2-arachidonoylglycerol (2-AG) is an endogenous cannabinoid receptor ligand. To date, two types of cannabinoid receptors have been identified: the CB1 receptor, abundantly expressed in the brain, and the CB2 receptor, expressed in various lymphoid tissues such as the spleen. The CB1 receptor has been assumed to play an important role in the regulation of(More)
BACKGROUND The SERPINA1, SERPINA3, and SERPINE2 genes, which encode antiproteases, have been proposed to be susceptible genes for of chronic obstructive pulmonary disease (COPD) and related phenotypes. Whether they are associated with emphysema is not known. METHODS Twelve previously reported single nucleotide polymorphisms (SNPs) in SERPINA1 (rs8004738,(More)
BACKGROUND Lymphotoxin-alpha (LTA) is a pro-inflammatory cytokine with anti-tumor activity. The objective of this study was to determine whether LTA polymorphisms influence the presence of cancer. METHODS LTA polymorphisms C804A (rs1041981, T60N) and T495C (rs2229094, C13R) were determined in 1,536 consecutive autopsy cases and were registered in the(More)
BACKGROUND Previous studies of a functional variant of the catechol-O-methyl transferase (COMT) gene, Val158Met, have provided inconsistent results with regard to blood pressure or hypertension. We examined the effect of this variant, the considering environmental factors of daily salt and energy intakes. METHODS A total of 735 Japanese men (mean age, 47(More)
OBJECTIVE This study ascertained the association between attention deficit/hyperactivity disorder (ADHD) in Japanese children and a polymorphism of catechol-O-methyltransferase (COMT), a dopamine-control gene. The secondary aim of the study was the evaluation of a putative association between methylphenidate (MPH) effect/adverse effects and the COMT(More)
BACKGROUND The Ryanodine receptor 3 gene (RYR3) encodes an intracellular calcium channel that mediates the efflux of Ca2+ from intracellular stores. Two single-nucleotide polymorphisms (SNPs) in the RYR3 gene have been shown to associate with stroke (rs877087) and carotid intima-media thickness (rs2229116) in two independent genome-wide association studies(More)
Collagen components in neurofibroma tissue from patients with von Recklinghausen disease were investigated, in comparison with those in normal skin and peripheral nerve tissue. Biochemical analysis of collagen isolated from the tissues by limited pepsin digestion indicated that the neurofibroma tissue contained type I collagen as the major constituent and(More)
