Project description:To investigate the cooperative function ALDH1B1 in the regulation of colon cancer cells, we established SW480 cell lines in which ALDH1B1 has been knocked down by shRNA and the control SCR SW480 cells.
Project description:Cancer stem-like cells are defined as small population of cancer cells which has, higher tumor-initiating ability, self-renewing ability and differentiation ability. In this experiment, transcription profile of cancer stem-like cells derived from human colon cancer line cell SW480 was investigated. Cancer stem-like cells were isolated as side population (SP) cells by Hoechst33342 dye staining from human colon cancer line cell SW480. Non-cancer stem-like cells were isolated as main population (MP) cells. RNAs were isolated from SP cells and MP cells derived from SW480 cells and array experiment was perfromed in dye swaped fashion.
Project description:To compare lncRNAs and mRNAs expression profiles in colon cancer after co-cultured with CB and without CB, we extracted total RNA of colon cancer cell line(SW480) after co-cultured with CB(SW480/CB) and paired control without CB(SW480/ctr), and identified the dysregulated lncRNAs and mRNAs using Agilent Human lncRNAs/mRNAs microarrays.
Project description:The WWOX gene is a tumor suppressor probably involved in regulation of cell cycle and apoptosis and downregulated in variety of cancer types.However, its role in colon cancerogenesis is unknown. The aim of this study was to characterize how WWOX may be involved in colon cancerogenesis or cancer progression, how it influences the basic cancer cell features and modifies cell expression profile.Our observations suggest that in HT29 colon cancer cell line increased expression of WWOX may result in transition of cancer cells into more normal- like colon epithelium phenotype, on the other hand in SW480 WWOX revealed the well-known tumour suppressor properties. However, as the colon cancer is very heterogeneous disease, obtained discrepancies may reflect the known differences between cell lines and cancerogenesis pathway, which they undergone. SW480 colon cancer cells were stably transfected with WWOX cDNA. SW480 cells transfected with an empty vector served as a control. Total mRNA was isolated to look for gene-expression differences induced by the WWOX overexpression.
Project description:Assess the full impact of estrogen receptor beta on transcription by a full transcriptome analysis of ERb-mediated gene regulation in the SW480 colon cancer cell line. The colon cancer cell line SW480 does not express endogenous ER but is made ERb-expressing by lentiviral transduction of an ERb expression cassette. Introduction of ERb makes it possible to study the role and function of ERb in colon cancer as well as the impact ERb has on its own (in the absence of ERa).
Project description:Transcriptional profiling of human colon cancer SW480 cells comparing control untreated SW480 cells with cells stably transfected with LRP16 treated with or without etoposide (50 μM) for the indicated periods (0,1hour, 3hours).An exploratory microarray analysis was performed with mRNA extracted from clutured SW480 cells transfected with LRP16 or control plasmid that were treated with or without etoposide. Total RNA of colon cancer cells stably transfected with vector control and LRP16 treated with or without etoposide (50 μM) for the indicated periods was isolated and purified using RNeasy Kit (Qiagen, Hilden, Germany). Integrity of RNA was assessed by using an Agilent BioAnalyser 2100 (Agilent Technologies).
Project description:STAT3 is determined to play a crucial role in JAK/STAT signaling pathway. The mutations and copy number alteration of STAT3 can cause cancers and other diseases. The 317-567 amino acid domain of STAT3 protein contributes to binding with genomic DNA for gene activation. However, the impact of the mutations within DNA binding domain of STAT3 on the genomic binding pattern is not fully understood. Stat3 was deleted the 400-411 amino acid residue of \\"NNGSLSAEFKHL\\" using CRISPR-CAS9 in human colon cancer cells SW480. The cells were performed STAT3 ChIP-seq to investigate the genome-wide binding pattern of STAT3 between wild type and mutant STAT3 of SW480.
Project description:Analysis of SW480 cells following knockdown of Ezrin using RNAi. Ezrin is a protein that regulate the organization of cytoskeleton. Ezrin KD SW480 was used to study the role of ezrin in colon cancer. Keywords: ezrin, colon cancer, migration
