  • Research team discovers mechanism that restores cell function after genome damage

    A research team from Cologne has discovered that a change in the DNA structure – more precisely in the chromatin – plays a decisive role in the recovery phase after DNA damage. The key is a double occupation by two methyl groups on the DNA packaging protein histone H3 (H3K4me2). The discovery was ma more

  • Locating and severing lethal links

    Chemical lesions in the genetic material DNA can have catastrophic consequences for cells, and even for the organism concerned. This explains why the efficient identification and rapid repair of DNA damage is vital for survival. DNA-protein crosslinks (DPCs), which are formed when proteins are adven more

  • Bacteria leave signature in colon cancer cells

    Some bacterial pathogens cause damage in the genomes of their infected cells which could lead to the initiation of cancer. While it is difficult to link an infection with an onset of cancer that arises many years later in life, researchers have been looking for definitive proof that such links reall more
