Project description:Deep vein thrombosis (DVT), the third most common cause of cardiovascular deaths, is characterized by intravascular clot formation, often accompanied by inflammation. Although the Stimulator of Interferon Genes (STING) signaling pathway has gained recognition as a central mediator of inflammation in the context of infection, cellular stress, and tissue, its intricate involvement in DVT remains enigmatic. Here, we demonstrate that STING inhibition via specific inhibitors or myeloid-specific STING deficiency ameliorated thrombus formation in murine DVT models. Furthermore, our findings uncover a direct interaction between STING and YBX1, resulting in nuclear translocation and enhanced thrombotic inflammation. A synthetic peptide, C-ST16, designed to resemble STING inhibitors, exhibits promising therapeutic potential by effectively reducing thrombus formation and diminishing inflammatory factor expression without the hepatorenal toxicity. Overall, these findings shed light on the interplay between myeloid specific STING-YBX1 and inflammation, offering novel therapeutic insights for DVT management.

Project description:Deep vein thrombosis (DVT) is a common clinical problem, but its cellular and molecular mechanisms remain incompletely understood. We performed single-cell RNA sequencing (scRNA-seq) on the vein wall of mouse inferior vena cava (IVC) ligation model of deep vein thrombosis (DVT), to analyze the transcriptomic changes in the vein wall during acute venous thrombosis.

Project description:Portal vein tumor thrombosis is a strong poor indication of HCC. Characterizing the molecular alterations of these metastatic HCCs is important for understanding the molecular mechanisms during HCC progression and metastasis. Previous genomic studies mainly focus on single molecular layer, such as gene expressions or exonic mutations. In this study, we systematically examined the copy number variation (CNV), DNA methylation, miRNA and transcriptome of matched adjacent normal tissues, primary tumors and PVTTs from 19 HCC patients. Based on the integrative multi-omics profiles, we established the molecular landscape of the metastatic HCCs and identified a set of the recurrent genomic alterations and candidate driver genes.

Project description:Arterial and venous (A/V) thrombosis constitutes the greatest source of morbidity and mortality worldwide. Long considered as distinct entities, accumulating evidence indicates that A/V thrombosis can occur in the same populations suggesting that common mechanisms are likely operative. Although hyperactivation of the immune system is a common forerunner to the genesis of thrombotic events in both vascular systems, the key molecular control points remain poorly understood. Consequently, anti-thrombotic therapies targeting the immune system for therapeutic gain are lacking. Here we show that neutrophils are key effectors of both A/V thrombosis and can be targeted via novel immunoregulatory nanoparticles. Using antiphopholipid antibody syndrome (APS) as a model for devastating A/V thrombosis, we identified the transcription factor Krüppel-like factor 2 (KLF2) as a key regulator of neutrophil activation. Upon activation via genetic loss of KLF2 or administration of antiphospholipid antibodies, neutrophils cluster P-selectin glycoprotein ligand 1 (PSGL-1) via cortical actin remodeling, thereby increasing adhesion potential at thrombosis sites. Targeting clustered PSGL-1 using designer nanoparticles attenuates neutrophil-mediated A/V thrombosis in APS and KLF2 knockout models, illustrating the importance and feasibility of targeting activated neutrophils to prevent pathological thrombosis. Together, our results demosntrate a role for activated neutrophils to prevent pathological thrombosis. Together, our results demonstrate a role for activated neutorphils in both arterial and venous thrombosis and identify key molecular events that serve as potential targets for therapeutics against diverse causes of immunothrombosis.
