New findings shed light on the repair of UV-induced DNA damage

An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system in recognizing and repairing DNA that has been damaged by ultraviolet (UV) light. The investigators at Kobe University ...

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, ...

RNA information transfer could be used in repairing DNA

Genomes are routinely subjected to DNA damage. But most cells have DNA repair systems that enforce genome stability and, ideally, prevent diseases like cancer. The trouble gets serious when these systems break down. When ...

DNA damage caused by migrating light energy

Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers at Karlsruhe Institute of Technology (KIT) have demonstrated that DNA damage may also occur ...

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 ...

New method reveals where DNA is at risk in the cell

Researchers at Karolinska Institutet have developed a new sequencing method that makes it possible to map how DNA is spatially organized in the cell nucleus—revealing which genomic regions are at higher risk of mutation ...

Real-time observation of enzymatic processes on DNA

DNA damage in general and DNA strand breaks in particular occur every day in all cells of the human body. This is due to internal influences such as free radicals, which are produced during inflammatory processes and cellular ...
