Project description:Whole transciptome analysis of colon cancer mutated cell lines(HCT116 and DLD1) under serum starvation conditions (19hrs-0.5%FBS) We used microarrays to compare gene regulation of truncated cell lines, knocked-out of either the wild type or mutated allele of PI3K, for two independent colon cancer cell lines
Project description:MicroRNA profiling in colon cancer cell lines. Two cell lines have been found with impairment on the export of precursor miRNAs into the cytoplasm (XPO5), HCT15 and DLD1. To test the microRNAs involved several comparisons have been performed: DLD1 and HCT15 cell lines have been compared with XPO5 wild-type cell lines (HCT116 and RKO). Furthermore the transfected XPO5 wild-type defective cells (DLD1.XPO5 wt and HCT15.XPO5 wt) have been compared respect to the non-transfected cells (HCT15 and DLD1). Finally the cell lines HCT15 and DLD1 transfected with a negative control (HCT15.XPO5 358-366 and DLD1.XPO5 358-366) have been compared with respect to non-transfected cell lines (HCT15 and DLD1).

Project description:To investigate the function of Atoh1 in colon cancer cells. We have employed whole genome microarray expression profiling as a discovery platform to iedntify the gene expression induced by Atoh1 in colon cancer cells. Mutated Atoh1 (5SA-Atoh1) replaced 5 serine residues to Alanin for the protein stabilization were expressed in human colon cancer cellline; DLD1 cells. Triplicated RNAs were generated from GFP expressing DLD1 cells and 5SA-Atoh1 expressing DLD1 cell, respectively.
Project description:To investigate the function of ZNF692 in colorectal cancer, we established DLD1 cell lines in which target gene has been knocked out by CRISPR-cas. We then performed gene expression profiling analysis using data obtained from DLD1 colorectal human cells wt (sgC for guide control) or crispr knockout for ZNF692 (sgZ1 for guide 1, and sgZ3 for guide 3). We have each condition in triplicates.
Project description:To validate the suitability of two commonly used colorectal cancer cell lines, DLD1 and SW480, as model systems to study colorectal carcinogenesis, we treated these cell lines with β-catenin siRNA and identified β-catenin target genes using DNA microarrays. The list of identified target genes was compared to previously published β-catenin target genes found in the PubMed and the GEO databases. Based on the large number of β-catenin target genes found to be similarly regulated in DLD1, SW480 and LS174T as well as the large overlap with confirmed β-catenin target genes, we conclude that DLD1 and SW480 colon carcinoma cell lines are suitable model systems to study β-catenin regulated genes and signaling pathways
Project description:To explore the function of TTC7B on colon cancer，we established HCT116 TTC7B-KO/OE cell lines. The purpose of this study is to utilize next-generation sequencing techniques to investigate the effects of TTC7B knockout or overexpression on the biological behavior of tumor cells.
