Cell death is commonly associated with the enzymatic fragmentation of DNA. Cells have excessive DNA-degrading power provided by the group of DNases/endonucleases which includes: DNase I, DNase II, caspase-activated DNase, endonuclease G, DNase gamma and several other enzymes. Sometimes these enzymes are called “apoptotic endonucleases,” however they participate in necrosis, mitotic catastrophe, autophagy and other modes of cell death. Other roles of the DNases include clean-up after cell death, removal of foreign DNA inside the cell, and cleavage of DNA circulating in blood. Normally, host cell DNA is protected against the DNases. However, during toxic cell injury or disease, genomic DNA becomes accessible to DNases due to the change of cellular homeostasis and increased permeability of membranes. We try to identify endonucleases, which participate in premortem DNA fragmentation in renal tubular epithelium during ischemic or toxic acute renal failure, in heart and brain during ischemia, and in cancer cells during chemotherapy. Our studies show that an inhibition or inactivation of DNases is protective against cell death in different models. Therefore, DNases can be used as tools or targets to either decrease tissue injury in various diseases, or selectively increase injury of cancer tissues. DNase inhibition can be achieved by specific chemical inhibitors, which were recently identified by our team.
