Interplay of transposable elements and ageing: epigenetic regulation and potential epitranscriptomic influence.

Transposable elements (TEs) are mobile elements, which have been crucial for mammalian genome evolution and function. Their activity, which influences genomic stability, gene expression and chromatin state, is tightly regulated by complex mechanisms. This review examines recent findings on TE regulation and the dynamics and connection during the ageing process. Here, we explore the interplay between chromatin state, DNA, RNA, and histone modifications in controlling TE activity, with a special emphasis in elucidating the emerging role of epitranscriptomic modifications in TE regulation. Additionally, we analyse the connection between TE activation and ageing, with the perspective for future research that could reveal novel targets for alleviating physiological and pathological ageing and age-related diseases.
