[Advances in epigenetics in ischemic stroke]

Ischemic stroke is one of the main causes of death and long-term disability worldwide, which seriously affects the quality of life of patients and brings a heavy economic burden to families and society. Epidemiological studies have shown that stroke has become the second leading cause of death and major disabling disease in the world, with the characteristics of high morbidity, high recurrence, and high mortality. Epigenetic mechanism is the molecular process where gene expression and function in each cell are dynamically regulated and interconnected and a biological mechanism that changes genetic performance without changing the DNA sequence, including DNA methylation, histone modifications, and non-coding RNA. However, the research on epigenetics is currently focused on other diseases such as tumors. Recent studies have found that epigenetics has received extensive attention in the past few decades as a key factor involved in the pathophysiological process of ischemic stroke. The present study introduced the mediation of epigenetics in the induction of stroke, summarized the potential drug targets for these mechanisms in the treatment of stroke, and further explored the significance of traditional Chinese medicine(TCM) against cerebral ischemia injury based on TCM classification of stroke.
