MicroRNA serves as critical factors in diverse biological events. However, it remains poorly understood how microRNAs contribute to the regulation of lifespan and age-associated changes, such as alterations in metabolic activity and an increased incidence of disorders. We aim to understand how microRNAs regulate stress response pathways and caloric restriction-mediated lifespan extension using the nematode Caenorhabditis elegans, an excellent model organism for ageing biology.
