We demonstrate here that histologically similar tumors with a proposed different genetic etiology can be differentiated based upon their genomic profiles using array CGH as an effective method to generate informative profiles in a genome-wide manner.
The genetic background of the four selected TGMS lines was examined by using a genomic SNP array, RICE6K.
We used a genomic tiling array to draw a transcriptomic atlas of Oryza sativa japonica (rice) mitochondria, which was predicted to be approximately 490-kb long.
The modulation of transcriptional profiles of S. aureus strains ATCC 29213, MRSA N315, SHY97-4320 and SHY97-3406 by the cranberry product NC90 was first evaluated by exploratory transcriptional profiling experiments using a sub-genomic array as described previously (in detail) [ 27, 28].
We have characterized the pathological and mutational landscape, and the clinical course of 6 new MDS patients with jumping mutations using chromosome genomic array testing (CGAT) and target gene panel next generation sequencing.
In the current study, DNA extracted from 20 formalin fixed paraffin embedded (FFPE) tissue samples from newly diagnosed cases of invasive ductal carcinoma referred to our laboratory with unresolved HER2 status, were analyzed using a clinically validated genomic array containing 127 probes covering the HER2 amplicon, the pericentromeric regions, and both chromosome 17 arms.
We then profile nine different normal tissues from two human donors relative to spleen using a custom array of genomic clones covering the euchromatic portion of human chromosome 1 and representing 8% of the human genome.
Test and reference polymerase chain reaction products were labeled by random priming with Cy3- and Cy5-dCTP (GE Healthcare, Buckinghamshire, UK), respectively, using a BioPrime array CGH genomic labeling system (Invitrogen, Carlsbad, CA) and precipitated together with ethanol in the presence of Cot-I DNA.
The extent of the duplication was determined by array comparative genomic hybridization (array CGH) using a 244 K array (Agilent Technologies, Englewood, CO) according to the manufacturer's instructions.
Gains and losses of the genes identified in the cDNA microarray analysis were assessed using genomic array slides produced by the Microarray Facility at Health Enterprise Rikshospitalet-Radiumhospitalet, containing 5000 unique BAC clones (RPCI-11 library, Wellcome Trust Sanger Institute, Cambridge, UK) that covered the whole genome with a resolution of approximately 1 Mbp.
