| Abstract | During replication of the genetic material, cells often face hurdles that challenge DNA replication machinery, leading to replication stress. Multiple complex signalling pathways have evolved to counteract and overcome such challenges. However, DNA repair defects caused by inefficient functioning of the DNA damage response pathways (DDR) drive genomic instability, one of the hallmarks of cancer. Here, we review the known events in DNA replication that induce replication stress and the mechanisms deployed by DDR pathways to deal with and overcome replication stress. Since the defects in these molecular pathways are associated with tumour progression, we provide an update on the novel and promising druggable targets emerging from DDR pathways. Further, we discuss how viruses replicate their DNA by hijacking and exploiting the DDR pathways and the potential to target replication stress-associated molecules for the identification of new anticancer molecules. |
