In Escherichia coli, repression of the aceBAK operon is mediated by the IclR protein. We used an in vitro oligonucleotide selection technique to determine the consensus recognition sequence for MR. Mutational analysis confirmed the contribution of this sequence to repression in vivo and identified the -35 element of the promoter.

We have developed a methodology we call ROMA (representational oligonucleotide microarray analysis), for the detection of the genomic aberrations in cancer and normal humans. By arraying oligonucleotide probes designed from the human genome sequence, and hybridizing with "representations" from cancer and normal cells, we detect regions of the genome with altered "copy number." We achieve an ave...

Copy-number variants (CNVs) occur frequently within the human genome, and may be associated with many human phenotypes. If disease association studies of CNVs are to be performed routinely, it is essential that the copy-number status be accurately genotyped. We systematically assessed the dynamic range response of an oligonucleotide microarray platform to accurately predict copy-number in a set...

Well-defined relationships between oligonucleotide properties and hybridization signal intensities (HSI) can aid chip design, data normalization and true biological knowledge discovery. We clarify these relationships using the data from two microarray experiments containing over three million probes from 48 high-density chips. We find that melting temperature (T(m)) has the most significant eff...

Cornelia de Lange syndrome (CdLS) is a genetically heterogeneous disorder characterized by growth retardation, intellectual disability, upper limb abnormalities, hirsutism, and characteristic facial features. In this study we explored the occurrence of intragenic NIPBL copy number variations (CNVs) in a cohort of 510 NIPBL sequence-negative patients with suspected CdLS. Copy number analysis was...

in this paper, we generalize a theorem of shao [12] by assuming that is a sequence of linear negatively dependent random variables. also, we extend some theorems of chao [6] and thrum [14]. it is shown by an elementary method that for linear negatively dependent identically random variables with finite -th absolute moment the weighted sums converge to zero as where and is an array of real numbe...

MOTIVATION DNA arrays are a very useful tool to quickly identify biological agents present in some given sample, e.g. to identify viruses causing disease, for quality control in the food industry, or to determine bacteria contaminating drinking water. The selection of specific oligos to attach to the array surface is a relevant problem in the experiment design process. Given a set S of genomic ...

mycoplasma synoviae expressed variable lipoprotein haemagglutinin (vlha) is believed to play a major role in pathogenesis of the disease by mediating adherence and immune evasion. the aim of this study was sequencing iranian m. synoviae isolates for the detection of nucleotide variation in the m. synoviae vlha gene. using oligonucleotide primers complementary to the single-copy conserved 5´ end...

Background: This study aimed to design and analyze the applicability of an oligonucleotide probe in radioisotope 32P-based dot blot hybridization for detection of hepatitis C virus. Methods: Forty-six of plasma samples were used. The plasma was extracted to obtain viral RNA genome as template for RT-PCR and the amplicon was used for nested PCR. Twenty-four HCV genomes were retrieved from GeneBa...
