Abstract
Carotid atherosclerosis (CA) and, especially, carotid artery stenosis (CAS), are associated with a high risk of cardiovascular events in subjects with type 2 diabetes (T2D). In this study, we aimed to identify risk factors and biomarkers of subclinical CA and CAS in T2D individuals. High-resolution ultrasonography of carotid arteries was performed in 389 patients. Ninety-five clinical parameters were evaluated, including diabetic complications and comorbidities; antihyperglycemic, hypolipidemic, and antihypertensive therapy; indices of glycemic control and glucose variability (GV); lipid panels; estimated glomerular filtration rate (eGFR); albuminuria; blood cell count; and coagulation. Additionally, serum levels of calponin-1, relaxin, L-citrulline, and matrix metalloproteinase-2 and -3 (MMP-2, -3) were measured by ELISA. In univariate analysis, older age, male sex, diabetes duration, GV, diabetic retinopathy, chronic kidney disease, coronary artery disease, peripheral artery disease, and MMP-3 were associated with subclinical CA. In addition to these factors, long-term arterial hypertension, high daily insulin doses, eGFR, and L-citrulline were associated with CAS. In multivariate logistic regression, age, male sex, BMI, GV, and eGFR predicted CA independently; male sex, BMI, diabetes duration, eGFR, and L-citrulline were predictors of CAS. These results can be used to develop screening and prevention programs for CA and CAS in T2D subjects.

Abstract
PURPOSE The relationship of the matrix metalloproteinase-3 (MMP-3) polymorphisms rs679620 and rs3025058 with ischemic stroke has received much attention. The aim of the present study was to perform a meta-analysis of published case-control studies to evaluate the cumulative evidence. METHODS We performed a search of ISI Web of Science, Embase, PubMed, and China National Knowledge Infrastructure databases. Pooled odds ratios (ORs) were appropriately derived from fixed-effects or random-effects models. RESULTS We identified seven eligible studies including 5,204 subjects. The pooled analysis showed that the MMP-3 rs679620 A allele carriers had increased risk of ischemic stroke compared with homozygotes for the G allele in Asians (AA + GA vs GG: OR =1.42, 95% CI: 1.05-1.91, P=0.022). Concerning the rs3025058 polymorphism, the results did not suggest an association between rs3025058 genotypes and ischemic stroke risk (5A5A + 6A5A vs 6A6A: OR =1.04, 95% CI: 0.73-1.47, P=0.844; 5A5A vs 6A5A + 6A6A: OR =1.14, 95% CI: 0.74-1.77, P=0.556; and 5A5A vs 6A6A: OR =1.11, 95% CI: 0.68-1.80, P=0.677). In subgroup analysis by ethnicity, no statistically significant associations were demonstrated for rs3025058 in Asians and Caucasians, respectively. There was no evidence for publication bias. CONCLUSION Our findings indicate that the rs679620 A allele carriers have increased risk of ischemic stroke in Asians, but there is no association between rs3025058 and ischemic stroke risk.

Abstract
Studies have demonstrated that matrix metalloproteinase-3 (MMP-3) is involved in the development and progression of atherosclerosis. However, there is no information available on the association of MMP-3 5A/6A polymorphism with recurrent ischemic stroke (IS) in different IS subtypes. We investigated the potential associations between MMP-3 serum level and -1171 5A/6A polymorphism and the recurrence of IS in a Chinese population. Consecutive acute first-ever IS patients were enrolled between August 2008 and October 2013. The genotypes of MMP-3 5A/6A polymorphism were determined using polymerase chain reaction-restriction fragment length polymorphism. IS recurrence was monitored after the index event and multivariate Cox proportional hazards model was constructed to identify factors related to future IS recurrence. A total of 1282 eligible patients were enrolled. During a 2-year follow-up period, 157 (12.25%) patients had recurrent events. MMP-3 level was significantly higher in patients with 5A/6A or 5A/5A genotype (22.72±7.29ng/ul) than in patients with 6A/6A genotype (20.48±7.58ng/ul), P<0.001. No interaction between MMP-3 5A/6A polymorphism and the risk of recurrence in total IS patients was found. The variant 5A/6A+5A/5A genotype and the 5A allele were significantly associated with a high risk of recurrence for large-artery atherosclerosis (LAA) (multivariate-adjusted, P=0.002, 0.001, respectively), but not for small-artery occlusion and cardioembolism. Our finding showed that MMP-3 5A/6A may be a useful biomarker for predicting recurrence for LAA stroke patients and 5A allele carrier may bear a higher risk of recurrence among patients with the subtype of LAA.

Abstract
Objective: Atherosclerosis is an inflammatory process that results in complex lesions or plaques that protrude into the arterial lumen. Carotid atherosclerotic plaque rupture, with distal atheromatous debris embolization, causes cerebrovascular events. This review aimed to explore research progress on the risk factors and outcomes of human carotid atherosclerotic plaques, and the molecular and cellular mechanisms of human carotid atherosclerotic plaque vulnerability for therapeutic intervention. Data Sources: We searched the PubMed database for recently published research articles up to June 2016, with the key words of “risk factors”, “outcomes”, “blood components”, “molecular mechanisms”, “cellular mechanisms”, and “human carotid atherosclerotic plaques”. Study Selection: The articles, regarding the latest developments related to the risk factors and outcomes, atherosclerotic plaque composition, blood components, and consequences of human carotid atherosclerotic plaques, and the molecular and cellular mechanisms of human carotid atherosclerotic plaque vulnerability for therapeutic intervention, were selected. Results: This review described the latest researches regarding the interactive effects of both traditional and novel risk factors for human carotid atherosclerotic plaques, novel insights into human carotid atherosclerotic plaque composition and blood components, and consequences of human carotid atherosclerotic plaque. Conclusion: Carotid plaque biology and serologic biomarkers of vulnerability can be used to predict the risk of cerebrovascular events. Furthermore, plaque composition, rather than lesion burden, seems to most predict rupture and subsequent thrombosis.

Abstract
Atherosclerosis leads to blockage of arteries, culminating in myocardial infarction, and stroke. The involvement of matrix-degrading metalloproteinases (MMPs) in atherosclerosis is established and many studies have highlighted the importance of various MMPs in this process. MMPs were first implicated in atherosclerosis due to their ability to degrade extracellular matrix components, which can lead to increased plaque instability. However, more recent work has highlighted a multitude of roles for MMPs in addition to breakdown of extracellular matrix proteins. MMPs are now known to be involved in various stages of plaque progression: from initial macrophage infiltration to plaque rupture. This chapter summarizes the development and progression of atherosclerotic plaques and the contribution of MMPs. We provide data from human studies showing the effect of MMP polymorphisms and the expression of MMPs in both the atherosclerotic plaque and within plasma. We also discuss work in animal models of atherosclerosis that show the effect of gain or loss of function of MMPs. Together, the data provided from these studies illustrate that MMPs are ideal targets as both biomarkers and potential drug therapies for atherosclerosis.

Abstract
Little is known about the impact of the 5A/6A polymorphism of matrix metalloproteinase-3 (MMP-3) on recurrence of atherosclerotic ischemic stroke in Chinese. The aim of this study was to investigate the association of MMP-3 serum level and 5A/6A genetic polymorphism with the recurrence of atherosclerotic ischemic stroke in the Chinese Han population. We analyzed 106 large artery atherosclerosis (LAA) recurrent ischemic stroke patients and 545 LAA first onset ischemic stroke patients from January 2009 to June 2014. Serum MMP-3 concentrations were measured with an enzyme-linked immunosorbent assay. The genotypes of MMP-3 promoter polymorphism (-1171 5A/6A) were determined using polymerase chain reaction-restriction fragment length polymorphism. The frequencies of MMP-3 5A/6A+5A/5A (32.08% vs. 21.47%, p = 0.02) genotype and 5A (16.98% vs. 11.01%, p = 0.01) allele in the recurrent group was significantly higher than those in the first onset group. After adjustment for vascular risk factors, multivariate logistic regression analysis suggested that the MMP-3 5A/6A+5A/5A genotype was an independent risk factor for LAA recurrent ischemic stroke (odds ratio [OR], 1.74; 95% confidence interval [CI], 1.09-2.79, p = 0.021). No significant difference was observed for the MMP-3 serum concentrations between the recurrent group and the first onset group (22.23 ± 8.31 vs. 21.49 ± 7.89 ng/ul, t = 0.88, p = 0.38). The MMP-3 (-1171 5A/6A) polymorphism may contribute to LAA recurrent ischemic stroke susceptibility. Analysis of 5A/6A polymorphism in MMP-3 may identify patients at higher risk for LAA ischemic stroke recurrence, who may be selected for intensive preventive therapy.

Abstract
CONTEXT Matrix metalloproteinases are involved in atherosclerosis and plaque vulnerability. OBJECTIVE To investigate serum levels and genetic polymorphisms of matrix metalloproteinases (MMPs) -1, -3 and -9 in patients submitted to carotid endarterectomy. METHODS Genetic polymorphisms were evaluated using polymerase chain reaction (PCR-RFLP); serum levels were measured using ELISA; histological sections were stained with Picrosirius Red to analyze the fibrous cap thickness, lipid core and collagen content and with hematoxylin--eosin to detect the presence of intraplaque hemorrhage. RESULTS MMP-9 serum levels were significantly higher in patients with a thinner fibrous cap (p = 0.033) or acute or recent intraplaque hemorrhage (p = 0.008) on histology, as well as in patients with previous stroke (p = 0.009) or peripheral vascular disease (p = 0.049). No consistent associations were observed between different MMP genotypes and fibrous cap thickness, lipid core, collagen content or intraplaque hemorrhage. CONCLUSIONS MMP-9 serum levels were consistently associated with markers of carotid atherosclerosis and lesion vulnerability, whereas specific MMP genotypes were not.

Abstract
BACKGROUND Hyperhomocysteinemia was believed to be an independent risk factor for stroke and associate with small vessel disease (SVD) related stroke and large vessel disease (LVD) related stroke differently. However it's still unclear which type of stroke associated with homocysteine (HCY) more strongly because the conclusions of previous studies were contradictory. In this study we focused on the subclinical angiopathies of stroke, i.e., SVD and LVD instead of stroke subtypes and sought to compare the associations between HCY level and different angiopathies. METHODS 324 non-stroke patients were enrolled. Sex, age, HCY level and other vascular risk factors were collected. MRI and angiographies were used to determine the type of angiopathies and their severity, i.e., the scores of leukoaraiosis (LA), plaques and numbers of silent brain infarctions (SBI). LVD was defined as the presence of atherosclerotic plaques of cerebral arteries. SVD was defined as the presence of either LA or SBI. 230 patients were deemed to have LVD; 180 patients were deemed to have SVD. Spearman's correlation test and logistic regression were used to analyze the association between HCY level and different angiopathies. RESULTS The correlation between HCY level and scores of plaques was weaker than that of the scores of LA and numbers of SBI. Hyperhomocysteinemia was an independent risk factor for SVD (OR = 1.315, P <0.001), whereas the association between HCY level and LVD was not that significant (OR = 1.058, P = 0.075). CONCLUSION HCY level associated with SVD more strongly than LVD.

Abstract
MMP-3 is capable of degrading a variety of proteins, including agrin, which plays a critical role in neuromuscular signaling by controlling acetylcholine receptor clustering. High MMP-3 levels in a proportion of myasthenia gravis (MG) patients have been reported. A pathogenic role of MMP-3 in other neurological disorders has been suggested but not proven. We have therefore examined the levels of MMP-3 in 124 MG patients and compared them to 59 multiple sclerosis (MS) patients, 74 epilepsy patients, 33 acute stroke patients, and 90 healthy controls. 15.3% of the patients in the MG group were MMP-3-positive (defined as higher than cutoff value 48 ng/mL) with very high mean MMP-3 concentration (79.9 ng/mL), whereas the proportion of MMP-3 positive patients in the MS (3.4%), epilepsy (6.7%), stroke (0%), and the control group (4.4%) was significantly lower. Mean MMP-3 concentration in the total MG group (25.5 ng/mL) was significantly higher than in the MS (16.6 ng/mL) and stroke (11.7 ng/mL) groups, but did not differ significantly from the epilepsy (19.4 ng/mL) and the control group (23.4 ng/mL). MMP-3 may have a specific pathogenic effect in MG in addition to being associated with autoimmune diseases in general.

Abstract
The BRCA-1 associated protein gene (BRAP) was recently identified as a susceptibility gene for myocardial infarction (MI). In the present study we aimed to decipher the association between the BRAP polymorphism and carotid atherosclerosis and the mechanism underlying its proatherogenic effect. A total of 1749 stroke/MI-free volunteers received carotid ultrasonic examinations for the measurement of intima-medial thickness (IMT) and plaque. The promoter polymorphism rs11066001 was selected because it affects the transcription of BRAP. We found that the GG genotype was associated with a 1.58-fold increased risk for having at least one plaque compared to carrying the A allele (P = 0.021). When subjects were divided by the cutoff value of IMT above the mean plus 1 standard deviation, there was an overrepresentation of the GG genotype in the subjects with thicker IMT (P = 0.004). The expression of BRAP increased significantly when human aortic smooth muscle cells (HASMCs) were treated with lipopolysaccharide (LPS). HASMCs were transfected with small interfering RNA against BRAP or scrambled sequences before treatment with LPS. Knockdown of BRAP led to attenuated HASMC proliferation and reduced secretion of monocyte chemoattractant protein-1 (MCP-1) and interleukin-8 (IL-8) in response to LPS. Downregulation of BRAP did not affect the protein levels of nuclear factor-κB (NF-κB), but prohibited its nuclear translocation. Coimmunoprecipitation experiments confirmed an interaction between BRAP and the two major components of the IKK signalosome, IκBβ and IKKβ. Collectively, BRAP conferred a risk for carotid plaque and IMT. Inflammatory stimuli upregulated BRAP expression, and BRAP activated inflammatory cascades by regulating NF-κB nuclear translocation.
