background rapid detection of resistant strains of helicobacter pylori in human clinical samples is of major importance in clinical settings. inability of conventional clinical laboratory techniques in detection of these strains usually leads to failure of prescribed therapeutic regimens. objectives the aim of this study was designing a simple and rapid allele-specific pcr (as-pcr)-based method...
The Pyrus species exhibit the gametophytic self -incompatibility which is considered to be the most widespread self-incompatibility system among flowering plants. This system prevents self-fertilization through a specific pollen-pistil recognition mechanism. The S-allele diversity in the Iranian genotypes indicates that the pear germplasm of Iran can be an excellent source of variability for br...
The extent to which variation in chromatin structure and transcription factor binding may influence gene expression, and thus underlie or contribute to variation in phenotype, is unknown. To address this question, we cataloged both individual-to-individual variation and differences between homologous chromosomes within the same individual (allele-specific variation) in chromatin structure and t...

We have developed an optimized array-based approach for customizable allele-specific gene expression (ASE) analysis. The central features of the approach are the ability to select SNPs at will for detection, and the absence of need to PCR amplify the target. A surprisingly long probe length (39-49 nt) was needed for allelic discrimination. Reconstitution experiments demonstrate linearity of ASE...
MOTIVATION Expression quantitative trait loci (eQTL) studies have discovered thousands of genetic variants that regulate gene expression, enabling a better understanding of the functional role of non-coding sequences. However, eQTL studies are costly, requiring large sample sizes and genome-wide genotyping of each sample. In contrast, analysis of allele-specific expression (ASE) is becoming a p...
From the accompanying paper (Djansugurova et al., 2013), it is clear that cancer screening is making a global impact in reducing cancer mortality, a major advance that will increase in value as more therapeutic regimens become available on a worldwide basis. The genes of value are ones in which specific alleles are statistically related to oncogenesis. The major arbitrary element is a potential...
Members of the kinesin superfamily are force-generating ATPases that drive movement and influence cytoskeleton organization in cells. Often, more than one kinesin is implicated in a cellular process, and many kinesins are proposed to have overlapping functions. By using conventional kinesin as a model system, we have developed an approach to activate or inhibit a specific kinesin allele in the ...
We present an allele-specific copy number analysis of the in vivo breast cancer genome. We describe a unique bioinformatics approach, ASCAT (allele-specific copy number analysis of tumors), to accurately dissect the allele-specific copy number of solid tumors, simultaneously estimating and adjusting for both tumor ploidy and nonaberrant cell admixture. This allows calculation of "ASCAT profiles...
