Abstract
A bidirectional association exists between metastatic dissemination and the hypercoagulable state associated with many types of cancer. As such, clinical studies have provided evidence that markers associated with elevated levels of coagulation and fibrinolysis correlate with decreased patient survival. However, elucidating the mechanisms underpinning the effects of different components of the coagulation system on metastasis formation is challenging both in animal models and 2D models lacking the complex cellular interactions necessary to model both thrombosis and metastasis. Here, an in vitro, 3D, microvascular model for observing the formation of fibrin thrombi is described, which is in turn used to study how different aspects of the hypercoagulable state associated with cancer affect the endothelium. Using this platform, cancer cells expressing ICAM-1 are shown to form a fibrinogen-dependent bridge and transmigrate through the endothelium more effectively. Cancer cells are also demonstrated to interact with fibrin thrombi, using them to adhere, spread, and enhance their extravasation efficiency. Finally, thrombin is also shown to enhance cancer cell extravasation. This system presents a physiologically relevant model of fibrin clot formation in the human microvasculature, enabling in-depth investigation of the cellular interactions between cancer cells and the coagulation system affecting cancer cell extravasation.

Abstract
BACKGROUND COVID-19 is associated with a dysregulated immune response but it is unclear how immune dysfunction contributes to the chronic morbidity persisting in many COVID-19 patients during convalescence (long COVID). METHODS We assessed phenotypical and functional changes of monocytes in COVID-19 patients during hospitalisation and up to 9 months of convalescence following COVID-19, respiratory syncytial virus or influenza A. Patients with progressive fibrosing interstitial lung disease were included as a positive control for severe, ongoing lung injury. RESULTS Monocyte alterations in acute COVID-19 patients included aberrant expression of leukocyte migration molecules, continuing into convalescence (n=142) and corresponding with specific symptoms of long COVID. Long COVID patients with unresolved lung injury, indicated by sustained shortness of breath and abnormal chest radiology, were defined by high monocyte expression of C-X-C motif chemokine receptor 6 (CXCR6) (p<0.0001) and adhesion molecule P-selectin glycoprotein ligand 1 (p<0.01), alongside preferential migration of monocytes towards the CXCR6 ligand C-X-C motif chemokine ligand 16 (CXCL16) (p<0.05), which is abundantly expressed in the lung. Monocyte CXCR6 and lung CXCL16 were heightened in patients with progressive fibrosing interstitial lung disease (p<0.001), confirming a role for the CXCR6-CXCL16 axis in ongoing lung injury. Conversely, monocytes from long COVID patients with ongoing fatigue exhibited a sustained reduction of the prostaglandin-generating enzyme cyclooxygenase 2 (p<0.01) and CXCR2 expression (p<0.05). These monocyte changes were not present in respiratory syncytial virus or influenza A convalescence. CONCLUSIONS Our data define unique monocyte signatures that define subgroups of long COVID patients, indicating a key role for monocyte migration in COVID-19 pathophysiology. Targeting these pathways may provide novel therapeutic opportunities in COVID-19 patients with persistent morbidity.

Squalene synthase promotes the invasion of lung cancer cells via the osteopontin/ERK pathway. Oncogenesis 2020; 9:78.

Abstract
Cholesterol is the major component of lipid rafts. Squalene synthase (SQS) is a cholesterol biosynthase that functions in cholesterol biosynthesis, modulates the formation of lipids rafts and promotes lung cancer metastasis. In this study, we investigated the lipid raft-associated pathway of SQS in lung cancer. Gene expression microarray data revealed the upregulation of secreted phosphoprotein 1 (SPP1; also known as osteopontin, OPN) in CL1-0/SQS-overexpressing cells. Knockdown of OPN in SQS-overexpressing cells inhibits their migration and invasion, whereas an OPN treatment rescues the migration and invasion of SQS knockdown cells. High OPN expression is associated with lymph node status, advanced stage and poor prognosis in patients with lung cancer. Moreover, patients with high SQS expression and high OPN expression show poor survival compared with patients with low SQS expression and low OPN expression. SQS induces the phosphorylation of Src and ERK1/2 via OPN, resulting in increased expression of MMP1 and subsequent metastasis of lung cancer cells. Based on our findings, SQS expression increases the expression of OPN and phosphorylation of Src through cholesterol synthesis to modulate the formation of lipid rafts. SQS may represent a therapeutic strategy for lung cancer.

Abstract
Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases responsible for tissue remodeling and degradation of extracellular matrix (ECM) proteins. MMPs may modulate various cellular and signaling pathways in atherosclerosis responsible for progression and rupture of atherosclerotic plaques. The effect of MMPs polymorphisms and the expression of MMPs in both the atherosclerotic plaque and plasma was shown. They are independent predictors of atherosclerotic plaque instability in stable coronary heart disease (CHD) patients. Increased levels of MMPs in patients with advanced cardiovascular disease (CAD) and acute coronary syndrome (ACS) was associated with future risk of cardiovascular events. These data confirm that MMPs may be biomarkers in plaque instability as they target in potential drug therapies for atherosclerosis. They provide important prognostic information, independent of traditional risk factors, and may turn out to be useful in improving risk stratification.

Abstract
BACKGROUND Cluster of differentiation 147 (CD147) is a multifunctional glycoprotein that functions as an inducer of matrix metalloproteinase (MMP) expression in fibroblasts. Synergistically enhanced MMP-2 expression was recently observed in the coculture of human gingival fibroblasts (HGFs) and U937 human monocytic cells; however, the responsible mechanisms have not yet been fully established. The aim of this study was to evaluate the release of soluble CD147 in HGFs after coculturing with U937 cells and its functional effect on the enhancement of MMP-2 expression in HGFs. METHODS Enzyme-linked immunosorbent assay was used to determine the amount of CD147 protein in media, whereas real-time polymerase chain reaction was performed to evaluate the mRNA levels of CD147 and MMP-2 in HGFs and U937 cells. The enzyme activities of MMP-2 released from cells were examined by zymography. Transwell coculturing and conditioned media treatments were selected to rule out the effect of direct contact of HGFs and U937 cells. RESULTS The protein and mRNA expression of CD147 in HGFs were enhanced after transwell coculturing with U937 cells and exposure to U937-conditioned medium. MMP-2 enzyme activities in HGFs were also significantly increased by the coculturing methods. Administration of exogenous CD147 enhanced MMP-2 expression in HGFs, whereas treatment with cyclosporine-A, which inhibited CD147 expression, reduced U937-enhanced MMP-2 expression in HGFs. CONCLUSIONS CD147 can interact with fibroblasts to stimulate the expression of MMPs associated with periodontal extracellular matrix degradation. This study has demonstrated that CD147 released from fibroblasts might play a role in monocyte-enhanced MMP-2 expression in HGFs.

Abstract
The adhesion of monocytes to endothelial cells is one of the early stages in the development of atherosclerosis. The expression of type IV collagenases, which include matrix metalloproteinase (MMP)-2 and MMP-9, in monocytes is hypothesized to play an important role in monocyte infiltration and transformation into foam cells. The aim of the present study was to examine the effects of monocyte-endothelium interactions on the expression levels of type IV collagenases and their specific inhibitors in monocytes, and to investigate the roles of tumor necrosis factor (TNF)-α and interleukin (IL)-1β in this process. Monocytes were single-cultured or co-cultured with endothelial cells. The expression of the type IV collagenases, MMP-2 and MMP-9, and their specific inhibitors, tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2, in monocytes was determined by immunohistochemistry followed by image analysis. The expression levels of MMP-2 and MMP-9 were found to be low in the single-culture monocytes, but increased significantly when the monocytes and endothelial cells were co-cultured. However, treatment with monoclonal TNF-α or IL-1β antibodies partially inhibited the upregulated expression of MMP-2 and MMP-9 in the co-cultured monocytes. Expression of TIMP-1 and TIMP-2 was observed in the single monocyte culture, and a small increase in the expression levels was observed when the monocytes were co-cultured with endothelial cells. Therefore, monocyte-endothlium interactions were shown to increase the expression of type IV collagenases in monocytes, resulting in the loss of balance between MMP-2 and -9 with TIMP-1 and -2. In addition, TNF-α and IL-1β were demonstrated to play important roles in this process.

Abstract
Matrix metalloproteinases (MMP) are a family of zinc-containing endoproteinases that degrade extracellular matrix (ECM) components. MMP have important roles in the development, physiology and pathology of cardiovascular system. Metalloproteases also play key roles in adverse cardiovascular remodeling, atherosclerotic plaque formation and plaque instability, vascular smooth muscle cell (SMC) migration and restenosis that lead to coronary artery disease (CAD), and progressive heart failure. The study of MMP in developing animal model cardiovascular systems has been helpful in deciphering numerous pathologic conditions in humans. Increased peripheral blood MMP-2 and MMP-9 in acute coronary syndrome (ACS) may be useful as noninvasive tests for detection of plaque vulnerability. MMP function can be modulated by certain pharmacological drugs that can be exploited for treatment of ACS. CAD is a polygenic disease and hundreds of genes contribute toward its predisposition. A large number of sequence variations in MMP genes have been identified. Case-control association studies have highlighted their potential association with CAD and its clinical manifestations. Although results thus far are inconsistent, meta-analysis has demonstrated that MMP-3 Glu45Lys and MMP-9 1562C/T gene polymorphisms were associated with CAD risk.

Abstract
Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that primarily degrade components of the extracellular matrix (ECM). Remodeling of the ECM by MMPs is important in both physiological and pathological processes, including organ generation/regeneration, angiogenesis, wound healing, inflammation and tumor growth. In the vasculature, MMPs play a role in beneficial processes such as angiogenesis, collateral artery formation and thrombus resolution. However, MMP expression is also implicated in the pathogenesis of vascular diseases such as atherosclerosis, aortic aneurysms, plaque rupture and neointimal hyperplasia after balloon angioplasty. Here, we review the structure, functions and roles of MMPs in both neovascularization and vascular pathology and discuss the potential of, and challenges that face, adapting MMPs as therapeutic targets in vascular disease.

Abstract
Monocyte-endothelial interactions play an important role in inflammatory diseases and may modulate vasculopathy in sickle cell disease, a disorder with an important inflammatory component. We co-incubated normal and sickle monocytes, lymphocytes and TNF-α with pulmonary microvascular and arterial endothelial cells and compared the expression of genes coding for adhesion molecules and cytokines that might contribute to sickle vasoocclusion. Monocyte-endothelial cell co-incubation resulted in up-regulation of L-selectin, E-selectin, VCAM-1, ICAM-1, MCP-1, MMP-1, TNF-α, IL-6 and IL-1β and down-regulation of eNOS. Lymphocyte-endothelial cell co-incubations, induced similar effects restricted to pulmonary artery endothelial cells. TNF-α had similar effects on the endothelial cells as monocytes did, however monocyte induced gene expression in endothelial cells was not TNF-α dependent but was regulated through the NF-κB pathway. Sickle monocytes lead to altered expression of L-selectin, MCP-1 and MMP-1 in pulmonary vascular endothelium when compared with normal monocytes. The gene expression changes we observed could reflect pathological events of sickle vasoocclusion.

Abstract
Inflammation is a central element of atherogenesis. Innate pathways contribute to vascular inflammation. However, the initial molecular process(es) starting atherogenesis remain elusive. The various risk factors, represented by particular compounds (activators), may cause altered cellular functions in the endothelium (e.g. vascular endothelial cell activation or -dysfunction), in invading cells (e.g. inflammatory mediator production) or in local vessel wall cells (e.g. inflammatory mediators, migration), thereby triggering the innate inflammatory process. The cellular components of innate immunology include granulocytes, natural killer cells and monocytes. Among the molecular innate constituents are innate molecules, such as the toll-like receptors or innate cytokines. Interleukin-1 (IL-1) and IL-6 are among the innate cytokines. Cytokines are potent activators of a great number of cellular functions relevant to maintain or commove homeostasis of the vessel wall. Within the vessel wall, vascular smooth muscle cells (SMCs) can significantly contribute to the cytokine-dependent inflammatory network by: (i) production of cytokines, (ii) response to cytokines and (iii) cytokine-mediated interaction with invading leucocytes. The cytokines IL-1 and IL-6 are involved in SMC-leucocyte interaction. The IL-6 effects are proposed to be mediated by trans-signalling. Dysregulated cellular functions resulting from dysregulated cytokine production may be the cause of cell accumulation, subsequent low-density lipoprotein accumulation and deposition of extracellular matrix (ECM). The deposition of ECM, increased accumulation of leucocytes and altered levels of inflammatory mediators may constitute an 'innate-immunovascular-memory' resulting in an ever-growing response to anew invasion. Thus, SMC-fostered inflammation, promoted by invading innate cells, may be a potent component for development and acceleration of atherosclerosis.

Abstract
Cardiovascular diseases are the human diseases with the highest death rate and atherosclerosis is one of the major underlying causes of cardiovascular diseases. Inflammatory and innate immune mechanisms, employing monocytes, innate receptors, innate cytokines, or chemokines are suggested to be involved in atherogenesis. Among the inflammatory pathways the cytokines are central players. Plasma levels of cytokines and related proteins, such as CRP, have been investigated in cardiovascular patients, tissue mRNA expression was analyzed and correlations to vascular diseases established. Consistent with these findings the generation of cytokine-deficient animals has provided direct evidence for a role of cytokines in atherosclerosis. In vitro cell culture experiments further support the suggestion that cytokines and other innate mechanisms contribute to atherogenesis. Among the initiation pathways of atherogenesis are innate mechanisms, such as toll-like-receptors (TLRs), including the endotoxin receptor TLR4. On the other hand, innate cytokines, such as IL-1 or TNF, or even autoimmune triggers may activate the cells. Cytokines potently activate multiple functions relevant to maintain or spoil homeostasis within the vessel wall. Vascular cells, not least smooth muscle cells, can actively contribute to the inflammatory cytokine-dependent network in the blood vessel wall by: (i) production of cytokines; (ii) response to these potent cell activators; and (iii) cytokine-mediated interaction with invading cells, such as monocytes, T-cells, or mast cells. Activation of these pathways results in accumulation of cells and increased LDL- and ECM-deposition which may serve as an 'immunovascular memory' resulting in an ever-growing response to subsequent invasions. Thus, vascular cells may potently contribute to the inflammatory pathways involved in development and acceleration of atherosclerosis.

Abstract
AIMS To investigate whether patients with acute coronary syndrome (ACS) possessed high levels of platelet-monocyte aggregates (PMAs) and related circulating biomarkers. METHODS 74 ACS patients, 58 stable angina pectoris (SAP) patients and 46 control patients without coronary artery disease were selected and their PMAs were measured by flow cytometry. Their plasma IL-6, IL-8, MCP-1, soluble CD40L and soluble P-selectin were also measured simultaneously by flow cytometry. RESULTS Patients with ACS exhibited higher level of PMAs compared with SAP patients and the control. Furthermore, the levels of IL-6, IL-8, MCP-1, soluble CD40L, soluble P-selectin and CRP were also significantly higher in ACS patients than in SAP patients and the control group. However, there were no significant difference in the levels of IL-8, sCD40L, sP-selectin and CRP between SAP patients and the control group. Correlation analysis showed that high levels of IL-6 and sP-selectin were significantly correlated with PMAs. Logistic analysis further demonstrated that the presence of elevated CRP, IL-6 and PMAs level each confers an increased risk of ACS. CONCLUSION Elevated levels of PMAs and related circulating biomarkers might indicate the unstable coronary syndrome in ACS patients, and the levels of PMAs, CRP and IL-6 could be used for monitoring and guiding the early intervention of ACS patients.

Abstract
BACKGROUND It has been postulated that systemic infection with pathogens such as Porphyromonas gingivalis (Pg) elevates the inflammatory response and increases susceptibility to atherosclerosis. We hypothesized that Doxycycline would be beneficial in diet- and/or Pg-induced atherosclerosis given its role in various cell functions and matrix remodeling. METHODS AND RESULTS ApoE+/- mice were inoculated weekly with Pg and treated with either Doxycycline or saline; animals were fed either a high-fat or chow diet. Animals were euthanized at 14 or 24 weeks and histomorphometric analysis of atheromatous lesions in proximal aorta, levels of SAA and serum cytokine profiling were performed. Histomorphometric analysis demonstrated that in non-infected mice fed a high fat diet, Doxycycline treatment resulted in a reduction of mean lesions from 10.5%+/-.49 to 1.09%+/-0.102 (p<0.05) at 14 weeks and a reduction from 21.5%+/-6.49 to 8.26%+/-0.162 (p=0.106) at 24 weeks. Chow-fed Pg mice treated with Doxyclycline also resulted in a reduction from 0.62%+/-0.128 to 0.0%+/-0.0 (p<0.05) at 14 weeks and a reduction from 0.92%+/-0.23 to 0.0%+/-0.0 (p<0.05) at 24 weeks. Administration of Doxycycline to mice fed a high fat diet and Pg-inoculated resulted in a reduction of mean percentage of atheromatous lesions from 16.46%+/-1.69 to 1.141%+/-0.23 (p<0.05) at 14 weeks and a reduction from 25.27%+/-1.734 to 0.428%+/-0.033 (p<0.05) at 24 weeks. At this timepoint, SAA levels in Pg-infected animals were reduced by five-fold and three-fold in Doxycycline-treated chow and high fat-diet groups, respectively. Cytokine antibody arrays revealed a marked reduction in the levels of pro-inflammatory cytokines in Doxycycline-treated groups whether Pg-infected or fed a high fat diet while anti-inflammatory cytokines were not affected. Consistent with the role of Doxycycline on matrix proteases, at 24 weeks MMP-9 Serum levels were markedly reduced by 60% (p<0.05) and 30% (p<0.05) with Doxycycline treatment in Pg-infected high fat and chow diet groups, respectively. CONCLUSIONS Doxycycline decreases pro-inflammatory cytokines and results in reduction of atherosclerosis in ApoE+/-Pg-inoculated and/or high fat diet fed mice.

Abstract
Smoking causes up to 11% of total global cardiovascular deaths. Smoking has numerous effects that may promote atherosclerosis through vascular inflammation and oxidative stress, but the pathogenesis of smoking-related cardiovascular disease remains incompletely understood. The matrix metalloproteinases, a family of endopeptidases that can degrade extracellular matrix components in both physiological and pathophysiological states, play an important role in smoking-associated chronic obstructive pulmonary disease, the second leading cause of smoking attributable mortality. Emerging evidence indicates that the matrix metalloproteinases may also contribute to smoking-related vascular disease. Here we discuss the potential relationship between smoking, matrix metalloproteinases, and acceleration of vascular disease.

Abstract
Adhesion, migration and invasion of endothelial cells are prerequisites for the formation of blood vessels and have to be controlled on a subcellular level. We report that subconfluent human umbilical vein endothelial cells (HUVEC) are able to constitutively form podosomal adhesions that are sites of matrix metalloprotease concentration and matrix degradation. Importantly, incubation of serum-starved cells with VEGF or TNFalpha revealed the dependence of podosomes on cytokine signaling. Podosome formation was also stimulated by addition of monocytes to HUVEC. Microinjection/application of specific inhibitors or active/inactive mutants showed that regulatory pathways include Src kinase and RhoGTPase signaling, N-WASP activation and Arp2/3 complex-dependent actin nucleation. In sum, our data show that HUVEC displaying a migratory phenotype constitutively form f-actin-rich adhesions with podosomal characteristics downstream of cytokine signaling. We propose that HUVEC podosomes play an important role in endothelial cell migration and invasion.

Abstract
Intimal thickening, the accumulation of cells and extracellular matrix within the inner vessel wall, is a physiological response to mechanical injury, increased wall stress, or chemical insult (e.g., atherosclerosis). If excessive, it can lead to the obstruction of blood flow and tissue ischemia. Together with expansive or constrictive remodeling, the extent of intimal expansion determines final lumen size and vessel wall thickness. Plaque rupture represents a failure of intimal remodeling, where the fibrous cap overlying an atheromatous core of lipid undergoes catastrophic mechanical breakdown. Plaque rupture promotes coronary thrombosis and myocardial infarction, the most prevalent cause of premature death in advanced societies. The matrix metalloproteinases (MMPs) can act together to degrade the major components of the vascular extracellular matrix. All cells present in the normal and diseased blood vessel wall upregulate and activate MMPs in a multistep fashion driven in part by soluble cytokines and cell-cell interactions. Activation of MMP proforms requires other MMPs or other classes of protease. MMP activation contributes to intimal growth and vessel wall remodeling in response to injury, most notably by promoting migration of vascular smooth muscle cells. A broader spectrum and/or higher level of MMP activation, especially associated with inflammation, could contribute to pathological matrix destruction and plaque rupture. Inhibiting the activity of specific MMPs or preventing their upregulation could ameliorate intimal thickening and prevent myocardial infarction.

Abstract
Atherosclerosis is a major cause of coronary heart disease, and matrix metalloproteinases (MMPs) play an important role in atherosclerosis by degrading the extracellular matrix, which results in cardiovascular remodeling. Recent studies have identified enhanced expression of MMPs in the atherosclerotic lesion and their contribution to weakening of the vascular wall by degrading the extracellular matrix. The transcription, enzyme processing, and specific inhibition of MMPs by tissue inhibitors of matrix metalloproteinase (TIMPs) regulate these effects. These processes are also modified by inflammatory cytokines and cell-cell contact signaling. Both animal experiments and clinical sample analysis have shown that balance in expression and activation of MMPs and inhibition by TIMPs is critical for the development of stenotic and aneurysmal change. Polymorphism in the MMP gene promoter contributes to inter-individual differences in susceptibility to coronary heart disease. The development of therapeutic drugs specifically targeting MMPs may thus be useful for the prevention of atherosclerotic lesion progression, plaque rupture, and restenosis.

Abstract
Phorbol ester triggers the conversion of focal adhesions into podosomes in A7r5 smooth muscle cells. Here we followed the dynamics of podosome formation using dual fluorescence live video and confocal microscopy, as well as interference reflection and evanescent wave microscopy. We show that podosomes form at the outer region of stress fiber bundles, at specialized sites where they are embedded in adhesion plaques at the basal surface of the plasma membrane, and that cortactin resides constitutively at these microdomains. We further demonstrate that the formation of podosomes requires Arp2/3-dependent actin polymerization at the stress fiber-focal adhesion interface. Concentration of Arp2/3 coincides with podosome formation and precedes the engagement of SM22 and alpha-actinin, while the focal adhesion components zyxin and vinculin redistribute only at later stages of podosome development. We thus suggest that the genesis of podosomes includes two steps, one requiring the early de novo polymerization of actin filaments, and a second, late phase characterized by the recruitment of focal adhesion components. Moreover, we provide evidence for the existence of an as yet unidentified region in close proximity to the focal adhesion-stress fiber interface, which marks the site of actin cytoskeleton remodeling and is a novel site of Arp2/3-dependent F-actin polymerization.

Abstract
The proteolytic activity of proinflammatory matrix metalloproteinases (MMPs) is elevated in lipid-rich atherosclerotic plaques, thereby contributing to plaque fragility and rupture. We hypothesized that changes in circulating levels of MMPs and their specific inhibitors (TIMPs) could reflect the atherosclerotic process occurring within the arterial wall. We determined serum levels of MMP-3, MMP-9, TIMP-1 and TIMP-2 in dyslipidemic subjects and compared them to those of age- and sex-matched normolipidemic healthy controls. Serum levels of MMP-3, MMP-9 and TIMP-1 were significantly increased in hyperlipidemic subjects versus controls (+54, +29 and +15%, respectively; P<0.001). We also noted a trend to elevated serum MMP-3 levels in patients with atherosclerotic lesions when compared to patients free of atherosclerosis (P=0.07). Circulating levels of MMPs and TIMPs were associated neither with those of C-reactive protein, nor with those of alpha2-macroglobulin (a nonspecific MMP inhibitor), nor with intima-media thickness values. Nonetheless, when divided into tertiles, MMP-3 and TIMP-1 levels in the highest tertile were positively associated with the presence of carotid artery lesions (odds ratios=3.4 and 2.0, confidence intervals 1.7-13.9 and 1.3-7.9, respectively). Thus, serum levels of MMP-3, -9 and TIMP-1 are significantly elevated in asymptomatic hyperlipidemic subjects at high cardiovascular risk; however, MMP-3 and TIMP-1 levels are strongly positively associated with the presence of carotid lesions. Such elevations might reflect enhanced vascular matrix remodeling, a key feature of the progression of atherosclerotic disease.

Abstract
Matrix metalloproteinases (MMPs; matrixins) are a family of structurally related enzymes that collectively promote turnover of all components of the extracellular matrix. Matrix turnover is required for vascular repair, but, if excessive, leads to pathologies that include aneurysm formation and atherosclerotic plaque instability. We review the positive and negative regulation of metalloproteinase gene induction. We propose that multiple steps of gene induction recruit a wider spectrum of MMPs, which may ultimately lead to a transition from matrix turnover to matrix destruction. Studying the detailed mechanisms involved may suggest possibilities for intervening selectively against pathological MMP induction.

Abstract
Degradation of extracellular matrix, particularly interstitial collagen, promotes plaque instability and contributes to restenosis after vascular injury. We have explored the effects of vitamins C and E on the collagen content and metalloproteinase-1 (MMP-1) expression after angioplasty in hypercholesterolemic pigs. Iliac angioplasty was performed on 18 minipigs divided into three diet groups: a normal-cholesterol (NC), a high-cholesterol (HC) and a high-cholesterol plus vitamins C+E (HCV). Four weeks later, after sacrifice, the vascular collagen content and MMP-1 protein expression, along with the plasma caseinolytic activity and lipid peroxidation, were measured. MMP-1 was also determined in arterial rings stimulated with native low-density lipoproteins (LDL) isolated from experimental groups. Cholesterol-rich diet augmented plasma lipid peroxidation (P<0.05), reduced the collagen content and increased vascular MMP-1 expression after injury (P<0.05). Enhanced caseinolytic activity (identified as MMP-1) was also observed in HC plasma samples and in supernatants from arterial rings incubated with HC-LDL. Vitamins C and E markedly increased neointimal collagen content (P<0.01), reduced the hypercholesterolemia-induced changes in vascular MMP-1 (P<0.05) and diminished plasma and ex vivo caseinolytic activity. Vitamins C and E may help stabilize atherosclerotic plaque after angioplasty and favor vascular remodeling by increasing collagen content and reducing vascular MMP-1 expression in porcine hypercholesterolemia.

Abstract
Matrix metalloproteinases (MMPs) play an important role in cardiovascular remodeling by degrading the extracellular matrix. Enhanced MMP expression has been detected in the atherosclerotic plaque, and activation of MMPs appears to be involved in the vulnerability of the plaque. Circulating MMP levels are elevated in patients with acute myocardial infarction and unstable angina. Increased MMP expression is also observed after coronary angioplasty, which is related to late loss index after the procedure. These observations suggest that MMP expression may be not only related to instability of the plaque, but also to the formation of restenotic lesions. The development of therapeutic drugs targeted specifically against MMPs may be useful in the prevention of atherosclerotic lesion development, plaque rupture, and restenosis.

Abstract
Matrix metalloproteinases (MMPs) are synthesized in response to diverse stimuli, including cytokines, growth factors, hormones, and oxidative stress. Here we show that the nitric oxide (NO) donor 2-(N,N-diethylamino)-diazenolate-2-oxide (DEA-NO) and NO from murine macrophages transcriptionally regulate MMP-13 expression in vascular endothelial cells (BAEC). The cGMP analog, 8-bromo-cGMP (8-Br-cGMP) mimicked the effect of NO, whereas incubation with the guanylate cyclase inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one, or the cGMP-dependent protein kinase (PKG) inhibitor phenyl-1,N (2)- etheno-8-bromoguanosine-3',5'-cyclic monophosphorothioate, Rp-isomer (PET) reduced the stimulatory effect of DEA-NO on the activation of the MMP-13 promoter. Overexpression of the catalytic subunit of PKG1-alpha resulted in a 5- to 6-fold increase of the MMP-13 regulatory region over control cells. On the other hand, incubation with the mitogen-activated protein/extracellular signal-regulated kinase inhibitor 2'-amino-3'-methoxyflavone (PD98059) significantly reduced DEA-NO and 8-Br-cGMP promoter activation and mRNA expression of MMP-13 in transfected BAEC. Moreover, a complex between PKG1-alpha and the G-protein Raf-1, an upstream activator of the extracellular signal-regulated kinase signaling pathway, was detected in cells overexpressing PKG1-alpha or treated either with DEA-NO or 8-Br-cGMP. Thus, we propose that the NO-cGMP-PKG pathway enhances MMP-13 expression by the activation of ERK 1,2. This effect of NO may be important in the context of pathophysiological conditions such as inflammation or atherogenesis [corrected].

Abstract
Inflammatory cytokines play important roles in coronary artery disease. We investigated the clinical significance of monocyte-related cytokine expression in patients with angina pectoris. We studied 26 patients with stable effort angina and 20 patients with unstable angina in whom stenotic lesions of the coronary arteries were confirmed by selective coronary angiography. Plasma levels of interleukin-6 (IL-6), macrophage colony stimulating factor (MCSF), and monocyte chemoattractant protein-1 (MCP-1) were measured. Plasma levels of IL-6, MCSF, and MCP-1 in patients with unstable angina were significantly higher than those in patients with stable angina or control subjects. Patients with unstable angina were further divided into sub-groups according to their clinical classification; Levels of IL-6, MCSF, and MCP-1 in patients, who had anginal attacks at rest within the 48 h prior to admission (Braunwald class IIIB) were significantly higher than those in patients, who did not have attacks at rest (class IB). Five unstable patients, who were refractory to medical therapy and were referred for emergency coronary revascularization showed marked elevation of plasma MCSF and MCP-1 levels. In conclusion, plasma levels of monocyte-related cytokines were elevated in unstable angina. These increases were marked in patients with unstable angina with recent ischemic attack at rest, suggesting that activation of monocytes is involved in vulnerability of underlying atheromatous plaque.

Abstract
OBJECTIVES We sought to investigate the effects of intensive cholesterol reduction on large artery stiffness and blood pressure in normolipidemic patients with isolated systolic hypertension (ISH). BACKGROUND Isolated systolic hypertension is associated with elevated cardiovascular morbidity and mortality and is primarily due to large artery stiffening, which has been independently related to cardiovascular mortality. Cholesterol-lowering therapy has been efficacious in reducing arterial stiffness in patients with hypercholesterolemia, and thus may be beneficial in ISH. METHODS In a randomized, double-blinded, cross-over study design, 22 patients with stage I ISH received three months of atorvastatin therapy (80 mg/day) and three months of placebo treatment. Systemic arterial compliance was measured noninvasively using carotid applanation tonometry and Doppler velocimetry of the ascending aorta. RESULTS Atorvastatin treatment reduced total and low-density lipoprotein cholesterol and triglyceride levels by 36 +/- 2% (p < 0.001), 48 +/- 3% (p < 0.001) and 23 +/- 5% (p = 0.003), respectively, and increased high density lipoprotein cholesterol by 7 +/- 3% (p = 0.03). Systemic arterial compliance was higher after treatment (placebo vs. atorvastatin: 0.36 +/- 0.03 vs. 0.43 +/- 0.05 ml/mm Hg, p = 0.03). Brachial systolic blood pressure was lower after atorvastatin treatment (154 +/- 3 vs. 148 +/- 2 mm Hg, p = 0.03), as were mean (111 +/- 2 vs. 107 +/- 2 mm Hg, p = 0.04) and diastolic blood pressures (83 +/- 1 vs. 81 +/- 2 mm Hg, p = 0.04). There was a trend toward a reduction in pulse pressure (71 +/- 3 vs. 67 +/- 2 mm Hg, p = 0.08). CONCLUSIONS Intensive cholesterol reduction may be beneficial in the treatment of patients with ISH and normal lipid levels, through a reduction in large artery stiffness.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are synthesized in response to diverse stimuli including cytokines, growth factors, hormones, and oxidative stress. METHODS Bovine aortic endothelial cells (BAEC) were stimulated with nitric oxide (NO) and MMP-13 expression and activity was assayed. RESULTS NO transcriptionally regulated matrix metalloproteinase-13 (MMP-13) expression in BAEC, while the cGMP analog 8Br-cGMP mimicked the effect of NO. In addition NO also stimulated the proteolytic processing of MMP-13 from the pro-enzyme to the final active form in a dose dependent manner. CONCLUSION NO transcriptionally regulates MMP expression and activity in the vascular endothelium. This effect of NO may be of pathophysiological importance in the context of angiogenesis, inflammation or atherogenesis.

Abstract
The expression of matrix metalloproteinases (MMPs) associated with AIDS-related cardiomypathies and cocaine abuse was examined in an in vitro coculture model. Human peripheral blood mononuclear cells (PBMCs), HIV infected or uninfected, were placed in coculture with primary human cardiac microvascular endothelial cells (HMVEC-C) in the presence or absence of the cocaine-inducible catecholamine norepinephrine (NE). Culture supernatants were assayed for MMP-1, -2, -3, -7, -9, and -13, and for tissue inhibitor of metalloproteinase 1 (TIMP-1) and TIMP-2, by enzyme-linked immunosorbent assay. Low levels of constitutively expressed MMP-1 and -2 were detected in individual cultures of HMVEC-C and PBMCs. NE did not induce MMP or TIMP expression by HMVEC-C and caused modest increases (3- to 4-fold) in MMP-1 and -2 by uninfected PBMCs. Increased levels of NE-induced MMP-1 (5-fold) and MMP -2 (15-fold) were detected in cocultures of HMVEC-C and uninfected PBMCs. HIV infection enhanced MMP-1 (46-fold) and MMP-2 (48-fold) and active MMP-7 (33-fold) and MMP-9 (50-fold) by PBMCs. Coculture of HIV-infected PBMCs with HMVEC-C increased MMP-1 (110-fold) and MMP-2 (307-fold) but not active MMP-7 and -9. The combination of NE, HIV infection, and coculture increased MMP-1 (126-fold) and MMP-2 (467-fold), and active MMP-7 (65-fold) and MMP-9 (75-fold). MMP-3 or-13 was not detected in any of the treatment groups and TIMP-1 and -2 appeared inversely proportional to the observed levels of MMPs. These results suggest that HIV infection, NE, and leukocyte endothelial interactions demonstrate separate and overlapping cooperative effects on the regulation of expression of TIMPs and MMPs associated with AIDS-related cardiomyopathies.

Abstract
This study investigated the clinical significance of matrix metalloproteinases (MMPs) in acute myocardial infarction (AMI) and the involvement of peripheral blood mononuclear cells (PBMCs), which are a possible source of MMPs in AMI. Forty patients with AMI were recruited. Plasma and PBMCs were isolated from peripheral blood on days 1, 7, 14 and 21 after the onset of AMI. Levels of MMP-1 and MMP-2 were measured by enzyme-linked immunosorbent assay. The MMP-1 level in the culture medium of PBMCs after incubation for 24h was designated as 'PBMC-MMP-1 level.' Plasma MMP-1 did not significantly change during the course of AMI, but the plasma MMP-2 levels increased gradually after the onset of AMI with maximum elevation on day 21 after onset. Plasma MMP-2 activity also became significantly elevated during the course of AMI. PBMC-MMP-1 levels in the patients were significantly higher than those in control subjects over the course of AMI. Significant positive correlations were observed between maximum PBMC-MMP-1 levels and maximum plasma C-reactive protein levels (r=+0.55, p<0.01) and left ventricular end-diastolic volume index (r=+0.63, p<0.001). In conclusion, plasma MMP-2 levels and activity and MMP-1 production by PBMCs are increased in patients with AMI. Inflammation after AMI may enhance production of MMP-1 by PBMCs. These changes may play an important role in the ventricular remodeling that occurs after AMI by promoting the degradation of the extracellular matrix.
