Cannabinoid receptor agonists diminish responses to painful stimuli. Extensive evidence implicates the CB(1) receptor in the production of antinociception. However, the capacity of CB(2) receptors, which are located outside the central nervous system (CNS), to produce antinociception is not known. Using AM1241, a CB(2) receptor-selective agonist, we(More)
Recently, the rs3129882 variant in intron 1 of HLA-DRA was found to be associated with late-onset sporadic Parkinson disease (PD) in Americans of European ancestry. To evaluate whether the same variant is related to PD in Chinese population, we investigated late-onset sporadic PD patients of Chinese Han ethanicity in Mainland China. We found significant(More)
The neurodegenerative diseases are a diverse group of disorders characterized by progressive loss of specific groups of neurons. These diseases affect different populations, and have a variable age of onset, clinical symptoms, and pathological findings. Variants in the FUS gene, which encodes an RNA-binding protein, have been identified as causative or risk(More)
Tourette syndrome is a complex neurological disorder that usually becomes evident between 4 and 18 years of age. The disorder is characterized by chronic motor and phonic tics, often with a variety of behavioural comorbidities; in particular, attention-deficit hyperactivity disorder, obsessive-compulsive disorder, and impulse control disorder. The cause of(More)
Growing evidences show that genetic abnormalities play an important role in the etiopathogenesis of Parkinson disease (PD). At least 18 genetic loci and 13 disease-related genes for parkinsonism have been identified. Recently, the p.Ala502Val and p.Arg1205His variants in the eukaryotic translation initiation factor 4-gamma 1 gene (EIF4G1) were found to be(More)
We have performed a case-control analysis of dopamine D2-like receptor (DRD2, DRD3 and DRD4) gene polymorphisms in 118 Han Chinese cases with bipolar affective disorder and 196 control subjects, and replication analysis in 157 English cases and 143 control subjects. We found association between a functional DRD2 promoter variant (P = 0.03 by allele) and the(More)
Although social and cultural influences are clearly important, family, twin and adoption studies indicate that genes contribute significantly to substance abuse. Substance abuse is associated with novelty seeking, a heritable human personality trait which may be influenced by alleles of the dopamine D4 (DRD4) gene exon III VNTR. Consequently Kotler et al(More)
Parkinson disease (PD; MIM 168600) is the second most common progressive neurodegenerative disorder characterized by a variety of motor and non-motor features. To date, at least 20 loci and 15 disease-causing genes for parkinsonism have been identified. Among them, the α-synuclein (SNCA) gene was associated with PARK1/PARK4. Point mutations, duplications(More)
BACKGROUND Mutations in the parkin gene (PRKN) cause autosomal recessive early-onset Parkinson disease (EOPD). OBJECTIVE To investigate the presence of mutations in the PRKN gene in a white family with EOPD and the genotype-phenotype correlations. DESIGN Twenty members belonging to 3 generations of the EOPD family with 4 affected subjects underwent(More)
