Neuronal cells injured by ischemia and reperfusion to a certain extent are committed to death in necrotic or apoptotic form. Necrosis is induced by gross ATP depletion or 'energy crisis' of the cell, whereas apoptosis is induced by a mechanism still to be defined in detail. Here, we investigated this mechanism by focusing on a DNA damage-sensor,(More)
The association between (GT)n dinucleotide repeats in monoamine oxidase gene loci, monoamine oxidase A (MAOA) and B (MAOB), and Parkinson's disease (PD), Alzheimer's disease (AD), and Lewy body variant (LBV) of AD were determined. MAOA-GT polymorphisms were significantly associated with pure AD and LBV. MAOA-GT allele 113 was excessively represented in pure(More)
MOTIVATION Neurodegenerative disorders (NDDs) are progressive and fatal disorders, which are commonly characterized by the intracellular or extracellular presence of abnormal protein aggregates. The identification and verification of proteins interacting with causative gene products are effective ways to understand their physiological and pathological(More)
Carbon tetrachloride (CCl(4)) is routinely used as a model compound for eliciting centrilobular hepatotoxicity. It can be bioactivated to the trichloromethyl radical, which causes extensive lipid peroxidation and ultimately cell death by necrosis. Overactivation of poly(ADP-ribose) polymerase-1 (PARP-1) can rapidly reduce the levels of β-nicotinamide(More)
Non-amyloid beta (Abeta) component of Alzheimer's disease (AD) amyloid (NAC) coexists with Abeta protein in senile plaques. After exposure to NAC fibrils, cortical neurons of rat brain primary culture became apoptotic, while astrocytes were activated with extension of their processes. NAC fibrils decreased the activity of reducing(More)
Poly(ADP-ribose) polymerase-1 (PARP-1; EC 2.4.2.30), also termed as poly(ADP-ribose) synthetase, is a key enzyme in the recognition and repair of damaged DNA. Several conditions (e.g., ischemia-reperfusion or chemical-induced injury) have been shown to overactivate PARP-1, causing neurodegeneration and necrotic or apoptotic cell death from NAD+ and ATP(More)
We have developed a mouse monoclonal antibody 5C11 (IgG2a) against cell surface antigen of Ewing's sarcoma (ES). 5C11 specifically reacted with ESs but not with other small round cell tumours in childhood, i.e. neuroblastomas, primitive neuroectodermal tumours (PNETs), rhabdomyosarcomas and malignant lymphomas. 5C11 did not react with any other tumours in(More)
Selenocysteine lyase (SCL) catalyzes the decomposition of L-selenocysteine to yield L-alanine and selenium by acting exclusively on l-selenocysteine. The X-ray structural analysis of rat SCL has demonstrated how SCL discriminates L-selenocysteine from L-cysteine on the molecular basis. SCL has been proposed to function in the recycling of the micronutrient(More)
Polymorphism of CYP2D6 and its relationship with the development of Parkinson's disease (PD) has been controversial. The distribution of the B-mutation of CYP2D6, a mutation that results in the absence of a functional protein, differs by ethnicity and accounts for less than 1% of the 'poor metabolizer' phenotype in Asians. Thus, a meta-analysis was(More)
Septin 3 is a novel member of the septin subfamily of GTPase domain proteins. Human septin 3 was originally cloned during a screening of genes expressed in human teratocarcinoma cells induced to differentiate with retinoic acid. Alternative splicing of the septin 3 gene transcript produces two isoforms, A and B, in the human brain, though their regional(More)
