Expression analysis of HepG2, HepG2-slug and HepG2-slug on Matrigel

ABSTRACT: Investigation of whole genome gene expression level changes in hepatocellular carcinoma cell line hepG2 in regular culture, hepG2-slug in regular culture and hepG2-slug on Matrigel. Whole genome gene expression level changes have been compared in hepatocellular carcinoma cell line hepG2 in regular culture, hepG2-slug in regular culture and hepG2-slug on Matrigel. Roche NimbleGen micro-array analysis was employed to assess global genome expression in HepG2 in regular culture, HepG2-slug in regular culture and HepG2-slug on Matrigel. The results demonstrated that the up-regulated genes and the down-regulated genes increased significantly when HepG2-slug cells with VM forming ablity were cultured on Matrigel and formed VM.

Chip-chip from HepG2 cells and HepG2 cells with slug overexpression

Project description:The transcription factor slug represses genes with E-box and then activates cancer stem cell related pathway: Wnt, Notch and Hedgehog pathway. Chromatin immunoprecipitation (ChIP) of slug by ChIP-on-chip analysis demonstrated that slug indirectly activates cancer stem cell related pathway and thus promotes vasculogenic mimicry formation. Comparison of HepG2-control in regular culture, HepG2-slug in regular culture and HepG2-slug on Matrigel.

Influence of Slug/SNAI2 on global gene expression in CRC cells and tumors

Project description:To establish the role of Slug in CRC, we created a genetic CRC model for Slug expression. As parental cells, we selected HT-29 cells that display a pronounced epithelial phe-notype. HT-29 cells were transfected with Slug, and two stable Slug-expressing clones. (Slug1, Slug2) were isolated. As transfection control, we used HT-29 cells transfected with empty vector (control). To characterize the influence of Slug on gene ex-pression, transcriptome analysis was performed for the four HT-29 cell lines as well as for the corresponding tumor xenografts. Global expression profiling showed that Slug-overexpressing cells and tumors were clustered together while the parental and control cells and tumors formed a separate cluster. Next, a two-step analysis was carried out. First, a subtractive analysis was carried out comparing the gene profiles of Slug-expressing cells and tumors with the corresponding parental/control samples. Genes were considered to be significantly upregulated by Slug if the fold change (FC) was greater than +2 and downregulated if the fold change was less than −2 with p-values (false dis-covery rates) less than 0.01

The invasion promoter Slug is a critical cell cycle regulator

Project description:Background: The well-characterized function of the transcriptional repressor, Slug, is to promote EMT and tumor invasion/metastasis by down-regulating E-cadherin expression. In this study, we investigated the significance of Slug during the S phase. Method: Slug mRNA expression was isolated from thymidine-arrested CL1-5/AS2neo (control) and CL1-5/AS2neo-Slug-WT stable cells. The Agilent oligonucleotide microarray analysis was performed to identify Slug downstream genes. Results: Overexpression of Slug inhibited lung [3H]-thymidine incorporation and delayed S phase progression. By using Agilent microarray we have identified panel of genes altered by Slug overexpression. Slug can down-regulate target genes about cell cycle networks for DNA replication, DNA replication checkpoint and genomic stability, such as TOP1, ORC4, RFC3, and Rad17. Conclusions: the multifaceted role of Slug in cancer progression by controlling the epithelial-mesenchymal transition and genome stability. Two-condition experiment, Vector vs. Slug overexpression cells. The cDNAs encoding full-length human Slug were amplified and subcloned into lentiviral pLKO_AS2.neo which generated full-length Slug. Vector control or Slug lentivirus were transduced into CL1-5 cells and Gentamycin was used to select stable cells.

The transcription factors Snail and Slug activate the TGF-B signaling pathway in breast cancer

Project description:Gene expression profiling to determine transcriptome changes following Snail or Slug expression in MCF-7 breast cancer cells Samples were isolated in three biological replicates for microarray analysis. Four MCF-7 breast cancer cell subsets: MCF-7(untreated), MCF-7 (with Control adenovirus), MCF-7 (with Snail adenovirus) and MCF-7 (with Slug adenovirus). RNA was purified on Day 0 for untreated, and on days 1,2 and 4 for the remaining three subsets for gene expression profiling on microarray.
