Celiac disease is a chronic autoimmune condition triggered by dietary gluten in genetically predisposed individuals and the treatment is a strict gluten-free diet. The major predisposing genes are HLA-DQA1 and HLA-DQB1, but these are not sufficient for disease development. One of the candidate genes worth studying is interleukin (IL)-15 gene, together with its specific receptor, IL-15Rα, as they participate in promoting lymphocyte signaling and survival, and the establishment of appropriate conditions for villous atrophy, then acting as key players in the immunopathogenesis of CD...

HECT domain and RCC1-like domain-containing protein 5 (HERC-5) is one of the novel host restriction factors that is known to inhibit HIV release in vitro. Polymorphisms in other host restriction factors have been associated with HIV infection and disease progression. However, no report is available on the HERC-5 polymorphism in HIV-infected individuals. We studied the HERC-5 gene polymorphism in HIV-infected individuals and explored whether it is associated with different disease outcomes. Genomic DNA was isolated from 41 HIV-1 progressors, 39 long-term nonprogressors, and 74 HIV seronegative healthy donors for amplification of HERC5 Exon-18 and other regulatory regions followed by sequencing...

Oxidation of [Pt((II))Cl(terpy)](+) (terpy = 2,2':6',2''-terpyridine) has been attempted with several oxidizing agents and under different experimental conditions in order to obtain a Pt(iv) complex suitable for the conjugation to nanovectors to be used in drug delivery targeting for anticancer therapy. The best compromise in terms of yield and purity of the final complex was obtained by microwave-assisted reaction at 70 °C in 50% aqueous H2O2 for 2 h. Under these conditions the quantitative formation of [Pt((IV))Cl(OH)2(terpy)](+) was observed...

Genomic prediction utilizing causal variants could increase selection accuracy above that achieved with SNPs genotyped by currently available arrays used for genomic selection. A number of variants detected from sequencing influential sires are likely to be causal, but noticeable improvements in prediction accuracy using imputed sequence variant genotypes have not been reported. Improvement in accuracy of predicted breeding values may be limited by the accuracy of imputed sequence variants. Using genotypes of SNPs on a high-density array and non-synonymous SNPs detected in sequence from influential sires of a multibreed population, results of this examination suggest that linkage disequilibrium between non-synonymous and array SNPs may be insufficient for accurate imputation from the array to sequence...

Non-syndromic congenital cleft lip and jaw (CLJ) is a condition reported in Vorderwald × Montbéliarde cattle. The objective of the present study was to perform a genome-wide association study (GWAS) for 10 CLJ-affected and 50 unaffected Vorderwald × Montbéliarde cattle using the bovine Illumina high density bead chip to identify loci for this condition. Phenotypic classification of CLJ was based on a detailed recording of orofacial structures using computed tomography. A breeding experiment among CLJ-affected Vorderwald × Montbéliarde cattle and CLJ-affected Vorderwald × Montbéliarde cattle with unaffected Holsteins confirmed recessive inheritance and different loci for bilateral or left-sided versus right-sided CLJ...

Pythium myriotylum is responsible for severe losses in both capsicum and ginger crops in Australia under different regimes. Intraspecific genomic variation within the pathogen might explain the differences in aggressiveness and pathogenicity on diverse hosts. In this study, whole genome data of four P. myriotylum isolates recovered from three hosts and one P. zingiberis isolate were derived and analysed for sequence diversity based on single nucleotide polymorphisms (SNPs). A higher number of true and unique SNPs occurred in P...

Staphylococcus aureus bloodstream infections (SABSI) are associated with high morbidity and mortality. The Toll-like receptor 2 (TLR2) and Toll-interacting protein (TOLLIP) are important in recognition and regulation of human innate immunity response to S. aureus. Single nucleotide polymorphisms (SNPs) in the TLR2 and TOLLIP encoding genes have been associated with disease, including BSI. The aim of this study was to examine potential associations between a selection of SNPs in the genes encoding TLR2 and TOLLIP, and predisposition, severity, and outcome of SABSI...

It is of substantial interest to study the effects of genes, genetic pathways, and networks on the risk of complex diseases. These genetic constructs each contain multiple SNPs, which are often correlated and function jointly, and might be large in number. However, only a sparse subset of SNPs in a genetic construct is generally associated with the disease of interest. In this article, we propose the generalized higher criticism (GHC) to test for the association between an SNP set and a disease outcome. The higher criticism is a test traditionally used in high-dimensional signal detection settings when marginal test statistics are independent and the number of parameters is very large...

BACKGROUND: Individual differences in the pharmacokinetics (PK) of tacrolimus (TAC), an immunosuppressive drug, are reportedly associated with single-nucleotide polymorphisms (SNPs) of cytochrome P450 (CYP) 3A5 and multidrug resistance protein 1 (MDR1). We determined the effect of SNPs in CYP3A5 and MDR1 exons 21 and 26 on TAC PK parameters. METHODS: Thirty-eight Japanese patients who underwent renal transplantation were genotyped for CYP3A5 and exons 21 and 26 of MDR1 with the use of polymerase chain reaction-restriction fragment length polymorphism analysis...

Buffalo (Bubalus bubalis) is an important livestock species in many tropical and subtropical regions. In recent decades, the interest in buffalo's milk have expanded and intensive buffalo farms start to emerge. However, breeding programs and population genetics information for this species is scarce or inexistent. The present study aims to test the suitability of the commercial high-density single nucleotide polymorphisms (SNP) genotyping panel, the Illumina BovineHD BeadChip, to estimate population genetics parameters, pedigree control and identification of common variants in major production candidate genes...

Functional phenotypes (e.g., subcortical surface representation), which commonly arise in imaging genetic studies, have been used to detect putative genes for complexly inherited neuropsychiatric and neurodegenerative disorders. However, existing statistical methods largely ignore the functional features (e.g., functional smoothness and correlation). The aim of this paper is to develop a functional genome-wide association analysis (FGWAS) framework to efficiently carry out whole-genome analyses of functional phenotypes...

Microphthalmia-associated transcription factor (MITF) regulates the transcription of its target genes by binding to their promoters. In this study, an MITF gene, MpMITF was identified in the clam Meretrix petechialis. The full-length cDNA of MpMITF is 3564 bp with an ORF of 1365 bp. The deduced amino acid sequence consists of a conserved functional structure of bHLH-LZ, which could bind with E-box. The mRNA and protein expression levels of MpMITF were significantly up-regulated 6 h post-Vibrio injection. The mRNA expression of MpMITF increased on day 2 and peaked on day 10 post-Vibrio immersion...

Nicotine is the main component of cigarettes that causes addiction, which is considered a complex disease, and genetic factors have been proposed to be involved in the development of addiction. The CYP2A6 gene encodes the main enzyme responsible for nicotine metabolism. Depending on the study population, different genetic variants of CYP2A6 associated with cigarette smoking have been described. Therefore, we evaluated the possible association between SNPs in CYP2A6 with cigarette smoking and nicotine addiction-related variables in Mexican mestizo smokers...

Isolates of the Mycobacterium tuberculosis lineage 2/East-Asian are considered one of the most successful strains due to their increased pathogenicity, hyper-virulence associated with drug resistance, and high transmission. Recent studies in Colombia have shown that the Beijing-like genotype is associated with multidrug-resistance and high prevalence in the southwest of the country, but the genetic basis of its success in dissemination is unknown. In contribution to this matter, we obtained the whole sequences of six genomes of clinical isolates assigned to the Beijing-like genotype...
