5q21 tiling array on prostate tumors

ABSTRACT: CGH profiles of prostate tumors on custom designed high resolution arrays tiling chromosome 5q21 A custom high-density Agilent 15k CGH array tiling 5q21 was designed to narrow down the region of deletion at 5q21 to a few genes that could be followed up with functional studies. 8 critical prostate tumors samples with the most focal regions of deletion were chosen to be profiled on the 5q21 tiling array.

Recurrent deletion of CHD1 in prostate cancer with relevance to cell invasiveness.

Oncogene 20111219 37

Though prostate cancer is often indolent, it is nonetheless a leading cause of cancer death. Defining the underlying molecular genetic alterations may lead to new strategies for prevention or treatment. Towards this goal, we performed array-based comparative genomic hybridization (CGH) on 86 primary prostate tumors. Among the most frequent alterations not associated with a known cancer gene, we identified focal deletions within 5q21 in 15 out of 86 (17%) cases. By high-resolution tiling array CG ...[more]

aCGH profiling of prostate tumors

Project description:This experiment was an aCGH study on 86 prostate tumors samples. The samples were profiled on Agilent Human Genome 44karrays to identify recurrent regions of deletion and amplification, thus revealing potential new tumor suppressor genes and/or oncogenes involved in prostate cancer. The CGH profile on the 44k arrays revealed a deletion at 5q21 in 17% of samples. CGH analysis of 86 prostate tumor samples.

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

Project description: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).

High-density deletion bin map of wheat chromosome 7B

Project description:Using 270K Nimblegen Comparative Genomic Hybridization (CGH) array on a set of cv. Chinese Spring deletion lines, a total of 3,671 sequence contigs and scaffolds (~7.8% of chromosome 7B physical length) were mapped into nine deletion bins. In our study we have developed 270K CGH Nimblegen array containing wheat 7B chromosome specific probes and genotyped wheat 7B deletion stocks which have terminal deletions in 7B. Our main aim was to identify absent probes (sequences) in deletion lines. Initially, spatial normalization and M-A loess normalization was performed for comparison test/reference and then clustering analysis (Mcust) was carried out. Further analysis was done on scaffolds (i.e. on larger sequences instead of probes; probes are designed from scaffolds) Hybridization of DNA from 13 wheat lines, including 11 Chinese Spring cytogenetic stocks (Del7BL-9, DT7BL, DT7BS, Del7BL-13, Del7BL-14, Del7BL-5, Del7BL-1, Del7BL-7Del1DS-3, Del7BL-2,Del7BS-2, Del7BL-3) and 2 replicates of Langdon (LDN) tetraploid wheat. A set of 49,500 7B chromosome specific features (ISBP probes and random genomic features) and 18,000 control probes with each probe replicated four times on the 270K chip.

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.

Biosafety circuits for Mycoplasma - DNA-seq for passages 2, 3 and 15 of clonal Mycoplasma pneumoniae biosafety strains to study long-term stability of kill-switch devices

Project description:We have engineered synthetic gene switches to control and limit Mycoplasma growth for biosafety containment applications. Mycoplasmas have high mutation rates and, the accumulation of mutations that inactivate the circuit is expected. However, the question is how resilient is the kill-switch to mutation and whether it is more sensitive to the accumulation of mutations. Therefore, we did the whole-genome sequencing of the three Mycoplasma biosafety strains, designed in our study, at different passages (p2, p3 and p15) or after IPTG-treatment at passage 3 (p3IPTG)

The Condition-Dependent Transcriptional Landscape of Burkholderia pseudomallei

Project description:Bacterial transcriptomes are dynamic, context-specific and condition-dependent. Infection by the soil bacterium, Burkholderia pseudomallei, causes melioidosis, an often fatal infectious disease of humans and animals. Possessing a large multi-chromosomal genome, B. pseudomallei is able to persist and survive in a multitude of environments. To obtain a comprehensive overview of B. pseudomallei expressed transcripts, we initiated whole-genome transcriptome profiling covering a broad spectrum of conditions and exposures M-bM-^@M-^S a so-called M-bM-^@M-^\condition compendiumM-bM-^@M-^]. Using the compendium, we confirmed many previously-annotated genes and operons, and also identified hundreds of novel transcripts including anti-sense transcripts and non-coding RNAs. By systematically examining genes exhibiting highly similar expression patterns, we ascribed putative functions to previously uncharacterized genes, and identified novel regulatory elements controlling these expression patterns. We also used the compendium to elucidate candidate virulence pathways associated with quorum-sensing and infection in mice. Our study showcases the power of a B. pseudomallei condition compendium as a valuable resource for understanding microbial physiology and the pathogenesis of melioidosis. The transcriptome profiles of Bp exposed to 82 conditions were captured using a custom-designed tiling microarray and compiled into a compendium revealing novel genomic features and co-expression network.
