DNA Damage and Checkpoint Pathways: Cell Skip to Main Content Advertisement Cell This
journal offers authors two options (open access or subscription) to publish research This …

The repair of DNA lesions that occur endogenously or in response to diverse genotoxic
stresses is indispensable for genome integrity. DNA lesions activate checkpoint pathways …

The DNA damage and replication checkpoints are signaling mechanisms that regulate and
coordinate cellular responses to genotoxic conditions. Unlike typical signal transduction …

In response to genomic insults cells trigger a signal transduction pathway, known as DNA
damage checkpoint, whose role is to help the cell to cope with the damage by coordinating …

Cell cycle checkpoint activation and DNA repair pathways govern genomic stability after
genotoxic stress. Genotoxic insult results in activation of an interwoven network of DNA …

In response to diverse genotoxic stresses, cells activate DNA damage checkpoint pathways
to protect genomic integrity and promote survival of the organism. Depending on DNA …

Cell cycle checkpoints activated by DNA double-strand breaks (DSBs) are essential for the
maintenance of the genomic integrity of proliferating cells. Following DNA damage, cells …

▪ Abstract DNA checkpoints play a significant role in cancer pathology, perhaps most notably
in maintaining genome stability. This review summarizes the genetic and molecular …

DNA damage checkpoint is one of the surveillance systems to maintain genomic integrity.
Checkpoint systems sense the DNA damage and execute cell cycle arrest through inhibiting …

DNA is prone to numerous forms of damage that can injure cells and impair fitness. Cells
have evolved an array of mechanisms to repair these injuries. Proliferating cells are …
