Transcription profiling of glioblastoma primary culture treated with TGF-beta receptor inhibition.

ABSTRACT: TGF-beta has an oncogenic response in glioblastoma and it is considered to be a therapeutic target. We evaluated the effect of TGF-beta inhibition in glioblastoma. Differential gene expression analysis of patient-derived primary cultured glioblastoma cells treated with the TGF-beta receptor inhibitor, LY2109761 11 patient-derived cell cultures from 11 patients were treated with 2microM of the TGF-beta receptor inhibitor, LY2109761, for 3 hours or left untreated and RNA was isolated and microarray analysis was performed

Glioma-initiating cells (GICs), also called glioma stem cells, are responsible for tumor initiation, relapse, and therapeutic resistance. Here, we show that TGF-β inhibitors, currently under clinical development, target the GIC compartment in human glioblastoma (GBM) patients. Using patient-derived specimens, we have determined the gene responses to TGF-β inhibition, which include inhibitors of DNA-binding protein (Id)-1 and -3 transcription factors. We have identified a cell population enriched ...[more]

Transcription profiling of human glioma cells treated with TGF-beta or an inhibitor of the TGF-beta Receptor I LY2109761

Project description:In order to identify the genes that are regulated by TGF-beta in glioma, we serum starved two glioma cell lines, U373MG and U87MG, for 16h and we treated them with vehicle,100pM TGF-beta, 2uM inhibitor of the TGF-beta Receptor I(TbRI)(LY2109761), or both 100pM TGF-beta plus 2uM TbRI for 3h. Then, cell were collected and total RNA was extracted.

Integration of TGF-β-induced Smad signaling in the insulin-induced transcriptional response in endothelial cells

Project description:The goal of the current study was to examine the extent to which TGF-beta signaling contributes to insulin-induced transcriptional responses in endothelial cells (HUVECs). HUVECs cells were treated with or without insulin in the absence or presence of SB431542, a TGF-beta receptor kinase inhibitor. Cells were sequenced using Hiseq 2000 (Illumina) as paired-end 2x100 base reads.

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

Project description: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.

TGF-beta-activated cancer-associated fibroblasts limit cetuximab efficacy in preclinical models of head and neck cancer

Project description:Most head and neck cancer (HNC) patients are resistant to cetuximab, an antibody against the epithelial growth factor receptor. Such therapy resistance is known to be mediated, in part, by stromal cells surrounding the tumor cells; however, the mechanisms underlying such a resistance phenotype remain unclear. To identify the mechanisms underlying cetuximab resistance in an unbiased manner, RNA-sequencing (RNA-seq) of HNC patient-derived xenografts (PDXs) was performed. Comparing the gene expression of HNC-PDXs before and after treatment with cetuximab indicated that the TGF-beta signaling pathway was upregulated in the stromal cells of PDXs that progressed to cetuximab (CetuximabProg-PDX). However, in PDXs that were extremely sensitive to cetuximab, and when tumors shrunk following cetuximab treatment (CetuximabSen-PDX), the TGF-beta pathway was downregulated in the stromal compartment. Histopathological analysis of PDXs showed that in CetuximabProg-PDX, TGF-beta-activation was detected in cancer-associated fibroblasts (CAFs). These TGF-beta-activated CAFs were sufficient to limit cetuximab efficacy in vitro and in vivo. Moreover, blocking the TGF-beta pathway using the SMAD3 inhibitor, SIS3, enhanced cetuximab efficacy and prevented the progression of CetuximabProg-PDX. Altogether, our findings indicate, for the first time, that TGF-beta-activated CAFs play a role in limiting cetuximab efficacy in HNC.

TGF-β uncouples glycolysis and inflammation in macrophages and controls the survival during sepsis

Project description:<p>The mechanisms by which macrophage metabolism is regulated and the effects of metabolism on diseases remain largely unknown. We show here that TGF-β regulates the glycolysis of macrophages independently of inflammatory cytokine production, and thus affects the survival in experimental sepsis. Specifically, TGF-β increased expression and activity of phosphofructokinase-1 liver type (PFKL) in macrophages and thus promoted their glycolysis during cell activation, yet paradoxically suppressed the production of proinflammatory cytokines in the same macrophages. The upregulation of glycolysis was mediated by a mTOR-c-MYC dependent pathway, whereas the inhibition of cytokines was ascribed to the activation of SMAD3 and a downregulated activation of the pro-inflammatory transcription factors AP-1, NFkB and STAT1. Importantly, in an LPS-induced endotoxemia and CLP-sepsis models, TGF-β enhancement of macrophage glycolysis led to a decreased survival in mice, which was associated with increased blood coagulation. Analysis of cohorts of patients with sepsis and covid-19 revealed that the expression of PFKL, TGF-β receptor TGFBRI and coagulation factor F13A1 in myeloid cells positively correlated with the progression of the disease. Thus, TGF-β is emerging as a critical cytokine regulating macrophage metabolism and could serve as a therapeutic target in patients with sepsis.</p>

Gene expression analysis of TGF-beta signaling-disrupting gastric cancer cell line 2MLN

Project description:Diffuse-type gastric carcinoma is a poor-prognostic cancer with high expression of transforming growth factor (TGF)-β and thick stromal fibrosis. However, detailed investigations on the roles of TGF-β signaling in diffuse-type gastric carcinoma have not been performed. We generated two diffuse-type gastric carcinoma cell lines, dominant-negative TGF-β type II receptor expressing cells (2MLN-dnTβRII) and GFP-expressing cells (2MLN-GFP). Cells were subcutaneously or orthotopically injected into nude mice. Although dnTβRII did not affect the growth of OCUM-2MLN in vitro, it accelerated the growth of subcutaneously or orthotopically transplanted tumors in vivo. By microarray analysis, we found gene expression of TSP-1, an angiogenic inhibitor, was down-regulated in dnTβRII tumors. This results suggested disruption of TGF-β signaling in diffuse-type gastric carcinoma cells leads to alteration of tumor microenvironment and acceleration of tumor growth. We generated two OCUM-2MLN-derived gastric carcinoma cell lines; 2MLN-dnTβRII, which expresses dominant negative form of TβRII, and control 2MLN-GFP, which expresses GFP. The transplanted tumors of these cell lines were subjected to gene expression analysis with Affymetrix U133 plus2 arrays.
