Abstract
Tauopathies are a group of neurological disorders, including Alzheimer's disease and frontotemporal dementia, which involve progressive neurodegeneration, cognitive deficits, and aberrant tau protein accumulation. The development of tauopathies cannot currently be stopped or slowed down by treatment measures. Given the significant contribution of tau burden in primary tauopathies and the strong association between pathogenic tau accumulation and cognitive deficits, there has been a lot of interest in creating therapies that can alleviate tau pathology and render neuroprotective effects. Recently, small molecules, immunotherapies, and gene therapy have been used to reduce the pathological tau burden and prevent neurodegeneration in animal models of tauopathies. However, the major pitfall of the current therapeutic approach is the difficulty of drugs and gene-targeting modalities to cross the blood-brain barrier and their unintended side effects. In this review, the current therapeutic strategies used for tauopathies including the use of oligonucleotide-based gene therapy approaches that have shown a promising result for the treatment of tauopathies and Alzheimer's disease in preclinical animal models, have been discussed.

Abstract
PURPOSE We aimed to study insertion/deletion (I/D) variation (rs4646994) of ACE gene in a group of SLE patients in west of Iran and its possible relationship with oxidative stress. METHOD AND RESULTS Genotypes and allele frequencies related to ACE (I/D) variation were determined in 108 SLE patients and 110 gender and age-matched healthy controls using PCR. Neopterin, malondialdehyde (MDA), and serum lipid concentrations were determined by HPLC and enzyme assay respectively. The overall distribution of ACE I/D genotypes in SLE patients was different from that of the control group (P = 0.005). DD genotype compared to ID genotype increased the risk of SLE (OR = 2.57, 95% CI 1.4-4.8, P = 0.003). ID genotype compared to the II genotype decreased the risk of disease (OR = 0.45, 95% CI 0.2-0.99, p = 0.042). SLE patients with DD, ID, and II genotypes had lower paraoxonase (PON) activity and higher serum levels of MDA and neopterin versus control patients. We also detected a significant protective effect against SLE in presence of ACE I alleles and lack of angiotensin II receptor, type 1 (AGTR1) A1166C (NCBI reference SNP id: rs5186), C alleles in this study (OR = 0.31, 95% CI 0.14-0.68, P = 0.002). CONCLUSIONS Carriers of the DD genotype of ACE gene with higher serum concentrations of neopterin and MDA, and lower PON activity had a high risk to develop SLE, while ID genotype decreased the risk of disease development by 2.22 times compared to II genotype.

Abstract
Caveolin-1(cav-1) is overexpressed in prostate cancer (PC) and is associated with progression of the disease. We investigated the effects of CAV1-T29107A and endothelial nitric oxide synthase (eNOS) G894T polymorphisms on the serum levels of testosterone, NO and prostate-specific antigen (PSA) in patients with PC. We genotyped cav-1 and eNOS genes in 112 PC patients and 150 healthy controls by PCR-RFLP. Serum levels of NO 2 - and NO 3 - were measured using spectrophotometry, and serum levels of testosterone and PSA were measured by ELISA. The frequencies of CAV1 genotypes A/T vs. A/A according to the dominant model AT + TT vs. AA genotype and T allele were significantly higher in PC patients in comparison with the control group and considerably increased the risk of disease by 2.19-, 1.44- and 1.6-fold, respectively. AT + TT genotypes were associated significantly with the increased risk of PC in those with smoking or diabetes by 3.08-fold (P = .004). Individuals carrying concurrently the T allele of CAV1 A29107T and the T allele of eNOS G894T genes had a significantly increased risk of PC by 2.52-fold (P = .009). We did not find any significant relationship between eNOS G894T genotypes and alleles with susceptibility to PC. Our results highlighted the significance of CAV1-T29107A SNP but not (eNOS) G894T in the susceptibility to PC in our the population that we have studied.

Abstract
As a promising strategy in overcoming drug resistance, the nano drug co-delivery system (NDCDS) can transport two or more drugs into the cell. In this study, we sought to compare the dual and single drug-delivery system, to deliver the optimal dose of Resveratrol (RES) and Tretinoin (TTN) into the in vitro matured oocyte and morula-compact stage embryonic cells. The formation of single (RES/TTN) and dual-drug (RES + TTN)-SLN were confirmed by Uv-vis spectrophotometery, dynamic light scattering (DLS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) technologies. In two experiments, the oocytes/presumptive zygotes were cultured under various concentrations of the single (RES/TTN) and dual-drug (RES + TTN)-SLN. In vitro toxicity studies, including nuclear staining (Aceto-orcein and Hoechst 33342), H2DCFDA fluorescent staining, chemiluminescence assay, and quantitative reverse transcription-PCR (qRT-PCR) techniques, indicated an excellent oocyte/embryo internalization of RES and TTN. Moreover, when oocytes/embryos were treated with the lowest concentration of RES + TTN-SLN, antioxidants-related genes were upregulated, apoptotic-related genes were downregulated, and intra/extracellular ROS production was reduced. In vitro cytotoxicity studies also demonstrated that single/dual-encapsulation of RES or TTN were safe even at the highest concentration (10 and 5 μM) compared to the control group. To sum it up, both delivery systems of RES and TTN by SLN (dual or single encapsulation) can deliver the optimal dose of RES and TTN into the oocyte/embryo. Where the dual-delivery of RES and TTN even at the lowest concentration (0.25 μM + 0.1 μm) showed a synergistic anti-oxidative effect in oocyte/embryo with a better inhibition of intra/extra-cellular ROS production by an enhanced/controlled intracellular penetration.

Abstract
The blood–brain barrier (BBB) is a natural obstacle for drug delivery into the human brain, hindering treatment of central nervous system (CNS) disorders such as acute ischemic stroke, brain tumors, and human immunodeficiency virus (HIV)-1-associated neurocognitive disorders. Poly(lactic-co-glycolic acid) (PLGA) is a biocompatible polymer that is used in Food and Drug Administration (FDA)-approved pharmaceutical products and medical devices. PLGA nanoparticles (NPs) have been reported to improve drug penetration across the BBB both in vitro and in vivo. Poly(ethylene glycol) (PEG), poly(vinyl alcohol) (PVA), and poloxamer (Pluronic) are widely used as excipients to further improve the stability and effectiveness of PLGA formulations. Peptides and other linkers can be attached on the surface of PLGA to provide targeting delivery. With the newly published guidance from the FDA and the progress of current Good Manufacturing Practice (cGMP) technologies, manufacturing PLGA NP-based drug products can be achieved with higher efficiency, larger quantity, and better quality. The translation from bench to bed is feasible with proper research, concurrent development, quality control, and regulatory assurance.

Abstract
Background Reactive oxygen species (ROS) play a crucial role in etiology of DNA fragmentation and lipid peroxi-
dation in sperm, leading to infertility in men. The silent information regulators SIRT1 and SIRT3 are members of the
sirtuins protein family known to be involved in cancer genetics, aging and oxidative stress responses. The aim ofthis
study is to determine the correlation between SIRT1 and SIRT3 with antioxidants, oxidative stress biomarkers, and
DNA fragmentation in the semen of asthenoteratozoospermic and normozoospermic men. Materials and Methods In this case-control study, after spermogram analysis the specimens were divided into
two groups, normozospermic (n=40) and asthenoteratozoospermic (n=40), according to World Health Organization
(WHO) standards. Sperm DNA fragmentation was evaluatedusing the sperm chromatin dispersion (SCD) test.Catalase
activity was measured using the Aebi spectrophotometeric method. Total antioxidant capacity (TAC) level and super-
oxide dismutase (SOD) activitywere measured by using commercially available colorimetric assays. Enzyme-linked
immune sorbent assay (ELISA) was used to measure SIRT1 and SIRT3 protein levels of seminal plasma. Malondial-
dehyde (MDA) level in seminal plasma was determined by high-performance liquid chromatography (HPLC). Results The asthenoteratozoospermic group had significantly lower catalase and SOD activities and TAC levels in
comparison with the normozoospermic group (P<0.001).The percentage of DNA fragmentation and MDA level in the
asthenoteratozoospermic group were remarkably higher than in the normozoospermic group. The SIRT1 and SIRT3
protein levels in seminal plasmawere remarkably lower in asthenoteratozoospermic group than the normozoospermic
group (P<0.001). Conclusion The results of this study suggest that SIRT1 and SIRT3 protein levels are negatively correlated with
oxidative stress and DNA fragmentation in semen. The low levels of SIRT1 and SIRT3 in asthenoteratozoospermic
men may lead to an increase in oxidative stress, DNA fragmentation, and lipid peroxidation that eventually result in
immotile and immature spermatozoa (asthenoteratozoospermia).

Abstract
Matrix metalloproteinases (MMPs) are a group of zinc dependent enzymes that are involved in tumor cell invasion and metastasis. The role of MMP-2 and -9 genetic polymorphism in different malignancies has been the subject of numerous studies. The present research has attempted to discover any positive correlation between MMP-2 and MMP-9 SNPs and prostate cancer (PCa) in patients with a history of either diabetes or smoking habits. 112 PCa-patients and 150 unrelated healthy-controls that matched for age and sex were selected for present case-control study. MMP-2 -1575G/A and MMP-9 -1562 C/T polymorphisms detected by PCR-RFLP, serum tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2), testosterone, prostate-specific antigen (PSA), free-prostate-specific-antigen (fPSA), and fPSA/PSA levels were detected by ELISA and enzyme assay, respectively. MMP-2 and MMP-9 activities were measured by gelatin-zymography. Covariates were considered as age, status of cigarette smoking, and a possible history of diabetes mellitus (DM). The frequency of -1575 MMP-2 A/A + A/G and -1562 MMP-9 C/T + T/T genotypes were higher in PCa-patients with DM (74.3%,p = 0.003) and with smoking habits (72.5%,p = 0.005). These genotypes were associated with the increased risk of prostate cancer in smokers (3.52-folds) and in individuals with history of DM (4.34-folds). A significant positive association was found between level of TIMPs (TIMP -1 and TIMP-2) and BMI in PCa-patients and also between testosterone levels and MMP-9 activity in healthy control subjects. For the first time, this study demonstrated that activities of MMP-2 -1575G/A and MMP-9 -1562C/T variants in association with smoking and diabetes are considered significant risk factors for PCa.

Two hundred forty-nine individuals with cardiovascular disease (92 with aortic and Mitral Valves Calcification (AMVC) and 157 with Coronary Artery Diseases (CAD) that their diseases were confirmed by echocardiography and angiography and unrelated 182 healthy controls (gender and age-matched) were selected for this case-control study. The VDR 1544410G>A, and VDBP 7041T>G genotyping were detected by PCR-RFLP, serum vitamin D and lipid concentrations were measured by ELISA and enzyme assay, respectively. The VDR rs1544410G>A gene is a strong risk factor for CAD (OR = 1.28, p = 0.002) and the dominant genotype (T/G+G/G) of VDBP 7041 T>G SNP plays a protective role (OR = 0.67, p = 0.003) in AMVC development in studied population. In addition, lower level of vitamin D strongly increased the risk of CAD (15 ± 11.02 vs. 21.3 ± 18 μg/L, p = 0.043) and AMVC (12.1 ± 13.1 vs.21.3 ± 18 μg/L, p = 0.014) development in individuals carrying T/T genotype of VDBP 7041 T>G gene polymorphism. There was a strong interaction between A allele VDR rs1544410 and G allele of VDBP rs7041 genes in a protective role (OR = 0.74, p = 0.044) in AMVC patients). CAD and AMVC patients were deficient in vitamin D, i.e. their level of vitamin D was strongly lower than that in the control group. Our findings for the first time indicated that there is a strong association between vitamin D deficiency, lipid profile and the VDR rs1544410G>A and rs7T41>G VDBP genes polymorphisms. These interactions may be one of the important factors for CAD and AMVC incidence.

Abstract
Psoriasis is a chronic inflammatory skin condition and angiotensin-converting enzyme (ACE) is a key circulating enzyme converting angiotensin (Ang) I to the vasoactive peptide Ang II. The exact role of ACE insertion (I)/deletion (D) polymorphism (rs106180) in psoriasis is not clear. We aimed to examine whether the ACE I/D and Ang II type 1 receptor (AT1R) A1166 C-polymorphisms (rs106165), lipid profile, and stress oxidative are associated with susceptibility to psoriasis. One hundred patients with psoriasis and 100 sex- and age-matched unrelated healthy controls were recruited for this case-control study. ACE I/D and AT1R A1166 C polymorphisms were identified by the polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism, respectively, malondialdehyde (MDA) was detected by the high-performance liquid chromatography, serum arylesterase (ARE) activity of paraoxonase and catalase activities were detected by the spectrophotometry, superoxide dismutase (SOD) activity and vascular adhesion protein (VAP)-1 were measured by ELISA. The presence of C allele of AT1R A1166 C and I allele of ACE considerably increased the risk of psoriasis by 6.42-fold (P < 0.001). The distribution of II-genotype of ACE was significantly higher in psoriasis patients than in control group and increased the risk of disease by 3.11-times (P = 0.023). The higher levels of MDA in patients and the higher activity of SOD, ARE, and CAT was observed in healthy controls with I/D+I/I-genotype of ACE I/D. This study for the first time demonstrated that the ACE I/D and AT1R A 1166 C genes polymorphisms robustly increases the risk of developing psoriasis in population from west of Iran. In addition, these individuals had significantly higher VAP-1 and MDA concentration and lower enzymatic and nonenzymatic antioxidant-status, suggesting that psoriatic patients carrying C allele of AT1R1166 polymorphism may be more susceptible to cardiovascular disease and myocardial infarction compared with A allele.

Abstract
BACKGROUND Discovering the association between genetic variations of metabolizing enzymes with idiopathic diseases such as ulcerative colitis (UC) may not only be an auxiliary agent in diagnosis but also could be an effective pharmacotherapy for inflammatory bowel disease (IBD). The aim of the present case-control study was to determine the association of cytochrome P450 2D6 (CYP2D6 *4), N-acteyltransferase-2 (NAT2*7) and multidrug resistance 1 (MDR1) 3435 C/T genotypes with UC susceptibility and thiopurine methyltransferase (TPMT) enzyme activity. METHODS TPMT activity was measured by high performance liquid chromatography (HPLC) and genotypes for the 3 mentioned polymorphisms were determined in 215 unrelated UC patients and 212 unrelated healthy controls by polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) in a Kurdish population from Iran. RESULTS CYP2D6*4 A allele, NAT2*7 A and MDR1 3435 C/T alleles act synergistically to increase the risk of UC by 3.49 times. The frequency of the A allele of CYP2D6*4 was significantly higher in UC patients (12.6%) compared to control subjects (8.5%, P = 0.046) that significantly increased the risk of UC by 1.56-fold (P = 0.047). The frequencies of NAT2*7 genotypes and alleles were similar in both studied groups. CONCLUSION The most important outcome of this study is that for the first time we demonstrated the simultaneous presence of TMDR1, A CYP2D6*4 and A NAT2*7 alleles robustly increased the risk of developing UC by 3.49-fold. The current study suggests that CYP2D6*4 and MDR1 3435 C/T gene polymorphisms may be risk factors for UC susceptibility.

Abstract
BACKGROUND Thiopurine methyl transferase (TPMT), a drug-metabolizing enzyme, catalyzes methylation and consequently, the metabolism of thiopurine compounds used for treatment of inflammatory bowel disease (IBD). Individuals who are homozygous recessive or have extremely low TPMT activity need to avoid thiopurines because of concern for significant leukopenia. The aim of this research was to determine TPMT phenotypes and genotypes in IBD patients to predict the risk of thiopurine toxicity before treatment. METHODS The present case-control study consisted of 210 ulcerative colitis patients and 212 unrelated healthy controls from the population of western Iran. TPMT phenotype and genotype were determined by HPLC and allele specific PCR and PCR-RFLP, respectively. RESULTS TPMT phenotyping and genotyping were compatible and demonstrated no frequency for deficient, 2.2% for low, and 97.8% for normal-activity which is different compared with the results of other studies. There was a significant negative correlation between TPMT activities as calculated based on nmol6MTG/gHb/h and the Hb levels in both UC (r = -0.54, p < 0.001) and control groups (r = -0.27, p < 0.001). Interestingly, a significant positive correlation between Hb levels and TPMT activities was seen when the enzyme activity was calculated in mU/L in both UC patients (r = 0.14, p = 0.05) and in control subjects (r = 0.43, p < 0.001). The overall concordance rate between TPMT phenotypes and genotypes of mutants to alleles (9 out of 422), based on receiver-operating characteristic (ROC) curve, yielded a sensitivity of 94.7% and specificity of 90% for mU/L and a sensitivity of 85.6% and specificity of 90% for nmol6MTG/gHb/h. CONCLUSIONS The use of mU/L is more appropriate than nmol6MTG/gHb/h for expressing TPMT activity, and there is better correlation between genotypes and phenotypes of TPMT based on mU/L. The frequency of known mutant TPMT alleles in western Iran (Kurd population) is low suggesting low risk of thiopurine drug toxicity in IBD patients from this region.

Abstract
Evidences indicate that abnormal lipid metabolism and lipid peroxidation can affect the progression of complications in systemic lupus erythematosus (SLE) patients. Apolipoprotein E (ApoE) and paraoxonase-1 (PON1) play important role in lipid metabolism and protection of lipid peroxidation. The polymorphisms of ApoE and paraoxonase (PON1) L55M (Met < Leu) allele genes lead to disorders in lipid metabolism and are related to atherosclerosis. This study is the first investigation to examine the possible association between ApoE and PON1-L55M polymorphisms and correlation with serum arylesterase (ARE) activities of PON, levels of malondialdehyde (MDA), neopterin, and lipid lipoprotein in SLE patients from Iranian western population. The present case-control study consisted of 107 SLE patients and 101 gender- and age-matched, unrelated, healthy controls from Iran's western population. The ApoE and PON1-L55M genotypes were identified using PCR-RFLP method. The serum level of MDA, neopterin, lipid levels, and ARE activity were determined by HPLC, commercial kits, and spectrophotometry, respectively. Our results showed that ApoE ε4 and PON1-55M alleles act synergistically to increase the risk of SLE by 1.47 times (p = 0.038). We found that the frequency of ApoE Ɛ3/Ɛ4 genotype was higher in SLE patients (11.2%) compared with control subjects (5%), although the difference was not significant (p = 0.087). This study for the first time not only demonstrates that ApoE Ɛ4 and PON-55M alleles synergistically increase the risk of SLE but also reveals that serum levels of MDA, neopterin, and LDL-C are high in SLE patients. This information may be in value for evaluating SLE progression and in the elucidation of the mechanisms of the disease pathogenesis.

Abstract
BACKGROUND Abnormal expression and different splicing of miRNAs are involved in several human inflammatory disorders. It has been suggested that gene variants of miRNAs may be associated with increased risk of ulcerative colitis (UC). We aimed to evaluate the association of two SNPs (miRNA-A-499G(rs3746444) and miRNA-T196a2C(rs11614913)) with the risk of UC and monitor their effect on thiopurine-S-methyltransferase (TPMT) activity in Kurdish population of Iran. METHODS This case-control study was performed on 210 UC patients and 212 healthy individuals. Genotyping assay was performed using PCR-RFLP and the TPMT-activity was measured via non-extraction-HPLC method. RESULTS We found that the existence of GG genotypes and G allele of miRNA-A-499G SNPs significantly increased the risk of UC by 1.76 and 1.32 times, respectively. The distribution of GG genotype (23.8% vs. 16%, χ2 = 4.2, p = 0.041) and G allele (46.4% vs. 39.4%, χ2 = 4, p = 0.046) of miRNA-A-499G, were significantly higher in UC patients compared to control group. Our results indicate that miRNA SNPs (miRNA-T-196a2C and miRNA-A-499G) have no significant effect on TPMT activity of studied population. CONCLUSIONS Our results, for the first time, demonstrate that the GG genotype and G allele of miRNA-A-499G significantly increase the risk of UC. However, miRNA SNPs showed no significant effect on TPMT activity in studied population.

Abstract
BACKGROUND AND PURPOSE Intracerebral hemorrhage (ICH) is a devastating cerebrovascular disorder with high morbidity and mortality. Minocycline is a matrix metalloproteinase-9 (MMP-9) inhibitor that may attenuate secondary mechanisms of injury in ICH. The feasibility and safety of minocycline in ICH patients were evaluated in a pilot, double-blinded, placebo-controlled randomized clinical trial. METHODS Patients with acute onset (<12 h from symptom onset) ICH and small initial hematoma volume (<30 ml) were randomized to high-dose (10 mg/kg) intravenous minocycline or placebo. The outcome events included adverse events, change in serial National Institutes of Health Stroke Scale score assessments, hematoma volume and MMP-9 measurements, 3-month functional outcome (modified Rankin score) and mortality. RESULTS A total of 20 patients were randomized to minocycline (n = 10) or placebo (n = 10). The two groups did not differ in terms of baseline characteristics. No serious adverse events or complications were noted with minocycline infusion. The two groups did not differ in any of the clinical and radiological outcomes. Day 5 serum MMP-9 levels tended to be lower in the minocycline group (372 ± 216 ng/ml vs. 472 ± 235 ng/ml; P = 0.052). Multiple linear regression analysis showed that minocycline was associated with a 217.65 (95% confidence interval -425.21 to -10.10, P = 0.041) decrease in MMP-9 levels between days 1 and 5. CONCLUSIONS High-dose intravenous minocycline can be safely administered to patients with ICH. Larger randomized clinical trials evaluating the efficacy of minocycline and MMP-9 inhibition in ICH patients are required.

Abstract
Thiopurine drugs remain pivotal therapies for the wide varieties of diseases such as inflammatory bowel disease (IBD). Here, thiopurine S-methyltransferase (TPMT) phenotype, the main metabolizing enzyme of thiopurine-drugs, was studied. This is for the first time that TPMT activity is measured in Iranian IBD patients. We used an improved direct liquid chromatography assay without need for solvent extraction and minimize excess labor handling making it ideal for use in routine referral medical centers. TPMT activity in whole blood was determined by a non-extraction HPLC method. We evaluated 427 individuals including 215 IBD patients and 212 unrelated healthy individuals as control group from Iran's western population. TPMT phenotyping of this study demonstrated no frequency for deficient, 2.8 % for low and 97.2% for normal activity, which is different with results of other studies. There was a significant negative correlation between TPMT activities as calculated based on nmol/grHb/h and the Hb-levels in IBD and control groups (r= -0.54, P<0.001 and r= -0.27, P<0.001), respectively. Interestingly a significant positive correlation between Hb levels and TPMT-activities were seen when the activity calculated in mU/L in IBD patients and control subjects (r=0.14, P=0.05 and r=0.43, P<0.001), respectively. We strongly suggest the use of international unit (mU/L) is more appropriate than nmol6MTG/grHb/h for expressing TPMT-activity in IBD patients. In addition, in comparison with other providers of TPMT test activity and centers around the world the risk of toxicity is much lower after utilizing thiopurine drugs for IBD patients in this region.

Angiotensin II, one of the rennin–angiotensin system components, is important in the cardiovascular hemodynamic and plays an important role in the development of cardiovascular disease in systemic lupus erythematosus (SLE) patients. The angiotensin II, through interaction with angiotensin II type 1 receptor (AGTR1), promotes proliferation, inflammation and fibrosis. The single nucleotide polymorphism of the AGTR1 (dbSNP: rs5186) gene can be associated with development and progression of SLE disease. The aims of this study were to compare the frequency of AGTR1 rs5186 in SLE patients with healthy individuals and to evaluate possible association between AGTR1 A1166C gene polymorphism and serum level of lipids, neopterin and malondialdehyde in SLE patients from a population of West Iran. One hundred SLE patients and 98 healthy subjects were studied. The AGTR1 A1166C polymorphism was detected by polymerase chain reaction– restriction fragment length polymorphism method and the serum lipid profile was obtained by enzymatic method. Neopterin and malondialdehyde were detected using high-performance liquid chromatography. We did not detect significant association between AGTR1 A1166C polymorphism and the risk of SLE. The levels of triglyceride (225 ± 118 mg/dl), neopterin (30 ± 24 nmol/l) and malondialdehyde (25 ± 9.6 nmol/l) in SLE patients were significantly higher than those in control subjects (139 ± 56 mg/dl, p = 0.03, 6.4 ± 2, p = 0.03, 9.4 ± 2.5 nmol/l, p = 0.01, respectively). Individuals with AGTR1 AC + CC genotype had higher levels of total cholesterol and malondialdehyde compared with those with AGTR1 AA genotype. SLE patients with either AGTR1 AA or AGTR1AC + CC genotype had significantly higher malondialdehyde or neopterin levels compared with the corresponding control subjects. In conclusion, although the present study did not find any association between AGTR1 A1166C polymorphism and the risk of SLE, the presence of this polymorphism was associated with higher levels of malondialdehyde and higher concentration of neopterin in patients.

Abstract
The cytotoxic T lymphocyte antigen-4 (CTLA-4) also known as CD152 (cluster of differentiation 152) is a crucial negative regulator of the immune system. This protein receptor provides negative signals in order to suppress T-cell activation and immune attack against self-antigens, although its role is unclear. The ability of CTLA-4 to limit T cell-mediated immune response has made it a major target in treatment of tumors and autoimmune diseases such as systemic lupus erythematosus (SLE). In this study, we investigated whether CTLA-4 G-1661A and CTLA-4 T-1722C mutations are associated with SLE. So one hundred nine SLE patients and 101 gender and age-matched unrelated healthy controls were recruited for this case-control study. The promoter mutations were detected by PCR-RFLP, neopterin, malondialdehyde (MDA) and serum lipid concentration were determined by HPLC and enzyme assay, respectively. RESULT We found that both codominant (AA vs. GG) and recessive (AA vs. GA+GG) CTLA-4 G-1661A mutation significantly decreased the risk of SLE by 1.7 and 3.7 times, respectively. Interestingly, SLE patients with AA genotypes of CTLA-4 G-1661A have lower neopterin and MDA concentration compared with GA+GG genotypes. The overall distribution of CTLA-4 T-1722C genotypes and alleles in SLE patients were similar to those in control group. In conclusion, our findings showed, that there is an association between systemic inflammatory markers, oxidative stress and the CTLA-4 G-1661A GG+AG genotypes, MDA and neopterin which are the most conventional risk factors for coronary heart disease, therefore these mutations may be consider as a risk factor for susceptibility to heart disease in SLE patients.

Abstract
Stroke remains the fifth leading cause of mortality in the United States with an annual rate of over 128,000 deaths per year. Differences in incidence, pathogenesis, and clinical outcome have long been noted when comparing ischemic stroke among different ethnicities. The observation that racial disparities exist in clinical outcomes after stroke has resulted in genetic studies focusing on specific polymorphisms. Some studies have focused on matrix metalloproteinases (MMPs). MMPs are a ubiquitous group of proteins with extensive roles that include extracellular matrix remodeling and blood-brain barrier disruption. MMPs play an important role in ischemic stroke pathophysiology and clinical outcome. This review will evaluate the evidence for associations between polymorphisms in MMP-1, 2, 3, 9, and 12 with ischemic stroke incidence, pathophysiology, and clinical outcome. The role of polymorphisms in MMP genes may influence the presentation of ischemic stroke and be influenced by racial and ethnic background. However, contradictory evidence for the role of MMP polymorphisms does exist in the literature, and further studies will be necessary to consolidate our understanding of these multi-faceted proteins.

Abstract
Inflammatory bowel disease(IBD) is progressing rapidly in developing countries such as Iran. This research is intended to compile the frequency distribution of the drug metabolizing enzyme, thiopurine methyl transferase(TPMT) and the drug transporter, Multi drug resistance(MDR1) which are involved in metabolism of many therapeutics such as thiopurines in inflammatory bowel disease(IBD). Ethnicity is an important variable influencing drug response. The aims of this research were to investigate the association of TPMT phenotypes with MDR1 genotypes. TPMT activity was measured by using a non-extraction HPLC method and genotype for the C3435T polymorphism of MDR1 gene was determined in 215 unrelated IBD patients including of 85 males and 130 females and 212 unrelated healthy individuals consisted of 96 males and 116 females as control group by PCR-RFLP in Iran's western population. TPMT phenotypes demonstrated no frequency for deficient, 2.2% for low and 97.8% for normal activity that is different with results of other studies. Interestingly there were a significant negative correlation between TPMT activities as calculated based on nmol/grHb/h and positive correlation calculated in mU/L with Hb levels in IBD patients and control subjects. Dominant and codominant MDR1 C3435T gene polymorphism increased the risk of IBD by 1.45 and 1.46 times, respectively. IBD patients with MDR1 mutant genotypes C3435T, had lower TPMT activites and Hb concentrations. Using of mU/L is more appropriate than nmol6MTG/grHb/h for expressing TPMT activity. TPMT frequency of deficient and low activity in western Iran is low. The carriers of mutant C3435T MDR1 are not good TPMT methylators.

Abstract
Adropin is a 4.9 kDa peptide that is important for maintenance of metabolic and non-metabolic homeostasis. It regulates glucose and fatty acid metabolism and is involved in endothelial cell function and endothelial nitric oxide (NO) synthase bioactivity as well as physical activity and motor coordination. Adropin is expressed in many tissues and organs including central nervous system (CNS). This peptide plays a crucial role in the development of various CNS disorders such as stroke, schizophrenia, bipolar disorder as well as Alzheimer's, Parkinson's, and Huntington's diseases. In this comprehensive review, the potential roles of adropin in cellular signaling pathways that lead to pathogenesis and/or treatment of CNS disorders will be discussed.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease that involves multiple organs and is characterized by persistent systemic inflammation. Among the effects of inflammatory mediators, the induction of matrix metalloproteinases-2 and -9 (MMP-2 and MMP-9) and oxidative stress has been demonstrated to be important in the development of SLE. In this study, the possible association between MMP-9 and MMP-2 functional promoter polymorphism, stress, and inflammatory markers with development of severe cardiovascular disease (CVD), high blood pressure (HBP), and lupus nephropathy (LN) in SLE patients was investigated. The present case-control study consisted of 109 SLE patients with and without CVD, HBP and LN and 101 gender- and age-matched unrelated healthy controls from a population in western Iran. MMP-2 –G1575A and MMP-9 –C1562T polymorphisms were detected by PCR-RFLP, serum MMP-2 and MMP-9, neopterin, malondialdehyde (MDA) and lipid levels were determined by ELISA, HPLC and enzyme assay, respectively. We found that MMP-9 –C1562 T and MMP-2 –G1575A alleles act synergistically to increase the risk of SLE by 2.98 times ( p = 0.015). Findings of this study also demonstrated that there is a significant increase in the serum levels of MMP-2, neopterin and MDA and a significant decrease in serum level of MMP-9 in the presence of MMP-9-C1562 T and MMP-2 –G1575A alleles in SLE patients compared to controls. Further, SLE patients with MMP-9 (C/T + T/T) genotype had significantly higher serum concentrations of MMP-2, neopterin, MDA and LDL-C, but lower serum MMP-9 and HDL-C levels than corresponding members of the control group. MMP-9 (C/T + T/T) genotype increased risk of hypertension in SLE patients 2.71-fold. This study for the first time not only suggests that MMP-9 –C1562 T and MMP-2 –G1575A alleles synergistically increase the risk of SLE but also high serum levels of MDA, neopterin, and circulatory levels of MMP-2 and lower MMP-9 in SLE patients. This information may be important in the evaluation of SLE progression and in the elucidation of the mechanisms of the disease pathogenesis.

Abstract
There is some evidence indicating lipid peroxidation can affect progression of atherosclerosis, cardiovascular diseases (CVDs) and glomerulonephritis in systemic lupus erythematosus (SLE) patients. Human butyrylcholinesterase (BuChE) and paraoxonase-1 (PON1) are two major bioscavenger enzymes that are associated with inflammation, oxidative stress and lipid metabolism. Hyperlipidemia, increase in lipid oxidation reactions and defects in antioxidant status may lead to increased oxidative stress and high frequency of CVDs in SLE. It has also been suggested that deficiency in the function of the antioxidant system and an increase in reactive oxygen release (ROS) may play an important role in the pathogenesis of SLE. This study is the first investigation to examine the association of BuChE phenotypes, PON1 (L55M; PON-55-M) polymorphism, the levels of malondialdehyde (MDA), neopterin, lipid-lipoprotein and activities of BuChE and arylesterase activity (ARE) of PON with severity of SLE. The present case-control study consisted of 109 SLE patients and 101 gender- and age-matched, unrelated healthy control subjects from the population of west Iran. We found that the PON-55-M allele and BuChE non-UU act synergistically to increase the risk of SLE by 2.5 times (1.03–6.7, p = 0.044). There was a significant negative correlation between severity of SLE with serum BuChE activity ( R = −0.31, p < 0.001) and positive correlation with serum neopterin level. The SLE patients with the PON-55-M (M/L + M/M) allele or with BuChE non-UU phenotype had significantly lower serum ARE and BuChE activities than those with PON-55-L/L or BuChE-UU phenotypes, respectively. In addition, their serum levels of MDA, neopterin and LDL-C were significantly elevated, suggesting that these individuals are more susceptible to CVD. However, further studies are needed to shed more light on the contribution of the M allele of PON1 and non-UU phenotypes of BuChE in the development of SLE in different ethnicities.

Abstract
Catalytic oligonucleotides, known as DNAzymes, are a new class of nucleic acid-based gene therapy that have recently been used in preclinical animal studies to treat various cancers. In this study the systemic distribution, pharmacokinetics, and safety of intravenously administered anti-MMP (matrix metalloproteinase)-9 DNAzyme (AM9D) were determined in healthy FVB and in MMTV-polyoma virus middle T (PyMT) transgenic mice bearing mammary tumors. MMP-9 is known to be involved in tumor cell development, angiogenesis, invasion, and metastasis. Sulfur-35 ((35)S) labeled ([(35)S]-AM9D) administered intravenously, without the use of carrier molecules, to healthy and mammary tumor bearing MMTV-PyMT transgenic mice distributed to all major organs. The order of percentages of [(35)S]-AM9D accumulation in different organs of healthy and MMTV-PyMT mice were blood>liver>kidney>lung>spleen>heart and mammary tumor>blood≈liver>kidney>spleen>lung>heart, respectively. The amount of AM9D accumulated in mammary tumors 2 hours post injection was 0.6% and 0.2% higher than in either blood or liver, respectively, and its rate of initial clearance from mammary tissue was at least 50% slower than the other organs. Approximately 43% of the delivered dosage of [(35)S]-AM9D was cleared from the system via feces and urine over a period of 72 hours. No evidence of acute or chronic cytotoxicity, local or widespread, associated with AM9D treatment (up to 75 mg AM9D /kg of body weight) was observed in the organs examined. These data suggest that DNAzyme in general and AM9D in particular can be used systemically as a therapeutic agent to treat patients with breast cancer or other metastatic and surgically inaccessible tumors.

Abstract
Paraoxonase-1 (PON1) is a serum HDL-bound enzyme that hydrolyzes a number of aromatic carboxylic acid esters including lipid peroxides, preventing LDL oxidation. Systemic lupus erythematosus (SLE) patients are at greater risk of oxidative stress, which is associated with abnormal plasma lipid metabolism. In this study, association of PON-55 polymorphism with serum arylesterase (ARE) activities, malondialdehyde (MDA), neopterin, lipids and lipoproteins levels in SLE patients and the development of hypertension was investigated. The present case-control study consisted of 109 SLE patients with and without high blood pressure (BP) and 103 healthy controls from the population in the west of Iran. PON-55 Met<Leu polymorphism was detected by restriction fragment length polymorphism (PCR-RFLP), serum ARE activity, MDA, neoptrin, lipid and apolipoprotein levels were determined by spectrophotometery and HPLC and enzyme assay, respectively. The presence of PON-55 M/M genotype was found to be associated with SLE and the development of high BP. The SLE patients with PON-M (M/L+M/M) allele had significantly lower serum ARE activity, but higher neoptrin and LDL-C than the carriers of corresponding genotypes in control group. The ARE activity was positively correlated with HDL-C and negatively correlated with LDL-C and MDA levels in SLE patients. Whereas, in SLE patients with high BP, ARE activity was only found to be negatively correlated with MDA concentration. These data suggest that PON-55 M/M genotype is a risk factor for SLE. The carriers of this allele have high levels of MDA, neopterin and LDL-C, thus, they are more likely to develop hypertension.

Abstract
BACKGROUND Paraoxonase 1 (PON1) is a serum high-density lipoprotein-bound enzyme with antioxidant function. It hydrolyses lipid peroxides, protecting low-density lipoproteins from oxidative modifications. Patients with psoriasis are at greater risk of oxidative stress, which is associated with abnormal plasma lipid metabolism. OBJECTIVES In this study, association of the PON1 55 M allele with serum arylesterase (ARE) activity, malondialdehyde (MDA), lipid profiles and psoriasis was investigated. METHODS The present case-control study consisted of 100 patients with psoriasis with and without cardiovascular diseases (mean age 35·3 years) and 100 sex- and age-matched unrelated healthy controls (mean age 35·7 years) from the population of western Iran. The PON1 55 Met>Leu polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism. Serum ARE activity, MDA, and lipid and apolipoprotein levels were determined spectrophotometrically, by high-performance liquid chromatography and by enzyme assay, respectively. RESULTS The presence of the PON1 55 M allele was found to be associated with psoriasis (odds ratio = 1·96, P = 0·017). The patients with psoriasis with the PON1 M (M/L + M/M) allele had higher MDA levels (4·12 ± 0·88 vs. 2·24 ± 0·55 μmol L(-1) , P < 0·001), apolipoprotein B (APOB)/APOA1 ratio (0·91 ± 0·66 vs. 0·66 ± 0·35, P = 0·004), APOB (111 ± 38·7 vs. 88·3 ± 22·5 mg mL(-1) , P = 0·001) and lipoprotein(a) [LP(a)] (21·9 ± 18·4 vs. 15·8 ± 16·6 mg mL(-1) , P = 0·034), but lower ARE activity (39·6 ± 11 vs. 45·9 ± 11·8 U mL(-1) , P = 0·031) than the control subjects. ARE activity showed a significant positive correlation with APOA1 and a negative correlation with MDA concentration in patients with psoriasis. CONCLUSIONS The PON1 55 M allele is a risk factor for psoriasis. Carriers of this allele have high levels of MDA, APOB and LP(a), a high APOB/APOA1 ratio and low ARE activity. These results indicate that oxidative stress, impairment of the antioxidant system and abnormal lipid metabolism may play a role in the pathogenesis and progression of psoriasis and its related complications. These data suggest that patients with psoriasis are more susceptible to vascular diseases.

Abstract
INTRODUCTION Despite continued improvements in diagnosis, surgical techniques, and chemotherapy, breast cancer patients are still overcome by cancer metastasis. Tumor cell proliferation, invasion and metastasis are mediated, at least in part, through degradation of basement membrane by neutral matrix metalloproteinases (MMP) produced by tumor and stromal cells. Evidence suggests that MMP-9 plays a significant role in breast tumor cell invasion and metastasis. DNAzymes or catalytic oligonucleotides are new classes of gene targeting molecules that bind and cleave a specific mRNA, resulting in decreased protein expression. METHODS The application of anti-MMP-9 DNAzyme (AM9D) for the treatment of primary and metastatic breast cancer was evaluated in vitro and in vivo using MDA-MB-231 cells and the MMTV-PyMT transgenic breast cancer mouse model. Spontaneously developed mammary tumors in MMTV-PyMT transgenic mice were treated intratumorally with naked AM9D, once a week for 4 weeks. The stability of DNAzyme was determined in vitro and in vivo using fluorescently labeled DNAzyme. RESULTS AM9D specifically inhibited expression of MMP-9 in MDA-MB-231 cells resulting in reduced invasive property of these cells by 43%. Weekly intratumoral treatment of spontaneously developed mammary tumors in MMTV-PyMT transgenic mice was sufficient to significantly reduce the rate of tumor growth and final tumor load in a dose dependent and statistically significant manner (P < 0.05). This decrease in tumor growth was correlated with decreased MMP-9 protein production within the treated tumor tissues. Tumors treated with AM9D were also less vascularized and contained more apoptotic cells compared to control and untreated tumors. CONCLUSIONS These results show that targeting and down regulation of MMP-9 by AM9D could prove useful as a therapy against breast carcinoma tumor growth and invasion.

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
We have previously shown that angiotensin-converting enzyme (ACE) gene D allele is an independent risk factor for early onset coronary artery disease (CAD). Little is known about the concomitant presence of the ACE gene D allele and paraoxonase (PON1) codon 192 arginine (Arg) on the severity of CAD. Regarding the high rate of CAD among Iranians the aim of present study was to examine the hypothesis of synergistic effects between ACE-D and PON1-Arg alleles on predisposition and the severity of CAD in our population. The PON1 192 and ACE insertion/deletion (I/D) genotypes were detected by PCR-RFLP and PCR, respectively in 414 individuals undergoing their first coronary angiography. Patients were placed into one of two groups: CAD and control without CAD or diabetes. We mentioned the synergistic effects of both genes and not ACE gene alone is a risk factor for CAD. We found that PON1 Arg 192 and ACE D allele act synergistically to increase the risk of CAD (OR 1.3, P = 0.044). Our results showed a significant correlation between the possession of both PON1 192 Arg and the ACE D allele and the extent of CAD in CAD patients and CAD subjects without diabetes, represented by the increased frequency of three-vessel disease with OR 2.7, P = 0.046; χ(2) = 4, P = 0.046 and OR 2.4, P = 0.051; χ(2) = 3.8, P = 0.051, respectively. We found that PON1 Arg 192 and ACE D alleles act synergistically to increase the risk of CAD in CAD patients and CAD subjects without diabetes from west of Iran, who have high frequency of three-vessel disease. Our data suggest that PON1 192 Arg and the ACE D allele in combination with each other can be important independent risk factor for severity of CAD in patients carrying both PON1 192 Arg and the ACE D allele in a west population of Iran.

Abstract
The role of the paraoxonase (PON1) codon 192 polymorphism [glutamine (Q)/arginine (R)] in coronary artery disease (CAD) is controversial. The aim of the present study was to evaluate whether the PON1 gene polymorphism is an independent risk factor for severity of coronary artery disease in patients from west of Iran. The PON1-Arg-192 genotypes were detected by PCR-RFLP in 414 individuals undergoing their first coronary angiography. Patients were placed into one of two groups: CAD and control without CAD or diabetes. The frequency of PON1-Arg-192 allele was significantly higher in the CAD (23.4 vs. 16%, P = 0.032) than in the control group and there was a higher risk of developing CAD (OR = 1.6, P = 0.02). In addition, this difference remained significant after adjustment for without history of diabetes (OR = 1.47, P = 0.048), presence of normolipidemia and absence of history of blood pressure (OR = 1.4, P = 0.05). This result indicated PON1-Arg-192 allele is a risk factor of CAD also when correcting for conventional risk factors. We found a significant association between the PON1-Arg-192 genotype (QR + RR) and the extent of CAD in CAD patients and CAD subjects without diabetes, represented by the increased frequency of three-vessel disease with OR = 1.49, P = 0.046; χ2 = 3.82, P = 0.048 and OR = 1.46, P = 0.05; χ2 = 3.48, P = 0.051, respectively. The CAD patients carrying PON1-Arg-192 genotype (QR + RR) had lower plasma HDL-C level (P = 0.019) and higher plasma LDL-C(P = 0.01) and TG(P = 0.05). Our results indicated that PON1-Arg-192 allele can be important independent risk factor of CAD in a west population of Iran, with carriers of PON1-Arg-192 having an increased frequency of three-vessel disease and also having a distinct plasma lipids profile. Larger collaborative studies are needed to confirm these results.

Abstract
OBJECTIVE The role of angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in early onset coronary artery disease age < 55years (ECAD) is controversial. The aim of this study was to further evaluate the role of this ACE(I/D) gene polymorphism on the risk of premature CAD in patients from western Iran. METHODS The ACE(I/D) genotypes were detected by PCR-RFLP in 323 individuals undergoing their first coronary angiography. Patients were placed into two groups: ECAD and late onset CAD age ≥ 55years (LCAD). RESULTS We found a statistically significant association of the ACE D allele, as homozygous or ACE ID plus DD genotypes (ID+DD), only in the ECAD subjects OR=1.35, p=0.015, OR=3.27, p=0.014, and OR=2.8, p=0.013, respectively. In addition, there was a significant association after adjustment for the absence of history of diabetes, presence of normolipidemia and absence of history of blood pressure [OR 1.38, p=0.017 and 2.35, p=0.02]. Our results indicated that the ACE D allele is a risk factor for early onset of CAD even after correcting for conventional risk factors. The incidence of triple vessel disease was significantly higher in individuals carrying ACE(D/D) genotype in ECAD patients compared to those who carried ACE(I/I) genotype (OR 3.38; p=0.019; 57.5% vs. 42.5%; p=0.013). CONCLUSION The presence of D allele of ACE can be important independent risk factor in the onset of CAD patients less than 55 years old in a west population of Iran. Larger collaborative studies are needed to confirm these results.

Abstract
We have previously shown that butyrylcholinesterase-K (BCHE-K, G1615A/Ala539Thr) variant increases the risk of coronary artery disease (CAD). In addition, we have found that the presence of APOE-epsilon 4 allele augments the risk of CAD in patients with type II diabetes mellitus (T2DM/CAD). Here we explored the concomitant presences of two alleles of the BCHE-K and APOE-epsilon 4 in increasing the risk of CAD or diabetes in T2DM patients with or without CAD and CAD patients without T2DM. This case-control study comprised 631 subjects undergoing their first coronary angiography. They were matched and randomly assigned into four groups: type II diabetic patients with no sign of CAD (T2DM), type II diabetic patients with CAD/ND (T2DM/CAD), CAD patients with no sign of diabetes (CAD/ND), and healthy individuals (NCAD/ND). BCHE-K variant and APOE genotypes were detected by PCR-RFLP and serum lipid level was measured enzymatically. We found that BCHE-K and APOE-epsilon 4 allele act synergistically to increase the risk of CAD in both T2DM, non-diabetic and total CAD (TCAD = T2DM/CAD + CAD/ND) individuals. The level of synergy 1.5 and 1.2 fold are higher in CAD patients (OR = 4.5; P = 0.011) with T2DM than the non-diabetic CAD patients (OR = 3.07; P = 0.024) and TCAD patients (OR = 3.74; P = 0.018), respectively. The CAD subjects with and without T2DM and TCAD patients carrying both APOE-epsilon 4 allele and BCHE-K had significantly lower plasma HDL-C (P values = 0.008, 0.047, and 0.036, respectively) and higher plasma LDL-C (P values = 0.025, 0.048, and 0.04, respectively), than that of the control carriers both APOE-epsilon 4 and BCHE-K. We have found that BCHE-K and APOE-epsilon 4 allele not only act synergistically to increase the risk of CAD, particularly in T2DM subjects in population from western Iran, who have high levels of LDL-C and low levels of HDL-C, suggesting that a specific therapeutic intervention should be considered for these particular groups of patients.

Abstract
BACKGROUND Butyrylcholinesterase (BuChE) catalyzes the hydrolysis of acetylcholine and other choline esters and is also involved in lipid metabolism. The purpose of this study was to investigate any association between BuChE serum phenotype and activity and lipid profile of ischemic stroke patients. METHODS We determined serum BuChE activities and phenotypes, and levels of total cholesterol (TC), LDL-C, HDL-C and triacylglyerol (TG) in 33 patients with acute ischemic stroke within 12 h of the onset of the attack and 29 controls. RESULTS The mean (+/-SD) serum BuChE activity and the BuChE of U/A phenotype in the stroke individuals were significantly lower and higher than that of the control (315 (+/-124) IU/L. vs. 384 (+/-99) IU/L, p=0.02, t=-2.4 and 21.2% vs.3.4%, p=0.026 respectively). CONCLUSIONS Our results showed that a negative correlation between BuChE activity with TC level, in addition the frequency of BuChE phenotypes with low activity is high in stroke patients, who have high levels of cholesterol, may have increased susceptibility to stroke.

Abstract
The molecular polymorphism displayed by apolipoprotein E (APOE) has been listed as a risk factor for susceptibility to various disorders, such as those associated with lipid metabolism, arteriosclerosis, coronary artery disease (CAD), and Alzheimer disease. To evaluate the role of APOE genotypes as risk factors for Alzheimer disease, CAD, and atherosclerosis in the Kurdish population of Kermanshah, Iran, we studied the frequencies of APOE alleles *2, *3, and *4 and genotypes in 914 healthy Kurdish subjects (514 men and 400 women). The highest frequency of APOE in the Kurdish population was found for APOE*3 (87.87%). The APOE*2 and APOE*4 allele frequencies were 6.66% and 5.45%, respectively. Distribution of APOE genotypes and alleles was not significantly different between male and female subjects (p > 0.05). Interestingly, the order of the frequency of APOE alleles (*3-->*2-->*4) in the Kurdish population was quite different from that reported for most populations in the world (*3-->*4-->*2). The findings of the present study can be used to identify individuals with high risk of CAD and atherosclerosis and suggest a preventive measure to reduce their susceptibility.

Abstract
OBJECTIVE There are evidence suggesting that APOE-varepsilon4 allele play an important role in the pathogenesis of Alzheimer's disease (AD) by reducing peripheral levels and activities of a broad spectrum of nonenzymatic and enzymatic antioxidants systems. However, the link between APOE genotype, oxidative stress, and AD has yet to be established. In this study we examined whether antioxidant defense mechanism exacerbates the risk of AD in individual carrying APOE-varepsilon4 allele in a population from Tehran, Iran. METHOD We determined the enzymatic activities of the erythrocyte Cu-Zn superoxide dismutase (Cu-Zn SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and serum level of total antioxidant status(TAS) in various APOE genotypes in 91 patients with AD and 91 healthy subjects as control group (age and sex-matched). RESULT The results showed that the TAS level and the activities of enzymatic antioxidants CAT and GSH-Px were significantly lower and the SOD activity was significantly higher in AD patients compared to controls. The AD patients with APOE-varepsilon4 allele genotype had significantly lower serum TAS concentration and lower erythrocytes GSH-Px and CAT activities (p=0.001) but significantly higher erythrocytes Cu-Zn SOD activity (p=0.001) than the non-APOE-varepsilon4 carrier AD and the control group. In addition, the association observed between the factors involved in an antioxidant defense mechanism and APOE-varepsilon4 allele in AD increased with age of the subjects. CONCLUSION These data indicate that the reduced serum level of TAS and activity of CAT, GSH-Px and increased SOD exacerbate the risk of AD in individuals carrying APOE-varepsilon4 allele. The reduced antioxidants defense in APOE-varepsilon4 allele carrier may contribute to beta-amyloidosis. This effect, however, is more pronounced in the AD patients older than 75 years of age. This suggests that a therapeutic modality should be considered for these subjects.

Abstract
The collagenases are members of the matrix metalloproteinase family (MMP) that degrade native triple-helical type I collagen. To understand the mechanism by which these enzymes recognize and cleave this substrate, we studied the substrate specificity of a modified form of MMP-1 (FC) in which its active site region (amino acids 212-254) had been replaced with that of MMP-9 (amino acids 395-437). Although this substitution increased the activity of the enzyme toward gelatin and the peptide substrate Mca-PLGL(Dpa)AR-NH2 by approximately 3- and approximately 11-fold, respectively, it decreased the type I collagenolytic activity of the enzyme to 0.13%. The replacement of Gly233, the only amino acid in this region of FC that is conserved in all collagenase family members, with the corresponding Glu residue in MMP-9 resulted in a substantial decrease in the type I collagenolytic activity of the enzyme without affecting its general proteolytic activities. The kinetic parameters of the FC/G233E mutant for the collagen substrate were similar to those of the chimeric enzyme. In addition, substituting Gly233 for Glu in the chimera increased the collagenolytic activity of the enzyme by 12-fold. Interestingly, replacing Glu415 in MMP-9 with Gly, its corresponding residue in FC, endowed the enzyme with type I collagenolytic activity. The catalytic activity of the MMP-9 mutant toward triple-helical type I collagen was 2-fold higher than that of the collagenase chimera. These data in conjunction with the X-ray crystal structure of FC indicate that Gly233 provides the flexibility necessary for the enzyme active site to change conformation upon substrate binding. The flexibility provided by the Gly residue is essential for type I collagenolytic activity.

Abstract
The conflicting results of several studies suggest that there is an association between the butyrylcholinesterase-K variant (BCHE-K, G1615A/Ala539Thr) and the risk of developing coronary artery disease (CAD) in diabetes and non-diabetic subjects. The objective of this study was to determine whether the presence of the BCHE-K variant exacerbates the risk of CAD in patients from western Iran with and without type 2 diabetes mellitus (T2DM). This case-control study comprised 464 subjects undergoing their first coronary angiography. They were matched and randomly assigned into four groups: CAD+T2DM+ (CAD/T2DM), CAD+DM(-) (CAD/ND), CAD(-)DM+ (T2DM/NCAD) and CAD(-)DM(-)(control). The BCHE-K variant was detected by PCR-RFLP. The BCHE-K allele frequency in CAD patients with and without T2DM [total CAD (TCAD)] and separately for each group (CAD/T2DM and CAD/ND) was significantly higher than in the control group (21.1 % versus 13.3 % (p = 0.001), 22.4 % versus 13.3 % (p = 0.001) and 19.7 % versus 13.3 % (p = 0.015), respectively). The odds ratios (ORs) for the BCHE-K heterozygous and homozygous variants in TCAD subjects were 1.65 (95 % CI 1.17-2.3; p = 0.004) and 4.3 (1.05-19.4; p = 0.048); for CAD/T2DM individuals 1.76 (1.2-2.6; p = 0.004) and 4.73 (0.96-23.3; p = 0.052); and for CAD/ND patients 1.53 (1.05-2.3; p = 0.029) and 3.88 (0.8-19.7; p = 0.7), respectively. The OR of the BCHE-K allele was found to be 1.74 (1.1-2.4; p = 0.001) in TCAD subjects, 1.87 (1.12-1.48; p = 0.001) in the CAD/T2DM group and 1.59 (1.04-1.4; p = 0.016) in CAD/ND subjects. These data suggest that the BCHE-K allele increases the risk of CAD in the population (with and without DM) in western parts of Iran, and its presence intensifies the risk of CAD in T2DM. The fact that the BCHE-K allele, even in the heterozygous form, exacerbates the risk of CAD in this population, suggests that a specific therapeutic intervention should be considered for this particular group of patients.

Abstract
Human matrix metalloproteinase 9 (MMP-9), also called gelatinase B, is particularly involved in inflammatory processes, bone remodelling and wound healing, but is also implicated in pathological processes such as rheumatoid arthritis, atherosclerosis, tumour growth, and metastasis. We have prepared the inactive E402Q mutant of the truncated catalytic domain of human MMP-9 and co-crystallized it with active site-directed synthetic inhibitors of different binding types. Here, we present the X-ray structures of five MMP-9 complexes with gelatinase-specific, tight binding inhibitors: a phosphinic acid (AM-409), a pyrimidine-2,4,6-trione (RO-206-0222), two carboxylate (An-1 and MJ-24), and a trifluoromethyl hydroxamic acid inhibitor (MS-560). These compounds bind by making a compromise between optimal coordination of the catalytic zinc, favourable hydrogen bond formation in the active-site cleft, and accommodation of their large hydrophobic P1' groups in the slightly flexible S1' cavity, which exhibits distinct rotational conformations of the Pro421 carbonyl group in each complex. In all these structures, the side-chain of Arg424 located at the bottom of the S1' cavity is not defined in the electron density beyond C(gamma), indicating its mobility. However, we suggest that the mobile Arg424 side-chain partially blocks the S1' cavity, which might explain the weaker binding of most inhibitors with a long P1' side-chain for MMP-9 compared with the closely related MMP-2 (gelatinase A), which exhibits a short threonine side-chain at the equivalent position. These novel structural details should facilitate the design of more selective MMP-9 inhibitors.

Abstract
OBJECTIVE It has been suggested that there is a relationship between apolipoprotein E polymorphism and the severity of coronary artery disease in type II diabetes mellitus (T2DM). The current study specifically aimed to examine whether APOE polymorphism in association with serum lipids-lipoproteins level is a risk factor for developing coronary artery disease (CAD) in diabetic patients living in western of Iran. METHODS The APOE genotypes were detected by PCR-RFLP in 152 angiographically documented diabetic CAD patients, 262 non-diabetic (ND) individuals with CAD and 300 unrelated controls (normal coronary artery cases without diabetes) and serum lipid level was measured enzymatically. RESULTS The APOE-epsilon4 and epsilon2 allele frequencies were significantly higher in the CAD/T2DM and CAD/ND patients than in the control group (p<0.001). Our study demonstrated a significant association between APOE polymorphism and the level of plasma lipids with CAD/T2DM (p=0.001) and CAD/ND (p=0.026) patients. The CAD subjects with T2DM and ND patients carrying APOE-epsilon4 allele had lower plasma HDL-C level (p<0.001), (p=0.008) but had higher plasma LDL-C (p=0.01), total cholesterol (p=0.002), (p=0.03) and TG (p<0.001), (p=0.042) than that of the APOE-epsilon3 carriers, respectively. However, carriers of APOE-epsilon2 had significantly higher levels of plasma TG only. OR of APOE-epsilon4 and epsilon2 alleles in CAD/T2DM and CAD/ND patients were found to be 2.98 (p=0.001),1.86 (p=0.001), 2 (p=0.001), and 1.65 (p=0.001), respectively. CONCLUSIONS The major finding of the present case-control study is that T2DM patients carrying APOE-epsilon2 and epsilon4 alleles have a higher risk of developing CAD than ND patients in the western population of Iran, with APOE-epsilon4 being more closely associated with CAD than the APOE-epsilon2 allele. These results indicated that carriers of APOE-epsilon4 allele have a distinct plasma lipids profile and carrier of this allele with low levels of HDL-C and with high levels of LDL-C may be susceptible to CAD and myocardial infarction specially in diabetic patients. This suggests that a therapeutic modality should be considered for these patients.

Abstract
OBJECTIVE The best known clinical application of serum BChE assay is to predict abnormally prolonged apnea following the application of the muscle relaxant succinylcholine. The aim of the present study was to assess the frequency of BChE phenotypes and to predict the risk of apnea for those receiving succinylcholine among the residents in western Iran. METHODS We examined the frequency of nine BChE phenotypes in 1548 volunteers including 816 males and 732 females with the mean age of 35+/-15 years from an apparently healthy group living in western Iran. The frequencies of BChE phenotypes were determined using BChE activity measurements and by inhibition with dibucaine, fluoride, and the compound Ro2-0683 (Hoffman-La-Roche). RESULTS The reference range for serum total BChE activity was 4600-14000 U/L (using butyrylthiocholine iodide as substrate). The mean value obtained for men (9030 U/L) was significantly (p<0.05) higher than that for women (8550 U/L). The frequencies of four alleles U, A, F, S were calculated to be 0.9826, 0.0165, 0.008 and 0.001, respectively. The frequency of phenotypes of BChE was as follows: normal phenotype (UU) 95.5%, moderate sensitive to succinylcholine including UA,US,UF phenotypes was 3.9% and hypersensitive to succinylcholine (AA, AF, AS, FF, SS) was 0.58%. CONCLUSION This study indicates that the population of western Iran has a medium frequency of succinylcholine-sensitive individuals compared to other populations. We suggest that determination of BChE activity and phenotype by the micro automated method is well suited to pre-operative screening and detection of at-risk of prolonged apnea in persons receiving succinylcholine in the healthy population of western Iran.

Abstract
We have recently demonstrated that apolipoprotein E (APOE)-varepsilon4 allele is a risk factor for Alzheimer disease (AD) in Tehran, Iran. The current study specifically aimed to examine whether APOE polymorphism in association with serum lipids-apolipoprotein level is a risk factor for AD in a population from Tehran, Iran. APOE polymorphism and plasma lipids, apoA1, apoB and lipoprotein (a) (Lp(a)) levels were determined in 94 AD patients and 111matched controls. Our study demonstrated a significant association between APOE polymorphism and the level of plasma lipids and apolipoprotein with AD in this population. The AD subjects had significantly lower apoA1 (p<0.001) and HDL-C (p<0.01) and higher apoB (p=0.01) and LDL-C (p=0.02) levels than that of the control group. The AD subjects carrying APOE-varepsilon4 allele had lower plasma apoA1 (t=5.2, p<0.002) and HDL-C level (t=2.7, p=0.01) but had higher plasma apoB (t=-5.4, p<0.002), LDL-C (t=-4.6, p=0.005) and total cholesterol (TC) (t=-2.7, p=0.01) than that of the non APOE-varepsilon4 carriers. These results indicated that AD patients with APOE-varepsilon4 allele has a distinct plasma lipid profile and carrier of this allele with low levels of apoA1 and HDL-C may be more susceptible to AD.

Abstract
OBJECTIVE Coronary artery disease (CAD) is the major cause of death in developing countries, such as Iran. The apolipoprotein E gene (APOE) is considered an important genetic determinant of CAD. In this study, the relationship between APOE polymorphism with lipid variation in CAD patients in Kermanshah, Iran was investigated. METHODS This case-control study consisted of 115 CAD patients who angiographically had at least 30% stenosis and 135 unrelated controls. APOE polymorphism was detected by PCR-RFLP and serum lipid level was measured enzymatically. RESULTS The APOE-epsilon4 and -epsilon2 allele frequencies were significantly higher in the CAD patients than in the control group (P < 0.001). The CAD patients with epsilon3/epsilon4 genotype had also higher TC (P < 0.001) and LDL-C (P < 0.01) and lower HDL-C (P < 0.03) levels than that of the control group. CONCLUSIONS APOE-epsilon4 allele is a risk factor for CAD, so that carriers of this allele with high levels of LDL-C may be susceptible to CAD and myocardial infarction.

Abstract
To investigate adult neural stem cell (NSC) biology in relation to glioma, the C6 glioma cell line was tagged with green fluorescent protein (GFP) and inoculated into the brain of adult rats. The in vivo biological response of the brain to glioma was studied using immunohistochemical analysis of the subventricular zone (SVZ), peritumoral areas, and glioma. Nestin immunoreactive cells were found infiltrating glioma, but the distribution of abnormal immunoreactivity was restricted to the dorsal and medial border of the tumor relative to the ipsilateral ventricle. The SVZ was found to be hypertrophic, hypercellular, and up-regulated nestin expression. Furthermore, a dense contiguous population of nestin immunoreactive cells could be found streaming from ipsilateral dorsal tip of the SVZ, tracking along the ventral margin of the corpus callosum, and fanning out to encompass and infiltrate the proximal tumor border. Although most cells were either nestin or glial fibrillary acidic protein (GFAP) immunoreactive in the SVZ and along the ventral margin of the corpus callosum, the number of cells co-expressing both markers increased proportionally as the tumor was approached so that the predominant cell population along the proximal tumor border was GFAP immunoreactive. Finally, we demonstrated that a significant proportion of cells found in areas of abnormal immunoreactivity were proliferating, especially in peritumoral areas. In summary, there is an induction of neuropoietic activity in a rat intracranial glioma model that results in an infiltration and accumulation of abnormal nestin and GFAP expressing cells with proliferative potential along the dorsal and medial border of intracranial C6 glioma.
