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

ABSTRACT: 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 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 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.

AngioEvasion_001

Project description:We aim to identify the molecular mechanisms underlying LLC tumor evasion from endogenous angiogenesis inhibitor Endostatin in-vivo. Tumor cells were inoculated in C57/BL6 mice. Mice were treated with muFc-endostatin (20ﾵg/day) until the tumors evade therapy. Tumors were re-implanted in a new batch of mice for 4 consecutive in-vivo passages. Passage four (P4) endostatin-treated and control tumors were profiled. Significantly upregulated genes attributed to endostatin resistance were identified. Their gene expression levels were assessed by real-time PCR (Taqmanﾮ probe). Candidate genes were further functionally evaluated in-vivo using inhibitors.

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.
