Abstract
Genomic DNA displays a non canonical structure prone to be damaged and modified by genotoxic stresses, which are induced either by the endogenous metabolism or attacks from environment or therapeutic pressure. Several molecular pathways allow cells to repair such DNA lesions. Additional mechanisms have been selected to bypass such damage at the price of mutations. The maintenance of the genome is thus mediated by the respect of a balance between accurate and inaccurate DNA transactions. This review deals with the tumor suppressor role of such equilibrium, as well as the impact of an unbalance on carcinogenesis.
