Researchers discover a way to Fight the Aging Process and Cancer Development

The DREAM protein complex prevents the repair of genome damage in human cells, in mice and in the nematode Caenorhabditis elegans, a team of researchers at the University of Cologne has discovered. They also successfully inhibited this complex for the first time using a pharmaceutical agent.

“When we suppress the so-called DREAM complex in body cells, various repair mechanisms kick in, making these cells extremely resilient towards all kinds of DNA damage,” said Professor Dr Björn Schumacher, Director of the Institute for Genome Stability in Aging and Disease at the University of Cologne...
