Design and evaluation of Actichip, a thematic microarray for the study of the actin cytoskeleton

open access: yesBMC Genomics, 2007
Background The actin cytoskeleton plays a crucial role in supporting and regulating numerous cellular processes. Mutations or alterations in the expression levels affecting the actin cytoskeleton system or related regulatory mechanisms are often ...

Bacterial artificial chromosome-emulation oligonucleotide arrays for targeted clinical array-comparative genomic hybridization analyses

open access: yesGenetics in Medicine, 2008
Purpose: The goal of this work was to test the ability of oligonucleotide-based arrays to reproduce the results of focused bacterial artificial chromosome (BAC)-based arrays used clinically in comparative genomic hybridization experiments to detect ...

MicroRNA Expression Profiling by Bead Array Technology in Human Tumor Cell Lines Treated with Interferon-Alpha-2a

open access: yesBiological Procedures Online, 2009
MicroRNAs are positive and negative regulators of eukaryotic gene expression that modulate transcript abundance by specific binding to sequence motifs located prevalently in the 3' untranslated regions of target messenger RNAs (mRNA). Interferon-alpha-2a

NOTCH2 is neither rearranged nor mutated in t(1;19) positive oligodendrogliomas. [PDF]

open access: yesPLoS ONE, 2009
The combined deletion of 1p and 19q chromosomal arms is frequent in oligodendrogliomas (OD) and has recently been shown to be mediated by an unbalanced t(1;19) translocation.

Thermodynamics of RNA/DNA hybridization in high density oligonucleotide microarrays [PDF]

open access: yesPhysica A 362, 433 (2006), 2004
We analyze a series of publicly available controlled experiments (Latin square) on Affymetrix high density oligonucleotide microarrays using a simple physical model of the hybridization process. We plot for each gene the signal intensity versus the hybridization free energy of RNA/DNA duplexes in solution, for perfect matching and mismatching probes ...

Secondary structure in the target as a confounding factor in synthetic oligomer microarray design

open access: yesBMC Genomics, 2005
Background Secondary structure in the target is a property not usually considered in software applications for design of optimal custom oligonucleotide probes.

DNA sequence correlations shape nonspecific transcription factor-DNA binding affinity [PDF]

open access: yesBiophys. J. 101(1), 160-166 (2011), 2011
Transcription factors (TFs) are regulatory proteins that bind DNA in promoter regions of the genome and either promote or repress gene expression. Here we predict analytically that enhanced homo-oligonucleotide sequence correlations, such as poly(dA:dT) and poly(dC:dG) tracts, statistically enhance non-specific TF-DNA binding affinity.

Strong position-dependent effects of sequence mismatches on signal ratios measured using long oligonucleotide microarrays

open access: yesBMC Genomics, 2008
Background Microarrays are an important and widely used tool. Applications include capturing genomic DNA for high-throughput sequencing in addition to the traditional monitoring of gene expression and identifying DNA copy number variations.
