Hepatic angiosarcoma is a mesenchymal tumor originating from liver sinusoidal endothelial cells. It is an extremely rare malignant neoplasm accounting for less than 1% of primary malignant liver tumors. The deregulated coagulopathy that can be seen in hepatic angiosarcoma fulfills the clinical diagnostic criteria of disseminated intravascular coagulation. However, the mechanism that governs this coagulopathy has been poorly understood. This case report provides histological evidence of the consumption of coagulation factors along with trapped platelets occurring within the tumor, which is the foundation for the concept of Kasabach-Merritt syndrome (KMS)...

Endothelial senescence has been suggested to promote endothelial dysfunction in age-related vascular disorders. This study evaluated the prothrombotic properties of senescent endothelial cells (ECs) and the underlying mechanism. Serial passaging from passage (P)1 to P4 (replicative senescence) of porcine coronary artery ECs, or treatment of P1 ECs with the endothelial nitric oxide synthase (eNOS) inhibitor L-NAME (premature senescence) induced acquisition of markers of senescence including increased senescence-associated-β-galactosidase (SA-β-gal) activity and p53, p21, p16 expression...

Idarubicin (IDR), cytarabine (AraC), and tamibarotene (Am80) are effective for treatment of acute myeloid leukemia (AML). In acute leukemia, the incidence of venous thromboembolism or disseminated intravascular coagulation is associated with induction chemotherapy. Procoagulant effects of IDR, AraC, and Am80 were investigated in a vascular endothelial cell line EAhy926 and AML cell lines HL60 (AML M2), NB4 (AML M3, APL), and U937 (AML M5), focusing on tissue factor (TF), phosphatidylserine (PS), and thrombomodulin (TM)...

Osteopontin (OPN) is a multifunctional matricellular protein produced by a broad range of cells including osteoclasts, macrophages, T cells, endothelial cells, and vascular smooth muscle cells. OPN modulates various physiological and pathological events such as inflammation, wound healing, and bone formation and remodeling. Dengue virus (DENV) infection causes an increase in plasma OPN levels, which is correlated with the severity of symptoms and coagulation abnormalities. DENV infection also induces OPN gene expression in human macrophages...

Astragaloside IV (AS-IV), a main active substance isolated from Astragalus membranaceus Bunge, has been shown to have multiple pharmacological effects. Endothelial cell protein C receptor (EPCR) is a marker of inflammation, and is also a major member of protein C (PC) anti-coagulation system. EPCR can be cut off from the cell surface by tumor necrosis factor-α converting enzyme (TACE), which is controlled through mitogen-activated protein kinase (MAPK) and protein kinase C (PKC) pathways. To develop novel therapeutic drug for EPCR shedding, the effect of AS-IV was studied in phorbol-12-myristate 13-acetate (PMA)-induced human umbilical vein endothelial cells (HUVECs) and the potential molecular mechanism of AS-IV action was investigated...

BACKGROUND: Estetrol (E4) is a natural estrogen produced solely during human pregnancy. E4 is suitable for clinical use since it acts as a selective estrogen receptor modulator. In clinical trials E4 has been seen to have little or no effect on coagulation. Hence, it is interesting to investigate whether E4 alters endothelial-dependent fibrinolysis. OBJECTIVES: We studied the effects of E4 on the fibrinolytic system and whether this could influence the ability of endothelial cells to migrate...

Background: Mortality rates remain high for human immunodeficiency virus (HIV)-associated tuberculosis, and our knowledge of contributing mechanisms is limited. We aimed to determine whether hemostatic changes in HIV-tuberculosis were associated with mortality or decreased survival time and the contribution of mycobacteremia to these effects. Methods: We conducted a prospective study in Khayelitsha, South Africa, in hospitalized HIV-infected patients with CD4 cell counts <350/µL and microbiologically proved tuberculosis...

Female gender, post-menopause, chronic kidney disease (CKD) and (CKD linked) microvascular disease are important risk factors for developing heart failure with preserved ejection fraction (HFpEF). Enhancing our understanding of the interrelation between these risk factors could greatly benefit the identification of new drug targets for future therapy. This review discusses the evidence for the protective role of estradiol (E2) in CKD-associated microvascular disease and related HFpEF. Elevated circulating levels of uremic toxins (UTs) during CKD may act in synergy with hormonal changes during post-menopause and could lead to coronary microvascular endothelial dysfunction in HFpEF...

BACKGROUND: Systemic vascular endothelial injury is a consequence of trauma-hemorrhagic shock (T/HS) which results in disturbances of coagulation, inflammation and endothelial barrier integrity. The effect of T/HS on the endothelium (Endotheliopathy of Trauma)[EoT] is of intense research interest and may lead to EoT directed therapies. Administration of tranexamic acid (TXA) in trauma patients is associated with a survival benefit and fewer complications if given early after injury. Mechanisms for this protective effect include the anti-fibrinolytic and anti-inflammatory effects of TXA...

Cluster of differentiation 14 (CD14), a pattern recognition receptor expressed on myeloid cells and a critical component of the innate immune system, mediates local and systemic host responses to gram-negative bacterial products, including lipopolysaccharide (LPS). Therefore, CD14 is an attractive target for development of sepsis therapies, and several monoclonal anti-CD14 antibodies have been reported. In this study, we prepared an anti-human CD14 monoclonal antibody, F1024-1-3, which suppressed LPS-induced upregulation of pro-inflammatory cytokines and an adhesion molecule in human peripheral mononuclear cells and human vascular endothelial cells...

Circulatory hypoxia-related diseases (CHRDs), including acute coronary syndromes, stroke and organ transplantation, attract increased attention due to high morbidity and mortality. Mounting evidence shows that hypoxia-induced oxidative stress, coagulation, inflammation and angiogenesis play extremely important roles in the physiological and pathological processes of CHRD-related vascular endothelial injury. Interestingly, hypoxia, even hypoxia-induced oxidative stress, coagulation and inflammation can all induce release of endothelial microparticles (EMPs)...

Prothrombin and its active derivative thrombin are key members of the coagulation system. The only site of extra-hepatic thrombin expression is the central nervous system (CNS), where it is involved in brain development, protection, and regeneration. Thrombin affects various degenerative and ischemic CNS diseases like Alzheimer's, multiple sclerosis, cerebral ischemia, and hemorrhage in a dose dependent manner. Additionally, the association of thrombin with various malignancies has recently become evident. Thrombin facilitates the interaction between tumor cells with platelets, endothelial cells, and the adhesion to matrix proteins in various tumor types...

Activated factor X (FXa) plays an important role in thrombin generation and inflammation. Factor X is not converted constitutively to FXa, but only after intrinsic clotting factors are activated and/or cellular injury occurs. Although rivaroxaban is one of direct FXa inhibitors, its function in the inactivated coagulation cascade is unclear. In human umbilical vein endothelial cells that natively express protease-activated receptor-1 and -2, high dose rivaroxaban did not alter gene transcripts including pro-inflammatory genes in DNA microarray...

BACKGROUND: Pro-inflammatory cytokines play important pathological effects in various diseases and allotransplantation; however, their pathological role in xenotransplantation remains elusive. In pig-to-human cell or organ transplantation, whether porcine cells or organs are activated by human cytokines or not as an important question needs to be investigated. METHODS: We investigated the effect of human IL-6, IFN-γ, IL-17, IL-1β, and TNF-α in xenotransplantation using several in vitro models and porcine aortic endothelial cells (PAECs) as target cells...
