Results about: DNA damage


The recognition of many types of DNA lesions activates the cellular DNA damage response (DDR). The DDR orchestrates the appropriate cellular programs to maintain genome integrity after genotoxic stress.

Key role identified for enzymes in DNA replication and sensitivity to chemotherapeutic drugs

Published in Science Advances, the study shows that the TLK1 and TLK2 enzymes are critical for ensuring the copying of DNA.

Loss of TLK1 and TLK2 results in extensive DNA damage during DNA replication and in cancer cell death.

Depletion of TLK1/2 enhances the effectiveness of some chemotherapeutic agents currently being tested in clinical trials

Histone 1, the guardian of genome stability

Genomic instability is the main risk factor for tumour development in humans. Therefore understanding its origin and exploring therapeutic targets is paramount.

Histone 1 silences a region of the genome that causes irreparable DNA damage when translated and is lethal for the organism.
