Animal StudyHighlightedHydrogen-rich saline reduces cell death through inhibition of DNA oxidative stress and overactivation of poly (ADP-ribose) polymerase-1 in retinal ischemia-reperfusion injuryMHID-8429491PMID: 259549912015Molecular Medicine ReportsHONGWEI LIU, NING HUA, Keliang Xie, TINGTING ZHAO, Yonghao YuOveractivation of poly (ADP-ribose) polymerase 1 (PARP-1), as a result of sustained DNA oxidation in ischemia‑reperfusion injury, triggers programmed cell necrosis and apoptosis. The present study was conducted to demonstrate whether hydrogen‑rich saline (HRS) has a neuroprotective effect on retinal ischemia reperfusion (RIR) injury through inhibition of PARP‑1 activation. RIR was induced by trans
