AbstractSystemic treatment of mice with the herbicide paraquat causes the
selective loss of nigrostriatal dopaminergic neurons, reproducing the primary
neurodegenerative feature of Parkinson's disease. To elucidate the role of
oxidative damage in paraquat neurotoxicity, the time‐course of neurodegeneration
was correlated to changes in 4‐hydroxy‐2‐nonenal (4‐HNE), a lipid peroxidation
marker. When ... hiện toàn bộ
Molecular Cloning and Regional Distribution of a Human Proton Receptor Subunit with Biphasic Functional PropertiesJournal of Neurochemistry - Tập 72 Số 1 - Trang 51-57 - 1999
K. Babinski, Khanh-Tuoc Lê, Philippe Séguéla
Abstract : Small changes of extracellular pH activate depolarizing inward
currents in most nociceptive neurons. It has been recently proposed that acid
sensitivity of sensory as well as central neurons is mediated by a family of
proton‐gated cation channels structurally related to Caenorhabditis elegans
degenerins and mammalian epithelial sodium channels. We describe here the
molecular cloning of ... hiện toàn bộ
Presynaptic Adenosine A2 and N‐Methyl‐D‐Aspartate Receptors Regulate Dopamine Synthesis in Rat Striatal SynaptosomesJournal of Neurochemistry - Tập 56 Số 5 - Trang 1783-1788 - 1991
Muhammad Abdul Baker Chowdhury, Marianne Fillenz
Abstract: Dopamine synthesis rate and cyclic AMP concentration were measured in
synaptosomes prepared from rat striatum. Dopamine synthesis rate was decreased
by the addition of either adenosine deaminase or 8‐phenyltheophylline, an
adenosine receptor blocker, and was increased by the addition of
2‐chloroadenosine. The addition of L‐glutamate in the absence of adenosine
deaminase decreased both do... hiện toàn bộ
Tissue Distribution of Human Monoamine Oxidase A and B mRNAJournal of Neurochemistry - Tập 55 Số 4 - Trang 1166-1169 - 1990

Abstract: Monoamine oxidase (MAO) A and B play important roles in the metabolism
of biogenic amines. Northern analysis using 32P‐labeled subfragments of human
liver MAO A and B cDNA clones detected a 5‐ and a 3‐kb transcript, respectively,
in most human tissues examined. However, fetal heart and thymus express minute
amounts of MAO A transcript, whereas fetal brain, muscle, thymus, spleen,
meninge... hiện toàn bộ
