ABSTRACT: DNA copy number profiling for all primary tumor samples and cell lines was performed by ROMA, a form of comparative genomic hybridization. The aim was to identify commonly amplifiied and deleted regions. 538 primary tumor samples and 253 human cell lines were analyzed.
Project description:DNA copy number profiling for all primary tumor samples and HCC cell lines was performed by ROMA, a form of comparative genomic hybridization. The aim was to identify commonly amplifiied and deleted regions across human HCC. 88 primary HCC samples and 12 human HCC cell lines were analyzed.
Project description:The following CGH experiments were conducted on four sectors (S1-S4) from a single primary ductal carcinoma tumor (T16) using the Sector-Ploidy-Profiling (SPP) Approach. SPP involves macro-dissecting the tumor, flow-sorting nuclei by differences in total genomic DNA content and profiling the genome of the tumor subpopulations. The genomic DNA from each tumor subpopulation was labeled with Cy5 and hybridized to an 390K Rubble-Rep ROMA Microarray. A normal reference male fibroblast was labeled with Cy3 as a control. Samples were cohybridize to the same single microarray.
Project description:Distinct molecular subtypes of breast carcinomas have been identified, but translation into clinical use has been limited. We have developed two platform independent algorithms to explore genomic architectural distortion using array comparative genomic hybridization (aCGH) data to measure 1) whole arm gains and losses (WAAI) and 2) complex rearrangements (CAAI). By applying CAAI and WAAI to data from 595 breast cancer patients we were able to separate the cases into eight subgroups with different distribution of genomic distortion. Within each subgroup data from expression analyses, sequencing and ploidy indicated that progression occurs along separate paths into more complex genotypes. Histological grade had prognostic impact only in the Luminal related groups while the complexity identified by CAAI had an overall independent prognostic power. This study emphasizes the relationship between structural genomic alterations, molecular subtype and clinical behavior, and provides a score of genomic complexity as a new tool for prognostication in breast cancer. Array CGH of 255 breast tumor samples vs a male skin fibroblast reference sample, in color reversal.
Project description:The following CGH experiments were conducted on six sectors (S1-S6) from a single primary ductal carcinoma tumor (T13) using the Sector-Ploidy-Profiling (SPP) Approach. SPP involves macro-dissecting the tumor, flow-sorting nuclei by differences in total genomic DNA content and profiling the genome of the tumor subpopulations. The genomic DNA from each tumor subpopulation was labeled with Cy5 and hybridized to an 85K Bgl2 ROMA Microarray. A normal reference male fibroblast was labeled with Cy3 as a control. Samples were dye-swapped and the experiments were conducted in color-reversal. The value data repesents a log ratio of the mean of two dye-swapped samples
