In summary, our study underscores the richness of information on the transcriptional regulation of repetitive elements, and transposable elements in particular, contained in publically available, high throughput sequencing datasets.
Results and literature evidences lead to a stage-equilibrium hypothesis: multi-element system can maintain and stabilize its function and systematic level under environmental stress through the self-regulation of element proportions.
The positive feedback could be realized by for instance the mutual activation/positive regulation of two elements, or alternatively through the mutual inhibition of two elements.
Viral miRNAs can regulate both cellular and viral gene expressions through the regulation of cellular elements involved antiviral responses, simulating cellular miRNAs, or targeting their own viral messenger RNAs to modulate the viral replication cycle.
To investigate the effect on the regulation of repeat elements caused by DNA methylation in the chicken, we first confirmed the methylation level of repeat elements and its flanking regions.

Furthermore, a role for small RNAs in the regulation of transposable elements during gametogenesis is emerging.
Formation of solid CaPO4 in primitive organisms is believed to enable the storage and regulation of essential elements such as calcium, phosphorus and, possibly, magnesium.
Since McClintock's time, we have learned that a great deal of cell sensing involves the epigenetic regulation of mobile elements and other aspects of genome function.
