Chinese population; CYP4F2 gene; Haplotype; Ischemic stroke; Single nucleotide polymorphism

The objective of this study was to explore the relationship between CYP4F2 gene polymorphism and ischemic stroke (IS) in the Han Chinese population. We performed a case-control study to genotype four single nucleotide polymorphisms (SNPs) (rs2108622, rs3093100, rs3093105, rs3093135) in the CYF4F2 gene. The genotype and haplotype distributions were compared between the ... more

eNOS; Essential hypertension; Han population; Haplotype; SNPs

Endothelial nitric oxide synthase (eNOS) plays an important role in maintaining blood pressure homeostasis and vascular integrity. Polymorphisms in the eNOS gene have been found to be associated with hypertension in different human populations, including Northern and Southern Chinese Han populations. To examine the relationship of three eNOS gene polymorphisms, T-786C ( ... more

Body weight; Cattle; Dapper1 gene; F-PCR-RFLP; Haplotype; SNPs

The Dapper1 protein plays important role in multiple developmental processes via negative modulation of the Wnt signaling pathway. We detected variations in Dapper1 in 1185 individuals from 5 Chinese cattle breeds and determined their effects on bovine body weight. Two silent mutations (g.8344C>T and g.8428C>T) in exon 6 along with two substitutions (g.10513A>G and g. ... more

Camellia sinensis; Expressed sequence tag; Haplotype; Nucleotide diversity; Single nucleotide polymorphisms

Tea is the second most popular non-alcoholic beverage in the world. In recent years, several molecular markers have been used in genetic studies of the tea plant. Yet, only a few single nucleotide polymorphisms (SNPs) have been reported. Here, we identified 818 putative SNPs from expressed sequence tag (EST) databases for the tea plant, which produced a frequency of 1 SNP/170 bp. A ... more

Chicken; FADS2; Fatty acid; Growth traits; Haplotype; Single nucleotide polymorphisms

Delta-6 fatty acid desaturases are rate-limiting desaturases involved in metabolic processes of fatty acids, and they are encoded by the FADS2 gene. In the current study, an F2 resource population of Gushi chickens crossed with Anak broilers was used to investigate the genetic effects of the chicken FADS2. Two adjacent single nucleotide polymorphisms (SNPs) ( ... more

Genetic polymorphism; Genotype; Haplotype; Killer cell immunoglobulin-like receptor (KIR); Polymerase chain reaction-sequence specific primers

The aim of this study was to explore the genetic polymorphism, genotype, and haplotype characteristics of the KIR locus in the Xinjiang Han population in order to establish a foundation for future analysis of the relationship between KIR genes and disease. KIR genes were detected by sequence-specific primer-polymerase chain reaction in 184 randomly selected, ... more

Cleaved amplified polymorphic sequence (CAPS); endo-PG gene; Haplotype; Insertion/deletions (indels); Single nucleotide polymorphism

Single nucleotide polymorphisms (SNPs) are the most abundant sequence variations found in plant genomes and are widely used as molecular genetic markers in genetic diversity studies and crossbreeding programs. In this study, we examined 113 DNA sequences of the endopolygalacturonase (endo-PG) gene from 67 peach accessions and found a total of 56 SNPs and 6 insertion/deletions ( ... more

5-HTR2A; Schizophrenia; Serotonin; Single-nucleotide polymorphism; TPH2

The serotoninergic system has been implicated in the etiology of schizophrenia and other behavioral disorders. Association studies have focused on the tryptophan hydroxylase 2 gene (TPH2) and the 5-hydroxytryptamine receptor 2A gene (5-HTR2A). We genotyped two single-nucleotide polymorphisms, A1438G of 5-HTR2A and intronic rs1386494 of TPH2 in the Malay ... more

Polymorphisms; Serotonin; Tobacco smoking

Previous studies have revealed a genetic component, including genetic polymorphisms in the serotonergic pathway, particularly in the serotonin receptor gene (5-HT2A). The aim of this study was to investigate associations of the T102C (rs6313) and A-1438G (rs6311) polymorphisms with tobacco use in a population from northeastern Brazil. We evaluated these polymorphisms in 135 ... more

5-hydroxytryptamine receptor 1A (5-HT1AR) is closely associated with cognitive functions. Selective serotonin reuptake inhibitors (SSRIs) can protect individuals from brain damage following ischemia/hypoxia. To investigate the function of SSRIs in vascular dementia (VD), we established a rat model of VD, and observed the effect of SSRIs on the expression of 5-HT1AR mRNA and neurotransmitters. ... more
