AB  - Background and Aims: The principal biologic effects of the renin-angiotensin system are mediated by activation of the AT1R receptor. The microRNA miR-155 regulates AT1R expression, with both its, and AT1Rs activity, linked to atherosclerosis. Target sites for miR-155 lie within the 3 UTR of the human AT1R gene, and include the AT1R A1166C polymorphism. Thus far, only levels of circulating miR-155 have been investigated with respect to A1166C genotypes. We hypothesized that the A1166C polymorphism could correlate with different, ultra-sonographically defined plaque phenotypes, as well as with an altered expression of AT1R mRNA and protein in human carotid plaques (CP), and altered expression of miR-155 in patients with advanced atherosclerosis. Methods: Our study cohort comprised 411 patients with advanced carotid atherosclerosis (298 hyperechoic; 113 hypoechoic plaques). PCR analyses identified A1166C genotypes; quantitative real-time PCR determined AT1R and miR-155 expression levels, with AT1R protein expression evaluated by western blot. Results: Genotypes containing the C allele bore a significant association with the hypoechoic plaque phenotype (adjusted OR 1.87, 95% CI 1.16-3.00, p = 0.01). The expression of AT1R mRNA and miR-155 were significantly up-regulated in the CPs of CC genotype carriers compared to the AA/AC genotypes (p = 0.032, p = 0.015, respectively). AT1R protein expression was also significantly higher for CC genotypes (p LT 0.01). Conclusion: Our results indicate that the AT1R A1166C polymorphism impacts an ultrasonographicallydefined human plaque phenotype, with intra-plaque AT1R and miR-155 expression altered in advanced carotid atherosclerosis. Validation and replication of these data should contribute to an improved personalized therapy with which to prevent carotid atherosclerosis. (C) 2016 Elsevier Ireland Ltd. All rights reserved.

AB  - Background: The angiotensin II type 2 receptor (AT2R) - 1332 A/G polymorphism has been denoted as functional and associated with certain cardiovascular disease phenotypes. However, there are no studies considering the association of this gene polymorphism with carotid atherosclerosis (CA) and cerebrovascular events. Therefore, the aim of our study was to investigate a possible association of the AT2R - 1332 A/G polymorphism with the occurrence of carotid plaques (CPs) and history of cerebrovascular insult (CVI) in advanced CA. Methods: The study group included 381 controls and 509 patients with CA consecutively admitted for endarterectomy. Genotyping was determined by polymerase chain reaction-restriction fragment length polymorphism method. The association was analyzed separately for males and females because the AT2R gene is located on the X chromosome. Results: The AT2R - 1332 GG genotype was associated with the advanced CA in the female study group (recessive model of inheritance, AA+AG versus GG; adjusted odds ratio [OR] = 2.25; 95% confidence interval [CI] 1.17-4.33; P=.01). In the male subgroup of patients with CA, the significant overrepresentation of G/- hemizygote was detected in patients with CVI compared to male patients without this event (crude OR = 2.05, 95% CI 1.20-3.50, P=.008). Conclusions: This study suggests a gender-specific association between the AT2R -1332 A/G polymorphism and the occurrence of CP and the history of CVI in advanced CA, but further replication studies are needed.

AB  - Single nucleotide polymorphisms from the chromosome locus 9p21 are reported to carry a risk for various cardiovascular diseases. One of the lead single nucleotide polymorphisms, rs10757278, was mostly investigated in association with coronary artery disease but rarely with carotid atherosclerosis. In this study, we aimed to analyze the association of rs10757278 A/G polymorphism with carotid plaque presence in advanced carotid atherosclerosis. The study included 803 participants, 486 patients with high-grade stenosis ( GT 70%) who were undergoing carotid endarterectomy and 317 controls from Serbian population. Genotypes were determined using the real-time polymerase chain reaction. According to the recessive model of inheritance, GG genotype was significantly and independently associated with carotid plaque in females only (odds ratio 2.42, CI = 1.20-4.90, P = 0.013). Odds ratio was adjusted for age, body mass index, hypertension, TC, LDLC, HDLC and TG, and P value was corrected for multiple comparisons. Our preliminary findings suggest a gender-specific association of rs10757278 polymorphism with carotid plaque. Further studies on larger sample and in genetically and environmentally similar populations are needed.

AB  - BackgroundPrevious research has shown that there is an association between galectin-3 (gal-3) protein and cardiovascular pathology. The aim of this study was to investigate the effects of rs2274273 and rs17128183 on genetic susceptibility to advanced carotid atherosclerosis (CA) and its complications. The rs2274273 has been singled out as the lead SNP of the haplotype block containing LGALS-3 (gal-3 gene) associated with gal-3 circulating levels, while rs17128183 constitutes a potentially functional SNP of the same hap-block. We further sought to determine whether these genetic variants have an impact on the expression of LGALS-3 mRNA in human carotid atherosclerotic plaque tissue. MethodsThe study encompassed 300 control subjects and 485 patients with advanced CA who had undergone carotid endarterectomy. Rs2274273, rs17128183, and LGALS-3 relative mRNA expression was detected by means of real-time PCR (TaqMan((R)) technology). ResultsThere were no statistically significant associations of the investigated genetic variants with susceptibility to advanced CA, nor did we find any associations in terms of ultrasonographically defined plaque phenotypes. The relative expression of LGALS-3 mRNA proved to be significantly higher in carriers of the rare alleles (P=0.039) for both genetic variants. ConclusionOur exploratory results suggest that while rs2274273 and rs17128183 bear no association with the risk of advanced CA or CA-related complications, these genetic variants are likely to affect LGALS-3 expression levels. In order to reach a definitive conclusion on the role played by rs2274273 and rs17128183 in advanced CA, our results should be further validated.

AB  - Aim: Chemokine CXC ligand 16 (CXCL16) has chemoattractive, adhesive and scavenging properties and may play a role in the formation of atherosclerotic lesions. However, studies of CXCL16 polymorphisms in patients with atherosclerosis are scarce. The missense polymorphisms I123T and A181V are potentially important factors in the regulation of presentation and shedding of the CXCL16 chemokine domain. The aim of this study was to analyze the association between I123T and A181V polymorphism haplotypes and the accumulation of carotid plaque as well as the effect of the haplotype on the CXCL16 mRNA expression in carotid plaques in patients with advanced atherosclerosis. Additionally, we performed a bioinformatic prediction analysis of the impact of CXCL16 protein sequence variation on CXCL16-CXCR6 interactions and analyzed the soluble CXCL16 plasma levels according to the CXCL16 haplotype. Methods: This study evaluated a total of 733 participants, including 283 controls and 450 patients with carotid atherosclerosis (CA) undergoing endarterectomy. Analyses of the polymorphisms and the gene expression were performed using real-time PCR. The soluble CXCL16 levels were measured with ELISA. Results: The missense allele haplotype, T123V181, was found to be significantly and independently associated with the occurrence of CA plaque (OR=1.27; 1.02-1.57, p=0.03). This haplotype was predicted to significantly change the CXCL16-CXCR6 interaction, compared to I123A181. Neither the CXCL16 mRNA expression in the human plaques nor the soluble CXCL16 plasma levels differed according to the haplotype. Conclusions: These results indicate that the CXCL16 T123V181 haplotype is a moderate genetic risk factor for the development of carotid plaque. Further functional and replication studies are needed to clarify the mechanisms by which this combination of alleles promotes advanced CA and validate its impact on disease progression.

Additionally, we performed a bioinformatic prediction analysis of the impact of CXCL16 protein sequence variation on CXCL16-CXCR6 interactions and analyzed the soluble CXCL16 plasma levels according to the CXCL16 haplotype. Methods: This study evaluated a total of 733 participants, including 283 controls and 450 patients with carotid atherosclerosis (CA) undergoing endarterectomy. Analyses of the polymorphisms and the gene expression were performed using real-time PCR. The soluble CXCL16 levels were measured with ELISA. Results: The missense allele haplotype, T123V181, was found to be significantly and independently associated with the occurrence of CA plaque (OR=1.27; 1.02-1.57, p=0.03). This haplotype was predicted to significantly change the CXCL16-CXCR6 interaction, compared to I123A181. Neither the CXCL16 mRNA expression in the human plaques nor the soluble CXCL16 plasma levels differed according to the haplotype. Conclusions: These results indicate that the CXCL16 T123V181 haplotype is a moderate genetic risk factor for the development of carotid plaque. Further functional and replication studies are needed to clarify the mechanisms by which this combination of alleles promotes advanced CA and validate its impact on disease progression.",

AB  - Glutathione S-transferases (GSTs) carry out a wide range of functions in cells, such as detoxification of endogenous compounds, removal of reactive oxygen species, and even catalysis of reactions in metabolic pathways beyond detoxification. Based on previous research, GSTM1 and GSTT1 might modify the risk of atherosclerosis. The aim of our study was to analyze the possible association of GSTM1 and GSTT1 gene polymorphisms with the occurrence of carotid plaque (CP); and biochemical parameters of oxidative stress, lipid profile and inflammation, in 346 consecutive patients with advanced atherosclerosis that underwent endarterectomy. A multiplex polymerase chain reaction (PCR) method was used to detect the deletions in GSTM1 and GSTT1 genes in the genomic DNA in 346 patients and 330 controls. The adjusted OR for CP presence (adjusted for age, gender, smoking, hypertension, BMI, HDLC, TG) was 0.24, 95 %CI 0.08-0.7, p LT 0.01 for GSTT1 null and 1.13, 95 %CI 0.62-2.07, p = 0.7 for GSTM1 null genotype. We found significantly lower plasma lipoprotein (a) (Lp(a)) levels in GSTT1 null compared to wild-type genotype carriers in patient group (20.68 +/- A 26.02 mg/dl vs. 40.66 +/- A 42.89 mg/dl, mean +/- A SD, p = 0.04). The serum interleukin-6 (IL-6) values were significantly influenced by both GST polymorphisms in patients with CP. Our results, showing the significant reduction of GSTT1 deletions in patients with CP, suggest involvement of GSTs in carotid atherosclerosis. This study shows additional view of the possible role of GSTs in advanced chronic inflammatory disease of vascular system, but the confirmation in a larger studies in different populations are needed.

AB  - BACKGROUND: To present outcomes following an operative approach of extracranial carotid artery aneurysm (ECAAs) based on anatomic types and associated kinks. METHODS: This study represents retrospective analysis of anatomic type based approach to operative repair of 84 patients with ECAA from 1994 to 2011, 28 (33.3%) with associated kinking. Patients were followed for neurological ischemic events, hematoma, cranial nerve injury, myocardial infarction, neurological, and overall mortality. The results are presented as early, within 30 days after the surgery, and long term during the follow-up. RESULTS: In the early postoperative period, there were no strokes or mortalities, cranial nerve injury rate was 2.4% while 1 patient had myocardial infarction (1.2%). During the follow-up, 4 patients (4.8%) had stroke, out of which 2 patients died (2.3%), while overall mortality was 4.6%. The average 5-year survival rate was 96 +/- 3%. CONCLUSION: Excellent outcomes can be obtained with surgical repair of ECAA, which should be tailored to the anatomic types and presence of kinks. (C) 2014 Elsevier Inc. All rights reserved.

AB  - Introduction: The ACE I/D polymorphism was mostly investigated in association with intima-media thickness, rarely with severe atherosclerotic phenotype. Materials and methods: We investigated the association of I/D polymorphism with severe carotid atherosclerosis (CA) (stenosis GT 70%) in asymptomatic and symptomatic patients undergoing carotid endarterectomy. The 504 patients subjected to endarterectomy and 492 healthy controls from a population in Serbia were investigated as a case-control study. Results: The univariate logistic regression analysis revealed ACE DD as a significant risk factor for severe CA (odds ratio [OR] = 1.3, 95% confidence interval [CI] 1.0-1.7, p = 0.04). After adjustment for the common risk factors (age, hypertension, smoking, and HDL) ACE was no longer significant. However, we found a significant independent influence of DD genotype on plaque presence in a normotensive subgroup of patients (OR 1.8, CI 1.2-3.0, p = 0.01, corrected for multiple testing). In symptomatic patients D allele carriers were significantly more frequent compared with asymptomatic patients (OR 1.6 CI 1.0-2.6, p = 0.05). Conclusions: Our data suggests that ACE I/D is not an independent risk factor for severe CA. On the other hand, a significant independent genetic influence of ACE I/D appeared in normotensive and symptomatic patients with severe CA. This should be considered in further research toward resolving the complex genetic background of severe CA phenotype.

AB  - Objective: Matrix metalloproteinases (MMPs) are involved in the remodeling of the extracellular matrix in the arterial wall. Collagen I is associated with vascular smooth muscle cell (VSMC) migration and monocyte differentiation. MMP-8 is expressed in atherosclerotic plaque and preferentially cleaves collagen type I. The aim of this study was to investigate the associations of two MMP-8 promoter polymorphisms, rs11225395 (-799 C/T) and rs1320632 (-381 A/G), with carotid plaque occurrence, and the influence of these polymorphisms on MMP-8 mRNA expression in plaque tissue. Methods: The study included a total of 766 participants: 277 controls and 489 patients with carotid atherosclerosis undergoing endarterectomy. The two investigated polymorphisms were genotyped by PCR-RFLP. The gene expression analysis was performed by real-time PCR. Results: In females only, a significantly higher frequency of the -381G allele was found in patients with carotid atherosclerosis compared to controls (OR, 1.7; 95% CI 1.1-2.9; p = 0.001). Significant up-regulation of MMP-8 gene expression was observed in patients carrying the -381G allele compared to those with the AA genotype (mean factor, 3.54; SE. range, 0.643-19.551; p = 0.007). Carotid plaque tissue of the haplotype G(-381)T(-799) showed a significantly higher mRNA level compared with the reference A(-381)C(-799) haplotype (p = 0.003). Conclusion: Our preliminary results indicate that MMP-8 -381A/G and -799 C/T gene polymorphisms could be risk factors for carotid atherosclerosis. Further validation and functional studies are needed to establish the potential regulatory role of these polymorphisms and their impact on susceptibility to carotid atherosclerosis.
