Project description:Neuroendocrine tumors (NETs) often harbor loss-of-function mutations in Daxx gene. Daxx interacts with several partners to regulate cellular processes and gene expression. We used microarrays to detail the global gene expression change in Daxx knockout MEFs and identified up-regulated genes during this process.
Project description:Microarrays were used to examine the genome-wide expression in FIH null, VHL null and VHL/FIH double null MEFs. We used these data to analyze how deletion of FIH or VHL alone affects gene expression and if VHL and FIH have synergistic effects and differential selectivity on regulating gene expression.
Project description:In order to identify the effects of starvation on the MEFs wt trascriptome, we performed Affymetrix Gene-Chip hybridization experiments for the starved cells Transcriptome analysis of the starved MEFs wt cells
Project description:Using ATAC seq analysis, we showed that the MEFs with a knockout of Lmna gene (i.e., missing the lamin A/C nuclear scaffolding protein) (Lmna-/- MEFs) display a striking change in chromatin accessibility landscape (peak signals that are both up and down), both within and outside lamina-associated domains (LADs); moreover, there was a clear overrepresentation of peaks with a gain in chromatin accessibility (within and outside LADs) in the Lmna-/- MEFs, and within LADs compared to outside LADs.
Project description:The aim of the experiment was to analyse the gene expression differences between MEFs containing TAp73 or without TAp73, at basal levels in normal culture conditions, and upon treatment with hypoxia (by incubation in 1% oxygen) for 4 or 8 hrs. The analysis indicate that absence of TAp73 leads to changes in multiple cellular and biological processes.
Project description:We have used primary MEFs derived from wild type and E2F4 null mice growing asynchrounously in serum to generate a signature for E2F4 pathway activation. 10 wild type and 10 E2F4 null samples were each assayed using the Affymetrics Mouse Genome 430A 2.0 array. Keywords: Primary MEFs from wild type and E2F4 null mice
