Viral and Cellular Genomes Activate Distinct DNA Damage Responses
In response to cellular genome breaks, MRE11/RAD50/NBS1 (MRN) activates a global ATM DNA damage response (DDR) that prevents cellular replication. Here, we show that MRN-ATM also has critical functions in defending the cell against DNA viruses. We reveal temporally distinct responses to adenovirus genomes: a critical MRN-ATM DDR that must be inactivated by E1B-55K/E4-ORF3 viral oncoproteins and...
متن کاملCellular responses to DNA damage.
For many years, the study of the regulation of the SOS network was complicated by both the complexities of the responses and the interrelationships of the key regulatory elements. However, recently the application of powerful genetic and molecular biological techniques has allowed us to gain a detailed picture of the regulation of this complex network. The network is now known to consist of mor...
متن کاملCellular responses to DNA damage.
Cells are constantly under threat from the cytotoxic and mutagenic effects of DNA damaging agents. These agents can either be exogenous or formed within cells. Environmental DNA-damaging agents include UV light and ionizing radiation, as well as a variety of chemicals encountered in foodstuffs, or as air- and water-borne agents. Endogenous damaging agents include methylating species and the rea...
متن کاملCellular Responses to Cisplatin-Induced DNA Damage
Cisplatin is one of the most effective anticancer agents widely used in the treatment of solid tumors. It is generally considered as a cytotoxic drug which kills cancer cells by damaging DNA and inhibiting DNA synthesis. How cells respond to cisplatin-induced DNA damage plays a critical role in deciding cisplatin sensitivity. Cisplatin-induced DNA damage activates various signaling pathways to ...
متن کاملInduction of Nucleic Acid Damage in Viral Genomes Using Riboflavin in Combination with UV Light
Background and Aims: Despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. Blood-borne pathogen transmission has been a concern since the earliest days of transfusion. The blood product of platelet (PLT) concentrates is still faced with the risk of bacterial and viral contaminations. Pathogen inactivation technologies offer a proac...
