Understanding the phenomena underlying non-selective susceptibility to ischemia of py-ramidal neurons in CA3 area hippocampus is important from point view elu-cidating mechanisms memory loss and development post-ischemic dementia. We used an ischemic model Alzheimer's disease study changes amyloid protein precursor gene expression, its cleavage enzymes tau af-ter a 10-minute brain with 12, 18, 24-month survival. Quantitative reverse tran-scriptase PCR assay showed that expression all genes contribute pro-duction was dysregulated within 2 years after ischemia. The above control values at times study. α-secretase also exceeded throughout In contrast, β-secretase reaching maximum increase 12 months ischemia, below 18 again 24 Presenilin 1 significantly elevated follow-up period, peak both occurring This suggests studied are involved non-amyloidogenic processing precursor. Also, observation present is-chemia. Data indicate episode long-term survival causes damage death pyramidal manner dependent on modified protein. Thus defining new mechanism neuronal addition modification is-chemia useful identifying disease.
