Copy number alteration in Wilms' tumor with custom-designed miRNA probes

ABSTRACT: The aim of this study is to discover loss of specific miRNA loci in Wilms' tumors using array CGH. Custom arrays were designed based on the Agilent 2x105K Human Whole Genome Genomic microarray with Agilent’s eArray program (https://earray.chem.agilent.com/earray/), with additional probes that cover all miRNA regions (200 bps before, within and after each miRNA from miRBase v13, with each probe in triplicates to enhance the reliability). All custom-designed probes were designed in UCSC hg18. Probes from Agilent’s database were lifted-over from hg19 to hg18 (LiftOver tool: http://genome.ucsc.edu). The Agilent 2x105K custom-design whole genome microarray was used to analyze genomic alterations in Wilms' tumor samples compared to normal human genomic DNA (Promega p/n G1523).

Agilent_HGG_custom_CGH

Project description:Custom oligonucleotide array CGH. We designed two fine-tiling oligonucleotide microarrays to cover the specific amplicons observed at chromosome 2p22.1 and 10q11.21 This was undertaken using the Agilent custom array design tool e-Array (Agilent, Santa Clara, CA, USA; https://earray.chem.agilent.com/), and comprised 700 probes covering 43.56Ð43.70 Mb on chromosome 10 and 5000 probes covering 39Ð40 Mb on chromosome 10 with a median probe interval of 200 bp on 2x105K microarray. Due to limited amount of material, DNA was whole genome amplified (WGA) using the GenomePlex Complete Whole Genome Amplification Kit (Sigma, Gillingham, UK) starting with 10 ng of sample and control DNA, and following the manufacturers protocol. WGA DNA was labelled using the Agilent Genomic DNA ULS labelling kit, hybridised as per manufacturers instructions, and scanned on the Agilent 2505B Microarray Scanner System.

Sex specific gene expression patterns and array optimization in liver tissue of the Antarctic eelpout Pachycara brachycephalum

Project description:Custom Gene Expression Microarray, 2x105K. The array was designed based on a cDNA library of the Antarctic eelpout, Pachycara brachycephalum (BioProjectID PRJNA82979 / NCBI Sequence Read Achive SRA049761). It was built to test probes (if possible 6 probes are designed per sequence in the cDNAlibrary: 3 were spotted in sense, 3 others in antisense direction) for the generation of a compact species-specific custom array. As the cDNA library was composed of liver and heart transcriptomic sequences, we also included both tissues in this study. Here a we investigated sex-specific expression patterns in liver by hybridizing liver RNA against a reference pool composed of liver and heart RNA.

Investigating the effect of CodY mutation on the gene expression in Streptococcus suis serotype 2 SC19 strain.

Project description:To investigate the effect of CodY mutation on the gene expression in Streptococcus suis serotype 2 SC19 strain, we have employed whole genome microarray expression profiling as a discovery platform to identify genes regulated by CodY mutation. DNA microarray analysis was performed using an Agilent custom-designed oligonucleotide microarray. Based upon the whole genome sequence of SC19 , specific 60-mer oligonucleotide probes were designed using eArray (https://earray.chem.agilent.com/earray/), to cover all annotated genes. Probes were printed seven times on microarray slides. Three biological replicates of total RNA from two wild type strains and from two codY mutant strains were amplified and labeled with Cy3-CTP using Low Input Quick Amp Labeling Kit, one-color(Agilent technologies, US), following the manufacturer’s instructions. Labeled cRNA was purified using the RNeasy mini kit (Qiagen). After fragmentation, microarray slides were hybridized with 600 ng Cy3-labeled cRNA. Hybridization was performed at 65 °C for 17 h with rotation at 10 rpm. Microarray slides were washed and scanned by an Agilent Microarray Scanner (G2565BA). Those genes with greater than two-fold change ratios were regarded as differentially expressed genes.

DNA copy number variation from human Wilms' Tumor samples

Project description:Genome-wide DNA copy number was studied to determine whether the Wilms' tumor samples generally show normal copy number variation comparing to the colon tumor samples We used custom Nimblegen microarrays to determine the genome-wide DNA copy number in human Wilms' Tumor samples We isolated genomic DNA from human Wilms' tumor tissues and hybridized to custom-designed Nimblegen microarrays (CHARM arrays).

High-resolution custom array spanning Xq28 region to study patients carrying MECP2 copy number gain (part 1)

Project description:The goal of this experiment was to determine the size, genomic extent and gene content of each Xq28 rearrangement. We designed a tiling-path oligonucleotide microarray spanning 4.6 Mb surrounding the MECP2 region on Xq28. The custom 4x44k Agilent Technologies microarray was designed using the Agilent earray website. We selected 22,000 probes covering ChrX: 150,000,000-154,600,000 (NCBI build 36), including the MECP2 gene, which represents an average distribution of 1 probe per 209 bp. Each patient sample was run once using this array; hybridization was done using a gender-matched reference sample.

Genomic profiling of splenic marginal zone lymphoma (SMZL)

Project description:Array-based comparative genomic hybridization comparing splenic marginal zone lymphoma (SMZL) specimens with control DNA A custom high-definition oligonucleotide microarray (4x44K, Agilent) was designed for aCGH from the online application tool eArray (version 5.3) and HD-CGH probe library (sequence source UCSC hg18 / NCBI Build 36). This custom microarray combines the capability to scan human genome-wide with an average resolution of approximately 100 Kb and to focus on regions of interest for highest resolution tiling (11 Kb-resolution for either chromosomes 3q and 7q). The array contains about 8,500 and 9,000 oligonucleotides spanning 97 Mb and 105 Mb of the 7q and the 3q chromosomes respectively. Twenty-seven SMZL specimens (9 males, 18 females) were analyzed using a dye-swap methodology to confirm the copy number variations. Two samples (one male, one female, namely M-CTRL and F-CTRL) collected from healthy volunteers blood from national Etablissement FranM-CM-'ais du Sang were used as DNA reference for aCGH experiments.
