Kinetic analysis of TGFbeta-induced EMT in NMuMG/E9 cells

ABSTRACT: To investigate the transcriptional remodelling during EMT, we treated normal murine mammary gland epithelial cells with TGFbeta for 0, 2h, 6h, 12h, 24h, 36h, 48h, 60h, 72h, 96h, 168h and 240h. Using WGCNA and pathway enrichment analysis we identified multiple gene expression modules that were enriched in general, signaling, metabolic or stuctural pathways highly relevant for EMT.

Mesenchymal Epithelial Transition (MET) Timecourse of NMuMG-E9 cells treated with TGFb

Project description:Background: Epithelial-mesenchymal transition (EMT) has been implicated in metastasis, drug resistance, survival under stress and also conferring stem cell-like traits to cancer cells. However, several of the studies have been carried out using model systems that don’t appropriately recapitulate all stages of the dynamic process of EMT. Hence, there is a need to overcome this limitation by development of a model system that allows us to mimic each stage of EMT and accurately assess the plastic changes associated with it. Methods: We have derived a cancer cell line from the PyMT-MMTV model of breast cancer, named PyMT-1099 cells, and undertaken a detailed characterization of the morpho-genetic changes it undergoes during a TGFbeta-induced EMT. Further, we have also performed high throughput transcriptomics on PyMT-1099 cells undergoing EMT in a high resolution kinetic of TGFbeta treatment. Results: We show that PyMT-1099 cells undergo an EMT comparable to the classically used immortalized NMuMG cells as assessed by morphological, and marker expression changes on TGFbeta treatment. Further, PyMT-1099 cells can also migrate in vitro in response to TGFbeta treatment. These cells are also tumorigenic and lead to metastasis formation when transplanted into immunocompromised mice. Conclusion: In this study we report the development of PyMT-1099 cells as an excellent tool to model and study breast cancer-associated EMT both in vitro and in vivo and show that these cells overcome the limitations posed by other cellular systems currently being used to study EMT

Gene expression from NMuMG cells overexpressing major satellite treated with TGFbeta

Project description:Although heterochromatin is enriched with repressive traits, it is also actively transcribed, giving rise to large amounts of non-coding RNAs. Although these RNAs are responsible for the formation and maintenance of heterochromatin, little is known about how their transcription is regulated. Here we show that the Snail1 transcription factor represses pericentromeric transcription, acting through the H3K4 deaminase LOXL2. Since Snail1 plays a key role in the epithelial to mesenchymal transition (EMT), we analyzed the regulation of mouse heterochromatin transcription in this process. At the onset of EMT, one of the major structural heterochromatin proteins, HP1a, is transiently released from heterochromatin foci in a Snail1/LOXL2–dependent manner during EMT, concomitantly with a down-regulation of major satellite transcription. Global transcriptome analysis indicated that ectopic expression of heterochromatin transcripts affects the transcription profile of EMT-related genes. Additionally, preventing the down-regulation of major satellite transcripts compromised the migratory and invasive behavior of mesenchymal cells. We propose that Snail1 regulates heterochromatin transcription through the histone-modifying enzyme, LOXL2, thus creating the favorable transcriptional state necessary for completing EMT. Keywords: Expression Profiling by array We analyzed 2 arrays from each condition: Control and Major treated 8 hours with TGFbeta

Histone modification analysis in TGFbeta/TNFalpha treated A549 spheroid cultures

Project description:We studied the extent of chromatin remodeling in an in-vitro model of the epithelial-mesenchymal transition (EMT). EMT is induced in spheroid cultures (3D) using simultaneously two cytokines: TGFbeta and TNFalpha.

A systematic analysis of the time series gene expression in TGF-beta induced EMT by Next-generation sequencing

Project description:The goal of this study is to characterize time course gene expression profiles during TGF-beta induced EMT. In particular, we aim to identify and characterize master transcription factors regulate the transition into partial-EMT state. A time series mRNA profile in A549 cells is generated from TGF-beta induced EMT samples during 0h,6h,12h,24h,36h,48h,72h and 96h by deep sequencing, in duplicate, using Illumina HiSeq 2500

Gene expression analysis in TGFbeta/TNFalpha treated A549 spheroid cultures

Project description:TGFbeta/TNFalpha treated spheroid A549 cultures are a model of the epithelial-mesenchymal transition (EMT). These experiments capture the changes in global gene expression that result from cells being induced to undergo EMT (3D control vs 3D treated), but also the differences in gene expression when A549 is grown in spheroid cultures (2D control vs 3D untreated). EMT is efficiently induced only in the spheroid culture model.

Genomic survey of NPF and NRT2 transporter gene families in five inbred maize lines and their responses to pathogens infection

Project description:To further confirm whether the expression of NRT genes were influenced by pathogen infection, maize leaves were sampled at 0h, 24h, 40h, 60h and 96h post inoculation with wild-type strain Colletotrichum graminicola, the causing agent of maize anthracnose disease.

Single cell RNA-seq and ATAC-seq of EMT induced by TGFbeta stimulation and Zeb1 overexpression

Project description:We report the application of single cell RNA-sequencing using indrop on an HMLE breast cancer cell line that we induced to undergo EMT. We measured 7523 single cells after 8 and 10 days of stimulation with TGFbeta. In addition, we measured 3496 single cells in an engineered HMLE cell line with Dox inducible Zeb1, after 2 days of stimulation with Doxycycline. Finally, we performed ATAC-seq on CD44 sorted HMLE cells after 8 days of stimulation with TGFbeta.
