In mammals, the majority of DNA double-strand breaks are processed by the Non Homologous End-Joining pathway (NHEJ), composed of seven factors: Ku70, Ku80, DNA-PKcs, Artemis, Xrcc4 (X4), DNA Ligase IV (L4) and Cernunnos/XLF. Cernunnos is part of the ligation complex, constituted by X4 and L4. In order to improve our knowledge on the structure...

Hoyeraal-Hreidarsson syndrome (HHS) is a severe form of Dyskeratosis congenita characterized by developmental defects, bone marrow failure and im-munodeficiency and has been associated with telom-ere dysfunction. Recently, mutations in Regulator of Telomere ELongation helicase 1 (RTEL1), a helicase first identified in Mus musculus as being...

Non-alcoholic steatotic liver disease (NAFLD) is the most common cause of chronic liver disease worldwide. NAFLD has a major effect on the intrinsic proliferative properties of hepatocytes. Here, we investigated the mechanisms underlying the activation of DNA damage response during NAFLD. Proliferating mouse NAFLD hepatocytes harbor replication...
