Project description:RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer may help doctors identify biomarkers related to cancer.
PURPOSE: This laboratory study is using gene expression profiling to evaluate normal tissue and tumor tissue from patients with colon cancer that has spread to the liver, lungs, or peritoneum.
Project description:Heterochromatin-protein 1 (HP1) is a functionally diverse family of proteins. In particular, Drosophila dHP1c forms a complex with the transcription factors WOC and ROW (dHP1EU) that localizes at euchromatin and regulates gene expression. We used microarrays to analyse the changes in gene expression after row depletion by RNAi.
Project description:H3K4me3 is a histone modification related to gene activation. LID is a demethylase acting on this residue and therefore, it could be important for proper expression of genes in Drosophila developing tissues, such as wing imaginal discs We used microarrays to analyse the changes in gene expression after lid depletion by RNAi, both in a wild type background and in a mutant background
Project description:Heterochromatin-protein 1 (HP1) is a functionally diverse family of proteins. In particular, Drosophila dHP1c forms a complex with the transcription factors WOC and ROW (dHP1EU) that localizes at euchromatin and regulates gene expression. We used microarrays to analyse the changes in gene expression after row depletion by RNAi. For expression profiling analyses, total RNAs were prepared from control S2 cells and upon RNAi-mediated depletion of ROW, converted to cDNA and hybridized to Drosophila Genome 2.0 GeneChip (Affymetrix).
