Abstract
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.
期刊介绍：
Current Opinion in Genetics and Development aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed.
In Current Opinion in Genetics and Development we help the reader by providing in a systematic manner:
1. The views of experts on current advances in their field in a clear and readable form.
2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.[...]
The subject of Genetics and Development is divided into six themed sections, each of which is reviewed once a year:
• Cancer Genomics
• Genome Architecture and Expression
• Molecular and genetic basis of disease
• Developmental mechanisms, patterning and evolution
• Cell reprogramming, regeneration and repair
• Genetics of Human Origin / Evolutionary genetics (alternate years)
