Gene expression of human bone marrow mesenchymal stem cell (hBMSCs) during osteogenesis with or without TNF-alpha

Project description:In our previous study, we found that TNF-alpha (100ng/mL) different treatment times have opposing effects on BMSC osteogenesis. To investigate the roles of TNF-alpha in the osteogenic differentiation of hBMSCs, we performed gene microarray to detected the gene expression of hBMSCs with or without TNF-alpha during osteogenesis on days 3 and 4.

TNF-α-induced endothelial differentiation of human mesenchymal stem cells

Project description:Mesenchymal stem cells (MSCs) can differentiate into endothelial cells; however, the mechanisms underlying this process in the tumor microenvironment (TME) remain elusive. This study shows that tumor necrosis factor alpha (TNF-α), a key cytokine present in the TME, promotes the endothelial differentiation of MSCs by inducing vascular endothelial growth factor receptor 2 (VEGFR2) gene expression. EGR1 is a member of the zinc-finger transcription factor family induced by TNF-α. Our findings indicate that EGR1 directly binds to the VEGFR2 promoter and transactivates VEGFR2 expression. We also demonstrate that EGR1 forms a complex with c-JUN activated by c-JUN N-terminal kinase (JNK) to promote VEGFR2 transcription and endothelial differentiation in MSCs in response to TNF-α stimulation. The shRNA-mediated silencing of EGR1 or c-JUN abrogates TNF-α-induced VEGFR2 transcription and the endothelial differentiation of MSCs. Collectively, these findings demonstrate that the JNK-EGR1 signaling axis plays a crucial role in the TNF-α-induced endothelial differentiation of MSCs in the TME, which could be a potential therapeutic target for solid tumors vasculatures.

The effects of terbutaline or GW9508 on TNF-alpha and IFN gamma (TNF-alpha + IFN gamma) stimulation by HaCaT

Project description:G-protein coupled receptors (GPCRs) have diverse roles in physiological processes, including immunity. Gs-coupled GPCRs increase while Gi-coupled ones decrease intracellular cAMP. Previous studies suggest that, in epithelial cells, Gs-coupled GPCRs enhance whereas Gi-coupled GPCRs suppress pro-inflammatory immune responses. In order to examine the issue, we chose beta2 adrenergic receptor and GPR40 as representatives of Gs- and Gi- coupled GPCRs, respectively, and examined their effects on TNF-alpha and IFN-gamma-(TNF-alpha + IFN-gamma) induced gene expression by HaCaT. We used microarrays to detail the global changes of gene expression induced by a beta2 adrenergic receptor agonist terbutaline or GPR40 agonist GW9508 pre-treatment in TNF-alpha + IFN-gamma - stimulated HaCaT cells. HaCaT cells were pre-treated with terbutaline or GW9508, TNF-alpha + IFN-gamma were then added, and cultured for another 24 h. Cells were then used for RNA extraction and hybridization on Affymetrix microarrays. We sought to clarify changes in gene expression after 1) TNF-alpha + IFN-gamma, 2) TNF-alpha + IFN-gamma + terbutaline, and 3) TNF-alpha + IFN-gamma + GW9508 treatment. To this end, we set 4 groups of samples; 1) unstimulated group, 2) TNF-alpha + IFN-gamma-stimulated group, 3) TNF-alpha + IFN-gamma + terbutaline-stimulated group, and 4) TNF-alpha + IFN-gamma + GW9508-stimulated group. In each group, HaCaT cells were stimulated in triplicate wells (n=3).

Differential protein secretome induced by TNF-alpha

Project description:Endothelial-mesenchymal-transition (EndMT) is an important source of cancer-associated fibroblasts (CAFs), which are known to facilitate tumor progression. We have previously shown that EndMT is present in pancreatic tumors and that deficiency of the Tie1 receptor induces EndMT in human endothelial cells. Pancreatic tumors are characterized by the presence of tumor necrosis factor-α (TNF-α). We now show that TNF-α strongly induces human endothelial cells to undergo EndMT. In order to know the secretory feature of cells which undergo EndMT by TNF-α, we conducted a comparative analysis of HMVEC secretome treated or not for 24h and 48h with TNF-α. Secretome study shows that cells treated with TNF-α have an important fibroblast-like secretory capacity, and a proinflamatory signature. Moreover, Ingenuity Pathway Analysis (IPA) shows that pathways implicated in migration, inflammation and fibrosis are predicted to be activated and that necrosis and apoptosis pathways are inhibited. Accordingly cell survival, viability and cycle progression are activated. We show that TNF-α- treated cells secrete proteins related to 16 protumoral pathways, confirming their fibroblastic characteristic. Finally, among the predicted upstream regulators activated, IPA analysis shows that, TNFSF12 and its receptor are present at hight levels in PDAC patients. Altogether these results show the fibroblastic characteristic of treated cells and demonstrate that TNF-α induces CAFs.
