physiological function | generation of A549 lung adenocarcinoma cell lines with stably suppressed PARG and poly(ADP-ribose) polymerase PARP-1 expression, i.e. shPARG and shPARP1 cell lines, respectively. shPARG cells accumulate large amounts of poly-(ADP-ribosyl)ated proteins and exhibit reduced PARP activation. Hydrogen peroxide-induced cell death is regulated by PARG in a dual fashion. Whereas the shPARG cell line is resistant to the necrotic effect of high concentrations of hydrogen peroxide, these cells exhibit stronger apoptotic response. Both shPARP1 and especially shPARG cells display a delayed repair of DNA breaks and exhibit reduced clonogenic survival following hydrogen peroxide treatment. Translocation of apoptosis-inducing factor cannot be observed, but cells can be saved by methyl pyruvate and alpha-ketoglutarate | Homo sapiens |
