Oxaloacetate Neuroprotective Benefits

THE MECHANICS

rGOT works by converting excess glutamate into oxaloacetate, reducing excitotoxicity. Excessive glutamate during ischemia-reperfusion activates NMDA receptors, flooding neurons with calcium ions and causing cell death. rGOT also scavenges reactive oxygen species (ROS), mitigating oxidative stress and improving cerebral circulation. This dual mechanism of action makes rGOT a promising adjunct to rtPA therapy.

THE BIOLOGICAL LEVERAGE

In experimental models, rats treated with both rGOT and rtPA showed better neurological outcomes compared to those treated with rtPA alone. Histological analysis revealed a 30% reduction in infarct volume and less neuronal damage. Biochemically, glutamate levels were significantly reduced, SOD and GPX activities elevated, and MDA levels decreased—indicating a mitigation of oxidative stress.

THE TACTICAL IMPLEMENTATION

Administration of rGOT alongside rtPA enhances neuroprotection in ischemic stroke models. Experimental protocols involved intraperitoneal injection of rGOT at varying doses after MCAO induction. This approach could provide an effective strategy for improving therapeutic outcomes post-stroke, pending further clinical trials.
