Expression analysis of colorectal cancer cell line SW480 expressing FOXC2
Ontology highlight
ABSTRACT: Investigation of whole genome gene expression level changes in a colorectal cancer cell line SW480 expressing FOXC2, compared to the pBabe control cells. Genes associated with metastasis regulated by FOXC2 in colorectal cancer were analysed. The role of FOXC2 in breast cancer metastasis are further described in Mani SA, Yang J et al. Mesenchyme Forkhead 1 (FOXC2) plays a key role in metastasis and is associated with aggressive basal-like breast cancers. PNAS 2007; 104: 10069-10074 . A six chip study using total RNA recovered from three separate cultures of SW480/pBabe and three separate cultures of SW480/FOXC2. Each chip measures the expression level of 45033 genes from SW480/pBabe or SW480/FOXC2.

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.
Project description:We used microarrays to investigate the transcription profile of FOXC2 expression in a human mammary epithelial cell line. HMLER cells were infected with either a control vector or a retroviral vector expressing FOXC2.
Project description:The transcription factor Snail is known as an EMT regulator to promote cancer metastasis. Identification Snail-regulated miRNAs helps to uncover mechanisms governing CRC metastasis The stable SW480-vector and Snail-expressing cells were established for miRNA microarray analysis.
Project description:The goal of this study was to determine genes affected by expressing KRAS mutation (G12V) in NCI-H1703 cells This data was used in Meng Wang et. al. Cancer Research 2016 to determine the alterations of gene expression profiling associated with expression of KRAS mutation (G12V). The experiment uses a pBABE-Puro vector encoding KRAS G12V and a corresponding empty vector control.
Project description:Gene expression profiling has been widely used to screen for metastasis-associated genes by comparing the difference in paired primary and metastatic colorectal carcinomas, orthotopic implantation mouse model or cells with different metastatic potential in the field of CRC research In our study, we observed that the genes differentially expressed in M5 relative to its parent SW480 cell line Here we used the SW480, a human CRC cell line, as a model system. In vivo variant lines with increasing metastatic capacity were selected in a metastatic orthotopic model of human CRC. A subpopulation named as M5 with enhanced metastatic abilities to liver was isolated by in vivo selection of SW480 cells. We identified genes associated with tumor metastasis by comparing the difference between high metastatic subclone and its parent cells.
Project description:Transcript profiling to identify genes where the mRNA expression levels are differentially regulated in white adipose tissue of transgenic mice overexpressing the FOXC2 gene compared with adipose tissue of wild-type mice.
Project description:Transcription profiling from young and pre-senescent IMR90 cells, transfected either with hTERT (pBabe-puro-hTERT) or vector control (pBabe-puro). Population doubling values are contained in Characteristics[generation] column.
Project description:To understand the growth inhibition of peptidylarginine deiminase 2 (PAD2) and small molecule 1B8, colon cancer SW480 cells were treated with compound 1B8 for 24 hours, SW480 cells were transfected with humanPAD2 vector for 24 hours. Cells were harvested and total RNA was extracted using TRIZol method followed by Agilent DNA microarray analysis. To profile the effected genes by compound 1B8, SW480 cells were treated with DMSO (control) and 10uM 1B8 in triplicates in 6-well plate, cells were harvested 24 hours later. To compare the effected genes by compound 1B8 and PAD2 overexpression, SW480 cells were transfected with PAD2 and pIRES2-EGFP empty vector in triplicates in 6 well plates, cells were harvested in 24 hours. All the cells were harvested and total RNA was extracted using TRIZol method followed by Agilent DNA microarray analysis.
Project description:Two colon cancer cell lines, SW480 and SW620, were originated from the same patient. The SW480 cell line was derived from a primary lesion, and the SW620 cell line was cultured from a lymph node metastasis with no intervening chemotherapy at a later time. Since these two cell lines are from a single person, it is likely that differences between the two cell lines represent the changes when cancer cells acquire metastatic potential. Thus, this system represents a perfect model for the study of metastatic mechanism. To investigate cancer metastasis associated miRNAs, we detected the miRNA profiles in these two cell lines.
