Dental pulp mesenchymal stem cells-response to fibrin hydrogel reveals ITGA2 and MMPs expression. Heliyon 2024; 10:e32891. [PMID: 39027533 PMCID: PMC11255596 DOI: 10.1016/j.heliyon.2024.e32891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 06/07/2024] [Accepted: 06/11/2024] [Indexed: 07/20/2024] Open
Abstract
Regenerative endodontic procedures (REP) aim at reestablishing tooth vitality by replacing the irreversibly damaged dental pulp removed by the dental practitioner with a new functional one. The current treatment of advanced caries relies on the replacement of the inflamed or necrosed dental pulp with an inert filling material. This leads to a functional but non-vital tooth, which lacks the ability to sense dental tissue damage, and to protect from further bacterial attack. Therapeutic strategies inspired by tissue engineering called REP propose to regenerate a fully functional dental pulp directly in the canal space. Promising results were obtained using dental pulp mesenchymal stem cells (DP-MSCs) in combination with bio-inspired artificial and temporary 3D hydrogels made of extracellular matrix molecules such as collagen and fibrin biomacromolecules. However, the uncontrolled mechanisms of DP regeneration from DP-MSCs in 3D biomacromolecules fail to regenerate a fully functional DP and can induce fibrotic scarring or mineralized tissue formation to a non-negligible extent. The lack of knowledge regarding the early molecular mechanisms initiated by DP-MSCs seeded in ECM-made hydrogels is a scientific lock for REP. In this study, we investigated the early DP-MSC-response in a 3D fibrin hydrogel. DP-MSCs isolated from human third molars were cultured for 24 h in the fibrin hydrogel. The differential transcript levels of extracellular and cell surface genes were screened with 84-gene PCR array. Out of the 84 genes screened, 9 were found to be overexpressed, including those coding for the integrin alpha 2 subunit, the collagenase MMP1 and stromelysins MMP3, MMP10 and MMP12. Over-expression of ITGA2 was confirmed by RT-qPCR. The expression of alpha 2 integrin subunit protein was assessed over time by immunoblot and immunofluorescence staining. The increase in the transcript level of MMP1, MMP3, MM10 and MMP12 was confirmed by RT-qPCR. The overexpression of MMP1 and 3 at the protein level was assessed by immunoblot. MMP3 expression by DP-MSCs was observed by immunofluorescence staining. This work demonstrates overexpression of ITGA2 and of MMP1, 3, 10 and 12 by DP-MSCs cultured in a fibrin hydrogel. The main preliminary extracellular and cell surface response of the DP-MSCs to fibrin hydrogel seems to rely on a ITGA2/MMP3 axis. Further investigations are needed to precisely decipher the role of this axis in dental pulp tissue building. Nevertheless, this work identifies extracellular and cell surface molecules that could be potential checkpoints to be targeted to guide proper dental pulp tissue regeneration.

The procoagulant signature of cancer cells drives fibrin network formation in tumor microenvironment and impacts its quality. Implications in cancer cell migration and the resistance to anticancer agents. Thromb Res 2024; 238:172-183. [PMID: 38723522 DOI: 10.1016/j.thromres.2024.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/02/2024] [Accepted: 04/15/2024] [Indexed: 05/21/2024]
Abstract
INTRODUCTION Cancer cells induce hypercoagulability in the tumoral microenvironment by expressing Tissue Factor (TF). We aimed to study the impact of the procoagulant signature of cancer cells on the quality and structure of fibrin network. We also studied the impact of fibrin clot shield (FCS) on the efficiency of anticancer agents and the migration of cancer cells. MATERIALS AND METHODS Pancreatic cancer cells BXPC3 and breast cancer cells MDA-MB231 and MCF7, were cultured in the presence of normal Platelet Poor Plasma (PPP), diluted 10 % in conditioning media. Their potential to induce thrombin generation and their fibrinolytic activity were assessed. The structure of fibrin network was analyzed with Scanning Electron Microscopy (SEM). Cancer cells' mobility with fibrin clot and their interactions with fibrin were observed. Cancer cells were treated with paclitaxel (PTX) or 4-hydroxy-tamoxifen (4OHTam) in the presence or absence of FCS. RESULTS Cancer cells, in presence of PPP, induced fibrin network formation. High TF-expressing cancer cells (BXPC3 and MDA-MB23 cells), led to dense fibrin network with fine fibers. Low TF expressing cells MCF7 led to thick fibers. Exogenous TF enhanced the density of fibrin network formed by MCF7 cells. Cancer cells through their inherent profibrinolytic potential migrated within the fiber scaffold. The BXPC3 and MCF7 cells moved in clusters whereas the MDA-MB231 cells moved individually within the fibrin network. FCS decreased the efficiency of PTX and 4OHTam on the viability of cancer cells. CONCLUSIONS The procoagulant signature of cancer cells is determinant for the quality and structure of fibrin network in the microenvironment. Original SEM images show the architecture of "bird's nest"-like fibrin network being in touch with the cell membranes and surrounding cancer cells. Fibrin network constructed by triggering thrombin generation by cancer cells, provides a scaffold for cell migration. Fibrin clot shields protect cancer cells against PTX and 4OHTam.

Abstract
Three-dimensional (3D) matrix models using hydrogels are powerful tools to understand and predict cell behavior. The interactions between the cell and its matrix, however is highly complex: the matrix has a profound effect on basic cell functions but simultaneously, cells are able to actively manipulate the matrix properties. This (mechano)reciprocity between cells and the extracellular matrix (ECM) is central in regulating tissue functions and it is fundamentally important to broadly consider the biomechanical properties of the in vivo ECM when designing in vitro matrix models. This manuscript discusses two commonly used biopolymer networks, i.e. collagen and fibrin gels, and one synthetic polymer network, polyisocyanide gel (PIC), which all possess the characteristic nonlinear mechanics in the biological stress regime. We start from the structure of the materials, then address the uses, advantages, and limitations of each material, to provide a guideline for tissue engineers and biophysicists in utilizing current materials and also designing new materials for 3D cell culture purposes.

Abstract
Early and late thrombosis remain the most frequent reasons for the failure of synthetic cardiovascular grafts. Long-term hemocompatibility of implanted synthetic grafts can be achieved if a natural living endothelium is formed over its blood-contacting surface. Here we present a modification of a standard expanded polytetrafluorethylene (ePTFE) vessel prosthesis by a controlled preparation of a fibrin mesh enriched with covalently bound heparin and noncovalently bound vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). Compared to a bare prosthesis, the coated prosthesis showed excellent antithrombogenic properties after contact with heparinized fresh human blood. Human umbilical vein endothelial cells seeded on the inner surface of the coated prosthesis formed a confluent layer in 5 days, whereas only small colonies of cells were scattered on the bare prosthesis. Viability of the cells was promoted mainly by FGF immobilized on the coating. These findings suggest that the coating may prevent acute thrombus formation and support the self-endothelialization of an implanted ePTFE vascular graft in vivo.

Abstract
The roles of protein conformational dynamics and allostery in function are well-known. However, the roles that interdomain dynamics have in function are not entirely understood. We used matrix metalloprotease-1 (MMP1) as a model system to study the relationship between interdomain dynamics and activity because MMP1 has diverse substrates. Here we focus on fibrin, the primary component of a blood clot. Water-soluble fibrinogen, following cleavage by thrombin, self-polymerize to form water-insoluble fibrin. We studied the interdomain dynamics of MMP1 on fibrin without crosslinks using single-molecule Forster Resonance Energy Transfer (smFRET). We observed that the distance between the catalytic and hemopexin domains of MMP1 increases or decreases as the MMP1 activity increases or decreases, respectively. We modulated the activity using (1) an active site mutant (E219Q) of MMP1, (2) MMP9, another member of the MMP family that increases the activity of MMP1, and (3) tetracycline, an inhibitor of MMP1. We fitted the histograms of smFRET values to a sum of two Gaussians and the autocorrelations to an exponential and power law. We modeled the dynamics as a two-state Poisson process and calculated the kinetic rates from the histograms and autocorrelations. Activity-dependent interdomain dynamics may enable allosteric control of the MMP1 function.

Abstract
This review focuses on fibrin, starting from biological mechanisms (its production from fibrinogen and its enzymatic degradation), through its use as a medical device and as a biomaterial, and finally discussing the techniques used to add biological functions and/or improve its mechanical performance through its molecular engineering. Fibrin is a material of biological (human, and even patient's own) origin, injectable, adhesive, and remodellable by cells; further, it is nature's most common choice for an in situ forming, provisional matrix. Its widespread use in the clinic and in research is therefore completely unsurprising. There are, however, areas where its biomedical performance can be improved, namely achieving a better control over mechanical properties (and possibly higher modulus), slowing down degradation or incorporating cell-instructive functions (e.g., controlled delivery of growth factors). The authors here specifically review the efforts made in the last 20 years to achieve these aims via biomimetic reactions or self-assembly, as much via formation of hybrid materials.

Abstract
Nephropathia Epidemica (NE), a mild form of hemorrhagic fever with renal syndrome (HFRS) and linked to hantavirus infection, is endemic in the Republic of Tatarstan. Several genetic markers of HFRS severity have been identified previously, including human leukocyte antigen (HLA) complexes and nucleotide polymorphism in the tumor necrosis factor alpha (TNFα) gene. Still, our understanding of the genetic markers of NE severity remains incomplete. The frequency of the C-C chemokine receptor type 5 (CCR5) gene wild type and gene with 32-base-pair deletion (Δ32CCR5) genotypes in 98 NE samples and 592 controls was analyzed using PCR. Along with the serum levels of 94 analytes, a lack of differences in the CCR5 genotype distribution between NE cases and the general population suggests that the CCR5 genotype does not affect susceptibility to hantavirus infection. However, in NE cases, significant variation in the serum levels of the host matrix metalloproteases between functional CCR5 homozygous and Δ32CCR5 heterozygous patients was detected. Also, the oliguric phase was longer, while thrombocyte counts were lower in functional CCR5 homozygous as compared to heterozygous NE cases. Our data, for the first time, presents the potential role of the CCR5 receptor genotype in NE pathogenesis. Our data suggests that NE pathogenesis in functional CCR5 homozygous and heterozygous NE patients differs, where homozygous cases may have more disintegration of the extracellular matrix and potentially more severe disease.

Abstract
Myxomatous mitral valve disease is the most common cardiac disease of the dog, but examination of the associated cellular and molecular events has relied on the use of cadaveric valve tissue, in which functional studies cannot be undertaken. The aim of this study was to develop a three-dimensional (3D) cell co-culture model as an experimental platform to examine disease pathogenesis. Mitral valve interstitial (VIC) and endothelial (VEC) cells were cultured from normal and diseased canine (VIC only) valves. VICs were embedded in a fibrin-based hydrogel matrix and one surface was lined with VECs. The 3D static cultures (constructs) were examined qualitatively and semiquantitatively by light microscopy, immunofluorescence microscopy and protein immunoblotting. Some constructs were manipulated and the endothelium damaged, and the response examined. The construct gross morphology and histology demonstrated native tissue-like features and comparable expression patterns of cellular (α-smooth muscle actin [SMA] and embryonic smooth muscle myosin heavy chain [SMemb]) and extracellular matrix associated markers (matrix metalloproteinase [MMP]-1 and MMP-3), reminiscent of diseased valves. There were no differences between constructs containing normal valve VICs and VECs (type 1) and those containing diseased valve VICs and normal valve VECs (type 2). Mechanical manipulation and endothelial damage (type 3) tended to decrease α-SMA and SMemb expression, suggesting reversal of VIC activation, but with retention of SMemb+ cells adjacent to the wounded endothelium consistent with response to injury. Fibrin-based 3D mitral valve constructs can be produced using primary cell cultures derived from canine mitral valves, and show a phenotype reminiscent of diseased valves. The constructs demonstrate a response to endothelial damage indicating their utility as experimental platforms.

Abstract
OBJECTIVE Herbal extract compositions are largely used to manage vein diseases. We prepared a new composition of herbs, named FLEBO OK™, that, when administered as a nutraceutical to patients affected by peripheral vascular diseases, was able to improve their health conditions. We analyzed the effects of this nutraceutical composition on in vitro cultured cells with the aim to obtain information about its mechanisms of action. METHODS A culture of human osteoblast cell line Saos-2 was stimulated with tumor necrosis factor (TNF)-α or interleukin (IL)-1β to induce the expression of some chemokines and matrix metalloproteases (MMPs). This cell culture was then exposed to the prepared composition and the amount of expression of the genes coding for the monocyte chemotactic protein (MCP)-1, IL-8, IL-1β, MMP-2, MMP-3, MMP-9 proteins was measured by real-time polymerase chain reaction (RT-PCR). The experiments were repeated exposing the cells to the same amount of the well-known micronized purified flavonoid fraction. Moreover, we describe the effects of the administration of nutraceutical composition to 20 patients affected by peripheral vascular diseases and 20 healthy individuals. RESULTS The RT-PCR analyses showed that the new composition induces the expression of MMP-3 and MMP-9 and downregulates MMP-2 in cell cultures stimulated with IL-1β, whereas it induces the expression of IL-8 and represses the expression of IL-1β and MCP-1 in cell cultures stimulated with TNF-α. The induction of the expression of MMP-3 and the downregulation of MCP-1 might result in an antiplatelet activity that was not observed for the micronized purified flavonoid fraction. Interviewed patients reported an improvement in their conditions after 1 month of FLEBO OK treatment. CONCLUSION These findings could provide a hypothesis for the high efficiency of the identified nutraceutical composition to management of peripheral vascular diseases.

Abstract
While commonly known for degradation of the extracellular matrix, matrix metalloproteinases (MMPs) exhibit broad potential for use in targeting of bioactive and imaging agents in cancer treatment. MMPs are upregulated at all stages of expression in cancers. A comprehensive analysis of published literature on expression of all MMP subtypes at the genetic, protein, and activity levels in normal and diseased tissues indicate targeting applicability in a variety of cancers. This expression significantly increases at advanced cancer stages, providing an improved opportunity for controlled release in higher-stage patients. Since MMPs are integral at every stage of metastasis, MMP roles in cancer are discussed with a focus on MMP distribution and mobility within cells and tumors for cancer targeting applications. Several strategies for MMP utilization in targeting - such as matrix degradation, MMP cleavage, MMP binding, and MMP-induced environmental changes - are addressed.

Abstract
PURPOSE To determine whether the delivery of recombinant truncated plasminogen activator inhibitor-1 (PAI-1) protein (rPAI-1(23)) would protect from the development of radiation-induced lung injury. METHODS AND MATERIALS C57Bl/6 mice received intraperitoneal injections of rPAI-1(23) (5.4 μg/kg/d) or vehicle for 18 weeks, beginning 2 days before irradiation (IR) (5 daily fractions of 6 Gy). Cohorts of mice were followed for survival (n=8 per treatment) and tissue collection (n=3 per treatment and time point). Fibrosis in lung was assessed with Masson-Trichrome staining and measurement of hydroxyproline content. Senescence was assessed with staining for β-galactosidase activity in lung and primary pneumocytes. RESULTS Hydroxyproline content in irradiated lung was significantly reduced in mice that received rPAI-1(23) compared with mice that received vehicle (IR+vehicle: 84.97 μg/lung; IR+rPAI-1(23): 56.2 μg/lung, P=.001). C57Bl/6 mice exposed to IR+vehicle had dense foci of subpleural fibrosis at 19 weeks, whereas the lungs of mice exposed to IR+rPAI-1(23) were largely devoid of fibrotic foci. Cellular senescence was significantly decreased by rPAI-1(23) treatment in primary pneumocyte cultures and in lung at multiple time points after IR. CONCLUSIONS These studies identify that rPAI-1(23) is capable of preventing radiation-induced fibrosis in murine lungs. These antifibrotic effects are associated with increased fibrin metabolism, enhanced matrix metalloproteinase-3 expression, and reduced senescence in type 2 pneumocytes. Thus, rPAI-1(23) is a novel therapeutic option for radiation-induced fibrosis.

Abstract
BACKGROUND Post-stroke depression (PSD) is the most common psychiatric complication facing stroke survivors and has been associated with increased distress, physical disability, poor rehabilitation, and suicidal ideation. However, the pathophysiological mechanisms underlying PSD remain unknown, and no objective laboratory-based test is available to aid PSD diagnosis or monitor progression. METHODS Here, an isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomic approach was performed to identify differentially expressed proteins in plasma samples obtained from PSD, stroke, and healthy control subjects. RESULTS The significantly differentiated proteins were primarily involved in lipid metabolism and immunoregulation. Six proteins associated with these processes--apolipoprotein A-IV (ApoA-IV), apolipoprotein C-II (ApoC-II), C-reactive protein (CRP), gelsolin, haptoglobin, and leucine-rich alpha-2-glycoprotein (LRG)--were selected for Western blotting validation. ApoA-IV expression was significantly upregulated in PSD as compared to stroke subjects. ApoC-II, LRG, and CRP expression were significantly downregulated in both PSD and HC subjects relative to stroke subjects. Gelsolin and haptoglobin expression were significantly dysregulated across all three groups with the following expression profiles: gelsolin, healthy control>PSD>stroke subjects; haptoglobin, stroke>PSD>healthy control. CONCLUSIONS Early perturbation of lipid metabolism and immunoregulation may be involved in the pathophysiology of PSD. The combination of increased gelsolin levels accompanied by decreased haptoglobin levels shows promise as a plasma-based diagnostic biomarker panel for detecting increased PSD risk in post-stroke patients.

Abstract
Matrix metalloproteinases (MMPs) are a large family of proteases involved in many cell-matrix and cell-cell signalling processes through activation, inactivation or release of extracellular matrix (ECM) and non-ECM molecules, such as growth factors and receptors. Uncontrolled MMP activities underlie the pathophysiology of many disorders. Also matrix metalloproteinase-3 (MMP-3) or stromelysin-1 contributes to several pathologies, such as cancer, asthma and rheumatoid arthritis, and has also been associated with neurodegenerative diseases like Alzheimer's disease, Parkinson's disease and multiple sclerosis. However, based on defined MMP spatiotemporal expression patterns, the identification of novel candidate molecular targets and in vitro and in vivo studies, a beneficial role for MMPs in CNS physiology and recovery is emerging. The main purpose of this review is to shed light on the recently identified roles of MMP-3 in normal brain development and in plasticity and regeneration after CNS injury and disease. As such, MMP-3 is correlated with neuronal migration and neurite outgrowth and guidance in the developing CNS and contributes to synaptic plasticity and learning in the adult CNS. Moreover, a strict spatiotemporal MMP-3 up-regulation in the injured or diseased CNS might support remyelination and neuroprotection, as well as genesis and migration of stem cells in the damaged brain.

Abstract
Rearrangement of the skin during wound healing depends on plasmin and plasminogen, which serve to degrade fibrin depositions in the provisional matrix and thereby facilitate keratinocyte migration. In the current study, we investigated whether plasmin and plasminogen likewise played a role during the development of skin cancer. To test this, we set up a chemically induced skin tumor model in a cohort of mice and found that skin tumor growth in Plg(-/-) male mice was reduced by 52% compared with wild-type controls. Histological analyses suggested that the growth-restricting effect of plasminogen deficiency was due to thrombosis and lost patency of the tumor vasculature, resulting in tumor necrosis. The connection between plasmin-dependent fibrinolysis, vascular patency, and tumor growth was further substantiated as the effect of plasminogen deficiency on tumor growth could be reverted by superimposing heterozygous fibrinogen deficiency on Plg(-/-) mice. Tumors derived from these Fib(-/+);Plg(-/-) mice displayed a significantly decreased level of tumor thrombosis compared with Plg(-/-) mice. In summary, these data indicate that plasmin-driven fibrinolysis facilitates tumor growth by maintaining patency of the tumor vasculature.

Abstract
To address the need for the development of bioengineered replacement of a nerve graft, a novel two component fibrin glue conduit was combined with human mesenchymal stem cells (MSC) and immunosupressive treatment with cyclosporine A. The effects of MSC on axonal regeneration in the conduit and reaction of activated macrophages were investigated using sciatic nerve injury model. A 10mm gap in the sciatic nerve of a rat was created and repaired either with fibrin glue conduit containing diluted fibrin matrix or fibrin glue conduit containing fibrin matrix with MSC at concentration of 80×10(6) cells/ml. Cells were labeled with PKH26 prior to transplantation. The animals received daily injections of cyclosporine A. After 3 weeks the distance of regeneration and area occupied by regenerating axons and ED1 positives macrophages was measured. MSC survived in the conduit and enhanced axonal regeneration only when transplantation was combined with cyclosporine A treatment. Moreover, addition of cyclosporine A to the conduits with transplanted MSC significantly reduced the ED1 macrophage reaction.

Abstract
Osteoarthritis is a progressive joint disease characterized by cartilage degradation and bone remodelling. Under physiologic conditions, articular cartilage displays a stable chondrocyte phenotype, whereas in osteoarthritis a chondrocyte hypertrophy develops near the sites of cartilage surface damage and associates to the pathologic expression of type X collagen. Transglutaminases (TGs) include a family of Ca(2+)-dependent enzymes that catalyze the formation of γ-glutamyl cross-links. Their substrates include a variety of intracellular and extracellular macromolecular components. TGs are ubiquitously and abundantly expressed and implicated in a variety of physiopathological processes. TGs activity is modulated by inflammatory cytokines. TG2 (also known as tissue transglutaminase) mediates the hypertrophic differentiation of joint chondrocytes and interleukin-1-induced calcification. Histomorphometrical and biomolecular investigations document increased TG2 expression in human and experimental osteoarthritis. Consequently, the level of TG2 expression may represent an adjuvant additional marker to monitor tissue remodelling occurring in osteoarthritic joint tissue. Experimental induction of osteoarthritis in TG2 knockout mice is followed from reduced cartilage destruction and increased osteophyte formation compared to wild-type mice, suggesting a different influence on joint bone and cartilage remodelling. The capacity of transamidation by TG2 to regulate activation of latent TGF-β seems to have a potential impact on the regulation of inflammatory response in osteoarthritic tissues. Additional studies are needed to define TG2-regulated pathways that are differently modulated in osteoblasts and chondrocytes during osteoarthritis.

Abstract
Background To date, recombinant tissue plasminogen activator (rtPA) is the only approved drug for ischemic stroke. It is intravenously administered functioning as a thrombolytic agent and is used to obtain reperfusion of the affected area of the brain. Excitotoxicity, inflammation and apoptosis are all involved in delayed neuronal death following stroke and offer multiple opportunities to intervene with neuroprotective agents. Gelsolin (GSN) is an actin- and calcium-binding protein mediating the disassembly of actin filaments and activity of calcium channels. It also functions as a regulator of apoptosis and inflammatory responses. This study tests the hypothesis that increasing the concentration of the form of GSN known as plasma GSN (pGSN) near an infarct will provide neuroprotection following ischemic stroke. Methods We induced middle cerebral artery occlusion (MCAO) in male rats via intracranial injection of endothelin-1 (ET-1), a potent vasoconstrictor, and then treated with local delivery of pGSN. Whole brain laser Doppler perfusion imaging was performed through the skull to assess MCAO effectiveness. Cylinder and vibrissae tests evaluated sensorimotor function before and 72 h after MCAO. Infarct volumes were examined 72 h after MCAO via 2, 3, 5-triphenyltetrazolium chloride (TTC) assay. Results Estimates of relative cerebral perfusion were significantly decreased in all groups receiving MCAO with no differences detected between treatments. Despite equivalent initial strokes, the infarct volume of the pGSN treatment group was significantly reduced compared with the untreated MCAO rats at 72 h. ET-1 induced significant deficits in both cylinder and vibrissae tests while pGSN significantly limited these deficits. Conclusion Gelsolin could be a promising drug for protection against neurodegeneration following ischemic stroke.

Abstract
Injured peripheral nerve tissue could benefit from biomaterial nerve guidance conduits (NGCs) that are designed to promote neuronal regeneration. Nerve regeneration is a complex multi-step process that involves the remodeling of the ECM surrounding the regenerating neural tissue. Hydrogel biomaterials have been used as provisional matrices to regulate this regeneration process by providing the desired physical properties and controllable degradation characteristics. The purpose of this investigation was to understand the mechanism by which nerve cells penetrate into a hydrogel made from PEGylated fibrinogen. In this context, the dorsal root ganglion (DRG) assay was used as an in vitro model to study the cellular invasion behavior of both neural and nonneuronal cells. Our hypothesis stipulated that DRG cells employ matrix metalloproteinases (MMPs) in order to degrade the dense hydrogel matrix and penetrate the biomaterial. Three dimensional (3D) DRG-hydrogel constructs were cultured with MMP inhibitors (MMPi) and the effect of the inhibitors on DRG cell outgrowth was investigated. We also examined the effect of inhibitors on two dimensional (2D) DRG cell outgrowth on PEGylated fibrinogen hydrogels and on tissue culture polystyrene (TCP). Our results demonstrate that DRG cell outgrowth into and onto PEGylated fibrinogen hydrogels was inhibited by MMPi and that the outgrowth characteristics was dependent on the type of inhibitor and its concentration. MMP-3i and MMP-8i decreased both neuronal and nonneuronal outgrowth, where MMP-3i had a stronger inhibitory effect on nonneuronal cells. MMP-2/9i, on the other hand, affected the neuronal outgrowth much more than the others. We concluded that MMPs play a central role in the process of DRG cell penetration into PEGylated fibrinogen hydrogels and may also regulate the adhesion, migration and elongation of neuronal cells on the surface of these hydrogel biomaterials.

Abstract
Background Acute-phase response involves the simultaneous altered expression of serum proteins in association to inflammation, infection, injury or malignancy. Studies of the acute-phase response usually involve determination of the levels of individual acute-phase serum proteins. In the present study, the acute-phase response of patients with epithelial (EOCa) and germ-line (GOCa) ovarian carcinoma was investigated using the gel-based proteomic approach, a technique which allowed the simultaneous assessment of the levels of the acute-phase serum high abundance proteins. Data obtained were validated using ELISA and immunostaining of biopsy samples. Results Enhanced expression of clusterin (CLU), α1-antitrypsin, haptoglobin and leucine rich glycoprotein was detected in all patients. However, the levels of α1-antichymotrypsin (ACT) was only enhanced in EOCa patients, while patients with GOCa were typically characterized by elevated levels of ceruloplasmin but lower levels of α2-HS glycoprotein. The enhanced expression of CLU in EOCa and GOCa patients and up-regulated expression of ACT specifically in EOCa patients were confirmed by ELISA. Immunohistochemical staining of biopsy samples of EOCa and GOCa patients demonstrated correlation of the acute-phase protein expression. Conclusion Patients with EOCa and GOCa demonstrated distinctive aberrant expression of serum and tissue high abundance acute-phase proteins compared to negative control women.

Abstract
Broad-spectrum matrix metalloproteinase (MMP) inhibitors (MMPI) were unsuccessful in cancer clinical trials, partly due to side effects resulting from limited knowledge of the full repertoire of MMP substrates, termed the substrate degradome, and hence the in vivo functions of MMPs. To gain further insight into the degradome of MMP-14 (membrane type 1 MMP) an MMPI, prinomastat (drug code AG3340), was used to reduce proteolytic processing and ectodomain shedding in human MDA-MB-231 breast cancer cells transfected with MMP-14. We report a quantitative proteomic evaluation of the targets and effects of the inhibitor in this cell-based system. Proteins in cell-conditioned medium (the secretome) and membrane fractions with levels that were modulated by the MMPI were identified by isotope-coded affinity tag (ICAT) labeling and tandem mass spectrometry. Comparisons of the expression of MMP-14 with that of a vector control resulted in increased MMP-14/vector ICAT ratios for many proteins in conditioned medium, indicating MMP-14-mediated ectodomain shedding. Following MMPI treatment, the MMPI/vehicle ICAT ratio was reversed, suggesting that MMP-14-mediated shedding of these proteins was blocked by the inhibitor. The reduction in shedding or the release of substrates from pericellular sites in the presence of the MMPI was frequently accompanied by the accumulation of the protein in the plasma membrane, as indicated by high MMPI/vehicle ICAT ratios. Considered together, this is a strong predictor of biologically relevant substrates cleaved in the cellular context that led to the identification of many undescribed MMP-14 substrates, 20 of which we validated biochemically, including DJ-1, galectin-1, Hsp90alpha, pentraxin 3, progranulin, Cyr61, peptidyl-prolyl cis-trans isomerase A, and dickkopf-1. Other proteins with altered levels, such as Kunitz-type protease inhibitor 1 and beta-2-microglobulin, were not substrates in biochemical assays, suggesting an indirect affect of the MMPI, which might be important in drug development as biomarkers or, in preclinical phases, to predict systemic drug actions and adverse side effects. Hence, this approach describes the dynamic pattern of cell membrane ectodomain shedding and its perturbation upon metalloproteinase drug treatment.

Abstract
OBJECTIVE We assessed the association of genetic variation in MMP3 and MMP9 with risk of myocardial infarction and stroke. METHODS A case-control study was conducted among members of Group Health (GH), a large-integrated health care delivery system. Case subjects with incident non-fatal myocardial infarction (n=854), ischemic stroke (n=367), and hemorrhagic stroke (n=66) were identified and validated. A matched control group was selected from among GH members without myocardial infarction or stroke (n=2696). Haplotype-tagging sets of single-nucleotide polymorphisms (SNPs) in MMP3 and MMP9 were genotyped. RESULTS MMP3 haplotype 2 was associated with reduced risk of myocardial infarction (adjusted odds ratio (OR) per copy=0.80, 95% confidence interval 0.66, 0.98) and increased risk of hemorrhagic stroke (OR=1.69, 95% confidence interval 1.05, 2.75). Results for MMP3 haplotype 2 and ischemic stroke resembled those for myocardial infarction but did not achieve statistical significance (OR=0.85, 95% confidence interval 0.64, 1.12). No individual SNP identified MMP3 haplotype 2, and none of the individual MMP3 SNPs were associated with myocardial infarction or stroke. MMP9 haplotypes or SNPs were not associated with myocardial infarction or stroke. CONCLUSIONS MMP3 haplotype may predict both cardiac events and stroke.

Abstract
INTRODUCTION Matrix metalloproteinases (MMPs), their tissue inhibitors (TIMPs) system, and fibrinolytic system, have been implicated as important factors in atherosclerosis and vascular remodeling. However, no data are yet available on the associations between these two systems in relation to carotid atherosclerosis in hemodialysis (HD) patients. MATERIAL AND METHODS We compared plasma levels of MMP-2, MMP-9, TIMP-1, TIMP-2; the parameters of fibrinolytic system: tissue-type plasminogen activator (tPA), urokinase-type plasminogen activator (uPAR) and its soluble receptor (suPAR), plasminogen activator inhibitor-1 (PAI-1), plasmin-alpha2-antiplasmin (PAP) complexes; high sensitivity C-reactive protein (hs CRP) as a marker of inflammation and a surrogate of atherosclerotic disease-intima media thickness (IMT) in HD patients and in healthy controls. RESULTS The values of the uPA, suPAR, PAP, MMP-2, TIMPs, hs CRP and IMT in the patients significantly exceeded those in controls. The concentrations of MMP-9, tPA and PAI-1 were similar in both investigated groups. uPA, uPAR and PAP were positively associated with MMP-2/TIMPs system; all mentioned above parameters (except TIMP-2) and hsCRP were associated with IMT. Multivariate analysis showed that uPA, MMP-2 and age were the strong independent variables linked to IMT values in HD patients. CONCLUSIONS The patients on haemodialysis treatment have evidence of disordered fibrinolysis/proteolysis balance in the plasma, independently associated with IMT on multivariate analysis. These data suggest the importance of uPA and MMP-2 levels in the developing of atherosclerosis in these patients.

Abstract
Enzymes in the matrix metalloproteinase (MMP) family have been linked to key events in developmental biology for almost 50 years. Biochemical, cellular and in vivo analyses have established that pericellular proteolysis contributes to numerous aspects of ontogeny including ovulation, fertilization, implantation, cellular migration, tissue remodeling and repair. Surface anchoring of proteinase activity provides spatial restrictions on substrate targeting. This review will utilize membrane type 1 MMP (MT1-MMP) as an example to highlight substrate diversity in pericellular proteolysis catalyzed by a membrane anchored MMP.

Abstract
The proteolytic processing of bovine fibrinogen by MMP-2 (gelatinase A), which brings about the formation of a product unable to form fibrin clots, has been studied at 37 degrees C. Catalytic parameters, although showing a somewhat lower catalytic efficiency with respect to thrombin and plasmin, indeed display values indicating a pathophysiological significance of this process. A parallel molecular modelling study predicts preferential binding of MMP-2 to the beta-chain of fibrinogen through its haemopexin-like domain, which has been directly demonstrated by the inhibitory effect in the presence of the exogenous haemopexin-like domain. However, the removal of this domain does not impair the interaction between MMP-2 and fibrinogen, but it dramatically alters the proteolytic mechanism, producing different fragmentation intermediates. The investigation at various pH values between 6.0 and 9.3 indicates a proton-linked behaviour, which is relevant for interpreting the influence on the process by environmental conditions occurring at the site of an injury. Furthermore, the action of MMP-2 on peroxynitrite-treated fibrinogen has been investigated, a situation possibly occurring under oxidative stress. The chemical alteration of fibrinogen, which has been shown to abolish its clotting activity, brings about only limited modifications of the catalytic parameters without altering the main enzymatic mechanism.

Abstract
The heme-binding hemopexin consists of two, four-bladed propeller domains connected by a linker region. Hemopexin domains are found in different species on the phylogenetic tree and in the human species represented in hemopexin, matrix metalloproteinases (MMPs), vitronectin, and products of the proteoglycan 4 gene. Hemopexin and hemopexin domains of human proteins fulfill functions in activation of MMPs, inhibition of MMPs, dimerization, binding of substrates or ligands, cleavage of substrates, and endocytosis by low-density lipoprotein receptor-related protein-1 (LRP-1; CD91) and LRP-2 (megalin, GP330). Insights into the structures and functions of hemopexin (domains) form the basis for positive or negative interference with the formation of molecular complexes and hence, might be exploited therapeutically in inflammation, cancer, and wound healing.

Abstract
BACKGROUND Several experimental studies have shown the importance of arginine in wound healing. However, little is known about its role in human wound healing. In this study, we investigated arginine metabolism in impaired wound healing. MATERIALS AND METHODS Twenty patients with chronic wounds and 10 patients with acute wounds were included in a prospective study. Amino acids, nitrate/nitrite, and arginase concentrations were determined in plasma and wound fluid using high-performance liquid chromatography and enzyme-linked immunosorbent assay. Chronic wounds were divided into two groups: noninfected chronic wounds (n = 11) and infected chronic wounds (n = 9), based on quantitative bacterial analysis of wound fluid samples. RESULTS Plasma arginine levels, next to total plasma amino acid levels, were significantly decreased in patients with infected chronic wounds compared with patients having acute or noninfected wounds. Citrulline and ornithine levels were significantly increased in infected chronic wounds and related to decreased nitrate/nitrite levels, whereas wound fluid arginine levels were similar in all groups. In addition, wound fluid arginase levels of infected chronic wounds were significantly enhanced. CONCLUSIONS This study demonstrates that patients with infected chronic wounds have decreased plasma arginine levels and suggests enhanced arginine conversion in the wound. In contrast to noninfected chronic wounds, arginine seems to be mainly metabolized by arginase in infected chronic wounds. In conclusion, our hypothesis is that impaired wound healing is related to an altered arginine usage.

Abstract
Simultaneous ablation of the two known activators of plasminogen (Plg), urokinase-type (uPA) and the tissue-type (tPA), results in a substantial delay in skin wound healing. However, wound closure and epidermal re-epithelialization are significantly less impaired in uPA;tPA double-deficient mice than in Plg-deficient mice. Skin wounds in uPA;tPA-deficient mice treated with the broad-spectrum matrix metalloproteinase (MMP) inhibitor galardin (N-[(2R)-2-(hydroxamido-carbonylmethyl)-4-methylpentanoyl]-L-tryptophan methylamide) eventually heal, whereas skin wounds in galardin-treated Plg-deficient mice do not heal. Furthermore, plasmin is biochemically detectable in wound extracts from uPA;tPA double-deficient mice. In vivo administration of a plasma kallikrein (pKal)-selective form of the serine protease inhibitor ecotin exacerbates the healing impairment of uPA;tPA double-deficient wounds to a degree indistinguishable from that observed in Plg-deficient mice, and completely blocks the activity of pKal, but not uPA and tPA in wound extracts. These findings demonstrate that an additional plasminogen activator provides sufficient plasmin activity to sustain the healing process albeit at decreased speed in the absence of uPA, tPA and galardin-sensitive MMPs and suggest that pKal plays a role in plasmin generation.

Abstract
PIII snake venom metalloproteases (SVMPs) are structurally related to ADAMs (a disintegrin and metalloprotease human family of proteins). Berythractivase and Jararhagin are PIII SVMPs with 69% homology with different hemostatic properties. In order to clarify these differences and further characterize the biological effects of these proteins, we compared the effect of both proteases on human umbilical vein endothelial cell (HUVEC) for evaluating the release and modulation of coagulation and fibrinolysis mechanisms as well as the expression of their correlated genes. We found that both proteins increase the von Willebrand factor liberation, but did not modulate gene expression. Berythractivase, differently from Jararhagin increased the expression of tissue factor. Our results showed that both SVMPs (Berythractivase and Jararhagin) activate HUVEC releasing or modulating mediators involved in hemostasis. Meanwhile, we can suggest through the up-regulation of TF gene that the studied SVMP acts in a specific manner, suggesting that Jararhagin has preferentially a local action, while Berythractivase can be assumed as a systemic pro-coagulant protein with activity on the surface of HUVECs.

Abstract
In an animal model of drug idiosyncrasy, rats cotreated with nonhepatotoxic doses of lipopolysaccharide (LPS) and ranitidine (RAN) develop hepatocellular injury, whereas rats treated with LPS and famotidine (FAM) do not. The coagulation system and neutrophils (PMNs) are requisite mediators of LPS/RAN-induced liver injury. We tested the hypothesis that unique gene expression in LPS/RAN-treated rats requires coagulation system activation and that these changes are absent in rats given LPS and FAM. Rats were treated with a nonhepatotoxic dose of LPS (44.4 x 10(6) endotoxin units/kg i.v.) or its vehicle, and then 1 h later, they were treated with heparin (3000 U/kg) or its vehicle. One hour thereafter, they were given RAN (30 mg/kg), FAM (6 mg/kg, a pharmacologically equiefficacious dose, or 28.8 mg/kg, an equimolar dose), or vehicle (i.v.). They were killed 2 or 6 h after drug treatment for evaluation of hepatotoxicity, coagulation system activation, and liver gene expression (2 h only). Statistical filtering of gene array results and real-time polymerase chain reaction identified groups of genes expressed in LPS/RAN-treated rats but not LPS/FAM-treated rats that were either changed or unchanged by heparin administration. For example, LPS/RAN-induced mRNA expression of the inflammatory mediators interleukin-6, cyclooxygenase-2, and macrophage inflammatory protein-2 (MIP-2) was reduced by anticoagulation. Enhancement of serum MIP-2 and plasminogen activator inhibitor-1 concentrations in LPS/RAN-treated rats was prevented by anticoagulation. The results suggest cross-talk between hemostasis-induced gene expression and inflammation (e.g., PMN function) in the genesis of hepatocellular injury in LPS/RAN-treated rats. In contrast, neither the expression of such genes nor hepatocellular necrosis occurred in rats treated with LPS/FAM.

Abstract
The matrix metalloproteinases(MMP)-2 and -9, also known as the gelatinases have been long recognized as major contributors to the proteolytic degradation of extracellular matrix during tumor invasion. In the recent years, a plethora of non-matrix proteins have also been identified as gelatinase substrates thus significantly broadening our understanding of these enzymes as proteolytic executors and regulators in various physiological and pathological states including embryonic growth and development, angiogenesis and tumor progression, inflammation, infective diseases, degenerative diseases of the brain and vascular diseases. Although the effect of broad-spectrum inhibitors of MMPs in the treatment of cancer has been disappointing in clinical trials, novel mechanisms of gelatinase inhibition have been now identified. Inhibition of the association of the gelatinases with cell-surface integrins appears to offer highly specific means to target these enzymes without inhibiting their catalytic activity in multiple cell types including endothelial cells, tumor cells and leukocytes. Here, we review the multiple functions of the gelatinases in cancer, and especially their role in the tumor cell migration and invasion.

Abstract
During initial stages of wound healing, fibrin clots provide a three-dimensional scaffold that induces cell infiltration and regeneration. Here, L1Ig6, a ligand for alphavbeta3 integrin was covalently incorporated within fibrin matrices to explore it as a matrix-immobilized angiogenic factor. Incorporation at concentrations greater than 1 microg/ml reduced the fibrin crosslink density, as reflected by measurements of elastic modulus and swelling. The influence of crosslink density on endothelial cell process extension was characterized by modulating factor XIII concentrations in the coagulation mixture. At low incorporated concentrations of L1Ig6, it was possible to compensate gel elastic modulus via increased factor XIII, but not at high concentrations of L1Ig6. Similar findings were found when matrix swelling was analyzed. Fibrin crosslink density strongly influenced endothelial cell process extension, fewer and shorter processes were observed at high crosslink density. Matrix metalloproteinases (MMPs) were required for process extension and zymography and Western blots identified MMP-2 but not MMP-9. The amount of active MMP-2 increased for endothelial cells cultured in native and L1Ig6-modified matrices or when stimulated with VEGF-A165. The data indicate that distinct matrix properties can be tailored such that they become biologically stimulating and respond to cellular proteolytic activities, being a prerequisite for potential use of such matrices in biomedical applications.

Abstract
The deposition of the insoluble protein matrix, fibrin is temporary. The mainly known mechanism of proteolytic removal is orchestrated by a cascade type of proteolytic process involving ultimately the formation from plasminogen of the active degradation enzyme plasmin. The occurrence of plasminogen deficiency without a massive deposition of fibrin and thrombotic events indicates the occurrence of alternate routes of fibrin degradation. In the literature, data have been reported about the direct fibrinolytic activity of various other enzymes including leucocytal elastase and cathepsin G and three metalloproteinases (MMP-3,MMP-7, MT1-MMP). The importance of each of these pathways and the possible differences in importance in various diseases, in acute situations and at different locations in the circulation, in tissues and organs is not known in detail. It is suggested that multiple combined knock-outs be created to evaluate the situation for various well-defined phenotypes. It is concluded that fibrin removal is an important biological process with various buffering mechanisms and only combinations of abnormalities in the various mechanisms and special situations will lead to fibrin accumulation and thrombotic events.

Abstract
The deposition of fibrin clots in vivo occurs after injury in the peripheral nervous system and their removal correlates with nerve regeneration. Fibrin clots provide a provisional matrix for invading cells, induce wound healing, and become proteolytically removed by regenerating tissue. Here, neurite extension and in vitro myelination were studied within three-dimensional fibrin matrices that were covalently modified with the sixth Ig-like domain of cell adhesion molecules L1 containing N-terminal transglutaminase substrate sequences (TG-L1Ig6) for covalent incorporation into fibrin matrices. TG-L1Ig6 is a specific receptor for alphavbeta3-integrin involved in neurite extension of PC12 cells and dorsal root ganglion neurons (DRGs). Neurite extension of PC12 cells depended on interactions between cell surface alphavbeta3 and RGD-sites provided by TG-L1Ig6. In addition, matrix properties such as fibrin crosslink density and matrix degradation by serine proteases were crucial. No involvement of matrix metalloproteinases was found. DRG neurite extension in native fibrin matrices was retarded as compared to neurite extension within L1Ig6-modified and laminin-1-containing matrices. Moreover, myelinated structures were almost exclusively found in TG-L1Ig6-modified and laminin-1-containing matrices. These results indicate that potential use of three-dimensional matrices in a biomaterials-based healing device to induce and/or help in vivo nerve regeneration requires specific structural and biological signals.

Abstract
Coadministration of nonhepatotoxic doses of the histamine 2-receptor antagonist ranitidine (RAN) and bacterial lipopolysaccharide (LPS) results in hepatocellular injury in rats, the onset of which occurs in 3 to 6 hours. This reaction resembles RAN idiosyncratic hepatotoxicity in humans. Early fibrin deposition occurs in livers of rats cotreated with LPS/RAN. Accordingly, we tested the hypothesis that the hemostatic system contributes to liver injury in LPS/RAN-treated rats. Rats were given either LPS (44.4 x 10(6) EU/kg) or its vehicle, then RAN (30 mg/kg) or its vehicle 2 hours later. They were killed 2, 3, 6, 12, or 24 hours after RAN treatment, and liver injury was estimated from serum alanine aminotransferase activity. A modest elevation in serum hyaluronic acid, which was most pronounced in LPS/RAN-cotreated rats, suggested altered sinusoidal endothelial cell function. A decrease in plasma fibrinogen and increases in thrombin-antithrombin dimers and in serum concentration of plasminogen activator inhibitor-1 occurred before the onset of liver injury. Hepatic fibrin deposition was observed in livers from LPS/RAN-cotreated rats 3 and 6 hours after RAN. Liver injury was abolished by the anticoagulant heparin and was significantly attenuated by the fibrinolytic agent streptokinase. Hypoxia, one potential consequence of sinusoidal fibrin deposition, was observed in livers of LPS/RAN-treated rats. In conclusion, the results suggest that the hemostatic system is activated after LPS/RAN cotreatment and that fibrin deposition in liver is important for the genesis of hepatic parenchymal cell injury in this model.

Abstract
Matrix metalloproteinases (MMPs) are a family of zinc-containing endopeptidases that proteolyze extracellular matrix components as well as a variety of functional proteins. Here we describe a "degradomics" method that efficiently identifies substrates of MMP-14 in a complex protein mixture, such as plasma. Plasma proteins were incubated in the presence or absence of the MMP-14 catalytic domain and displayed on two-dimensional (2-D) gels. After a comparison of the gels, we selected 40 protein spots that reproducibly showed disparities. Upon in-gel digestion, mass determination, and peptide mass fingerprinting, we identified 15 different proteins from 31 spots. These proteins included six known substrates and nine potential substrates of MMP-14. Among the latter, the purified forms of apolipoprotein A-I, apolipoprotein E, and plasma gelsolin were cleaved in vitro by MMP-14, confirming that each of them is a novel substrate of MMP-14. These results demonstrate that our method rapidly and selectively identifies MMP-14 substrates from human plasma proteins. This method would thus constitute a powerful tool for identifying the substrates of MMPs and other proteases in highly complex mixtures of proteins and would enhance our understanding of the biological roles of these enzymes.

Abstract
Both plasminogen activators and matrix metalloproteinases (MMPs) have been implicated in a variety of developmental processes in the mouse during embryo implantation and placentation. We show here that pharmacological treatment of plasminogen-deficient mice with the broad spectrum MMP inhibitor galardin leads to a high rate of embryonic lethality. Implantation sites from plasminogen-deficient galardin-treated mice at 7.5 days post coitus (dpc) showed delay in both decidualization and invasion of maternal vessels into the decidua. At 8.5 dpc, half of the embryos were runted and still at the developmental stage of a 7.5 dpc embryo. Most embryos that escaped these initial defects eventually died, probably from defective vascularization and development of the labyrinth layer of the placenta, although a direct role on embryo development cannot be ruled out. These results demonstrate that the combination of MMPs and plasminogen is essential for the proper development of the placenta. Plasminogen deficiency alone and galardin treatment alone had much less effect and there was a pronounced synergism on both placental vascularization and embryonic lethality, indicating a functional overlap between plasminogen and MMPs.

Abstract
Fibrinogen seems to contribute significantly to cell binding and recruitment into wounds besides its major role in clot formation. We describe 19- to 21-mer cell-binding (haptotactic) peptides from the C-termini of fibrinogen beta-chain (Cbeta), the extended alphaE chain, and near the C-terminal of the gamma-chain. When these peptides were covalently bound to a biologically inert matrix such as Sepharose beads (SB), they elicited beads attachment to cells, mostly of mesenchymal origin (including fibroblasts, endothelial cells, and smooth muscle cells) as well as some transformed cell lines. Based on such haptotactic activity, these peptides were termed "haptides." By contrast, peptides homologous to fibrinogen C-termini alpha- and gamma-chains elicited no such activity. The haptide Cbeta could not block the interaction of fibroblasts with antibodies directed against integrins beta(1), alpha(v), alpha(v)beta(1), alpha(v)beta(3), and alphaIIbeta(3). Moreover, GRGDS peptide could not inhibit enhanced cell binding to SB-Cbeta, as expected from an integrin-mediated process. In soluble form the haptides were accumulated in cells with nonsaturable kinetics without any toxic or proproliferative effects in concentrations up to 80 microM. These findings suggest that the conserved haptidic sequences within fibrin(ogen) can be associated with the adhesion and migration of cells into fibrin clots and may have a significant role in normal wound healing and in various pathological conditions.

Abstract
Cross-linked fibrin is deposited in tissues surrounding wounds, inflammatory sites, or tumors and serves not only as a supporting substratum for trafficking cells, but also as a structural barrier to invasion. While the plasminogen activator-plasminogen axis provides cells with a powerful fibrinolytic system, plasminogen-deleted animals use alternate proteolytic processes that allow fibrin invasion to proceed normally. Using fibroblasts recovered from wild-type or gene-deleted mice, invasion of three-dimensional fibrin gels proceeded in a matrix metalloproteinase (MMP)-dependent fashion. Consistent with earlier studies supporting a singular role for the membrane-anchored MMP, MT1-MMP, in fibrin-invasive events, fibroblasts from MT1-MMP-null mice displayed an early defect in invasion. However, MT1-MMP-deleted fibroblasts circumvented this early deficiency and exhibited compensatory fibrin-invasive activity. The MT1-MMP-independent process was sensitive to MMP inhibitors that target membrane-anchored MMPs, and further studies identified MT2-MMP and MT3-MMP, but not MT4-MMP, as alternate pro-invasive factors. Given the widespread distribution of MT1-, 2-, and 3-MMP in normal and neoplastic cells, these data identify a subset of membrane-anchored MMPs that operate in an autonomous fashion to drive fibrin-invasive activity.

Abstract
An immune and inflammatory response involving endothelial and smooth muscle cells accompanies the accumulation of lipids and fibrous materials in atheromatous arteries. The inflammatory response involves not only the intrinsic cells of the artery wall, but also circulating leukocytes. Lymphocytes as well as macrophages participate importantly in this disease process. Plaque composition and vulnerability have emerged as more critical determinants of plaque rupture than the degree of lumenal stenosis. Thus, plaque biology has proven more important than gross morphology in determining the clinical consequences of the disease. Rupture of the atherosclerotic plaque, its thrombotic complications, and their sequelae have gained increased recognition as the proximate causes of disability and death due to related syndromes such as acute myocardial infarction. Arterial thromboses occur much more readily in arteries damaged or distorted by the atherosclerotic process. The consequences of a given plaque disruption and subsequent thrombus formation will depend on both "systemic" or fluid phase determinants and local "solid state" factors. The complex heterogeneous structure of thrombi includes fibrin, platelets, erythrocytes, and leukocytes. The local balance of proteases and inhibitors on the fibrin and cell surfaces will determine thrombus stability and persistence. Enhanced understanding of the processes involved in the development and progression of atherosclerosis and its complications will surely provide areas that can be targeted in the treatment of the disease.

Abstract
Vascular integrity is maintained by a sophisticated system of circulating and cell associated hemostatic factors that control local platelet deposition, the conversion of soluble fibrinogen to an insoluble fibrin polymer, and the dissolution of fibrin matrices. However, hemostatic factors are likely to be biologically more important than merely maintaining vascular patency and controlling blood loss. Specific hemostatic factors have been associated with a wide spectrum of physiological processes, including development, reproduction, tissue remodeling, wound repair, angiogenesis, and the inflammatory response. Similarly, it has been proposed that hemostatic factors are important determinants of a variety of pathological processes, including vessel wall disease, tumor dissemination, infectious disease, and inflammatory diseases of the joint, lung, and kidney. The development of gene targeted mice either lacking or expressing modified forms of selected hemostatic factors has provided a valuable opportunity to test prevailing hypotheses regarding the biological roles of key coagulation and fibrinolytic system components in vivo. Genetic analyses of fibrin(ogen) and its interacting factors in transgenic mice have proven to be particularly illuminating, often challenging long standing concepts. This review summarizes the key findings made in recent studies of gene targeted mice with single and combined deficits in fibrinogen and fibrinolytic factors. Studies illustrating the role and interplay of these factors in disease progression are highlighted.

Abstract
Matrix metalloproteinase-3 (MMP-3 or stromelysin-1) hydrolyzes the Met(374)-Ser(375) (P3-P2), Glu(416)-Leu(417) and Ser(432)-Leu(433) peptide bonds in human alpha(2)-antiplasmin (alpha(2)-AP), the main physiological plasmin inhibitor. Cleavage is completely abolished in the presence of the MMP inhibitors EDTA or 1,10-phenanthroline. At enzyme/substrate ratio of 1:10 at 37 degrees C, alpha(2)-AP protein cleavage occurs with a half-life of 8 min, and is associated with rapid loss of inhibitory activity towards plasmin with a half-life of 5 min. alpha(2)-AP cleaved by MMP-3 does no longer form a stable complex with plasmin, as shown by SDS-PAGE, and does no longer interact with plasminogen, as shown by crossed immunoelectrophoresis with plasminogen added to the gel. These data are compatible with the removal of a COOH-terminal fragment containing the reactive site peptide bond and the plasmin(ogen)-binding site. In addition, MMP-3 cleaves the Pro(19)-Leu(20) peptide bond in alpha(2)-AP, thereby removing the fibrin-binding site from the inhibitor. A dysfunctional alpha(2)-AP variant (Ala-alpha(2)-AP or alpha(2)-AP Enschede), with an alanine insertion in the reactive site sequence converting it from a plasmin inhibitor into a substrate, was also efficiently cleaved by MMP-3 (half-life of 13 min at 37 degrees C and enzyme/substrate ratio of 1:10). Cleavage and inactivation of alpha(2)-AP by MMP-3 may constitute a mechanism favoring local plasmin-mediated proteolysis.

Abstract
Many human thrombi lyse spontaneously without the administration of lytic drugs and cause no clinical symptoms. The mechanisms by which this occurs are incompletely understood. We found that model thrombi prepared from whole human blood in a Chandler loop also exhibited significant spontaneous lysis. Lysis was inhibited by chemical protease inhibitors, consistent with proteolysis resulting primarily from serine proteases, with a small contribution from matrix metalloproteinases. Whole blood was fractionated into platelet-rich plasma and cell populations. Significant spontaneous lysis was observed in platelet-rich thrombi enriched with polymorphonuclear leucocytes (PMNs), whereas mononuclear cells (MCs) and erythrocytes did not contribute to lysis. Incorporation of antibodies to urokinase (u-PA) and its receptor u-PAR neutralized a large proportion of the activity. Incubation of plasma with PMNs generated free u-PA activity, which was also detectable in model thrombi and in vivo human thrombi. Purified neutrophils, free of eosinophils, generated activity identical to PMNs. Smaller contributions to lysis by tissue-type plasminogen activator (t-PA), elastase and cathepsin G were also identified. These findings suggest a major role for circulating PMNs in endogenous thrombus lysis.

Abstract
To test the hypothesis that Glu202, adjacent to the His201 residue that participates in the coordination of Zn(2+) in matrix metalloproteinase-3 (MMP-3 or stromelysin-1), plays a role in its enzymatic activity it was substituted with Ala, Lys or Asp by site-specific mutagenesis. Wild-type proMMP-3, proMMP-3(E202A), proMMP-3(E202K) and proMMP-3(E202D) were expressed in Escherichia coli and purified to apparent homogeneity. Whereas 33-kDa wild-type proMMP-3 (consisting of the propeptide and catalytic domains) was quantitatively converted to 24-kDa active MMP-3 by treatment with p-aminophenyl-mercuric acetate (APMA), proMMP-3(E202A) and proMMP-3 (E202K) were fully resistant to APMA and proMMP-3 (E202D) was quantitatively converted into a 14-kDa species. In contrast, treatment with plasmin quantitatively converted the wild-type and the three mutant proMMP-3 moieties into the corresponding 24-kDa MMP-3 moieties. Biospecific interaction analysis revealed comparable affinity for binding to plasminogen of wild-type and mutant proMMP-3 (K(a) of 2.6-6.3 x 10(6) M(-1)) or MMP-3 (K(a) of 33-58 x 10(6) M(-1)) moieties. The affinity for binding to single-chain urokinase-type plasminogen activator (scu-PA) was also similar for wild-type and mutant proMMP-3 (K(a) of 5.0-6.9 x 10(6) M(-1)) or MMP-3 (K(a) of 37-72 x 10(6) M(-1)) moieties. However, MMP-3(E202A) and MMP-3(E202K) did not hydrolyze plasminogen whereas MMP-3(E202D) showed an activity of 20--30% of wild-type MMP-3. All three mutants were inactive towards scu-PA under conditions where this was quantitatively cleaved by wild-type MMP-3. Furthermore, MMP-3(E202A) and MMP-3(E202K) were inactive toward a fluorogenic substrate and MMP-3 (E202D) displayed about 15% of the activity of wild-type MMP-3. Taken together, these data suggest that Glu202 plays a crucial role in the enzymatic activity of MMP-3.

Abstract
Matrix metalloproteinase-3 (MMP-3 or stromelysin-1) specifically hydrolyzes the Ser(337)-Ser(338) (P10-P9) and Val(341)-Ile(342) (P6-P5) peptide bonds in human plasminogen activator inhibitor-1 (PAI-1). Cleavage is completely abolished in the presence of the metal chelators EDTA or 1,10-phenanthroline. A stabilized active PAI-1 variant was also cleaved by MMP-3. At an enzyme/substrate ratio of 1/10 at 37 degrees C, PAI-1 protein cleavage occurred with half-lives of 27 or 14 min for active or stable PAI-1 and was associated with rapid loss of inhibitory activity toward tissue-type plasminogen activator with half-lives of 15 or 13 min, respectively. A substrate-like variant of PAI-1, lacking inhibitory activity but with exposed reactive site loop, was cleaved with a half-life of 23 min, whereas latent PAI-1 in which a major part of the reactive site loop is inserted into the molecule, was resistant to cleavage. Biospecific interaction analysis indicated comparable binding of active, stable, and substrate PAI-1 to both proMMP-3 and MMP-3 (K(A) of 12-22 x 10(6) m(-1)), whereas binding of latent PAI-1 occurred with lower affinity (1.7-2.3 x 10(6) m(-1)). Stable PAI-1 bound to vitronectin was cleaved and inactivated by MMP-3 in a manner comparable with that of free PAI-1; however, the cleaved protein did not bind to vitronectin. Cleavage and inactivation of PAI-1 by MMP-3 may thus constitute a mechanism decreasing the antiproteolytic activity of PAI-1 and impairing the potential inhibitory effect of vitronectin-bound PAI-1 on cell adhesion and/or migration.
