RNA-seq of SW480 colorectal cancer cells transfected with siRNAs targeting different putative metastasis promoting genes

ABSTRACT: Here we analyze the transcriptional profiles of SW480 colorectal cancer cells transfected with siRNAs targeting 26 different candidate genes potentially promoting metastasis. UMAP analysis of the transcriptional profiles of these cells revealed clusters potentially indicating some genes to operate in related pathways.

Next Generation Sequencing Facilitates Quantitative Analysis of SW480 cells and HPSE-knockdown SW480 cells Transcriptomes

Project description:Heparanase (HPSE), the only known mammalian endoglycosidase responsible for heparan sulfate cleavage, is a multi-faceted protein affecting multiple malignant behaviors in cancer cells. The goals of this study are to compare the mRNA transcriptome differences between SW480 cells and HPSE-knockdown SW480 cells. Methods: mRNA profiles of SW480 cells and HPSE-knockdown SW480 cells were generated by deep sequencing, in triplicate, using Illumina.

Membrane enriched proteome of transfected SW480 cells

Project description:This project used membrane-enriched proteomics to compare the membrane proteome of SW480 human colorectal cancer subclones that had been transfected with the full length coding sequence of the beta-6 integrin subunit under an overexpression promoter (SW480OE) against SW480 cells that had been transfected with an ‘empty’ mock vector (SW480M). Cell lysate samples were enriched for membrane proteins using a modified sodium carbonate stripping method before undergoing peptide immobilised pH gradient isoelectric focusing (IPG-IEF). Two IPG-IEF pH ranges were used to increase proteomic coverage: pH3-10 (broad range; BR) and pH3.5-4.5 (narrow range; NR). Each IPG-IEF strip was cut into 24 equal fractions and the peptides eluted. IPG-IEF of each pH range for both cell lines was performed in triplicate, resulting in four triplicate sets of 24 fractions. Data processing and bioinformatics: Spectra were identified against the *Homo sapiens* protein database (derived from Ensembl, Swiss-Prot and NCBI) using X!Tandem and the Global Proteome Machine (GPM) Tornado XE (build date 2010.12.01). GPM searches were set to tryptic peptides under GPM’s default fragment ion mass tolerance of 0.4Da and did not include semi-cleavage. Searches included single acid polymorphisms and default GPM residue modifications (oxidation,dioxidation, carbamidomethyl, deamidation, acetylation).

RNA-seq of ITPR3 knockout in SW480 colorectal cancer metastases

Project description:Here we analyze the transcriptional profiles of liver metastases formed by sgCtrl versus sgITPR3 SW480 colorectal cancer cells. We find downregulated genes in sgITPR3 SW480 metastases to be enriched for pathways related to immune response and non-canonical NFkB signaling.

Human colon cancer SW480 cells: stably transfected with vector control and LRP16 treated with or without etoposide

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).

Human SW480 cells: Untreated vs H2O2 Treated

Project description:ChIP-on-chip tilling array comparing untreated human SW480 cells vs SW480 cells treated with 2mM H2O2 for 30min. Exposing cells to the reactive oxygen species, hydrogen peroxide, recruits DNA methyltransferase 1 (DNMT1) to damaged chromatin. DNMT1 becomes part of a complex(es) containing DNMT3B and members of Polycomb Repressive Complex 4. The goal was to determine the effect of hydrogen peroxide treatment on chromatin, including changes in histone modifications and binding patterns of chromatin-associated proteins. [Agilent-014706]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and EZH2. [Agilent-014707]: Two-condition: untreated SW480 cells (U) vs H2O2 treated SW480 cells (T). Five-mark: SIRT1, gamma-HA2X, DNMT1, DNMT3B, and EZH2.

MicroRNA expression profile between human colorectal cancer SW480 and SW620 cell line

Project description:Two isogenic human colorectal cancer cell lines (primary SW480 cell line and its lymph node metastatic variant SW620 cell line),as an in vitro metastatic model. We have demonstrated that SW620 cell line possesses high metastasis potential and SW480 cell linepossesses low metastatic potential. We want to compare the whole cell microRNAs profiles of two isogenic colorectal cancer cell lines (SW480 and SW620 cell line), to gain an insight into the molecular events of colon cancer metastasis.
