Abstract
The human body has a unique way of saying when something is wrong with it. The molecules in the body fluids can be helpful in the early detection of diseases by enabling health and preventing disease progression. These biomarkers enabling better healthcare are becoming an extensive area of research interest. Biosensors that detect these biomarkers are becoming the future, especially Point Of Care (POC) biosensors that remove the need to be physically present in the hospital. Detection of complex and systemic diseases using biosensors has a long way to go. Saliva-based biosensors are gaining attention among body fluids due to their non-invasive collection and ability to detect periodontal disease and identify systemic diseases. The possibility of saliva-based diagnostic biosensors has gained much publicity, with companies sending home kits for ancestry prediction. Saliva-based testing for covid 19 has revealed effective clinical use and relevance of the economic collection. Based on universal biomarkers, the detection of systemic diseases is a booming research arena. Lots of research on saliva-based biosensors is available, but it still poses challenges and limitations as POC devices. This review paper talks about the relevance of saliva and its usefulness as a biosensor. Also, it has recommendations that need to be considered to enable it as a possible diagnostic tool.

Biophys Rev 2023; 15:329-353. [PMID: 37396449 PMCID: PMC10310682 DOI: 10.1007/s12551-023-01068-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 05/21/2023] [Indexed: 07/04/2023] Open
Abstract
Myocardial infarctions (MIs) kickstart an intense inflammatory response resulting in extracellular matrix (ECM) degradation, wall thinning, and chamber dilation that leaves the heart susceptible to rupture. Reperfusion therapy is one of the most effective strategies for limiting adverse effects of MIs, but is a challenge to administer in a timely manner. Late reperfusion therapy (LRT; 3 + hours post-MI) does not limit infarct size, but does reduce incidences of post-MI rupture and improves long-term patient outcomes. Foundational studies employing LRT in the mid-twentieth century revealed beneficial reductions in infarct expansion, aneurysm formation, and left ventricle dysfunction. The mechanism by which LRT acts, however, is undefined. Structural analyses, relying largely on one-dimensional estimates of ECM composition, have found few differences in collagen content between LRT and permanently occluded animal models when using homogeneous samples from infarct cores. Uniaxial testing, on the other hand, revealed slight reductions in stiffness early in inflammation, followed soon after by an enhanced resistance to failure for cases of LRT. The use of one-dimensional estimates of ECM organization and gross mechanical function have resulted in a poor understanding of the infarct's spatially variable mechanical and structural anisotropy. To resolve these gaps in literature, future work employing full-field mechanical, structural, and cellular analyses is needed to better define the spatiotemporal post-MI alterations occurring during the inflammatory phase of healing and how they are impacted following reperfusion therapy. In turn, these studies may reveal how LRT affects the likelihood of rupture and inspire novel approaches to guide scar formation.

Plasma Levels of Matrix Metalloproteinases 2 and 9 in Patients with Chronic Chagas Heart Disease and Systemic Arterial Hypertension: Correlation with TGF-Beta Plasma Levels. Cardiol Res Pract 2023; 2023:8484697. [PMID: 37122872 PMCID: PMC10132902 DOI: 10.1155/2023/8484697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 03/21/2023] [Accepted: 03/28/2023] [Indexed: 05/02/2023] Open
Abstract
Background Chronic Chagas heart disease (CCHD) and systemic arterial hypertension (SAH) frequently coexists in areas where Chagas disease is endemic. The effects of the association of both conditions (CCHD-SAH) on the extracellular matrix (ECM) remodeling are unknown. Matrix metalloproteinases (MMP) 2 and 9 are involved in ECM remodeling. The aim of this study was to evaluate MMP 2 and MMP9 in CCHD-SAH patients and to correlate their levels with those of the profibrogenic cytokine TGF-beta. Methods We included 19 patients with CCHD-SAH, 14 patients with CCHD alone, and 19 controls matched by sex and age. MMP-2 and MMP-9 plasma levels were studied by gel zymography and showed as optical densities (OD). TGF-beta plasma levels were measured by double-ligand ELISA and expressed as pg/mL. Results Median (5th, 95th) MMP-2 plasma levels were 1224.7 OD (1160, 1433.5) in patients with CCHD alone, 1424.1 OD (1267.5, 1561) in patients with CCHD-SAH, and 940 OD (898.1, 1000.8) in controls (p=0.001). MMP-9 plasma levels were 1870 OD (1740, 1904.1) in patients with CCHD alone, 1754.6 OD (1650, 2049) in those with CCHD-SAH and 89.7 OD (80, 96) in controls (p=0.0003). MMP-9 plasma levels were higher than those of MMP 2 in patients with CCHD-SAH (p=0.01). No correlation was found between TGF-beta plasma levels with MMP-2 serum levels (r = 0.12; p=0.7), but a moderate negative correlation (r = -0.46; p=0.048) was observed between TGF-beta and MMP-9 plasma levels. Conclusions MMP-2 and especially MMP-9 may play a role in the ECM remodeling process in patients with CCHD-SAH. TGF-Beta may counteract the MMP effect on the ECM remodeling process in patients with CCHD-SAH.

Abstract
Ischemia/reperfusion (I/R) injury is accompanied by an increase of matrix metalloproteinase 2 (MMP-2) activity, which degrades heart contractile proteins. The aim of the study was to investigate the effect of MMP-2 small interfering RNA (MMP-2 siRNA) administration on I/R heart. Isolated rat hearts perfused by the Langendorff method were subjected to I/R in the presence or absence of MMP-2 siRNA. The hemodynamic parameters of heart function were monitored. Lactate dehydrogenase (LDH) activity was measured in coronary effluents. Activity and concentration of MMPs in the hearts were measured. Concentration of troponin I (TnI) in coronary effluents was examined as a target for MMP-2 degradation. Recovery of heart mechanical function was reduced after I/R; however, administration of MMP-2 siRNA resulted in restoration of proper mechanical function (p < 0.001). LDH activity was decreased after the use of MMP-2 siRNA (p = 0.02), providing evidence for reduced cardiac damage. Both MMP-2 and MMP-9 syntheses as well as their activity were inhibited in the I/R hearts after siRNA administration (p < 0.05). MMP-2 siRNA administration inhibited TnI release into the coronary effluents (p < 0.001). The use of MMP-2 siRNA contributed to the improvement of heart mechanical function and reduction of contractile proteins degradation during I/R; therefore, MMP-2 siRNA may be considered a cardioprotective agent.

Abstract
Aim:
Matrix metalloproteinases (MMPs) play critical roles in acute myocardial infarction (AMI). This trial was conducted to determine the potential effects of higher-dose rosuvastatin on circulating MMP levels in patients with AMI.
Methods:
This was a multicenter, open-label, 1:1 randomized, parallel-group study. Patients with AMI were randomly assigned to the appropriate-dose group (10 mg rosuvastatin once daily) or the low-dose group (2.5 mg rosuvastatin once daily) within 24 hours after percutaneous coronary intervention. MMP-2 and MMP-9 levels were measured on day 1 and at week 4, 12, and 24 after enrollment. The primary endpoint was the change in MMP levels at 24 weeks after enrollment. The secondary endpoints were change in MMP levels at day 1 and weeks 4 and 12 after enrollment.
Results:
Between August 2017 and October 2018, 120 patients with AMI from 19 institutions were randomly assigned to either the appropriate-dose or the low-dose group. There were 109 patients who completed the 24-week follow-up. The primary endpoint for both MMP-2 and MMP-9 was not significantly different between the two groups. The change in the active/total ratio of MMP-9 at week 12 after baseline was significantly lower in the appropriate-dose group compared with the low-dose group (0.81 [−52.8–60.1]% vs. 70.1 [−14.5–214.2]%,
P
=0.004), while the changes in MMP-2 were not significantly different between the two groups during the study period.
Conclusions:
This study could not demonstrate the superiority of appropriate-dose of rosuvastatin in inhibiting serum MMPs levels in patients with AMI.

Abstract
Depression is often triggered by prolonged exposure to psychosocial stressors and associated with coronary heart disease (CHD). Matrix metalloproteinases (MMPs) are involved in the pathogenesis of various emotional and cardiovascular disorders. The purpose of this study was to investigate whether Kai‑Xin‑San (KXS), which may terminate the signaling of MMPs, exerts antidepressant‑like and cardioprotective effects in a myocardial infarction (MI) plus depression rat model. Rats were randomly assigned to five groups: A normal control (control group), a celisc‑injection of isopropyl adrenaline group (ISO group), depression (depression group), an ISO + depression (depression + ISO group), and an ISO + depression group treated with intragastric administration of 1,785 mg/kg KXS (KXS group). Behavioral changes, echocardiography, biochemical index, matrix metalloproteinase (MMP) and apoptosis‑related proteins were assessed. Compared with the depression + ISO group, KXS significantly improved stress‑induced alterations of behavioral parameters and protected the heart by enlarging the left ventricular (LV) fractional shortening (FS) and LV ejection fraction (EF). Moreover, KXS significantly attenuated ISO + depression‑induced MMP‑2 and MMP‑9 expression at the mRNA and protein level and decreased TIMP in the heart compared to the complex model group. Myocardial apoptosis was significantly attenuated by KXS by regulating the Bcl‑2/Bax axis. These results indicated that MI comorbid with depression may damage the MMP balance in the central and peripheral system, and KXS may have a direct anti‑depressive and cardio‑protective effect by regulating the level of MMPs and associated myocardial apoptosis. It is promising to further explore the clinical potential of KXS for the therapy or prevention of MI plus depression comorbidity disease.

Abstract
Matrixmetalloproteinases (MMP) 2 and 9 as well as tissue inhibitor of metalloproteinases (TIMP) 1 were tested as markers of myocardial early ischemia/infarctions. Experiments with an animal model, the isolated Langendorff heart, and analysis of human tissue samples drawn during autopsies were performed. Results of the experiments with the Langendorff model implied that the detectable amount of the markers might increase early after the onset of ischemia, in less than one hour, under ideal conditions. The results of the examined human cases showed that MMP-2 is constantly detectable in human myocardial tissue with an increased amount in case of an infarction with longer survival times. MMP-9 and TIMP-1 were negative in control cases, distinct positive staining results were obtained mainly in cases of infarctions with longer survival times and only rarely in those with a short survival time. According to these results MMPs and TIMPs do not qualify as first choice markers of myocardial infarctions. As an interesting side finding in the Langendorff experiments, positive staining results for all three markers were seen in myocardial areas that were mechanically traumatized by ECG-electrodes or ligation of blood vessels. These findings make the markers interesting for forensic wound age estimation.

Abstract
AIM To study the impact of a polymorphic variant of the matrix metalloproteinase-3 (MMP-3) gene on the development and course of chronic heart failure (CHF) in patients with coronary heart disease. SUBJECTS AND METHODS A total of 277 patients with New York Heart Association (NYHA) Functional Class (FC) II-IV CHF were examined. MMP-3 -1171 5A/6A genetic polymorphism was studied by polymerase chain reaction. A control group included 136 patients (mean age 53.6 ± 4.8 years) with no signs of cardiovascular diseases, as evidenced by the examination. RESULTS The frequency of the 5A allele and the 5A/5A genotype of the 1171 5A/6A polymorphic locus in the MMP-3 gene proved to be higher in the patients with CHF than that in the control group. Thus, the variability of the 5A allele (odds ratio (OR), 1.39; 95% confidence interval (CI): 1.033 to 1.869; p = 0.03) and the 5A/5A genotype (OR, 2.15; 95% CI: 1.131 to 4.070; p = 0.02) was associated with increased risk for CHF. There were significant differences in the frequency of MMP-3 alleles and genotypes in relation to FC of CHF. The frequency of the 5A/5A genotype was substantially higher in the patients with NYHA FC IV CHF than that in those with NYHA FC II CHF (32.8% versus 15.2%; p = 0.039). The frequency of the 5A allele was significantly higher in the patients with NYHA FC IV CHF than that in those with NYHA FC II CHF (55.5% and 39.3%; respectively; p = 0.019). Thus, the carriage of the 5A allele and the 5A/5A genotype of the 1171 5A/6A polymorphic locus in the MMP-3 gene is a risk factor of severe CHF. CONCLUSION The determination of MMP-3 -1171 5A/6A polymorphism may be recommended for the early prediction of a risk for the development and severe course of CHF.

Abstract
Previous studies have yielded controversial results related to the contribution of matrix metalloproteinase-2 (MMP-2) -1306 C/T and -735 C/T polymorphisms in the progression of coronary artery disease (CAD). This study aimed to provide strong evidence for the role of the 2 polymorphisms in genetic risk of CAD.The human case-control studies regarding the association of MMP-2 polymorphisms with CAD risk were systematically identified through online databases (PubMed, Embase, the Cochrane Library, and CNKI) and manual search. Inclusion criteria were defined for the eligible studies. The fixed-effects meta-analysis was performed to combine the values when homogeneity was indicated. Alternatively, the random-effects meta-analysis was utilized.A total of 2118 samples were analyzed in the meta-analysis of -1306 C/T. The odds ratio for the initially tested genetic model was 0.93 (95% confidence interval: 0.78-1.10 under TT + CT vs CC). The remaining comparisons similarly showed -1306 C/T genotypes were not significantly associated with the risk of CAD. We noted the same trend when data were retrained to myocardial infarction studies. Meta-analysis of -735 C/T suggested no clear association with the development of CAD.The results of the current work fail to support a significant involvement of MMP-2 -1306 C/T and -735 C/T polymorphisms in the risk of developing CAD.

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
Background and Objective Analysis of inflammatory biomarkers in saliva could offer an attractive opportunity for the diagnosis of different systemic conditions specifically in epidemiological surveys. The aim of this study was to investigate if certain salivary biomarkers could be used for detection of common systemic diseases. Materials and Methods A randomly selected sample of 1000 adults living in Skåne, a county in the southern part of Sweden, was invited to participate in a clinical study of oral health. 451 individuals were enrolled in this investigation, 51% women. All participants were asked to fill out a questionnaire, history was taken, a clinical examination was made and stimulated saliva samples were collected. Salivary concentrations of IL-1β, -6, -8, TNF-α, lysozyme, MMP-8 and TIMP-1 were determined using ELISA, IFMA or Luminex assays. Results Salivary IL-8 concentration was found to be twice as high in subjects who had experience of tumour diseases. In addition, IL-8 levels were also elevated in patients with bowel disease. MMP-8 levels were elevated in saliva from patients after cardiac surgery or suffering from diabetes, and muscle and joint diseases. The levels of IL-1β, IL-8 and MMP-8, as well as the MMP-8/TIMP-1 ratio were higher in subjects with muscle and joint diseases. Conclusion Biomarkers in saliva have the potential to be used for screening purposes in epidemiological studies. The relatively unspecific inflammatory markers used in this study can not be used for diagnosis of specific diseases but can be seen as markers for increased systemic inflammation.

Abstract
AIM Was to evaluate the role of seven matrix metalloproteinase (MMP) polymorphisms in the genetic susceptibility to develop myocardial infarction in Mexican individuals. METHODS Seven polymorphisms in the MMP genes were genotyped by 5' exonuclease TaqMan genotyping assays in 300 patients with myocardial infarction and 300 healthy unrelated controls. RESULTS A similar distribution of MMP2-1306 (rs243865), MMP2-790 (rs243864), MMP2-735 (rs22850553), MMP7-153(rs11568819), MMP7-181(rs11568818), and MMP12-82(rs2276109) polymorphisms was observed in both studied groups. On the other hand, patients showed increased frequencies of MMP2-1575 A allele and AA genotype when compared to controls (pC= 0.001; OR= 1.58 and pC= 0.036; OR= 2.37, respectively). According to the dominant model, individuals with AG+AA genotypes had a 1.65-fold increased risk of developing the disease (p= 0.002). After adjusting for known risk factors, we found a significant contribution of gender, BMI, smoking habit, diabetes mellitus, and hypertension to the inheritance model. In this analysis, individuals with the-1575 AA genotype had a 4.23-fold increased risk of developing MI (p= 0.003). On the other hand, an association of the MMP12-82 polymorphism with the extent of coronary artery disease (CAD) was observed. In our study, it was possible to distinguish two risk haplotypes and one protective haplotype for this disease in the MMP2 gene. CONCLUSIONS The results suggest that the MMP2-1575 (rs243866) gene polymorphism could be involved in the risk of developing myocardial infarction in Mexican individuals.

Abstract
Matrix metalloproteinase-2 (MMP-2) is a zinc dependent endonuclease that degrades type IV collagen, the major structural component of basement membranes. MMP-2 functional promoter polymorphism G1575A affects circulating level of MMP-2 and may be considered an important genetic determinant of cardiovascular disease (CVD) in systemic lupus erythematosus (SLE) patients. In this study, association between MMP-2 1575A allele with serum MMP-2, neopterin and lipid-lipoprotein levels and with SLE and developing CVD was investigated. The present case-control study consisted of 109 SLE patients with and without CVD (mean age, 35.6 years) and 101 gender- and age-matched, unrelated, healthy controls (mean age, 37.1 years) from the population in the west of Iran. MMP-2 1575G/A polymorphism was detected by polymerase chain reaction (restriction fragment length polymorphism) PCR-RFLP, serum MMP-2, neopterin and lipid levels were determined by enzyme-linked immunosorbent assay (ELISA), high-performance liquid chromatography (HPLC) and enzyme assay, respectively. The presence of MMP-2 G1575A allele was found to be associated with SLE and developed CVD (OR = 1.78, p = 0.029 and OR = 3.43, p = 0.025, respectively). The SLE patients with MMP-2 A (G/A + A/A) allele had higher MMP-2 activity (301 ± 166 vs. 194 ± 35.5, p = 0.002), neopterin (29.4 ± 39.4 vs. 7.3 ± 4.6, p = 0.005), LDL-C (120 ± 25.7 vs. 87 ± 39.3, p = 0.045) and lower HDL-C (39.6 ± 11 vs. 45.9 ± 11.8, p = 0.031) levels than the control subjects. There was a significantly positive correlation between MMP-2 level with neopterin, total cholesterol and TG levels and negative correlation with HDL-C level in SLE patients with CVD. MMP-2 G1575A allele may be a risk factor for SLE. The carriers of this allele have high levels of MMP-2, neopterin, total cholesterol and TG and lower levels of HDL, thus, they are more likely to develop heart disease.

Abstract
Mercury (Hg) exposure is associated with disease conditions, including cardiovascular problems. Although the mechanisms implicated in these complications have not been precisely defined yet, matrix metalloproteinases (MMPs) may be involved. The gene encoding MMP-2 presents genetic polymorphisms which affect the expression and activity level of this enzyme. A common polymorphism of MMP-2 gene is the C(-1306)T (rs 243865), which is known to disrupt a Sp1-type promoter site (CCACC box), thus leading to lower promoter activity associated with the T allele. This study aimed at examining how this polymorphism affects the circulating MMP-2 levels and its endogenous inhibitor, the tissue inhibitor of metalloproteinase-2 (TIMP-2) in 210 subjects environmentally exposed to Hg. Total blood and plasma Hg concentrations were determined by inductively coupled plasma-mass spectrometry (ICP-MS). MMP-2 and TIMP-2 concentrations were measured in plasma samples by gelatin zymography and ELISA, respectively. Genotypes for the C(-1306)T polymorphism were determined by Taqman® Allele Discrimination assay. We found a positive association (p=0.0057) between plasma Hg concentrations and MMP-2/TIMP-2 (an index of net MMP-2 activity). The C(-1306)T polymorphism modified MMP-2 concentrations (p=0.0465) and MMP-2/TIMP-2 ratio (p=0.0060) in subjects exposed to Hg, with higher MMP-2 levels been found in subjects carrying the C allele. These findings suggest a significant interaction between the C(-1306)T polymorphism and Hg exposure, possibly increasing the risk of developing diseases in subjects with the C allele.

Abstract
OBJECTIVES Matrix metalloproteinases (MMPs) play an important role in early atherosclerosis, plaque rupture, extracellular matrix remodeling, and myocardial infarction (MI). MMP gene polymorphisms contribute to the risk of developing cardiovascular disease. We designed to investigate the association of acute MI (AMI) with a polymorphism in the human MMP-1, 2, 3, and 9 genes in Iranian patients with AMI. METHODS Genomic DNA of 400 enrolled patients with AMI and 200 controls was extracted from their blood samples. The -1607 1G/2G MMP-1, -1306 C/T MMP-2, -1171 5A/6A MMP-3, -1562 C/T MMP-9 polymorphisms were detected. Plasma levels of MMPs were analyzed. RESULTS There are significant differences in MMP-3 '5A' allele and genotype in the patients with AMI comparing with controls. However, no significant differences were observed in MMP-1, 2, and 9 allele frequencies between the patients and controls. Differences between plasma levels of MMPs were significant in the patients than in controls. There were statistically significant differences between plasma MMP-3 in carriers of 5A allele compared with 6A allele. MMP-9 plasma levels were significantly higher in the carriers of -1306 TT and -1306 CT than CC. However, there were no statistically significant association between genetic variation of MMP-1, 2, and 3 in the patients and their plasma levels. CONCLUSION These data suggest that MMP genotyping such as genetic polymorphism in MMP-3 might be helpful in determining susceptibility to AMI in Iranian patients. In addition, susceptibility to AMI might be related to MMP-9 gene expression, which affects its plasma levels.

Abstract
The serum levels of matrix metalloproteinases (MMPs) increase during chronic heart failure (HF) and the MMP-2 are related to a poor prognosis. However, the roles of MMP-2 in acute HF (AHF) remain unclear. We investigated the change and clinical significance of MMP-2 in these conditions. The serum levels of MMP-2 were measured in 83 AHF patients before starting treatment (day 1), 3 (day 3) and 7 (day 7) days after admission, and before discharge (predischarge). MMP-2 decreased rapidly and significantly from day 3 to day 1 (902.9 ± 304.2 versus 1220.4 ± 330.5 ng/mL; P < 0.0001), whereas that of MMP-2 was not significantly different on day 7 and at predischarge (894.7 ± 278.9 and 920.0 ± 269.6 ng/mL, respectively) compared to day 3. We evaluated the relationships between ΔMMPs, defined as the changes in MMPs from day 1 to day 3 and HF events including cardiac death, readmission to hospital for HF, and uncontrollable HF. The MMP-2 value was significantly (P = 0.004) more decreased in the event-free group (381.4 ± 256.5 ng/mL) than in the event group (211.9 ± 225.5 ng/mL) between day 1 and day 3. The results of the multivariate logistic regression model for predicting HF events found that the specific factor for HF events was ΔMMP-2. Cutoff values of ΔMMP-2 were determined and event-free curves were constructed. Kaplan-Meier curves showed that the prognosis was significantly better among the patients with reductions in ΔMMP-2 values of more than 342 ng/mL. The serum levels of MMP-2 decreased with improvements in AHF. Rapid decreases in MMP-2 may be important for a better clinical outcome in patients with AHF.

Abstract
Inflammation and ECM (extracellular matrix) remodelling play important roles in LV (left ventricular) remodelling following acute MI (myocardial infarction). Previous studies show elevated plasma MMP (matrix metalloproteinase) levels in patients with acute MI, but their sources are not clear. The recruitment of mononuclear cells into the infarcted myocardium is critical for inflammatory responses, but their exact roles in LV remodelling have not been fully investigated, as it is difficult to isolate and study the function of regional inflammatory cells. To address these questions, we isolated PBMCs (peripheral blood mononuclear cells) from blood samples of patients with acute MI or stable angina, or healthy controls (n=14, 8 and 12 respectively). PBMCs were cultured for 24 h and the MMP9 level in the culture medium was measured by gelatin zymography, and MMP9 gene expression was measured by real-time PCR. Two superarrays (ECM and adhesion molecules, and common cytokines; 84 genes included in each array) were employed to screen gene expression profiles by PBMCs in five patients with acute MI and five controls. We found that MMP9 expression by PBMCs at both the mRNA and protein levels was increased 2-fold (both P<0.05) in patients with acute MI compared with the two control groups. Notably, MMP2 was not expressed by PBMCs. Superarray screening revealed that PBMCs not only expressed MMPs, TIMPs (tissue inhibitors of metalloproteinases) and matrix proteins, but also served as an important source of cell adhesion molecules, inflammatory cytokines and growth factors. A total of 42 genes were differentially expressed in patients with acute MI compared with controls. Expression of selected genes was confirmed by real-time PCR. In conclusion, PBMCs constitute a key cellular source for elevated plasma MMP9, but not for MMP2. PBMCs also contribute to systemic and regional inflammation and matrix remodelling in acute MI.

Abstract
Background Matrix metalloproteinases (MMPs) constitute a family of zinc-dependent proteases (endopeptidases) whose catalytic action is the degradation of the extracellular matrix components. In addition, they play the major role in the degradation of collagen and in the process of tissue remodeling. The present clinical study investigated blood serum levels of metalloproteinases- 1, -2, -3 and -9 in patients with acute and chronic aortic dissection, thoracic aortic aneurysm and acute myocardial ischemia compared to healthy individuals. Methods The blood serum levels of MMP-1, -2, -3 and -9 were calculated in 31 patients with acute aortic dissection, 18 patients with chronic aortic dissection, 18 patients with aortic aneurysm and in 13 patients with acute myocardial ischemia, as well as in 15 healthy individuals who served as the control group. Serum MMP levels were measured by using an ELISA technique. Results There were significantly higher levels of MMP-3 in patients with acute myocardial ischemia as compared to acute aortic dissection (17.33 ± 2.03 ng/ml versus 12.92 ± 1.01 ng/ml, p < 0.05). Significantly lower levels of MMP-1 were found in healthy controls compared to all groups of patients (1.1 ± 0.38 ng/ml versus 2.97 ± 0.68 in acute aortic dissection, 3.09 ± 0.98 in chronic dissection, 3.16 ± 0.51 in thoracic aortic aneurysm and 4.58 ± 1.04 in acute myocardial ischemia, p < 0.05). Higher levels of MMP-1 and MMP-3 were detected on males. There was a positive correlation with increasing age (r = 0.38, p < 0.05). In patients operated for acute type A aortic dissection, the levels of MMP-1, MMP-3 and MMP-9 increased immediately after surgery, while the levels of MMP-2 decrease. At 24 hours postoperatively, levels of MMP -1, -2 and -9 are almost equal to the preoperative ones. Conclusion Measurement of serum MMP levels in thoracic aortic disease and acute myocardial ischemia is a simple and relatively rapid laboratory test that could be used as a biochemical indicator of aortic disease or acute myocardial ischemia, when evaluated in combination with imaging techniques.

Abstract
Milestones in the progression to heart failure following myocardial infarction (MI) are changes in left ventricular (LV) geometry and function, termed post-MI remodeling. Critical to this adverse remodeling process are changes in the expression, synthesis, and degradation of myocardial extracellular matrix (ECM) proteins. The myocardial ECM is not a passive entity but a complex and dynamic microenvironment that represents an important structural and signaling system within the myocardium. In particular, basic and clinical studies have provided conclusive evidence that abnormal and persistent activation of the ECM degradation pathway, notably through the matrix metalloproteinases (MMPs), contribute to adverse post-MI remodeling. This review examines recent clinical studies that provide further support to the hypothesis that a specific portfolio of MMPs are diagnostic and likely contributory to LV remodeling and the progression to heart failure after MI. Future translational and clinical research focused on the molecular and cellular mechanisms regulating ECM structure and function likely will contribute to an improved understanding of post-MI LV remodeling and yield novel therapeutic targets.

Abstract
BACKGROUND Matrix metalloproteinase (MMP)-1 may play a role in cardiovascular disease susceptibility by influencing plaque rupture via its ability to degrade extracellular collagens. METHODS AND RESULTS We performed a genome-wide association analysis of circulating MMP-1 levels using 500 K single-nucleotide polymorphisms (SNPs) to identify genes influencing variation in serum MMP-1 levels in 778 healthy Amish adults. Serum MMP-1 levels, logarithm transformed, and adjusted for age and sex, were screened for association with SNPs using mixed-model variance components to account for familial relatedness. Median MMP-1 level was 3.05 ng/mL (interquartile range: 1.82 to 5.04 ng/mL) with an estimated heritability of 81% (P<0.0001). Serum MMP-1 levels were strongly associated with a cluster of 179 SNPs extending over an 11.5-megabase region on chromosome 11q. The peak association was with rs495366 (P = 5.73 x 10(-34)), located within the region between MMP-1 and MMP-3 and having a minor allele frequency of 0.36. Two other SNPs within the 11q region, rs12289128 and rs11226373, were strongly associated with MMP-1 levels after accounting for rs495366 (P < or = 10(-7)). These 3 SNPs explained 31% of the variance in MMP-1 levels after adjusting for age and sex. CONCLUSIONS This study provides strong evidence that the serum MMP-1 level is highly heritable and that SNPs near MMPs on chromosome 11q explain a significant portion of the variation in MMP-1 levels. Identification of the genetic variants that influence MMP-1 levels may provide insights into genetic mechanisms of cardiovascular disease.

Abstract
BACKGROUND Selective induction of myocardial matrix metalloproteinases (MMPs) has been reported to occur in human nonischemic dilated cardiomyopathy (DCM). We aimed to evaluate the utility of serum MMPs for risk stratification of patients with DCM. METHODS AND RESULTS We measured serum levels of MMP-2, MMP-3, and MMP-9 using enzyme-linked immunosorbent assay in 71 patients with mild to moderate DCM (left ventricular ejection fraction = 28.3 +/- 11.5%). The primary end point was the composite incidence of cardiac death and hospitalizations for worsening heart failure. During the follow-up period (mean, 28 +/- 16 months), 19 patients had major cardiac events with sudden cardiac death in 6 cases and hospitalizations for worsening heart failure in 13 cases. Multivariate analysis revealed that MMP-3 and B-type natriuretic peptide were significant independent predictors of cardiac events in patients with DCM (hazard ratio 1.41, P = .012; hazard ratio 2.72, P = .048, respectively). According to the Kaplan-Meier analyses of cumulative cardiac event-free rates of the two groups that were based on the median levels of MMPs, the differences in the cardiac event-free curves were significant only for MMP-3 (P = .009). Moreover, patients with elevations of both MMP-3 and B-type natriuretic peptide were found to have the poorest prognosis. CONCLUSION Our results may address the utility of serum MMP-3 for risk stratification of patients with DCM.

Abstract
The authors hypothesized that matrix metalloproteinase (MMP)-2, -9, and tissue inhibitor metalloproteinase (TIMP)-1, -2 would be abnormal in acute coronary syndromes (ACSs). MMP-2, -9, and TIMP-1, -2 plasma levels were measured in diabetic patients with ACSs compared to nondiabetic patients with ACSs. A total of 46 diabetic and 78 nondiabetic patients with ACSs were enrolled. The following parameters were measured: body mass index (BMI), glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment index (HOMA index), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (Tg), lipoprotein(a) [Lp(a)], plasminogen activator inhibitor-1 (PAI-1), homocysteine (Hct), fibrinogen (Fg), high-sensitivity C-reactive protein (hs-CRP), and plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2. Significant HbA1c, FPG, FPI, HOMA index, DBP, Tg, Hct, and Fg increases were present in the diabetic group with ACSs, whereas hs-CRP was lower in these patients compared to nondiabetic patients with ACSs. MMP-9, TIMP-1, and TIMP-2 plasma levels were higher in diabetic patients with ACSs compared to nondiabetic patients with ACSs. MMP-9, TIMP-1, and TIMP-2 plasma levels were increased in diabetic patients with ACSs, which may reflect abnormal extracellular matrix metabolism in diabetes during acute event.

Abstract
OBJECTIVES We hypothesized that molecules active in vascular remodeling (i.e. MMPs and their TIMPs) could be modified in diabetic patients, as indirect markers of the diabetes related generalized abnormality of vascular activity. To test this hypothesis, we measured the plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 in type 2 diabetic patients and in healthy subjects. METHODS We enrolled 181 diabetic patients and 165 controls. We measured body mass index (BMI), glycosylated hemoglobin (HbA(1c)), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment index (HOMA index), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (Tg), lipoprotein(a) [Lp(a)], plasminogen activator inhibitor-1 (PAI-1), homocysteine (Hct) fibrinogen (Fg), high sensitivity C-reactive protein (hs-CRP), and plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2. RESULTS A significant increase (P<0.0001) of BMI, HbA(1c), FPG, FPI, HOMA index, SBP, DBP, TC, LDL-C, Tg, Lp(a), PAI-1, Hct, Fg, and hs-CRP was present in the diabetic group, with a significant decrease (P<0.0001) of HDL-C levels compared to healthy subjects. MMP-2 and MMP-9 levels were significantly higher (P<0.0001) in diabetic patients. Significant TIMP-1, and TIMP-2 increase was also observed (P<0.0001) in the diabetic group. CONCLUSION Plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 are increased in diabetic patients which may reflect abnormal extracellular matrix (ECM) metabolism.

Abstract
Although left ventricular (LV) remodeling may be adaptive in early phases of cardiac injury, continued remodeling is a pathologic process that is associated with poor prognosis and diminished cardiac function. Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes involved in the degradation of myocardial extracellular proteins and have been implicated in adverse cardiac remodeling. There is a growing body of literature that supports the role of specific MMPs in cardiac remodeling in both animal models and clinical studies. Conventional imaging of physiologic indices, such as perfusion and function, have been used to monitor LV remodeling. Recently, the potential advantage of targeted imaging of MMPs has been demonstrated, particularly if this is linked with physiologic imaging.

Abstract
OBJECTIVES To evaluate the feasibility of an assay for urinary levels of matrix metalloproteinases (MMPs) and the potential usefulness of urinary MMPs as a marker of coronary atherosclerosis or acute coronary syndromes (ACS). METHODS AND RESULTS We measured urine and plasma MMP-9, MMP-2 and urine tissue inhibitor of metalloproteinase (TIMP-1) in patients with ACS (n=27), patients with coronary artery disease (CAD), but no clinical instability (n=47) and a group of healthy volunteers (n=15) who were <35 years of age, had no risk factors for CAD and did not undergo angiography. Compared with volunteers, patients with ACS and CAD had higher urine MMP-9, urine TIMP-1, plasma MMP-9 and plasma MMP-2 levels, but these did not differ between those with CAD and ACS. Using the volunteers to roughly establish an upper limit of normal, 84% of the urine TIMP-1 values and 95% of the urine MMP-9 values were abnormally elevated among those with CAD and ACS. CONCLUSIONS Urine MMP-9 and TIMP-1 levels are elevated in patients with CAD and ACS compared with healthy volunteers. A high percent of patients with CAD or ACS had elevated urine values of MMP-9 and TIMP-1 suggesting these variables might be a useful marker of atherosclerotic disease.

Abstract
PURPOSE OF REVIEW Disturbances of the synthesis and breakdown of the extracellular matrix of arterial walls have emerged as key features of the atherosclerotic process. Altered levels of circulating extracellular matrix markers have frequently been observed in relation to manifestations of atherosclerotic disease and its risk factors. RECENT FINDINGS Research has been focused on the matrix-degrading metalloproteinases, their tissue inhibitors, and procollagen peptides. The most promising matrix metalloproteinase is matrix metalloproteinase-9, which has been observed to predict rapid coronary artery narrowing, ischemic heart disease incidence, abdominal aortic aneurysm expansion, worse outcome in stroke patients, and cardiovascular death. The use of tissue inhibitors of metalloproteinases for prognostication is uncertain thus far. The procollagen marker with most prognostic potential is the marker for type III collagen turnover rate, the N-terminal propeptide PIIINP, higher levels of which predict an adverse outcome after a myocardial infarction and in chronic heart failure, and portend abdominal aortic aneurysm expansion and risk of rupture. Also, the marker for type I collagen synthesis, the C-terminal propeptide PICP, predicts adverse outcomes following myocardial infarction and in chronic heart failure. Extracellular matrix remodeling is also a promising therapeutic target, being favorably affected by several conventional cardiovascular drugs and select dietary interventions. Synthetic matrix metalloproteinase inhibitors are also under development. SUMMARY Circulating matrix markers have emerged as candidate biomarkers for predicting risk of subsequent atherosclerotic events. Future large longitudinal observational and intervention studies will determine the role of matrix biomarkers in diagnosis and prognostication, and as targets for intervention in cardiovascular diseases.

Abstract
Background—
Time-dependent activation of matrix metalloproteinases (MMPs) after myocardial infarction (MI) contributes to adverse left ventricular (LV) remodeling; however, noninvasive methods to monitor this process serially are needed.
Methods and Results—
MMP-targeted radiotracers were developed that displayed selective binding kinetics to the active MMP catalytic domain. Initial nonimaging studies were performed with a
111
In-labeled MMP-targeted radiotracer (
111
In-RP782) and negative control compound (
111
In-RP788) in control mice (Ctrl) and in mice 1 week after surgically induced MI. Localization of
111
In-RP782 was demonstrated within the MI by microautoradiography. A 334±44% increase (
P
<0.001 versus Ctrl) in relative retention of
111
In-RP782 was confirmed by gamma well counting of myocardium. Subsequent high-resolution dual-isotope planar and hybrid micro–single-photon emission computed tomography/CT imaging studies with an analogous
99m
Tc-labeled MMP-targeted radiotracer (
99m
Tc-RP805) and
201
Tl demonstrated favorable biodistribution and clearance kinetics of
99m
Tc-RP805 for in vivo cardiac imaging, with robust retention 1 to 3 weeks after MI in regions of decreased
201
Tl perfusion. Gamma well counting yielded a similar ≈300% increase in relative myocardial retention of
99m
Tc-RP805 in MI regions (Ctrl, 102±9%; 1 week, 351±77%; 2 weeks, 291±45%; 3 weeks, 292±41%;
P
<0.05 versus Ctrl). Myocardial uptake in the MI region was also significantly increased ≈5-fold when expressed as percentage injected dose per gram tissue. There was also a significant 2-fold increase in myocardial activity in remote regions relative to control mice, suggesting activation of MMPs in regions remote from the MI.
Conclusions—
This novel noninvasive targeted MMP radiotracer imaging approach holds significant diagnostic potential for in vivo localization of MMP activation and tracking of MMP-mediated post-MI remodeling.

Abstract
Myocardial remodeling invariably occurs in congestive heart failure (CHF) and is a response to a prolonged cardiovascular stress, which is characterized by a cascade of compensatory structural events. Remodeling of the myocardial interstitium occurs in CHF and likely contributes to the progression of the remodeling process. The myocardial matrix can be considered a biological highway in which a large amount of signaling proteins and structural proteins are being moved within the interstitium, entering and exiting the interstitial space, and docking to cellular components. The rates at which these events occur can accelerate and decelerate depending on the particular cardiac disease state and thereby can alter the course of myocardial remodeling. Once considered merely a scaffolding to align cells, the matrix plays a complex and divergent role in influencing cell behavior. For example, the matrix has a functional role in cell migration, proliferation, adhesion, and cell-to-cell signaling. In light of this, the myocardial matrix should not be regarded as merely a static structure, but rather, as a complex system of dynamic interactions between matrix molecules, signaling proteins, and transmembrane proteins. Specific strategies that are targeted at modifying activity along this matrix highway will likely alter the course of myocardial remodeling and heart failure.

Abstract
Although ischemia remains the leading cause of acute renal failure in humans, there is little information on the expression and activities of gelatinases of kidney glomeruli during ischemia–reperfusion injury. In this study, we used a unilateral ischemia–reperfusion model to investigate the activity and expression of gelatinases in glomeruli during acute ischemia. Unilateral ischemia was induced in rats by vascular clamping (30 min) followed by reperfusion (60 min) and isolation of glomeruli. The activity and expression of gelatinase proteins were determined by gelatin zymography and Western blotting. Gelatinase mRNA levels were evaluated by reverse transciptase-PCR. Ischemia and reperfusion increased serum creatinine levels, hallmark of acute renal failure. Ischemia induced mRNA and protein MMP-2 expression. There was strong stimulation of MMP-9 mRNA, both forms of dimeric MMP-9, and active mono meric MMP-9. In contrast to TIMP-1 decreasing, TIMP-2 protein and mRNA increased during ischemia. During reperfusion, there was a gradual reversal of the MMP-2 and MMP-9 levels and a strong inhibition of TIMP-1 and TIMP-2 at the protein and mRNA levels. Endocytic receptor LRP was increased during ischemia and returned to normal during reperfusion. Expression of MMP-9 docking receptor CD-44 was increased during reperfusion. Finally, ZO-1, an in vivo MMP-9 substrate, was degraded during ischemia, revealing that MMP-9 upregulated during ischemia was functional. Our data suggest that stimulation of gelatinase activity during ischemia could contribute to glomeruli injury, providing new therapeutic targets for acute renal failure in humans. In contrast, elevated monomeric MMP-9 activity due to TIMP-1 decrease during reperfusion may participate to glomerular recovery.Key words: gelatinases, ischemia-reperfusion, TIMPs, ZO-1, CD-44, LRP, glomeruli.

Abstract
BACKGROUND The overall goal of this study was to develop an assay procedure for measuring the relative abundance of tissue inhibitor of metalloproteinase (TIMP)-4 in plasma, and then use this approach to determine dynamic changes of TIMP-4 levels in hypertrophic obstructive cardiomyopathic (HOCM) patients after an acute myocardial infarction (MI). Matrix metalloproteinases (MMPs) contribute to tissue remodeling and are regulated by the endogenous TIMPs. TIMP-4 is observed to be expressed in higher abundance in the myocardium when compared with other types of tissues. Recent clinical studies have measured changes in TIMP-4 levels; however, these studies have been limited to measuring this protein from myocardial tissue samples. To date, no studies have monitored TIMP-4 levels in plasma samples. METHODS AND RESULTS Plasma TIMP-4 levels were examined (by semiquantitative immunoblotting) in normal (n=18) and HOCM (n=16) patients after alcohol-induced MI. Serial measurements of plasma TIMP-4 levels were examined up to 60 hours after alcohol-induced MI in patients with HOCM. Unglycosylated plasma TIMP-4 levels increased 250% in the HOCM patients when compared with normal controls. Total plasma TIMP-4 levels decreased by 20% at 30 hours after alcohol-induced MI. CONCLUSIONS The unique results demonstrated that an induction of a controlled MI, specifically through alcohol ablation, caused a reduction in plasma TIMP-4 levels in HOCM patients after alcohol-induced MI that would facilitate myocardial remodeling in the early post-MI setting.

Abstract
OBJECTIVES We studied the role of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in fibrosis formation in the transition from hypertrophy to heart failure (HF) as well as the cellular source of MMPs and TIMPs. BACKGROUND Human pressure-overloaded hearts are characterized by a significant increase in cardiac fibrosis. However, the contribution of the proteolytic/antiproteolytic system in aortic stenosis (AS) during hypertrophy progression has not yet been elucidated. METHODS Three groups of AS patients (I: EF >50%, n = 12; II: EF 50% to 30%, n = 10; III: EF <30%, n = 12) undergoing aortic valve replacement and seven controls were studied. Tissue samples were investigated by immunoconfocal microscopy, Western blotting, and zymography. RESULTS Quantitative analysis by immunoconfocal microscopy and Western blotting showed an upregulation of MMP-1, -2, -3, -9, -13, and -14 in group I and further increases in later stages. Tissue inhibitors of metalloproteinase-1 and -2 were enhanced and TIMP-4 was decreased in comparison to control. Gelatinolytic activity of MMP-2 significantly (p < 0.05) increased 1.2-fold (group I), 1.5-fold (group II), and 1.6-fold (group III) over control. The level of collagen I was significantly upregulated in all AS groups. Immunoconfocal microscopy showed that MMPs and TIMPs are produced predominantly by fibroblasts. The number of proliferating fibroblasts was significantly elevated during the transition to HF (0.67 n/mm(2)-control, 5.03-group III, p < 0.05). CONCLUSIONS In human hearts a continuous turnover of the extracellular matrix occurs during the progression from compensated hypertrophy to HF that is characterized by the upregulation of MMPs and inadequate inhibition by TIMPs. The altered balance between proteolysis/antiproteolysis with accompanying proliferation of fibroblasts results in fibrosis progression.

Abstract
Vascular lesion development is associated with an accumulation of extracellular matrix proteins within the vessel wall. The proteins are degraded by matrix metalloproteinases (MMPs). There is also evidence indicating a participation of the MMPs in the weakening of atherosclerotic plaque that predisposes to lesion disruption. The aim of the study was to test an association among haplotypes of four single nucleotide MMP-2 promoter polymorphisms and the angiographically confirmed coronary triple-vessel disease (TVD). Incidence of haplotypes of four MMP-2 promoter polymorphisms (-1575G/A, -1306C/T, -790T/G and -735C/T) determined by PCR reactions with restriction analyses in 187 patients with coronary TVD (153 men, 34 women, age median 65 years) was compared to 196 control subjects without clinical signs of coronary heart disease (131 men and 65 women, age median 60 years). The incidence of two similar haplotypes was found to be different between patients and healthy subjects. The haplotype GCTC was more frequent in the TVD patients (P=0.01) though the haplotype GCGC was identified only in healthy subjects (P=0.001). Interestingly, the GCTC is the most frequent polymorphic haplotype composed of four promoter SNPs localized in the MMP-2 gene (53% in healthy subjects vs. 66% in patients with TVD) and the haplotype GCGC is the least frequent polymorphic one (4.4% in healthy subjects vs. 0% in patients with TVD). Two different MMP-2 promoter haplotypes differing only in -790T/G allele are significantly more or less frequent in coronary TVD compared to non-ischemic persons. Thus, the -790T/G MMP-2 genotype might be used as a genetic marker representing MMP-2 promoter variability for the TVD with odds ratio for TT and TG genotypes 2.59, 95% confidential interval 1.21-5.55, P=0.009. The analysis of promoter MMP-2 gene variability could help us to understand individual susceptibility to MMP inhibitor treatment of the coronary artery disease.

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
Remodelling of extracellular matrix by activated matrix metalloproteinases is considered to contribute to progression of ventricle remodelling during chronic heart failure. The aim of this study was to associate two promoter polymorphisms, -790T/G and -735C/T, in the gene for matrix metalloproteinase (MMP)-2 (gelatinase A) with chronic heart failure (CHF). For this purpose, 164 patients (124 men, 40 women, median age 56 years, range 21-91 years) with CHF (functional class NYHA II-IV, ejection fraction median 25%, cardiothoracic index more than 50%) were compared with 196 control subjects without clinical signs of cardiovascular disease (131 men and 65 women, median age 56 years, range 27-84 years) in -790T/G and -735C/T MMP-2 genotype distributions and allelic frequencies. The genotypes were determined by polymerase chain reaction (PCR) with restriction analyses. A significant increase of the T allele of the -790T/G MMP-2 polymorphism (p = 0.04), as well as of the C allele of the -735C/T MMP-2 gene polymorphism, in patients with CHF was proven (p = 0.04). The heterozygote CT of the -735C/T MMP-2 polymorphism exhibits a 7 times higher odds ratio (OR) for the CHF patients with lower levels of total cholesterol (less than 5 mmol/l), especially for non-hypertensive CHF men (OR = 7.28, 95% confidence interval 1.51-35.03, p = 0.006). Determination of MMP polymorphisms in the regulatory area of the gene could help us to comprehend individual susceptibility of patients with CHF to MMP inhibitors based on known risks of MMP genotypes.

Abstract
There is increasing evidence that abnormal cytokine expression and increased metalloproteinase activity are implicated in the pathophysiology of acute coronary syndromes. This study investigates the serum profiles of representative metalloproteinases (MMP-1, -2, -9) and their tissue inhibitor (TIMP-1) in patients with myocardial infarction (MI) and unstable angina (UA) in relation to circulating proinflammatory cytokine (TNF-alpha and IL-6) activity. Furthermore, we examined the effects of a 30-day treatment with atorvastatin on serum levels of these inflammatory factors. Serum concentrations of MMP-1, -2, -9, TIMP-1, IL-6 and TNF-alpha were measured (enzyme-linked immunosorbent assay (ELISA) method) in 23 acute myocardial infarction patients and 20 unstable angina patients on 0 day, 1st, 3rd, 7th and 30th day after admission. Sixteen normal volunteers were used as healthy controls. Additionally, 12 patients of myocardial infarction group and 11 patients of unstable angina group were treated with atorvastatin (20 mg/day) for 30 days in a randomized design. In patients with myocardial infarction and unstable angina, serum levels of MMP-2, -9, TIMP-1, TNF-alpha and IL-6 were significantly higher than those of healthy controls in all time frames (p<0.05). In the group of unstable angina patients, we observed a statistically significant reduction in the levels of MMP-9, TIMP-1 and IL-6 after the 30-day atorvastatin administration. Our results suggest that serum MMPs, TIMP-1 and proinflammatory cytokines play an important role in the pathophysiology of the acute coronary syndromes. The reduction of these factors by short-term atorvastatin administration may provide a new insight into the pleiotropic effects of statins on unstable coronary artery disease.

Abstract
Ischemia-reperfusion (I/R) is thought to upregulate the expression and activity of matrix metalloproteinases (MMPs), which regulate myocardial and vascular remodeling. Previous studies have shown that transforming growth factor-beta(1) (TGF-beta(1)) can attenuate myocardial injury induced by I/R. TGF-beta(1) is also reported to suppress the release of MMPs. To study the modulation of MMP-1 by TGF-beta(1) in I/R myocardium, Sprague-Dawley rats were given saline and subjected to 1 h of myocardial ischemia [total left coronary artery (LCA) ligation] followed by 1 h of reperfusion (n = 9). Parallel groups of rats were pretreated with recombinant TGF-beta(1) (rTGF-beta(1), 1 mg/rat, n = 9) before reperfusion or exposure to sham I/R (control group). I/R caused myocardial necrosis and dysfunction, indicated by decreased first derivative of left ventricular pressure, mean arterial blood pressure, and heart rate (all P < 0.01 vs. sham-operated control group). Simultaneously, I/R upregulated MMP-1 (P < 0.01). Treatment of rats with rTGF-beta(1) reduced the extent of myocardial necrosis and dysfunction despite I/R (all P < 0.01). rTGF-beta(1) treatment also inhibited the upregulation of MMP-1 in the I/R myocardium (P < 0.05). To determine the direct effect of MMP-1 on the myocardium, isolated adult rat myocytes were treated with active MMP-1, which caused injury and death of cultured myocytes, measured as lactate dehydrogenase release and trypan blue staining, in a dose- and time-dependent manner (P < 0.05). Pretreatment with PD-166793, a specific MMP inhibitor, attenuated myocardial injury and death induced by active MMP-1. The present study for the first time shows that MMP-1 can directly cause myocyte injury or death and that attenuation of myocardial I/R injury by TGF-beta(1) may, at least partly, be mediated by the inhibition of upregulation of MMP-1.

Abstract
The left ventricular ejection fraction (LVEF) is one of the major prognostic factors after acute myocardial infarction (AMI) and matrix metalloproteinase-1 (MMP-1) is an enzyme responsible for extracellular collagen degradation and remodeling. The present study investigated whether the concentration of serum MMP-1 was associated with the LVEF after AMI. Blood was sampled on admission, and at 24 h, 3 days, 7 days, 2 weeks and 4 weeks in 24 patients with their first AMI. Left ventriculography was performed 4 weeks after the onset of AMI and the LVEF was calculated by center line method. MMP-1 concentrations were higher at 7 days and at 2 weeks than on admission (p<0.001), and at 7 days (r=-0.655, p=0.0005) and at 2 weeks (r=-0.636, p=0.0008) were negatively correlated with the LVEF. The patients with AMI were divided into high and low LVEF groups according to the results of left ventriculography. Although there were no differences in the clinical characteristics between the 2 LVEF groups, the MMP-1 concentrations at 24 h (p<0.01), 7 days (p<0.01) and 2 weeks (p<0.05) were lower in the high LVEF group than in low LVEF group. A high concentration of MMP-1 at the subacute phase after AMI predicts advanced left ventricular remodeling.

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
OBJECTIVES This study examined plasma levels of certain matrix metalloproteinase (MMP) and tissue inhibitor of matrix metalloproteinase (TIMP) species before and after alcohol-induced myocardial infarction (MI) in patients with hypertrophic obstructive cardiomyopathy (HOCM). BACKGROUND Matrix metalloproteinases contribute to tissue remodeling, and endogenous control of MMP activity is achieved by the concordant release and binding of TIMPs. Animal models of MI have demonstrated a role for MMP activation in myocardial remodeling. However, the temporal relationship of MMP and TIMP release following a controlled myocardial injury in humans remains unknown. METHODS Plasma levels for the gelatinases MMP-2 and MMP-9, and for the collagenases MMP-8 and MMP-13, as well as TIMP-1 profiles were examined (by enzyme-linked immunosorbent assay) at baseline and serially up to 60 h following alcohol injection into the septal perforator artery in order to induce an MI in 51 patients with HOCM (age 55 +/- 2 years). RESULTS Plasma creatine kinase (MB isoform), indicating myocardial injury, increased 2,150% 18 h post-MI (p < 0.05). Plasma MMP-9 increased by over 400% and MMP-8 by over 100% from baseline values by 12 h post-MI (p < 0.05 vs. baseline). A similar temporal profile was not observed for MMP-2 and MMP-13. In addition, a concomitant increase in plasma TIMP-1 levels did not occur post-MI. As a result, MMP/TIMP stoichiometry (MMP-9/TIMP-1 ratio) increased significantly post-MI, suggestive of reduced TIMP-1 mediated MMP-9 inhibition, which would potentially enhance extracellular myocardial remodeling. CONCLUSIONS These unique results demonstrated that induction of a controlled myocardial injury in humans, specifically through alcohol-induced MI, caused species- and time-dependent perturbations of MMP/TIMP stoichiometry that would facilitate myocardial remodeling in the early post-MI setting.

Abstract
BACKGROUND Changes in myocardial matrix metalloproteinases (MMPs) and the inhibitors of MMPs (TIMPs) have been demonstrated in congestive heart failure (CHF). The first objective of this study was to measure plasma profiles of MMPs and TIMPs in CHF patients (n = 24; 62 +/- 3 years; left ventricular ejection fraction [LVEF] = 24 +/- 2%) and age-matched nonfailing patients (n = 48; 63 +/- 2 years; LVEF >/= 55%). Cytokines such as tumor necrosis factor (TNF)-alpha can induce MMP expression in vitro. The second objective of this study was to determine the relationship between soluble TNF-alpha receptors (TNFR1; TNFR2) and MMP plasma profiles. METHODS AND RESULTS Plasma levels of MMP-2, MMP-9, MMP-8, TIMP-1, TIMP-2, TNF-alpha, TNFR1, and TNFR2 were measured by enzyme-linked immunosorbent assay kits. Plasma MMP-9 levels were increased in CHF patients (25 +/- 6 versus 72 +/- 15 ng/mL, P <.05). Interestingly, plasma levels of MMP-8 were decreased in CHF patients (16 +/- 2 versus 9 +/- 2 ng/mL, P <.05). The MMP-9/TIMP-1 ratio was increased by 3-fold, whereas the MMP-9/TIMP-2 ratio was increased by 16-fold in CHF patients (both P <.05). With a 48-week follow-up in CHF patients, an absolute reduction in plasma TNFR1 from baseline was accompanied by reduced MMP-9 levels (-30 +/- 16 ng/mL; P =.058), whereas stable or increased plasma TNFR1 resulted in persistently elevated MMP-9 levels. CONCLUSIONS The unique findings of this study were 2-fold. First, a discordant change in plasma MMP and TIMP levels occurred in CHF patients. Second, changes in cytokine activity were related to changes in plasma MMP levels. These changes in MMP/TIMP levels likely reflect the progression and/or acceleration of the LV remodeling process in CHF. Thus serial measurements of plasma MMP/TIMP levels may hold diagnostic/prognostic significance in CHF patients.

Abstract
The progression of left ventricular (LV) dysfunction is often accompanied by changes in LV geometry and myocardial architecture that can be defined as LV myocardial remodelling. An important event in LV myocardial remodelling is alterations in the extracellular matrix (ECM). A family of zinc-dependent proteases implicated in facilitating myocardial tissue remodelling by degrading components of the ECM are the matrix metalloproteinases (MMPs). The temporal expression of MMPs and the local tissue inhibitors of MMPs (TIMPs) appear to be differentially regulated in several cardiovascular disease states such as myocardial infarction, LV hypertrophy, and dilated cardiomyopathy. Both pharmacological and genetic modulation of myocardial MMP expression has been demonstrated to alter the course of LV myocardial remodelling and LV dysfunction. The induction of MMPs within the myocardium during the heart failure process probably results in liberation of bioactive molecules, proteolytic degradation of ECM structural proteins, and alterations in cell-cell contact and adhesion. Modifying MMP expression and activation may reduce this turmoil within the myocardial interstitium and, in turn, prove to be a useful therapeutic paradigm for heart failure treatment.
