Expression data from normal murine mammary epithelial cell line NMuMG stimulated with TGF-beta

Project description:TGF-beta is one of the most important cytokines that induce epithelial to mesenchymal transition (EMT). In this dataset, we examined TGF-beta induced changes in gene and exon level expression. Core probesets of two samples were analyzed. NMuMG cells were stimulated with TGF-beta for 24 h or left untreated.

TGF-β and RREB1 coordinate EMT programs in NMuMG cells

Project description:Epithelial-to-mesenchymal transitions (EMT) play prominent roles during development, regeneration and tumor progression. EMTs are triggered by TGF-β, RAS and other signals that cooperatively induce the expression of master EMT transcription factors such as SNAIL. Here, we elucidate how the TGF-β and RAS pathways jointly trigger EMTs and tie them to broader developmental programs. We identify RAS response element binding protein 1 (RREB1) as a critical partner of TGF-β-activated SMAD transcription factors in driving SNAIL expression and EMT program in mammary gland epithelial cells.

NMuMG cell response to TGF-beta and TGF-beta +2APB treatments

Project description:Recent studies demonstrate that Ca2+ signaling has an important role in EMT. Use of Ca2+ blockers such as 2APB can inhibit cell migration induced by TGF-β. Interestingly, we see an unexpected increase in Snail expression upon Ca2+ blocker treatment of both MCF10A and NMuMG cells; this increase is not observed with 2APB treatment alone. Therefore, we believe that 2APB plays a synergistic role with TGF-β in Snail induction. We propose to investigate the gene networks that change following 2APB +TGF-β treatment.

RNA-sequencing analysis of mouse epithelial NMuMG cells with Cas9 or UGCG knock out

Project description:We report the gene expression in mouse NMuMG cells with or without UGCG depletion using RNA sequencing. After data analysis, the 11218 transcripts were identified. Among these transcripts, the TGF-β signaling target genes and EMT marker genes were significantly upregulated in UGCG depleted NMuMG cells. Then we used these genes and mouse TGF-β or EMT gene signatures to do the gene set enrichment analysis and showed the negative correlation of UGCG and TGF-β signaling or EMT in NMuMG cells.

FAIRE-seq analysis of Ras transformed mouse mammary gland epithelial cells transfected with Etv4 and Etv5 siRNAs and stimulated with TGF-beta.

Project description:We performed global mapping of accessible chromatin in mouse mammary gland epithelial EpH4 cell line and its Ras-transformed derivative (EpRas) using formaldehyde-assisted isolation of regulatory element (FAIRE)-sequencing (seq) to analyze the mechanisms of transcriptional regulation during TGF-beta-induced EMT.

CRISPR-Cas9-mediated ALMS1 knockout inhibits TGF-β signalling and epithelial-mesenchyme transition.

Project description:In this project we evaluated the proteomic profiling with TGF-β stimuli at 24h in a CRISPR-Cas9 model for ALMS1 gene in HeLa cells. Proteomic results showed a majority inhibition of downstream regulated pathways by the TGF-β, associating the protein coding genes (PCG) with processes like focal adhesion or cell-substrate adherens junction. Finally, EMT biomarkers like VIM, DSP, EDIL3 and SNAI1 had the opposite pattern to what would be expected when activating the EMT. In conclusion, seems that the depletion of ALMS1 could be inhibiting the signals transduction through the TGF -β and the routes regulated downstream by it such as the EMT.

Untargeted Metabolomics analysis of A549 treated with 0.5 mM extracellular ATP and 10 ng/ml TGF-beta

Project description:Control, 0.5 mM extracellular ATP and 10 ng/ml TGF-beta were used to treated 5 million A549 lung cancer cells in vitro for 2, 6 and 12 hours. The untargeted metabolomics analysis was performed on the cell lysates. The main objective of the study was to determine changes in metabolite abundances in lung cancer after treatment with extracellular ATP and TGF-beta (a known EMT inducer).

Expression data from TGF-beta treated Panc-1 pancreatic adenocarcinoma cell line

Project description:TGF-beta treatment of Panc-1 pancreatic adenocarcinoma cell line on Affymetrix HG_U133_plus_2 arrays; triplicate experiments. The goal of the experiment is to profile temporal gene expression changes during TGF-beta-induced epithelial-mesenchymal transition (EMT). During EMT cancer cells lose their epithelial specifc proteins and gain mesenchymal proteins to acquire migratory and invasive phenotype essential for metastasis. Human Panc-1 pancreatic adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 48 h to induce EMT. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques.
