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
Project description:Multiple endocrine neoplasia type1 (MEN1), an inherited autosomal dominant syndrome characterized by the development of endocrine tumors including NETs, results from mutation in the MEN1 gene that encodes the protein menin. In mouse models, heterozygous loss of Men1 leads to multiple endocrine tumors with loss of heterozygocity at the Men1 locus. Men1 interacts with several partners to regulate cellular processes and gene expression through regulating histone modification. We used microarrays to detail the global gene expression change in Men1 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. To assess how deletion of FIH, VHL and both VHL and FIH affect gene expression genome-widely, we generated FIH null, VHL null and VHL/FIH double null MEFs after adeno-cre virus infection on large T-immortalized FIHdf, VHLdf, and VHLdf/FIHdf MEFs. These MEFs were cultured under normoxia (21% O2) with complete culture medium before RNA extraction. Total RNA were isolated by using Qiagen RNeasy kit and treated with on-column DNase digestion. Affymetrix GeneChip Mouse Genome 430 2.0 Array was used.
