Project description:Van Marck et al. (Cancer Research, 2005) published that overexpression of P-cadherin in a melanoma cell line promoted homo- and heterotypic cell-cell adhesion, induced an epitheloïd morphology, and impaired cancer cell invasion. Therefore, we wanted to compare the RNA expression profile between the empty vector control cells and the P-cadherin overexpression variant. This experiment could provide us with effector molecules of P-cadherin that mediate its anti-invasive function.

Project description:This study aims to use RNAseq to identify differentially expressed transcripts in human melanoma cells that over-express the cell surface protein, LRRN4CL, relative to empty-vector control cells, to provide mechanistic insight into how LRRN4CL over-expression confers enhanced pulmonary metastatic colonisation abilities.

Project description:Neural stem/progenitor cells were isolated from the lateral ventricle wall of 4-6 week-old CD1 mice and grown as neurospheres under low density culture conditions. Test cells were transduced with bicistronic retroviral constructs for the over-expression of Bmi1 together with eGFP, and control cells were transduced with an empty vector construct expressing eGFP only. To identify genes, which are regulated by BMI1 in neural stem/progenitor cells, the gene expression profiles of neurosphere cells over-expressing Bmi1 were compared empty vector control cells using Affymetrix Gene mouse ST1.0 arrays
Project description:Stress-induced HDAC8 activity has been determined to be a driver of a neural crest stem cell (NCSC)-like transcriptional state that increased the formation of melanoma brain metastases (MBM). RNA-Seq experiments were performed against forced HDAC8 expressing cells and empty vector containing melanoma cells to determine differences in gene expression for the HDAC8-induced NCSC-like transcriptional state.
Project description:To investigate the effects of ppIAPP-GFP expression and urolithin B treatment in the gene expression of Saccharomyces cerevisiae cells, we compared different cells: cells expressing the empty vector, cells expressing ppIAPP-GFP, cells expressing the empty vector treated with urolithin B, cells expressing ppIAPP-GFP treated with urolithin B
Project description:Membrane-bound transcription factor CREB3L1 undergoes Regulated Intramembrane Proteolysis (RIP) in response to Hepatitis C infection. RIP activates CREB3L1 so that it can prevent the growth of HCV infected cells through the action of downstream genes. We over-expressed a truncated form of CREB3L1 that does not require RIP to enter the nucleus. Cells over-expressing this truncated form were isolated by Fluorescence Activated Cell Sorting (FACS). We used microarray to determine the downstream genes of CREB3L1 in comparison to a flow sorted empty vector control.
Project description:To get insight into the mechanisms of MCL1-induced survival and transformation, we screened 41,000 human genes in a genome-wide gene expression profile analysis of MCL1 over-expressing B-NHL cells. Experiment Overall Design: Two-color (Cy5-CTP/ Cy3-CTP) microarray-based gene expression formats presenting high-density oligonucleotide probes printed on a single glass slide were used (Agilent technologies, Cat No# G4112A whole human genome 41K). Total RNAs from MCL1 over-expressing RAMOS RA-1 and Z-138 B-cells were labeled with Cy5-CTP, whereas RNAs from references (empty vector/ RAMOS RA-1 and empty vector/ Z-138 B-cells) were labeled with Cy3-CTP. After competitive hybridization [RNA-Cy5 from MCL1 over-expressing RAMOS RA-1 or MCL1 over-expressing Z-138 versus RNA-Cy3 from either empty vector/ RAMOS RA-1 or empty vector/ Z-138 respectively] gene expression data were pre-processed using Feature Extraction software and GEPAS tools (http://gepas.bioinfo.cipf.es/).
