The integrity of human genomic DNA are constantly threatened by the action of endogenous and exogenous factors. It is estimated that more than 104 DNA lesions are occur in each mammalian cell each day. Depending on the intensity and type of the damage; cell cycle arrest, change in gene expression, stimulation of DNA repair, programmed cell death, cancer or cellular aging events may occur. To protect genomic integrity, cells have a complex network of DNA repair mechanisms. In this review, DNA repair mechanisms are discussed in general.
