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

ABSTRACT: 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.

Transcription profiling of wild type, MKK3 transfected and Ras transfected mouse fibroblasts which have invaded or not invaded through a separating membrane

Project description:Invasiveness of genetically modified cells is tested. Four cells lines (NIH3T3 untreated control; NIH-Ras positive control which is invasion +; NIH-MKK3actK4 and NIH-MKK3actATN, two constructs with MKK3 gene which shall be investigated for theit invasiveness). Cells on top as well as cells from bottom of separating membrane (those which had "invaded") form all 4 cell lines are collected and expression profiled. Aim is to find genes which are correlated to "invasion".

Transcription profiling of mouse aorta (whole or regions) from mice of different embryonic ages

Project description:In order to identify novel regulators of haematopoietic stem cell emergence in the mouse embryonic AGM region, 3 different types of gene expression comparisons were performed. In the first one, whole dorsal aortas from embryonic day (E) 11 embryos and E9 embryos were dissected, tissues from each time point were pooled and their expression profile compared (whole aorta (WA) E9 vs E11). 3 different pools/biological replicas were obtained for each time point, a dye swap was included in each experiment, a technical replicate was performed for each pool (including the dye swap) and 2 self-self hybridisation controls were included. In the second comparison, GFP+ cells were isolated by fluorescence-activated cell sorting from pooled E9 and E11 aortas from transgenic embryos that express GFP under the regulatory elements of the Ly-6A gene. We obtained one pool for each time point and compared their transcription profile (GFP E9 vs E11). This comparison also contained a dye swap and a technical replicate (also of the dye swap). In the third comparison, the E11 aorta was cut into 3 roughly equal parts. Pools were obtained of the middle region ("m") and the two outer regions, rostral and caudal, together ("r+c") and their expression profile compared (11AO m vs r+c). There was one pool of each population, and the experiment included a dye swap and a technical replicate (also of the dye swap) and one self-self hybridisation control. Isolated RNA was amplified by T7-mediated in vitro transcription, with one round for the first and the third comparison and two rounds for the second comparison (sorted GFP+ cells). Probes were labelled during the reverse transcription step. Within array normalisation was achieved with Lowess Smooth and between arrays with Z scores. ANOVA analysis identified differentially expressed genes and K means clustering was used to segregate them into upregulated and downregulated genes.

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.

Transcription profiling of prostate tumor cell line AT1 inocculated into rats and then subjected to carbon ion or photon radiation

Project description:In the present study approximately 1 to 2 mm3 prostate tumor AT1 was inoculated subcutaneously in the right hind leg of adult male Copenhagen rats. When the tumor diameter exceeded 15 mm, tumors of 5 and 4 rats were irradiated with carbon ion radiation of 37 or 16Gy respectively. Tumors of 5 other rats were irradiated with photon radiation of 37Gy. One animal irradiated with 37 Gy carbon ion radiation and one animal irradiated with photon radiation was sacrificed 12h, 30h, 72h, 7d and 14d after irradiation respectively. One animal irradiated with 16 Gy photon radiation was sacrificed 12h, 60h, 7d and 14d after irradiation respectively. Non-irradiated animals were sacrificed at 60h time point. Tumors were dissected and frozen in liquid nitrogen immediately. Total RNA from tumor material was isolated using the NucleoSpin RNA L kit (#740962.20, Macherey-Nagel). Differential gene expression analysis was performed on the Agilent whole rat genome Oligo Microarray (44k) platform by comparative two dye hybridisation with dye-swaps.

Transcription profiling of SET-2 deletion and wild type yeast on sense and anti-sense arrays

Project description:The presence of Set2-mediated methylation of H3K36 (K36me) correlates with transcription frequency throughout the yeast genome. K36me targets the Rpd3S complex to deacetylate transcribed regions and suppress cryptic transcription initiation at certain genes. Here, using a genome-wide approach, we report that the Set2-Rpd3S pathway is generally required for controlling acetylation at coding regions. When using acetylation as a functional read-out for this pathway, we discovered that longer genes and, surprisingly, genes transcribed at lower frequency exhibit a stronger dependency. Moreover, a systematic screen using high resolution tiling microarrays allowed us to identify a group of genes that rely on Set2-Rpd3S to suppress spurious transcripts. Interestingly, most of these genes are within the group that depend the same pathway to maintain a hypo-acetylated state at coding regions. These data highlight the importance of using the functional readout of histone codes to define the roles of specific pathways.
