Transcription profiling time series of human HeLa cells cultivated while sterol depleted from the medium

ABSTRACT: The aim of the experiment was to identify novel genes with relevance to cellular cholesterol metabolism. HeLa cells were cultivated while sterol was depleted from the medium by applying 2-Hydroxypropyl-cyclodextrin. RNA for expression profiling was isolated 3h, 4.5h and 6h after depletion.

Transcription profiling of human neuro-invasive pancreatic tumors engineered in-vitro compared to less invasive parental cells

Project description:Perineural invasion (PNI) is considered to be a specific path for the spread of pancreatic cancer cells and PNI is thought to be one of the important factors that determine local recurrence after resection. In addition PNI has been implicated in the pain syndrome that affects the majority of pancreatic ductal adenocarcinoma (PDAC) patients. Here we aimed to investigate the transcriptional differences between neuro-invasive tumors engineered in-vitro compared to less invasive parental cells. Two colour differential hybridisations were performed with human universal reference total RNA (Clontech, #636538).

Transcription profiling of human hepatic and pancreatic stellate cells obtained from tissues of chronic inflammation, and primary or metastatic cancers

Project description:Differences in the expression profile of hepatic and pancreatic stellate cells are investigated. Aim is to identify organ and disease specific transcriptome signatures of stellate cells, comparing hepatic and pancreatic stellate cells obtained from tissues of chronic inflammation, and primary or metastatic cancers of the pancreas. Tissues of chronic pancreatitis (n=6), pancreatic ductal adenocarcinoma (n=5), liver cirrhosis (n=5) and liver metastasis of pancreatic ductal adenocarcinoma (n=6) were collected and stellate cells were isolated by the outgrowth method. Using cDNA microarrays, differentially expressed genes are identified.

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 yeast TOP1 null strain bearing plasmids that express wild-type yeast Top1p or an inactive Y727F mutant enzyme and treated with camptothecin

Project description:To establish the effect of CPT in the regulation of global transcription in S. cerevisiae, we have used a yeast TOP1 null strain, JEL1Δtop1, bearing a low-copy number plasmid that expresses, under the control of the yeast TOP1 promoter, either a wild-type (wt) yeast Top1p (pCC10) or an inactive Y727F mutant enzyme (pAR7).We determined global transcript levels upon CPT treatments of JEL1Δtop1 cells expressing either a yeast wt or Y727F mutant Top1p.

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".
