Transposable elements (TEs), once dismissed as "junk DNA," are now recognized as crucial regulatory elements. This review explores their significant role in sexual development, from germline activity to sex chromosome regulation.
Area of Science:
- Genomics
- Neuroscience
- Developmental Biology
Background:
- Transposable elements (TEs) constitute up to 50% of mammalian genomes.
- TEs are increasingly understood as adaptive regulatory elements, not just
- Their interaction with steroid receptors highlights a role in sexual development.
Purpose of the Study:
- To review the involvement of TEs in sexual development processes.
- To highlight sex differences in TE activity and gene regulation.
- To explore epigenetic mechanisms governing TEs in sexual development.
Main Methods:
- Literature review focusing on transposable elements and sexual development.
- Analysis of TE activity across germline and sex chromosomes.
- Examination of gene regulation by TEs in sexual development pathways.
Main Results:
- TEs are implicated in various aspects of sexual development, from germline to sex chromosomes.
- Sex-specific differences in TE activity and their regulatory roles are observed.
- TEs interact with steroid receptors, influencing sexual development.
Conclusions:
- Transposable elements play a vital, adaptive role in sexual development.
- Further research is needed to understand TEs' molecular networks and epigenetic regulation in sexual development across diverse organs and stages.
- Understanding TEs is crucial for a comprehensive view of sexual development.
