ABSTRACT Stromelysin-1 (MMP-3) as a key member of metalloproteinase family could have an important role in atherogenesis. The 5A/6A polymorphism in the promoter of MMP-3 gene affects the level of MMP-3 gene expression. We assessed whether the MMP-3 promoter low- and high-activity genotypes are related to susceptibility for carotid atherosclerosis (CA) in Serbian population.
The study group of case-control design consisted of 515 participants. The 265 patients with ultrasonographic evidence of carotid plaque presence were recruited for the study. The 5A/6A polymorphism was typed by RFLP-PCR.
There was significantly higher prevalence of genotypes containing 6A allele in the patients with CA compared to controls (p<0.05). The model of inheritance with the dominant effect of 6A allele gave elevated and significant OR for carotid atherosclerosis (adjusted OR 2.35, CI=1.0-5.5, p=0.048).
Subjects carrying genotypes with 6A allele had significantly higher susceptibility to carotid atherosclerosis.

    ABSTRACT: Atherosclerosis is still the leading cause of death in Western world. Development of atherosclerotic plaque involves accumulation of inflammatory cells, lipids, smooth muscle cells and extracellular matrix proteins in the intima of the vascular wall. Apolipoprotein E participates in the transport of exogenous cholesterol, endogenously synthesized lipids and triglycerides in the organism. Apolipoprotein E gene has been identified as one of the candidate genes for atherosclerosis. Previous studies in different populations have clearly implicated apolipoprotein E genetic variation (E polymorphisms) as a major modulator of low density lipoprotein cholesterol levels. Data considering apolipoprotein E polymorphisms in relation to carotid atherosclerosis gave results that are not in full compliance. The aim of present study was to investigate the apolipoprotein E polymorphisms in association with carotid plaque presence, apolipoprotein E and lipid serum levels in patients with carotid atherosclerosis from Serbia. The study group enrolled 495 participants: 285 controls and 210 consecutive patients with carotid atherosclerosis who underwent carotid endarterectomy. Genotyping of apolipoprotein E polymorphisms were done using polymerase chain reaction and restriction fragment length polymorphism methods. Patients had significantly decreased frequency of the epsilon2 allele compared to controls. Patients who carry at least one epsilon2 allele had a significantly higher level of serum apolipoprotein E and significantly lower low density lipoprotein cholesterol levels compared to those who do not carry this allele. Our results suggest protective effect of apolipoprotein E epsilon2 allele on susceptibility for carotid plaque presence as well as low density lipoprotein cholesterol lowering effect in Serbian patients with carotid atherosclerosis. Further research of multiple gene and environmental factors that contribute to the appearance and the progression of atherosclerosis should be continued with respect to different populations.

    ABSTRACT: 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: Numerous studies have studied the relationships between matrix metalloproteinase (MMP) family gene polymorphisms and ischemic stroke. However, findings remain controversial. The objective of this study was to evaluate the relationships between MMP gene polymorphisms and ischemic stroke by using a meta-analysis. The PubMed, Embase, and Cochrane library databases were systemically searched. Data were extracted by two independent reviewers, and pooled odds ratio (OR) with 95 % confidence interval (CI) were calculated. Eleven studies were enrolled, including a total of 589 cases and 494 controls of MMP-1 -1607 1G/2G; 1,817 cases and 1,731 controls of MMP-3 -1612 5A/6A; and 540 cases and 547 controls of MMP-9 -1562C/T. Under the dominant and recessive models, respectively, the overall ORs and 95 % CIs of -1607 2G were 1.54, 1.16-2.04 (P = 0.005) and 1.25, 0.95-1.65 (P = 0.457); the overall ORs and 95 % CIs of -1612 6A were 1.01, 0.84-1.21 (P = 0.003) and 0.88, 0.75-1.03 (P = 0.057); and the overall ORs and 95 % CIs of -1562T were 0.78, 0.59-1.02 (P = 0.460) and 1.65, 0.73-3.75 (P = 0.340). No publication bias was found in this meta-analysis. This meta-analysis showed that MMP-1 -1607 1G/2G and MMP-3 -1612 5A/6A were risk factors for ischemic stroke, while MMP-9 -1562C/T was not associated with ischemic stroke.
