Description
  • Multifunční mitochondriální enzym 17beta-hydroxysteroidová dehydrogenáza typu 10 by mohl hrát roli ve vývoji Alzheimerovy nemoci svou vysokoafinitní vazbou k peptidům amyloidu beta a zvýšenou expresí. Testovali jsme specificitu změn v mRNA/enzymové expresi v pravém a levém hipokampu lidí. U nedementních nepsychotických kontrol jsme nalezli trend k pravo/levé lateralitě, stupeň asymetrie byl však vyšší u mRNA než u exprese enzymu. U Alzheimerovy nemoci a u schizofrenie jsme pozorovali naopak levo/pravou asymetrii, která byla způsobena výraznějším nárůstem v levé hemisféře. Naše výsledky potvrzují vyšší zranitelnost dominantní hemisféry k patologickým procesům. Zvýšená exprese enzymu by mohla být využita k rozlišení Alzheimerovy nemoci od multi-infarktové demence. (cs)
  • Objective: The multifunctional mitochondrial enzyme 17 beta -hydroxysteroid dehydrogenase type 10 could play a role in the development of Alzheimer disease via its high-affinity binding to amyloid- peptides and its overexpression. Methods: We evaluated the specificity of alterations in mRNA/enzyme expression levels in human right and left hippocampi. Results: We observed a trend towards right/left laterality in nondemented nonpsychotic controls; however, the degree of asymmetry was higher for mRNA when compared to enzyme expression levels. In Alzheimer disease and schizophrenia, significant shifts to left/right asymmetry were found and the changes were associated with more marked increases in mRNA/enzyme expression in the left hemisphere. On the other hand, no alterations were observed in people with multi-infarct dementia. Conclusion: Our results support studies reporting an impairment of mitochondria in Alzheimer disease or schizophrenia and a higher vulnerability of the dominant hemisphere to path
