Outline
There are more than 60 million alcoholic liver disease (ALD) patients in China, which has become a public health problem that cannot be ignored. Moreover, the social problem of "alcohol culture" is still hardly to solve, so that safe and effective prevention and treatment for ALD are in urgent need clinically. Previous studies on ALD have focused on the direct damaging effects of alcohol and its toxic metabolites, while recent studies have shown that the pathogenesis of ALD also include alcohol metabolic reprogramming and endogenous metabolites disorder. Although the endogenous metabolites have no direct toxicity, its long-term effect should not be ignored. These endogenous metabolites could change epigenetic modifications, cause widespread and persistent abnormal gene expression and signal pathway activation abnormally to promote metabolic reprogramming and stamp it as "metabolic memory", which manifest pathological changes and promote ALD, especially liver fibrosis/cirrhosis and liver cancer. Based on this, the article reviews the important epigenetic modifications caused by related metabolites in ALD and their associated effects. The role of traditional Chinese medicine (TCM) and its active ingredients in regulating epigenetics was also analyzed. The results suggest that regulation of epigenetics and alteration of "metabolic memory" may be a novel mechanism of TCM in the prevention and treatment of ALD.
