BACKGROUND: During severe sepsis, levels and activity of all coagulation proteins are reduced. Heparanase is implicated in angiogenesis and tumor progression. We previously demonstrated that heparanase also affected the hemostatic system. It forms a complex and increases the activity of the blood coagulation initiator tissue factor. AIM: To evaluate heparanase levels and procoagulant activity as predictors of sepsis severity. MATERIALS AND METHODS: Twenty one patients with non-trauma, non-surgical sepsis admitted to the Intensive Care Unit and 35 controls were recruited...

Emergence of the field of exosome biology has opened an exciting door to better understand communication between cells. These tiny nanovesicles act as potent regulators of biological function by delivering proteins, lipids and nucleic acids from the cell of origin to target cells. Recently, several enzymes including membrane-type 1 matrix metalloproteinase (MT1-MMP), insulin-degrading enzyme (IDE), sialidase and heparanase, among others, were localized on the surface of exosomes secreted by various cell types...

Heparan sulfate (HS) is an important component of the extracellular matrix and cell surface, which plays a key role in cell-cell and cell-matrix interactions. Functional activity of HS directly depends on its structure, which determined by a complex system of HS biosynthetic enzymes. During malignant transformation, the system can undergo significant changes, but for glioma, HS biosynthesis has not been studied in detail. In this study, we performed a comparative analysis of the HS biosynthetic system in human gliomas of different grades...

The heparan sulfate endoglycosidase heparanase (HPSE) is involved in tumor growth, chronic inflammation and fibrosis. Since a role for HPSE in chronic liver disease has not been demonstrated to date, the current study was aimed at investigating the involvement of HPSE in the pathogenesis of chronic liver injury. Herein, we revealed that HPSE expression increased in mouse livers after carbon tetrachloride (CCl4)-mediated chronic induction of fibrosis, but with a trend to decline during progression of the disease...

Substance abuse is a pressing problem with few therapeutic options. The identification of addiction resilience factors is a potential strategy to identify new mechanisms that can be targeted therapeutically. Heparan sulfate (HS) is a linear sulfated polysaccharide that is a component of the cell surface and extracellular matrix. Heparan sulfate modulates the activity and distribution of a set of negatively charged signaling peptides and proteins - known as the HS interactome - by acting as a co-receptor or alternative receptor for growth factors and other signaling peptides and sequestering and localizing them, among other actions...

In the diabetic heart, there is excessive dependence on FA utilization to generate ATP. Lipoprotein lipase (LPL)-mediated hydrolysis of circulating triglyceride (TG) is suggested to be the predominant source of FA for cardiac utilization during diabetes. In the heart, majority of LPL is synthesized in cardiomyocytes, and secreted onto cell surface heparan sulfate proteoglycans (HSPG), where an endothelial cell (EC) releasable β-endoglycosidase, heparanase, cleaves the side chains of HSPG to liberate LPL for its onward movement across the EC...

Heparanase activity is involved in cancer growth and development in humans and single nucleotide polymorphisms (SNPs) in the heparanase gene (HPSE) have been shown to be associated with tumors. In this study, we investigated whether SNPs in HPSE were a risk factor for hepatocellular carcinoma (HCC) by undertaking a comprehensive haplotype-tagging, case-control study. For this, six haplotype-tagging SNPs (htSNPs) in HPSE were genotyped in 400 HCC patients and 480 controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis...

PURPOSE: The protein tyrosine phosphatase PRL-3 plays an important role in cancer cell migration, invasion and metastasis. In breast cancer, PRL-3 is overexpressed in 70-75% of tumors and even more frequently in lymph node metastases. Moreover, PRL-3 overexpression in breast cancer is associated with an adverse disease outcome. Aim of this study was to determine the role of PRL-3 in breast cancer cell proliferation, migration and invasion in vitro. METHODS: PRL-3 mRNA expression was evaluated in 6 breast cancer cell lines by quantitative real-time PCR...

REVIEW
Shifaza Mohamed, Deirdre R Coombe
Heparin mimetics are synthetic and semi-synthetic compounds that are highly sulfated, structurally distinct analogues of glycosaminoglycans. These mimetics are often rationally designed to increase potency and binding selectivity towards specific proteins involved in disease manifestations. Some of the major therapeutic arenas towards which heparin mimetics are targeted include: coagulation and thrombosis, cancers, and inflammatory diseases. Although Fondaparinux, a rationally designed heparin mimetic, is now approved for prophylaxis and treatment of venous thromboembolism, the search for novel anticoagulant heparin mimetics with increased affinity and fewer side effects remains a subject of research...

Heparanase (HPSE) is part of the biologic network triggered by ischemia/reperfusion (I/R) injury, a complication of renal transplantation and acute kidney injury. During this period, the kidney or graft undergoes a process of macrophages recruitment and activation. HPSE may therefore control these biologic effects. We measured the ability of HPSE and its inhibitor, SST0001, to regulate macrophage polarization and the crosstalk between macrophages and HK-2 renal tubular cells during in vitro hypoxia/reoxygenation (H/R)...

Using syngeneic BALB/c mouse breast cancer models, we show that the chromatin remodeling subunit bromodomain PHD finger transcription factor (BPTF) suppresses natural killer (NK) cell antitumor activity in the tumor microenvironment (TME). In culture, BPTF suppresses direct natural cytotoxicity receptor (NCR) mediated NK cell cytolytic activity to mouse and human cancer cell lines, demonstrating conserved functions. Blocking mouse NCR1 in vivo rescues BPTF KD tumor weights, demonstrating its importance for the control of tumor growth...

Pancreatic cancer (PC), characterized by aggressive local invasion and metastasis, is one of the most malignant cancers. Gemcitabine is currently used as the standard drug for the treatment of advanced and metastatic PC, but with limited efficacy. In this study, we demonstrated that gemcitabine increased the expression of heparanase (HPA1), the only known mammalian endoglycosidase capable of cleaving heparan sulfate, both in vitro and in vivo. Furthermore, overexpression of HPA1 in PC cell lines enhanced proliferation and invasion, accompanied with elevated phosphorylation of EGFR...

Heparan sulfate (HS) is ubiquitously expressed on mammalian cells. It is a polysaccharide that binds growth factors, cytokines, and chemokines, and thereby controls several important physiological functions. Ironically, many human pathogens including viruses interact with it for adherence to host cells. HS functions can be regulated by selective modifications and/or selective cleavage of the sugar chains from the cell surface. In mammals, heparanase (HPSE) is the only known enzyme capable of regulating HS functions via a selective endoglycosidase activity that cleaves polymeric HS chains at internal sites...

In the vascular system, the endothelial surface layer (ESL) as the inner surface of blood vessels affects mechanotransduction, vascular permeability, rheology, thrombogenesis, and leukocyte adhesion. It creates barriers between endothelial cells and blood and neighbouring cells. The glycocalyx, composed of glycoconjugates and proteoglycans, is an integral component of the ESL and a key element in inter- and intracellular communication and tissue homeostasis. In pathophysiological conditions (atherosclerosis, infection, ischemia/reperfusion injury, diabetes, trauma and acute lung injury) glycocalyx-degrading factors, i...

Heparanase is an endoglucuronidase that uniquely cleaves the heparan sulfate side chains of heparan sulfate proteoglycans. This activity ultimately alters the structural integrity of the ECM and basement membrane that becomes more prone to cellular invasion by metastatic cancer cells and cells of the immune system. In addition, enzymatically inactive heparanase was found to facilitate the proliferation and survival of cancer cells by activation of signaling molecules such as Akt, Src, signal transducer and activation of transcription (Stat), and epidermal growth factor receptor...

The heparan sulfate-degrading enzyme heparanase promotes the progression of many cancers by driving tumor cell proliferation, metastasis and angiogenesis. Heparanase accomplishes this via multiple mechanisms including its recently described effect on enhancing biogenesis of tumor exosomes. Because we recently discovered that heparanase expression is upregulated in myeloma cells that survive chemotherapy, we were prompted to investigate the impact of anti-myeloma drugs on exosome biogenesis. When myeloma cells were exposed to the commonly utilized anti-myeloma drugs bortezomib, carfilzomib or melphalan, exosome secretion by the cells was dramatically enhanced...

Total joint arthroplasty (TJA) of the hip or knee (THA and TKA) is the primary surgical intervention for individuals with degenerative joint disease (DJD). Although it is commonly thought that shear force on the joint causes the degradation of articular cartilage, it is possible that there are other factors that contribute to the progression of DJD. It is plausible that specific enzymes that degrade the joint are upregulated, or conversely, there is downregulation of enzymes critical for joint lubrication. The aim of this study is to profile collagenase-1, elastase, heparanase, and lubricin levels in patients undergoing TJA in order to determine potential preexisting dysregulation that contributes to the pathogenesis of DJD...

INTRODUCTION: Impaired placental maturation has been associated with retention of fetal membranes, which is a major reproductive disease in cattle. This maturation includes alterations in all tissue compartments of the placenta, specifically of epithelial and stroma cells and extracellular matrix. It is believed to be controlled by hormones, adhesion molecules and proteolytic enzymes. To investigate if the proteolytic enzyme heparanase and its substrates, the syndecans (SDCs) could be involved in the release of fetal membranes, their expression in bovine placentomes was analyzed...
