TGF-β and RREB1 coordinate EMT programs in NMuMG cells

ABSTRACT: 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.

TGF-β and RREB1 coordinate EMT programs in development and cancer

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 in pancreatic pre-malignant epithelial cells, lung adenocarcinoma cells, and embryonic stem cells. Moreover, SMADs and RREB1 also drive EMT-associated fibrogenic programs in epithelial cells and mesendoderm differentiation in pluripotent embryonic cells. These findings illuminate the orchestration of EMT associated programs in gastrulation, fibrosis, and cancer.

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.

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.

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.

Long noncoding RNA ELIT-1 acts as a Smad3 cofactor to facilitate TGF-β/Smad signaling and promote epithelial-mesenchymal transition

Project description:TGF-β is involved in various biological processes, including development, differentiation, growth regulation, and epithelial-mesenchymal transition (EMT). In TGF-β/Smad signaling, receptor-activated Smad complexes activate or repress their target gene promoters. Smad cofactors are a group of Smad-binding proteins that promote recruitment of Smad complexes to these promoters. Long noncoding RNAs (lncRNAs), that behave as Smad cofactors have thus far not been identified. Here, we characterize a novel lncRNA EMT-associated lncRNA induced by TGF-β-1(ELIT-1). ELIT-1 was induced by TGF-β-stimulation via the TGF-β/Smad pathway in TGF-β-responsive cell lines. ELIT-1-depletion abrogated TGF-β-mediated EMT progression and expression of TGF-β target genes including Snail, a transcription factor critical for EMT. A positive correlation between high expression of ELIT-1 and poor prognosis in lung adenocarcinoma and gastric cancer patients suggests that ELIT-1 may be useful as a prognostic and therapeutic target. RIP assays revealed that ELIT-1 bound to Smad3, but not Smad2. In conjunction with Smad3, ELIT-1 enhanced Smad-responsive promoter activities by recruiting Smad3 to the promoters of its target genes including Snail, other TGF-β-target genes, and ELIT-1 itself. Collectively, these data show that ELIT-1 is a novel trans-acting lncRNA that forms a positive feedback loop to enhance TGF-β/Smad3 signaling and promote EMT progression.
