Inhibition of neuronal nitric oxide synthase-mediated activation of poly(ADP-ribose) polymerase in traumatic brain injury: neuroprotection by 3-aminobenzamide
Neuroscience
Neuroscience
Focal traumatic injury to the cerebral cortex is associated with early activation of the neuronal isoform of nitric oxide synthase (nNOS), where high concentrations of nitric oxide-derived free radicals elicit extensive DNA damage. Subsequent activation of the nuclear repair enzyme poly(ADP-ribose) polymerase (PARP) causes a severe energy deficit leading to the ultimate demise of affected neurons. Little is known about the temporal relationship of nNOS and PARP activation and the neuroprotective…
