Comparative genomic hybridization of 30 ovarian cancer cell lines reveals amplification of PVT1 contributes to the pathophysiology of ovarian and breast cancer

ABSTRACT: DNA from 30 cultured ovarian cancer cell lines was extracted with Promega kits and hybridize to arrays. Arrays comprised of 1860 BACs selected to include genes known to be involved in cancer pathogenesis and 400 BACs selected to tile across 13 Mbp at 3q26, 15 Mbp at 8q24, and 30 Mbp at 20q centered on regions of recurrent amplification associated with reduced survival duration.

<h4>Purpose</h4>This study was designed to elucidate the role of amplification at 8q24 in the pathophysiology of ovarian and breast cancer because increased copy number at this locus is one of the most frequent genomic abnormalities in these cancers.<h4>Experimental design</h4>To accomplish this, we assessed the association of amplification at 8q24 with outcome in ovarian cancers using fluorescence in situ hybridization to tissue microarrays and measured responses of ovarian and breast cancer ce ...[more]

Transcription profiling of human carcinoma in situs cells from testis compared to fetal gonocytes, oogonia and cultured embryonic stem cells

Project description:Abstract: Testicular cancers in young adult men derive from an inborn precursor lesion, called carcinoma in situ (CIS) of the testis. CIS cells are believed to arise from primordial germ cells or gonocytes that fail to differentiate into the male germ cell lineage, and show a remarkable resemblance to embryonic stem cells (ESC). With this study we aimed at further elucidating the origin of CIS using microarray analysis of genome-wide gene expression. CIS cells only constitute a small fraction of the tissue and therefore, to reduce contaminating RNA from other cell types, we developed a fast (160 sec) staining procedure specific for CIS and fetal germ cells. Highly enriched cell populations were obtained by laser microdissectioning. The expression profiles of CIS cells were compared to microdissected fetal gonocytes, oogonia and cultured ESC with and without genomic amplifications. The cell type most similar to CIS was the gonocytes indicating malignant transformation at this stage. The enriched cell populations allowed us to find unique expression patterns for the developmentally very related cell types. Analyses of the similarities and differences among the cell types may help us understand when and how the malignant transformation to CIS occurs.

siRNA profiling of human synovial fibroblasts depleted for clusterin

Project description:Analysis of synoviocytes cell form patients suffering of Rheumatoid arthritis and depleted for clusterin by siRNA knockdown. Note: this experiment was reloaded into ArrayExpress on 2nd December 2009 because the incorrect array design had originally been selected. The identifiers in the datafile were also fixed to match the array design.

CGH data from 58 bladder tumors

Project description:We present the first computational approach to reconstruct the sequence of copy number alterations driving carcinogenesis from the analysis of several tumor samples of a same patient. Applied to BAC array-CGH and SNP array data from bladder and breast cancers, this method proved highly valuable to establish the clonal relationships between primary tumors and recurrences and to identify the chromosome aberrations at the initiation of tumorigenesis. Keywords: Comparative Genomic Hybridization An algorithm was developed to reconstruct tumors lineage and the sequence of copy number alterations along tumorigenesis from the analysis of several samples from a same patient. The data here consist in CGH data from 58 bladder tumors. 50 of these tumors come from independent samples and were used to compute the frequencies of breakpoints at each location. The 8 other samples (S1_A, S1_B, S2_A, S2_B, S3_A, S3_B, S3_C and S3_D) are multiple tumors from 3 patients. They were used to reconstruct the sequence of chromosome aberrations along cancer development in these 3 patients.

Transcription profiling of human blood from patients with acute kidney injury following open-heart surgery with cardiopulmonary bypass

Project description:Acute kidney Injury (AKI) following open-heart surgery with cardiopulmonary bypass (CPB) is associated with an increased morbidity and mortality. The goal of this study is to explore patterns of gene expression in human AKI following CPB. This prospective observational study was approved by the Institutional Review Board Human Subjects Committee. Design and methods: Peripheral blood RNA samples were collected prospectively from a cohort of 30 patients at Caritas St. Elizabeths Medical Center in Boston, MA, undergoing CPB at time points immediately prior, and two and 24 hours following CPB. Gene expression patterns of four patients who developed AKI (cases) following CPB will be compared with six patients matched for clinical characteristics, who did not develop AKI (controls). AKI was defined by an incremental increase in serum creatinine of 30% within 72 hours following CPB. For peripheral blood RNA sampling, 2.5 ml of venous whole blood was collected into PAXgene Blood RNA Tube collection tubes (PreAnalytiX GmbH, Hombrechtikon, CH). Whole blood RNA was extracted with the PAXgene Blood RNA extraction Kit according to the manufacturers instructions (PAXgene RNA Kit Handbook, 06/2005). All biological samples are stored at 80° C.

Improvement of Lactobacillus plantarum Aerobic Growth by Comprehensive Transcriptome Analysis

Project description:An aerobic Lactobacillus plantarum culture displayed growth stagnation during early growth. Transcriptome analysis revealed that regain of growth after stagnation correlated with activation of CO2-producing pathways suggesting that limiting CO2-concentration induced stagnation. Analogously providing increased CO2 gas partial pressure during aerobic fermentation prevented the temporal growth stagnation. Keywords: cell type comparison Two aerobic fermenters (biological replicates Land R) were sampled at two time points, before (1) and after (2) growth stagnation.
