摘要

Aging is a progressive and irreversible biological process that contributes to the pathogenesis of numerous age-related diseases. Elucidating the molecular mechanisms of aging is crucial for promoting healthy aging and extending healthspan. RNA-binding proteins (RBPs) are pivotal regulators of post-transcriptional gene expression and play essential roles in diverse biological processes. RBPs interact with both coding and non-coding RNAs to regulate RNA metabolism, stability, localization, and translation. Dysregulated RBP-RNA interactions have been closely associated with aging and age-related diseases. This review systematically summarizes the structural characteristics of RBPs and the evolution of methods used to study them. We focus on the molecular mechanisms of six key RBPs, namely HuR, AUF1, TTP, IGF2BP2, QKI, and LARP7, in the context of aging and age-related diseases. In addition, we discuss the regulatory functions of post-translational modifications of RBPs. Furthermore, we provide a multidimensional overview of RBP involvement in aging and age-related diseases through large language model (LLM)-based text-mining analysis. Our study provides a foundation for the comprehensive characterization of RBPs in aging and age-related diseases.
