A bacterial toxin that acts as a mediator rather than a killer

Traditionally, bacterial toxins have been seen as killers of target cells. But is there more than meets the eye? Umeå University Professor Teresa Frisan and her team have discovered that toxin-host interactions are more ...

Histone degradation after DNA damage enhances repair

DNA damage can occur anywhere in the genome, but most DNA is wrapped around nucleosomes making it inaccessible to the repair machinery. Researchers from the Gasser group now show that DNA damage induces histone depletion, ...

Researchers create bioluminescent tag to detect DNA break repair

A new bioluminescent reporter that tracks DNA double stranded break (DSB) repair in cells has been developed by researchers from Massachusetts General Hospital (MGH) and the Academia Sinica in Taiwan. The international team's ...
