SWAP70 Promotes Atherosclerosis via Endothelial CAV1 Nuclear Translocation

ABSTRACT: Endothelial inflammation is a critical contributor to atherosclerosis and is tightly regulated by mechanical and inflammatory cues. Here, we identify SWAP70 as a key mechanosensitive adaptor protein involved in endothelial inflammatory responses. Using RNA-seq analysis of human umbilical vein endothelial cells (HUVECs) under three conditions—control (KOC), TNF-α stimulation (TKOC), and TNF-α stimulation with SWAP70 knockdown (TKO)—we demonstrate that SWAP70 deficiency profoundly alters the transcriptional landscape induced by TNF-α. SWAP70 knockdown suppresses the expression of key pro-inflammatory mediators such as VCAM1, MCP1, and CXCL8. Functional enrichment analysis reveals that SWAP70 regulates inflammation-related pathways including TNF, NF-κB, and MAPK signaling. These findings suggest that SWAP70 facilitates endothelial inflammation by promoting transcriptional responses to pro-inflammatory stimuli and may serve as a regulatory hub linking disturbed flow and cytokine signaling in atherosclerosis.

Inflammatory stress-mediated chromatin changes underlie dysfunction in endothelial cells. [RNA-Seq]

Project description:Inflammatory stresses underlie endothelial dysfunction and contribute to the development of chronic cardiovascular disorders such as atherosclerosis and vascular fibrosis. The initial transcriptional response of endothelial cells to pro-inflammatory cytokines such as TNF-alpha is well established. However, very few studies uncover the effects of inflammatory stresses on chromatin architecture. We used integrative analysis of ATAC-seq and RNA-seq data to investigate chromatin alterations in human endothelial cells in response to TNF-alpha and febrile-range heat stress exposure. Multi-omics data analysis suggests a correlation between the transcription of stress-related genes and endothelial dysfunction drivers with chromatin regions exhibiting differential accessibility.

Transcriptional reprogramming of tumor-associated endothelial cells by disruption of TNF-α signaling

Project description:Endothelial inflammation contributes to the pathogenesis of numerous human diseases; however, the role of tumor endothelial inflammation in the growth of experimental tumors and its influence on the prognosis of human cancers is less understood. TNF-α, an important mediator of tumor stromal inflammation, is known to target the tumor vasculature. In this study, we demonstrate that B16-F1 melanomas grew more rapidly in C57BL/6 wild-type (WT) mice than in syngeneic mice with germline deletions of both TNF-α receptors (KO). This enhanced tumor growth was associated with increased COX2 inflammatory expression in WT tumor endothelium compared to endothelium in KO mice. We purified endothelial cells from WT and KO tumors and characterized dysregulated gene expression, which ultimately formed the basis of a 6-gene Inflammation-Related Endothelial-derived Gene (IREG) signature. This inflammatory signature expressed in WT tumor endothelial cells was trained in human cancer datasets and predicted a poor clinical outcome in breast cancer, colon cancer, lung cancer and glioma. Consistent with this observation, conditioned media from human endothelial cells treated with pro-inflammatory cytokines (TNF-α and interferons) accelerated the growth of human colon and breast tumors in immune-deprived mice as compared with conditioned media from untreated endothelial cells. These findings demonstrate that activation of endothelial inflammatory pathways contributes to tumor growth and progression in diverse human cancers.

Analyzing small RNA sequences from canine stem cell-derived extracellular vesicles primed with TNF-α and IFN-γ

Project description:Acute lung injury is an acute inflammation disorder that disrupts the lung endothelial and epithelial barriers. In this study, we investigated the extracellular vesicles (EVs) obtained via priming inflammatory cytokines such as tumor necrosis factor (TNF)-α and interferon (IFN)-γ on canine adipose mesenchymal stem cells in improving their anti-inflammatory and/or immunosuppressive potential, and/or their ability to alleviate lipopolysaccharide-induced lung injury in vitro. We also explored the correlation between epithelial-to-mesenchymal transition and the inflammatory repressive effect of primed EVs. Using small RNA-Seq, we confirmed that miR-16 and miR-502 significantly increased in EVs from TNF-α and IFN-γ-primed canine adipose mesenchymal stem cells. The pro and anti-inflammatory cytokines were analyzed in a lipopolysaccharide-induced lung injury model and we found that the EV anti-inflammatory effect improved on priming with inflammatory cytokines. EVs obtained from primed stem cells effectively suppress endothelial-to-mesenchymal transition in a lung injury model. Our results suggest a potential therapeutic approach utilizing EVs obtained from adipose mesenchymal stem cells primed with TNF-α and IFN-γ against lung inflammation and endothelial to mesenchymal transition.

Investigate the role of MLKL in regulating TNF-induced endothelial cell inflammatory response

Project description:Purpose: Analyze the potential signaling pathways regulated by MLKL under TNF-induced endothelial cell inflammatory response Methods: HUVECs were allowed to grow to confluency and were starved with basal medium containing 0.5% FBS for 6h. Then treat HUVECs with vehicle, NSA, TNF-alpha, TNF-alpha+NSA for 6h and extract RNA. Results: NSA reduces the mRNA level of TNF-induced inflammation-related genes and most of these genes are downstream of NF-kappa B signaling pathway.

Genome-wide maps of RNA Polymerase II and p65 localization in HUVECs stimulated with TNF alpha

Project description:TNF alpha is one of the inflammatory mediator and induce genes mainly by transcriptional factor, p65, in endothelial cells. This time, we performed a time course study to detect the change of localization of p65 and Pol II. To identify p65 and Pol II binding sites, we used chromatin immunoprecipitation with deep sequencing (ChIP-seq) of HUVECs treated with or without TNF alpha for 30 mins. Cells were starved before stimulation longer than 16 hours. HUVECs were used within the first 6 passages. For crosslinking, 10 mM of EGS in 50% glacial acetic acid was used for 45 min, followed by 20 min of 1% paraformaldehyde treatmet was used.

Lack of tolerogenic CD11c+ cells drives early atherosclerosis [scRNA-seq]

Project description:Atherosclerosis is a chronic disease characterized by both dysregulated lipid metabolism and a sustained inflammatory reaction. To study exuberant inflammation as the main trigger of atherosclerosis, we established a novel in vivo approach to induce predominantly “immune-triggered atherosclerosis” for early atherogenesis independent of lipid dysregulation. Bone marrow from CD11c.DTR-GFP mice, which express the receptor for diphtheria toxin (DT) under control of the CD11c promoter, was transplanted into female C57BL/6 mice, and long-term depletion of antigen-presenting CD11c+ cells following DT administration was achieved without affecting lipid homeostasis. These mice exhibited enhanced atherosclerosis (~300%) in comparison to mice without CD11c+ cell depletion. Interestingly, we observed an altered immune cell composition within the aortic wall, including a decrease in tolerogenic DCs, a shift towards inflammatory Ly6G+/Ly6C+ monocytes and increased CD25+/FoxP3+ T cells, whereby the intracellular cytokine profile showed an increase of TNF- α, INF-γ and IL-17. We furthermore detected a pronounced systemic inflammatory response with increased levels of TNF-α, INFγ, IL-17 and IL-1β. Thus, CD11c+ cells are the decisive cellular brake preventing an exuberant inflammatory response in early atherogenesis. Here, we describe a novel tool for studying the role of immune cells and associated mechanisms in atherosclerosis in mice with intact lipid metabolism.

Transcriptomic changes in Human Umbilical Vein Endothelial Cells (HUVEC) after exposure to Tumor Necrosis Factor-Alpha(TNF-a), AdipoRon, and Sphingosine Kinase Inhibitor (SKI-I)

Project description:Endothelial dysfunction is one of the earliest manifestations of atherosclerosis development. Adiponectin, a hormone secreted by adipose tissue with insulin-sensitizing and anti-inflammatory properties, offers protection against atherosclerosis. The pleiotropic effects of adiponectin are thought to be mediated by the ceramidase activity of adiponectin receptors. Adiponectin has been shown to reduce ceramide levels in endothelial cells. Still, the effects of adiponectin on other sphingolipids and endothelial lipid metabolism are not completely elucidated. This study investigated the metabolic and sphingolipid alterations in endothelial cells linked to the protective effects of adiponectin against endothelial dysfunction. Human Umbilical Endothelial Cells (HUVECs) were treated with Tumor Necrosis Factor-alpha (TNF-α) to induce endothelial dysfunction. AdipoRon and SKI-I were used to study the effects of adiponectin and sphingosine kinase inhibition in HUVECs. Metabolic changes and sphingolipid alterations were assessed to understand changes in lipid metabolism, and RNA sequencing was used to quantify the transcriptomics changes.

Proteomic analysis of human eosinophils stimulated with IL-33 and TNF-alpha in addition to IL-5

Project description:Activated eosinophils is a major cell type to be involved in allergic diseases. IL-5 primarily activates eosinophils and prolongs their survival. Notably, inflammatory cytokines including IL-33 and TNF-alpha are also important to establish and augment its inflammatory process in type 2 inflammation. The aim of this study is to clarify the role of these cytokines as direct activators for human eosinophils.
