Abstract

The manganese-dependent superoxide dismutase (MnSOD) Ala16Val single nucleotide polymorphism (SNP) has shown to be associated to risk factors of vascular diseases. Brain-Derived Neurotrophic Factor (BDNF) plays an essential role in the plasticity and neuronal regeneration of the brain after vascular injuries. However, little is known about interaction between MnSOD Ala16Val SNP on stroke, a frequent neurologic disease that involves various interacting pathways, such as vascular dysfunctions, inflammation, and neurotrophic factors. In this sense, the objective of this study was to investigate the relationship between MnSOD Ala16Val SNP with BDNF levels on stroke and also its influence on nitrosative stress, inflammatory, apoptotic, and DNA damage parameters. For this, 88 subjects were investigated, 44 subjects poststroke and 44 healthy controls. Questionnaires were applied to clinical characteristics and after laboratorial exams were collected. We analyzed levels of oxidative/nitrosative stress, inflammatory, apoptotic, and DNA damage markers. We showed a higher proportion of VV genotype in poststroke as compared to healthy subjects. Nitrite/nitrate, Tumor Necrosis Factor-α, Caspase 3 (CASP 3) and 8 (CASP 8) activation, Acethylc...Continue Reading

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.
