INTRODUCTION A mutation at nucleotide position 3435 in exon 26 of the multidrug resistance 1 (MDR1) gene is the most frequently studied polymorphism in relation to multidrug resistance. However, there are conflicting data as to whether the CC or TT genotype of the 3435C>T polymorphism is associated with drug resistance. METHODS AND RESULTS We investigated(More)
Different biochemical pathways and cellular mechanisms play role in the pathogenesis of pulmonary hypertension (PH) in chronic obstructive pulmonary disease (COPD). Alveolar hypoxia is not the only determinant of vascular remodeling, genetic factors are thought to have additive effects. We aimed to investigate the effects of endothelial nitric oxide(More)
The authors performed linkage analysis in 39 families with autosomal recessive early-onset PD (AR-EOPD) negative for parkin and DJ-1 mutations. Eight families including three Japanese, two Taiwanese, one Turkish, one Israeli, and one Philippine showed evidence of linkage with PARK6 with multipoint log of the odds (lod) score of 9.88 at D1S2732. The results(More)
UNLABELLED DYT-1 dystonia is the most common primary dystonia seen in childhood. It is an autosomal dominantly inherited disorder caused by deletion of a GAG triplet in exon 5 of the DYT1 gene. It characteristically starts in a distal limb during late childhood, subsequently spreads to involve other body regions sparing oromandibular muscles. However,(More)
This study compared superoxide dismutase (SOD) and catalase (CAT) alleles in 97 consecutive children and adolescents with migraine to 96 healthy children and adolescents. Isolated genomic DNA was used as a template for SOD1 (35 A/C), SOD2 16 C/T, and CAT2 [(-262 C/T) and (-21 A/T)] allele genotyping. The SOD2 16 C/T genotype and C allele frequency differed(More)
There is no information about the role of transforming growth factor-beta 1 (TGF-β1) in the pathogenesis of pediatric migraine. This study included 100 consecutive children and adolescents in whom migraine was diagnosed and 88 healthy children and adolescents. The isolated genomic DNA was used as a template for TGFβ-1 (-800G/A, -509C/T, 869T/C [codon 10](More)
OBJECTIVE In this study, we aimed to investigate the association of W64R polymorphism of the β3-adrenergic receptor gene (β-3AR) with childhood obesity and related pathologies. METHODS β-3AR gene W64R genotyping was carried out in 251 children aged 6-18 years. Of these subjects, 130 were obese (62 boys) and 121 were normal-weight (53 boys). In the obese(More)
OBJECTIVE Exploring the (CAG)n expansion within IT 15 gene in Turkish Huntington's disease (HD) patients and its relation to downstream (CCG)n repeat polymorphism to elucidate population specific haplotypic heterogeneity. METHODS Twenty-seven patients with clinical diagnosis of HD from 19 families were sampled. The triplet repeats were evaluated by sizing(More)
