The study establishes a link between TDRD3 and an enzyme that unwinds DNA at regions of active gene expression, and provides evidence that this partnership can prevent DNA breakage and chromosomal translocations - two of the hallmarks of cancer.

The 1500 transcription factors (TFs) within the human genome perform a key role in determining the set of active genes within a specific cell, as well as the magnitude of activity.

He is interested in reactivating dormant genes or changing the regulation of active genes in embryos to bring back ancestral traits that have been lost in evolution.

«As a result of the previous study, we reported that SUMO is probably important for controlling expression of active genes because we found it on every gene we looked at, but only when they were turned on,» notes Rosonina.

The repertoire of active genes in their livers more closely resembled those of the northern Texas lizards, including genes involved in the functioning of the nervous and muscular systems.

These findings suggest that the acetylation reaction may not be the cause of active gene expression, or at least not sufficient to activate gene expression.

The study points to a future of active gene discovery for mental disorders» said Thomas Lehner, Ph.D., chief of the NIMH Genomics Research Branch, which funds the project.

Working copies of active genes — called messenger RNAs or mRNAs — are positioned strategically throughout living tissues, and their location often helps regulate how cells and tissues grow and develop.
