ABSTRACT
Ageing is an evolutionarily conserved and irreversible biological process in different species. Numerous studies have reported that taking medicine is an effective approach to slow ageing. Lemon extract (LE) is a natural extract of lemon fruit that contains a variety of bioactive phytochemicals. Various forms of LE have been shown to play a role in anti-ageing and improving ageing-related diseases. However, studies on the molecular mechanism of LE in Drosophila ageing have not been reported. In this study, we found that 0.05 g/L LE could significantly extend Drosophila lifespan and greatly improve antioxidative and anti-heat stress abilities. Furthermore, transcriptome and metabolome analyses of 10 d flies between the LE-fed and control groups suggested that the differentially expressed gene ppo1 (Prophenoloxidase 1) and metabolite L-DOPA (Levodopa) were co-enriched in the tyrosine metabolism pathway. Overall, our results indicate that affecting metabolism was the main reason for LE extending Drosophila lifespan.
