Objective: Activation of the constitutive nuclear and mitochondrial enzyme poly (ADP- ribose) polymerase (PARP) has been implicated in the pathogenesis of cell dysfunction, inflammation, and organ failure in various forms of critical illness. The objective of our study was to evaluate the efficacy and safety of the clinically approved PARP inhibitor olaparib in an experimental model of...

Effect of 3-mercaptopyruvate sulfurtransferase deficiency on the development of multiorgan failure, inflammation, and wound healing in mice subjected to burn injury

Ahmad, Akbar ; Druzhyna, Nadiya ; Szabo, Csaba

In: Journal of Burn Care & Research, 2019, vol. 40, no. 2, p. 148–156

The gaseous transmitter hydrogen sulfide (H2S) has been implicated in various forms of critical illness. Here, we have compared the outcome of scald burn injury in wild- type mice and in mice deficient in 3-mercaptopyruvate sulfurtransferase (3-MST), a mammalian H2S-generating enzyme. Outcome variables included indices of organ injury, clinical chemistry parameters, and plasma levels of...

Poly(ADP-ribose) polymerase (PARP) is involved in the pathogenesis of cell dysfunction, inflammation and organ failure during septic shock. The goal of the current study was to investigate the efficacy and safety of the clinically approved PARP inhibitor olaparib in experimental models of oxidative stress in vitro and in sepsis in vivo. In mice subjected to cecal ligation and puncture (CLP)...
