摘要
阿尔茨海默病(Alzheimer’s disease, AD)是老年人群中最常见的神经退行性疾病。它以细胞外β-淀粉样蛋白大量沉积和细胞内神经原纤维缠结形成为主要特征。癌症也是一种与年龄相关的疾病。流行病学研究表明，AD与癌症发病存在负相关性，即AD患者并发癌症的风险降低，反之亦然。表观遗传学机制在AD和癌症的发生、发展过程中都发挥着重要作用。本文将对AD和癌症发病的表观遗传学机制的最新进展进行综述，为用“整体观念”重新认识AD和癌症的相关性提供新的思路。

Abstract
Alzheimer’s disease (AD) is currently the most prevalent neurodegenerative disease in the aging population. It is characterized by massive deposition of extracellular β-amyloid peptide and formation of intracellular neurofibrillary tangles. Cancer is also an age-related disease. Some epidemiological studies have shown an inverse relationship between AD and the onset of various types of cancers, that is, the risk of cancer in patients with AD is reduced, and vice versa. Epigenetic mechanisms play important roles in the development of AD and cancer. In this article, we will review the recent research advances on the epigenetic mechanisms of AD and cancer onset, and provide new ideas for rethinking the relevance of AD and cancer with a “holistic concept”.
Key words: Alzheimer’s disease; cancer; epigenetic mechanism; inverse relationship
