摘要

N6-methyladenosine (m6A) is the most common reversible mRNA modification, regulating fundamental cellular processes. It plays a vital role in aging and age-related diseases by influencing gene expression, RNA splicing, and stability. Growing evidence suggests that m6A modifications orchestrate key hallmarks of aging, including cellular senescence, stem cell exhaustion, and chronic inflammation factors that contribute to neurodegeneration, cardiovascular disease, and cancer. The intricate crosstalk between m6A and chromatin modifications is now recognized as a fundamental mechanism shaping age-associated epigenetic landscapes and influencing disease susceptibility. Core m6A regulators, such as METTL3, FTO, and ALKBH5, are implicated in age-related metabolic decline, neurodegeneration, and impaired tissue regeneration, making them promising therapeutic targets. Dysregulated m6A patterns are linked to aberrant RNA metabolism, protein aggregation, and synaptic dysfunction in Alzheimer’s and Parkinson’s diseases, while in cardiovascular and metabolic disorders, m6A modifications contribute to endothelial dysfunction, inflammation, and oxidative stress. Recent breakthroughs in computational modeling and RNA-editing technologies have revolutionized m6A research. High-precision deep-learning models (e.g., m6A-DCR) and CRISPR-based m6A editing tools provide powerful platforms to decode m6A’s role in aging and disease progression. These advances pave the way for novel therapeutic strategies, offering opportunities for early diagnostics, precision medicine, and personalized interventions. Despite these promising developments, challenges remain in translating m6A-targeted therapies into clinical applications. Future research must enhance treatment specificity, minimize off-target effects, and elucidate the broader implications of m6A in aging. Advancing our understanding of m6A’s functional landscape is essential for developing next-generation RNA-based therapeutics to combat aging and its associated diseases.
