and for cancers of unknown origin. We compile current commercial epigenetic tests based on epigenetic biomarkers (i.e., DNA methylation, miRNAs, and histones) that can actually be implemented into clinical practice.
表观遗传改变在癌症的发生和发展中起着关键作用。因此,有可能将表观遗传标记用作癌症预测和精准医学的生物标志物。精准医学有望对临床实践、患者和医疗保健系统产生影响。本综述的目的是通过研究用于结肠癌、乳腺癌、宫颈癌、胶质母细胞瘤、肺癌以及原发灶不明癌症的基于表观遗传的商用诊断测试,概述癌症表观遗传检测的现状。我们汇总了目前基于表观遗传生物标志物(即DNA甲基化、微小RNA和组蛋白)且可实际应用于临床实践的商用表观遗传测试。
