Genome-wide maps of H3K27 state in transfected NIH3T3 cells.

ABSTRACT: Epigenetic H3k27me3 changes of mouse NIH3T3 cells comparing control NIH3T3 cells transfected with a pEFm6-BRAF with cells transfected with pEFm6-BRAFV600E. By obtaining over 30 Million bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of BRAF transfected. We find that global lysine 3 and lysine 27 trimethylation levels changed under the condition of activated ERK by BRAFV600E, and specific genes might be downregulated for the hight level of H3K27me3 induced by BRAFV600E

Gene expression profiles of NIH3T3 influenced by MARVELD1

Project description:To investigate biological function of MARVELD1, we have employed whole genome microarray expression profiling as a platform to analyze gene expression alternation influenced by MARVELD1. MARVELD1 stably transfected NIH3T3 and control vector cells were used to compare their gene expression profiling. Total RNA from MARVELD1 overexpressing NIH3T3 cells and control cells were extracted to analyze their gene expression profiles by using mouse whole genome expression microarray.

Whole Transcriptome analysis of Aurintricarboxylic acid treated NIH3T3 cells

Project description:Aurintricarboxylic acid (ATA) was identified as a potent inhibitor of the TAZ/TEAD transcriptional complex via a Alpha-LISA screen. We have previously demonstrated that a hyperfunctional form of TAZ, TAZ-CAMTA1, is sufficient to induce the development of a rare vascular sarcoma, Epithelioid Hemangioendothelioma. We have demonstrated that TAZ-CAMTA1 can similarly transform NIH3T3 cells to yield anchorage independent growth in vitro and this action requires the formation of a TAZ-CAMTA1/TEAD complex. To identify if ATA is able to inhibit the transcriptional action TAZ-CAMTA1/TEAD complex, whole transcriptomic analysis was performed on TAZ-CAMTA1 stably transfected NIH3T3 cells with or without ATA.

Gene regulation in Erbb2 transfected NIH3T3 cells after Azacytidine treatment

Project description:5-Azacytidine or 5-aza-2â??-deoxycytidine is a chemical analogue of the cytosine nucleoside used in DNA and RNA. Cells in the presence of 5-azacytidine incorporate it into DNA during replication and RNA during transcription. The incorporation of 5-azacytidine into DNA or RNA inhibits methyltransferase thereby causing demethylation in that sequence, affecting the way that cell regulation proteins are able to bind to the DNA/RNA substrate. Inhibition of DNA occurs through the formation of stable complexes between the molecule and with DNA methyltransferases, thereby saturating the cells methylation machinery. 5-azacytidine is mainly used in the treatment of myelodysplastic syndrome. Changes in gene expression levels in Erbb2 transfected murine fibroblast cell line after treatment with Azacytidine in two different concentrations were analysed. Keywords: cDNA microarray, murine fibroblast, azacytidine treatment, carcinogenesis Gene expression levels of Erbb2 transfected NIH3T3 cell lines treated with 5ÂµM and 10ÂµM Azacytidine were compared to Erbb2 transfected but non-treated NIH3T3 cell line. For each Azacytidine concentration 4-8 experiments were performed including 50% dye swaps. As a controll experiments gene expression levels of NIH3T3 cells with and without Azacytidine treatment were analysed
