BACKGROUND Cigarette smoking has been associated with mood enhancing properties and modulating effects on serotonin activity. The loudness dependence (LD) of the auditory-evoked N1/P2-component has been related to serotonergic neurotransmission, i. e. the allelic variants in the promoter of the 5-hydroxytryptamine-transporter (5-HTT) gene (SCL6A4).(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)
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)
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)
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)
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)
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)
BACKGROUND Revealing the molecular changes in chronic ethanol-impaired neuronal differentiation may be of great importance for understanding ethanol-related pathology in embryonic development but also in the adult brain. In this study, both acute and long-term effects of ethanol on neuronal differentiation of human neuroblastoma cells were investigated. We(More)
The impact of the serotonin transporter (5-HTT) gene-linked polymorphic region (5-HTTLPR) on anxiety-related behavior and related cerebral activation has facilitated the understanding of neurobiological mechanisms of anxiety. However, the influence of the 5-HTTLPR genotype on hippocampal neuronal development and neurochemistry, which is relevant to anxiety(More)
For both juvenile astrocytomas and astrocytomas of adults, numerical and structural aberrations of chromosomes 1 and 7 have been described. To study the frequency of those aberrations in more detail and to exclude in vitro artifacts, we investigated directly prepared material from 18 juvenile and 26 astrocytomas of adults by fluorescence in situ(More)
