OBJECTIVES The dopamine D2 receptor (DRD2) plays an important role in the reinforcing and motivating effects of ethanol. Several polymorphisms have been reported to affect receptor expression. The amount of DRD2, expressed in a given individual, is the result of the expression of both alleles, each representing a distinct haplotype. We examined the(More)
Interleukin 15 (IL-15) is a novel cytokine whose biological activities are similar to those of interleukin 2 (IL-2). The genomic sequence of human IL-15 has been isolated based on its sequence homology with a cDNA clone encoding human IL-15. The human sequence is 14968 bp in length and includes all six protein-coding exons and five introns. The location of(More)
BACKGROUND This study examined the hypothesis that allelic variants of the ionotropic glutamatergic N-methyl-D-aspartate receptor (NMDAR) are associated with vulnerability to alcoholism and some related traits. METHODS We investigated the silent G2108A and C2664T polymorphisms of the NMDAR1 and the NMDAR2B genes, respectively. The case control study(More)
The loudness dependence (LD) of the auditory-evoked N1/P2 component has been shown to be related to the central serotonergic neurotransmission. Allelic variants in the promoter region of the 5-hydroxytryptamine transporter (5-HTT) gene were shown to modulate serotonergic activity. It was hypothesized that the three genotypes (l/l, s/l, s/s) differ with(More)
Neuronal differentiation has evolved as an essential process even in the adult brain, once disturbed being associated with the pathogenesis of several psychiatric disorders. To study the effects of Raf kinase inhibitor protein (RKIP) on neuronal differentiation, we generated neuroblastoma cell lines overexpressing RKIP (RKIP(+)) and expressing RKIP-directed(More)
In a previous study, a primary culture of midbrain cells was exposed to 9-methyl-beta-carboline for 48 h, which caused an increase in the number of tyrosine hydroxylase-positive cells. Quantitative RT-PCR revealed increased transcription of genes participating in the maturation of dopaminergic neurons. These in vitro findings prompted us to investigate the(More)
We have karyotyped a total of twelve ependymomas using GTG-banding including seven for which preliminary results have already been published. One case showing hyperdiploid main line with two marker chromosomes was further analyzed by nonisotopic chromosome in situ suppression hybridization. It was shown that the marker chromosomes consisted of 1q, 14q and(More)
Serotonergic neurotransmission, which is involved in many psychiatric disorders, is mediated by the serotonin transporter protein. Gene coding for the serotonin transporter protein is designated SLC6A4, which has been differentially associated with anxiety-related behavioral traits and neuroticism in healthy subjects. To confirm the association between the(More)
Abnormalities in monoamine neurotransmission have been implicated in the pathogenesis of alcoholism, mood disorders and schizophrenia. Murine norepinephrine transporter gene (NET) has been mapped to a region on chromosome 8 where a quantitative trait locus for ethanol sensitivity. Therefore we tested whether norepinephrine transporter (NET) gene variants(More)
INTRODUCTION A different genetic background is postulated for alcoholics with early onset and with antisocial personality disorder (type 2 alcoholics) compared with those with late onset and without antisocial personality disorder (type 1 alcoholics). The dopamine transporter (DAT) and the serotonin transporter (SERT) are involved in endophenotypes that are(More)
