Genomic Alterations in Breast Cancer Subtypes Array Comparative Genomic Hybridization Analysis of Updated Version
In this study, we performed high-resolution array comparative genomic hybridization with an array of 4153 bacterial artificial chromosome clones to assess copy number changes in 44 archival breast cancers. The tumors were flow sorted to exclude non-tumor DNA and increase our ability to detect gene copy number changes. In these tumors, losses were more frequent than gains, and gains in 1q and lo...

متن کاملGenetic alterations in lobular breast cancer by comparative genomic hybridization.
Infiltrating lobular carcinoma (ILC) and infiltrating ductal carcinoma (IDC) are distinguished by their histopathological appearance. However, little is known about the differences in genetic changes between lobular cancers and ductal cancers. We used comparative genomic hybridization (CGH) and compared aberrations in 19 ILCs and 46 IDCs. The total number of aberrations was lower in ILC than in...
متن کاملIdentification of Genomic Alterations in Pancreatic Cancer Using Array-Based Comparative Genomic Hybridization
BACKGROUND Genomic aberration is a common feature of human cancers and also is one of the basic mechanisms that lead to overexpression of oncogenes and underexpression of tumor suppressor genes. Our study aims to identify frequent genomic changes in pancreatic cancer. MATERIALS AND METHODS We used array comparative genomic hybridization (array CGH) to identify recurrent genomic alterations an...
متن کاملGenomic alterations detected by comparative genomic hybridization in ovarian endometriomas.
Endometriosis is a complex and multifactorial disease. Chromosomal imbalance screening in endometriotic tissue can be used to detect hot-spot regions in the search for a possible genetic marker for endometriosis. The objective of the present study was to detect chromosomal imbalances by comparative genomic hybridization (CGH) in ectopic tissue samples from ovarian endometriomas and eutopic tiss...
