BACKGROUND To investigate the relationship of five TP53 polymorphisms (p.P47S, p.R72P, PIN3 ins16bp, p.R213R and r.13494g>a) with the esophageal cancer (EC) risk in North Indians. MATERIALS AND METHODS Genotyping of p.P47S, p.R72P, PIN3 ins16bp, p.R213R and r.13494g>a polymorphisms of TP53 in 136 sporadic EC patients and 136 controls using polymerase chain reaction and PCR-RFLP. RESULTS The...
This paper describes a method for screening animal populations on an index of calculated probabilities of genotype status at an unknown single locus. Animals selected by such a method might then be candidates in test matings and genetic marker analyses for major gene detection. The method relies on phenotypic measures for a continuous trait plus identification of sire and dam. Some missing phen...
Meiotic recombination is a genetic process that is critical for proper chromosome segregation in many organisms. Despite being fundamental for organismal fitness, rates of crossing over vary greatly between taxa. Both genetic and environmental factors contribute to phenotypic variation in crossover frequency, as do genotype-environment interactions. Here, we test the hypothesis that maternal ag...
UNLABELLED Objective(s) : Apolipoprotein E genotype (APOE) polymorphism affects lipid levels and coronary artery disease (CAD) risk. The aim of this study was to study the association of the Apolipoprotein E genotypes with coronary artery disease in the Iranian population. MATERIALS AND METHODS The Apolipoprotein E genotype in DNA samples extracted from 66 CAD+ patients and 61 control subject...
background: the t allele of the hepatic lipase (hl) c-514t polymorphism was previously found to be associated with lower plasma hl activity. here, we examined the association between this polymorphism and plasma hdl-cholesterol concentrations in patients with coronary arteries stenosis. methods: we studied 342 subjects undergoing coronary angiography in two groups of non cad (n=146) and cad (n=...
conclusions there were significant linkages between hcv genotypes and il28b genotypes/alleles. patients with a favorable il28b and genotypes 1 and 4 hcv infection stand a better chance to clear hcv in the acute phase. objectives this meta-analysis was designed to determine the world-wide distribution patterns of il28b genotypes and alleles, and to find possible linkages between il28b and hcv ge...
OBJECTIVE Resistin is an adipocyte-secreted cytokine associated with insulin resistance in mice. We previously reported that the G/G genotype of a resistin single nucleotide polymorphism (SNP) at -420 increases type 2 diabetes susceptibility by enhancing its promoter activity. The aim of the present study was to determine the relevance of SNP -120 in a large number of subjects. RESEARCH DESIG...
The study was carried out in Sahiwal, Holstein Friesian, Jersey and crossbred cattle and Murrah, Bhadwari, Jaffarabadi, Nagpuri and Surti buffaloes maintained at different organized herds to work out the polymorphism at growth hormone locus and study its effect on birth weight. A 223 bp fragment of the gene was amplified and digested with Alu I restriction enzyme. Two alleles, L and V with thre...
Objective The spectrum of molecular defects in Chinese patients with 21-hydroxylase deficiency (21-OHD), and genotype-phenotype relationships are unknown. Methods We screened eight patients with non-classical (NC) 21-OHD and 35 with classical 21-OHD, and detected nine known mutations. Results The most frequent mutation among the 43 21-OHD cases was p.Ile172Asn (allele frequency, 36.0%), followe...
this study involves in vitro androgenesis of zea maysl. via anther culture. combination of two embryoinduction media (imss & ypm) in presence of different colchicine concentrations (0, 100, 200, 250, 300and 400 mg/l ) in the pretreatment medium (iml) andpretreatment duration (0, 3, 6 and 9 days) in twogenotypes (dh5×dh7 and eth-m82) were tested.after colchicine pretreatment, anthers were tr...
