Project description:Long non-coding RNAs (lncRNAs) are emerging as pivotal modulators of signaling trnasduction, and thereby regulate multiple pathological processes including cancer. TGF-beta signaling contributes to cancer metastasis by inducing epithelial-to-mesenchymal transition (EMT). To screen lncRNAs that are induced by TGF-beta, MCF10A-M1, MCF10A-M2 and MDA-MB-231 cells were stimulated with TGF-beta (5 ng/mL) fo 0 h, 2 h, 8 h and 24 h. RNA was extracted from those cells and analyzed by RNA-seq.

Project description:To identify the cytokines secreted by mesenchymal-like cancer cells that activate macrophages, the cytokine profiles of conditioned media from MCF7, MCF7 induced to undergo EMT by treatment of TGF-β, TNF-α and prolonged mammosphere culture, and MDA-MB-231 cells were analyzed by RayBio® Human Cytokine Antibody Array V. 5 samples. There are 5 groups: MCF7, MCF7 induced to undergo EMT by treatment of TGF-β (TGF-β-MCF7), TNF-α (TNF-α-MCF7), prolonged mammosphere culture (MCF7M), and MDA-MB-231 cells

Project description:Epithelial-to-mesenchymal transitions (EMTs) and extracellular matrix (ECM) remodeling are distinct yet important processes during carcinoma invasion and metastasis. TGF-β and RAS, signaling through SMAD and RAS-responsive element-binding protein 1 (RREB1), jointly trigger expression of EMT and fibrogenic factors as two discrete arms of a common transcriptional response in carcinoma cells. Here we demonstrate that both arms form a program for lung adenocarcinoma pulmonary metastasis and identify chromatin determinants tying the expression of the constituent genes to TGF-β and RAS dual inputs. RREB1 binds near H4K16ac histone marks and histone H2A.Z-loaded nucleosomes at enhancers in the fibrogenic genes IL11, PDGFB, and HAS2 and the EMT transcription factor SNAI1, priming these enhancers for activation by a SMAD4-INO80 nucleosome remodeling complex in response to TGF-β. These regulatory properties set the fibrogenic EMT program apart from RAS-independent TGF-β gene responses and illuminate the operation and vulnerabilities of a transcriptional program that promotes metastatic outgrowth.

Project description:The role of TGF-β-induced epithelial-mesenchymal transition (EMT) in cancer cell dissemination is well established, but the involvement of lncRNAs in TGF-β signaling is still unknown. In this study, we observed that the lncRNA-Activated by TGF-β (lncRNA-ATB) was upregulated in hepatocellular carcinoma (HCC) metastases and associated with poor prognosis. lncRNA-ATB upregulated ZEB1 and ZEB2 by competitively binding the miR-200 family and then induced EMT and invasion. In addition, lncRNA-ATB promoted organ colonization of disseminated tumor cells by binding IL11 mRNA, inducing autocrine of IL11 and triggering STAT3 signaling. Globally, lncRNA-ATB promotes the invasion-metastasis cascade. Thus, these findings suggest that lncRNA-ATB, a mediator of TGF-β signaling, could predispose HCC patients to metastases and may serve as a potential target for anti-metastatic therapies. To identify mRNA species bound by lncRNA-ATB, we performed an RIP to pull down endogenous mRNAs associated with the lncRNA-ATB and sequenced the retrieved RNA.
