Abstract: BACKGROUND: Silent information regulator 1, as a deacetylase, can regulate the transcriptional activity of various proteins and many Alzheimer’s disease related pathological processes after activation, including regulating energy metabolism, oxidative stress, neuroinflammation, autophagy, and cell apoptosis. It is closely related to the occurrence, development, and prognosis of Alzheimer’s disease. In recent years, a large number of studies have found that the active ingredients and formulas of traditional Chinese medicine monomers can delay the development of Alzheimer's disease by activating the silent information regulator 1 signaling pathway, reducing cell apoptosis, protecting neurons, and inhibiting the formation of amyloid plaque.
OBJECTIVE: To explore the relationship between silent information regulator 1 and Alzheimer’s disease, as well as the action mechanism of traditional Chinese medicine in regulating the silent information regulator 1 signaling pathway for the treatment of Alzheimer’s disease.
METHODS: The CNKI, WanFang, VIP, SinoMed, and PubMed databases were searched using keywords: “Alzheimer's disease, dementia, SIRT1, inflammation, oxidative stress, inflammatory factors, signaling pathways, TCM monomers, compounds” in Chinese and English from January 2015 to March 2025 to search the articles addressing silent information regulator 1 and the regulatory mechanisms of traditional Chinese medicine. The literature that is not highly relevant to the study, repetitive, or outdated, were excluded. A total of 4 921 relevant articles were retrieved, and 154 articles were ultimately included for review.
RESULTS AND CONCLUSION: (1) Numerous experimental studies have confirmed that silent information regulator 1 plays an important role in Alzheimer's disease. (2) Traditional Chinese medicine can regulate the silent information regulator 1 signaling pathway through various means, such as sodium ferulate can improve the learning and memory abilities of Alzheimer's disease rats by enhancing the expression of silent information regulator 1 in the prefrontal cortex of Alzheimer's disease, thereby ameliorating neuronal damage caused by ischemia and hypoxia. Oyster peptides can enhance reactive oxygen species, reduce oxidative damage in hippocampal tissue, alleviate neuroinflammation, enhance synaptic function, reduce neuronal damage and death, exert neuroprotective effects, and improve cognitive dysfunction.

Key words: Alzheimer’s disease, silent information regulator 1, energy metabolism, oxidative stress, neurogenic inflammation, synaptic plasticity, traditional Chinese medicine, research progress
