(Submitter supplied) A BAC-array platform for comparative genomic hybridization was constructed from a library of 32,433 clones providing complete genome coverage, and evaluated by screening for DNA copy number changes in 11 breast cell lines (BT474, MCF7, HCC1937, SK-BR-3, L56Br-C1, ZR-75-1, MCF10A, JIMT1, MDA-MB-231, MDA-MB-361 and HCC2218). These were also characterized by gene expression analysis and found to represent all five recently described breast cancer subtypes using the ‘intrinsic gene set’ and centroid correlation. more...

(Submitter supplied) Transcriptomic profiling of human breast tumors. Genomic and expression profiling using 38K BAC array-CGH and Illumina HT-12 beadchips were performed on 53 invasive breast tumors to assess the impact of gene dosage on gene expression patterns and the effect of other mechanisms on transcriptional levels. Array-CGH results was validated by FISH using tumors showing 8p11-p12 DNA amplification and expression profiling was confirmed using qPCR for 11 transcripts. more...

(Submitter supplied) Genomic changes in chromosome 8 are commonly observed in breast cancer cell lines and tumors. Fine mapping of such genomic changes, and evaluation of associated expression changes, are expected to provide reagents for diagnosis, insights into understanding the disease, and open up avenues for novel therapeutic intervention. We made an effort to search for genes on chromosome 8 with altered copy number and expression. more...

(Submitter supplied) Lobular intraepithelial neoplasia grade 3 (LIN) is a recently recognized variant of intraepithelial lobular neoplasia of the breast composed of either uniform, generally small, cells (classic) with massive lobular distension, pleomorphic cells, signet-ring cells, or any cell type with necrosis. In contrast to classic forms of LIN, there is no consensus on therapeutic strategies for LIN3. In part this is due to the paucity of molecular data that could assist in defining the relationship of LIN3 to classic LIN and carcinomas. more...

(Submitter supplied) Ductal carcinoma in situ (DCIS) is a non-obligate precursor to invasive ductal carcinoma (IDC). Annotation of the genetic differences between the two lesions may assist in the identification of genes that promote the invasive phenotype. Matched IDC and DCIS showed highly similar copy number profiles (average of 83% of the genome shared) indicating a common clonal orgin although there is evidence that the DCIS continues to evolve in parallel with the co-existing IDC. more...

(Submitter supplied) The identification of lobular caricnoma in situ (LCIS) in a patient's specimen confers and appreciable increased risk of development of future invasive mammary carcinoma. However the study of LCIS presents a challenge as it is usually only recognized in fixed specimens and no good in vivo or in vitro models currently exist. Recent advances in high throughput genomics have made possible comprehensive copy number analysis of lesions such as this. more...
