Abstract
Objective: Epigenetics, including DNA methylation, histone modification, and posttranscriptional regulation of microRNAs, is the study of heritable changes in gene expression that do not include DNA-sequence alterations. Epigenetics has become a new strategy for basic and clinical research on acupuncture in the last decade. The aim of this research update was to summarize the epigenetic mechanisms of angiogenesis induced by acupuncture treatment in ischemic heart diseases. Materials and Methods: The current authors' group has been working to illustrate the mechanism of acupuncture from an epigenetics perspective, which has shed new lights on the mechanisms and applications of acupuncture in cardiovascular diseases. This article summarizes the group's new findings in animal models as well as in patients with chronic stable angina. Progress since 2011 in other teams' research in this field is also discussed in this article. Conclusions: Acupuncture could regulate histone modifications and could rescue patients who sustain ischemic injuries. This treatment could possibly work through promoting angiogenesis.
