Cellular and extracellular vesicle RNA sequence for E-cadherin-RFP EMT reporter system expressing mouse breast cancer cell line Py2T during EMT/MET

ABSTRACT: Epithelial-mesenchymal transition (EMT) is a process by which epithelial cells lose cell-cell contact and gain cancer malignancy such as invasion, stemness, chemoresistance and metastasis. Reverse precess, mesenchymal-epithelial transition (MET) is also important for colonization. Extracellular vesicles (EVs) secreted from cancer cells are also important for cancer malignancy. To analyze RNAs from cells and EVs during EMT and MET, RNA sequencing was performed using E-cadherin-RFP/Py2T reporter system.

Transforming growth factor β (TGFβ) induces epithelial-mesenchymal transition (EMT), which correlates with stemness and invasiveness. Mesenchymal-epithelial transition (MET) is induced by TGFβ withdrawal and correlates with metastatic colonization. Whether TGFβ promotes stemness and invasiveness simultaneously via EMT remains unclear. We established a breast cancer cell model expressing red fluorescent protein (RFP) under the E-cadherin promoter. In 2D cultures, TGFβ induced EMT, generating RFP< ...[more]

Regan2022 - Mechanosensitive EMT model

Project description:This file contains a 136-node modular Boolean network model of EMT triggered by biomechanical and growth signaling crosstalk, linked to a published network of epithelial contact inhibition, proliferation, and apoptosis (MODEL2006170001). This model reproduces the ability of the core EMT transcriptional network to maintain distinct epithelial, hybrid E/M and mesenchymal states, as well as EMT driven by mitogens such as EGF on stiff ECM. We also reproduce the observed lack of stepwise MET, in that our model's dynamics does not pass through the hybrid E/M state during MET. We show that in the absence of strong autocrine signals such as TGFβ (not included in this version), cells cannot maintain their mesenchymal state in the absence of mitogens, on softer matrices, or at high cell density.

Regan2022 - Mechanosensitive EMT model with autocrine TGFbeta signaling

Project description:This model is an expansion of the Regan2022 - Mechanosensitive EMT model (MODEL2208050001); it includes a TGFβ signaling module and autocrine signaling in mesenchymal cells. The expanded 150-node (630 link) modular model undergoes EMT triggered by biomechanical and growth signaling crosstalk, or by TGFβ. As its predecessor, this model also reproduces the ability of the core EMT transcriptional network to maintain distinct epithelial, hybrid E/M and mesenchymal states, as well as EMT driven by mitogens such as EGF on stiff ECM. We also reproduce the observed lack of stepwise MET, in that our model's dynamics does not pass through the hybrid E/M state during MET. We show that in the absence of strong autocrine signals such as TGFβ (not included in this version), cells cannot maintain their mesenchymal state in the absence of mitogens, on softer matrices, or at high cell density. In contrast, potent autocrine signaling can stabilize the mesenchymal state in all but very dense monolayers on soft ECM. This expanded model also reproduces the inhibitory effects of TGFβ on proliferation and anoikis resistance in mesenchymal cells, as well as its ability to trigger apoptosis on soft ECM vs. EMT on stiff matrices. The model offers several experimentally testable predictions related to the effect of neighbors on partial vs. full EMT, the tug of war between mitosis and the maintenance of migratory hybrid E/M states, as well as cell cycle defects in dynamic, heterogeneous populations of epithelial, hybrid E/M and mesenchymal cells.

Gene Transcriptional Variation of Hepatic Progenitor Cells after TGF- 1-Induced EMT Transition and EGF-Induced MET Reversion

Project description:TGF-b1 induces hepatic progenitor cells experience an epithelial-mesenchymal transition, and EGF could reverse this process via mesenchymal-epithelial transition. Yet, the mechanism underline these EMT and MET processes are not clear. The aim of this study is to reveal the genes with significant difference during these EMT and MET process in hepatic progenitor cells.

Single-cell resolution of MET- and EMT-like programs in osteoblasts during zebrafish fin regeneration

Project description:We performed single-cell RNA-sequencing (scRNA-seq) to elucidate osteoblastic transcriptional programs during zebrafish caudal fin regeneration. We show that osteoprogenitors are enriched with components associated with epithelial-to-mesenchymal transition (EMT) and its reverse, mesenchymal-to-epithelial transition (MET). Trajectory analyses indicate osteoblastic cells solely expressed EMT components, or transiently expressed components for MET before EMT. We provide evidence that the EMT markers cdh11 and twist2 are co-expressed in dedifferentiating cells at the amputation stump, and in differentiating osteoblastic cells in the regenerate, the latter of which are enriched in EMT signatures. We also show that esrp1, a regulator of alternative splicing in epithelial cells that is associated with MET, is expressed in a subset of osteoprogenitors during outgrowth. This study provides a single cell resource for the study of osteoblastic cells during zebrafish fin regeneration, and supports the contribution of MET- and EMT-associated components to this process.

Tead2 expression levels control the subcellular distribution of Yap and Taz, zyxin expression and epithelial-mesenchymal transition (ChIP-seq)

Project description:Cellular changes during an epithelial-mesenchymal transition (EMT) largely rely on global changes in gene expression orchestrated by transcription factors. Tead transcription factors and their co-factors Yap and Taz have been shown to be implicated in EMT, nevertheless, their direct target genes during EMT have remained elusive.We used genome-wide chromatin immunoprecipitation and next generation sequencing to identify diect Tead2 target genes during EMT. Py2T cells (murine breast cancer cell line) were treated with TGFβ for 5 days and subjected to ChIP using an antibody for Tead2 followed by next generation sequencing (Illumina HiSeq 2000; n=2)

Gene expression in epithelial, EMT (epithelial-mesenchymal transition) and MET (mesenchymal-epithelial transition) cells

Project description:NMuMG is an epithelial cell line that can be induced into EMT by TGF-β treatment or MET by TGF-β withdrawl. During EMT, several marker genes were downregulated/upregulated, which is consistent with its mesenchymal phenotype. Transcription factors that are regulated during EMT and its reverse process MET are candidate genes for the regulations of the EMT marker genes. NMuMG cells treated with vehicle, TGF-β for 11 days, or 11days of TGF-β treatment followed by TGF-β withdrawl for another 13 days. RNA from these 3 conditions of NMuMG were extracted and subject to microarray analysis

Identification of stable markers of the EMT:MET process

Project description:Epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET) facilitate breast cancer (BC) metastasis, however stable molecular changes that result as a consequence of these processes remain poorly defined. Therefore, we sought to identify molecular markers that could distinguish tumor cells that had completed the EMT:MET cycle in the hopes of identifying and targeting unique aspects of metastatic tumor outgrowth.Therefore, normal murine mammary gland (NMumG) cells transformed by overexpression of EGFR (NME) cells were cultured in the presence of TGF-beta1 (5 ng/ml) for 4 weeks, at which point TGF-beta1 supplementation was discontinued and the cells were allowed to recover for an additional 4 weeks (Post-TGF-Rec). Total RNA was prepared from unstimulated cells (Pre-TGF) of similar passage and compared by microarray analysis. The two groups were analyzed in triplicate, three Pre-TGF samples and three Post-TGF-Rec samples.

Tead2 expression levels control the subcellular distribution of Yap and Taz, zyxin expression and epithelial-mesenchymal transition (expression)

Project description:Cellular changes during an epithelial-mesenchymal transition (EMT) largely rely on global changes in gene expression orchestrated by transcription factors. Tead transcription factors and their co-factors Yap and Taz have been shown to be implicated in EMT, nevertheless, their direct and indirect target genes during EMT have remained elusive. We used microarrays to detail the changes in global programme of gene expression during TGFβ-induced EMT in a murine breast cancer cell line (Py2T). We compared expression profiles of treated Py2T breast cancer cell lines (5 days of TGFβ treatment 2ng/ml) to profiles of untreated cells, we used 2 biological replicates for each condition.
