Identification of TGF-β regulated lncRNAs in GBM cells using microarray screen

ABSTRACT: To identify TGF-β regulated lncRNAs in glioblastoma, we performed a genome-wide microarray screen in T98G glioma cells. T98G cells were treated with 10 ng/ml TGF-β (24h) and differentially expressed lncRNAs were identified using microarray in comparison with control cells.

Identificaion of long noncoding RNAs related to TGF-β signaling in human cultured tubular epithelial cells

Project description:To identify differentially expressed long noncoding RNAs (lncRNAs) upon TGF-β stimulation in human cultured tubular epithelial cells HK2 and HKC8, we have employed long noncoding RNA microarray expression profiling as a discovery platform to find differentially expressed lncRNAs with TGF-β stimulation in these cells. Cultured human tubular epithelial cells HK2 and HKC8 were stimulated with PBS or TGF-β1. After incubation with TGF-β1 (10ng/ml) for 24 hours, 86 overlapping lncRNAs were upregulated and 47 overlapping lncRNAs were downregulated more than 2 fold vesus cells treated with PBS in these two epithelial cell lines. Expression of ENST00000429588 from this result was quantified in the same RNA samples by real-time PCR, confirming the upregulation upon TGF-β stimulation is repeatable.

Human Pancreatic Beta Cell lncRNAs Control Cell-Specific Regulatory Networks

Project description:Recent studies have uncovered thousands of long non-coding RNAs (lncRNAs) in human pancreatic β cells. β cell lncRNAs are often cell type specific and exhibit dynamic regulation during differentiation or upon changing glucose concentrations. Although these features hint at a role of lncRNAs in β cell gene regulation and diabetes, the function of β cell lncRNAs remains largely unknown. In this study, we investigated the function of β cell-specific lncRNAs and transcription factors using transcript knockdowns and co-expression network analysis. This revealed lncRNAs that function in concert with transcription factors to regulate β cell-specific transcriptional networks. We further demonstrate that the lncRNA PLUTO affects local 3D chromatin structure and transcription of PDX1, encoding a key β cell transcription factor, and that both PLUTO and PDX1 are downregulated in islets from donors with type 2 diabetes or impaired glucose tolerance. These results implicate lncRNAs in the regulation of β cell-specific transcription factor networks.

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.

TGF-b-activated LncRNA LINC00115 is a critical regulator for glioma stem-like cell tumorigenicity

Project description:Long non-coding RNAs (lncRNAs) are critical regulators in cancer. However, the involvement of lncRNAs in TGF-beta-regulated tumorigenicity is still unclear. Here we identify TGF-beta-activated lncRNA LINC00115 as a critical regulator in glioma stem-like cell (GSC) self-renewal and tumorigenicity. LINC00115 is upregulated by TGF-beta, acts as a miRNA sponge and upregulates ZEB1 by competitively binding miR-200s, thereby enhancing ZEB1 signaling and GSC self-renewal.

Long non-coding RNAs induced by TGF-beta in three breast (cancer) cell lines

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.

Long non-coding RNAs and mRNAs regulated by TGF-β

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 promotes the invasion-metastasis cascade, which 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.

Expression data of lncRNA from MCF7 cells treated or not treated with TGF-β

Project description:TGF-β is a major inducer of epithelial-mesenchymal transition (EMT) during cancer progression, mainly by activating a set of pleiotropic transcription factors and other classes of genes We used microarrays to detail the global programme of gene expression underlying TGF-β-induced EMT and identified distinct classes of TGF-β-regulated lncRNAs during this process.

Effect of human TGF-β on the gene expression profile of Echinococcus granulosus protoscoleces

Project description:TGF-β is a crucial cytokine participate in the interplay between the intermediate host and helminthes. TGF-β receptors were discovered in many cestode, and could bind the human TGF-β. However, the function of host TGF-β on the Echinococcus is still not elucidated, and this paper aim to explore the question at transcription level. Microarray analysis was used to investigate differential expression genes in protoscolices of Echinococcus granulosus cultured in the presence or absence of human TGF-β at different time points (4h, 8h and 24h) in vitro. A total of 523 genes were up- or down-regulated in response to TGF-β, compared with control group, 390 genes were up-regulated and 47 genes were down-regulated at 8h, and 376 genes were up-regulated and 19 genes were down-regulated at 12h, including 310 differential genes were regulated at both time point. Only 1 gene down-regulated at 4 h. Gene ontology (GO) analysis showed that the biological process of the up-regulated genes in protoscolex were predominantly involved in DNA packaging, nucleosome assembly, chromatin assembly, etc. And the cellular component gene were located in cell nucleus. TGF-β appeared to promote growth or development of the protoscolex by up-regulated the gene related with mitosis. In addition, the study also indicated that TGF-β has a multiple influence on the protoscolex, as reflected in the increased stimulation of gene expression of the ErbB signaling pathway, MAPK signaling pathway, Notch signaling pathway and VEGF signaling pathway.

Expression data from TGF-beta-treated human ovarian fibroblasts

Project description:Advanced ovarian cancer is the most lethal gynecologic malignancy in the United States. Ovarian cancer cells are known to have diminished response to TGF-beta, but it remains unclear whether TGF-beta can modulate ovarian cancer cell growth in an indirect manner through cancer-associated fibroblasts (CAFs). Using transcriptome profiling analyses on TGF-beta-treated ovarian fibroblasts, we identified a TGF-beta-responsive gene signature in ovarian fibroblasts. Identifying TGF-beta-regulated genes in the ovarian microenvironment helps in understanding the role of TGF-beta in ovarian cancer progression. The human telomerase-immortalized ovarian fibroblast line NOF151 was treated with 5ng/mL of either TGF-beta-1 or TGF-beta-2. Total RNA was isolated from control samples and TGF-beta-treated fibroblasts samples at 48 hours post-treatment, followed by cDNA synthesis, IVT and biotin labeling. Samples were then hybridized onto Affymetrix Human Genome U133 Plus 2.0 microarrays. For each treatment group, three independent samples were prepared for the microarray experiment.
