  • The human paraoxonases (PON) are a group of anti-oxidative enzymes that catalyze important reactions in body. Some polymorphic variations within the PON genes have been reported to relate with several... diseases. In this article, the polymorphisms of the PON upstream regions were evaluated to predict their positions within elements of transcription factors by similarity tools. However, taxonomy studies suggested the PON2 duplication on the chromosome 7 but pairwise alignments did not show vast similarity among the fragments of PON promoters. Multiple sequence alignment (MSA) tool showed the PON1 T-107C and PON3 C-31T positions are conserved within several transcription elements. Based on these tools, the review assumes that the PON upstream regions have no similarity and only two polymorphisms are considered to interact with several transcription factors.Show more

  • HDL-associated paraoxonase1 (PON1) is believed to be an important anti-oxidative enzyme in the retardation of atherosclerosis. In this study, we determined haplotypes of three SNPs within the PON1 gen...e promoter to elucidate association of functional sites with coronary artery disease (CAD). We applied a direct haplotyping procedure through ARMS (Amplification Refractory Mutation System) and RFLP (Restriction Fragment Length Polymorphism) analysis techniques. The haplotypes of the G(-907)C, A(-162)G and C(-107)T polymorphisms within the 5 region of the PON1 gene were determined in 99 patients and 66 controls who were evaluated angiographically for the presence and extent of stenosis in coronary arteries. The genotype and haplotype distributions had significant differences between patient subgroups (One-, Two- and Three-vessel disease) but not between the patient and control groups. Multivariate analyses suggested decreased arylesterase activity is the most important independent factor in the CAD severity. The increase of high activity variants [G(-907) and C(-107)] within the two-allelic haplotypes was reversely associated with the extent of stenosis in coronary arteries. However, we could not determine the independent involvement each of the C(-107)T and G(-907)C polymorphisms on the extent of stenosis. We found no significant association between the A(-162)G polymorphism and the extent of stenosis in vessels. The study indicated the association of polymorphic variations within the PON1 gene promoter haplotypes with the serum arlyesterase activity. The arlyesterase activity was also associated with the extent of stenosis in coronary arteries but not with primary development of atherosclerosis.Show more

  • The neutrophil myeloperoxidase (MPO) promotes the oxidative stress by the production of active chlorinated molecules. The aim of this study was to investigate the association between MPO promoter poly...morphic variants (rs2243827 and rs2333227) and, its serum level in patients with the stenosis of coronary arteries. Furthermore, a system approach was applied to create the MPO transcription factor network. A total of one hundred fifty six subjects (controls, stenosis<5%, n=71 and patients, stenosis>70%, n=85) undergoing coronary angiography were recruited. The polymorphic haplotypes and serum MPO level were identified using ARMS-PCR and ELISA techniques, respectively. The MPO transcription factor network was primarily created with PSICQUIC and ChIP data and, was improved with the predicted transcription factors. The regression analyses did not show an association between the serum MPO level and the extent of stenosis in coronary arteries. The network showed that the predicted transcription factors at the flanking regions of polymorphic variants are not directly interacted to MPO. In conclusion, the population and prediction studies showed no association between the serum MPO level, the promoter high-frequency polymorphic frequencies and the extent of stenosis in coronary arteries. A gene sub-cluster with MYB as central node was suggested to be involved with MPO on the transcription factor network.Show more

  • The macrophage polarization is proposed to be involved in initial events and remodeling of atherosclerosis plaques. Mannose receptor, C type 1 (MRC1) is a trans-membrane glycoprotein participating in ...phagocytosis and, is highly expressed in the M2 macrophages. The aim of this study was to investigate the effects of sdLDL (small dense LDL) on the MRC1 gene expression level and secretion of histamine in the differentiated M2 macrophages from monocytes of patients with coronary artery stenosis and healthy subjects. The monocytes were isolated from healthy subjects (< 5% stenosis) and patients (>70% stenosis, SVD (Single Vessel Disease), 2VD (Two-Vessel Disease) and 3VD (Three-Vessel Disease)) by RosetteSep kit and, were differentiated into M2 macrophages by macrophage colony-stimulating factor (M-CSF). The sdLDL particles were obtained by PEG-combined precipitation method. The MRC1 gene expression and histamine levels were measured by RT-qPCR and ELISA techniques, respectively. The MRC1 gene expression level was significantly increased in M2 macrophages of healthy subjects (P=0.05) while it reduced in SVD (P=0.05), 2VD (P=0.01) and 3VD (P=0.9) patients after treatment with sdLDL. The histamine value secreted from M2 macrophages (7-day) was higher (>3-fold, P=0.02) in patients as compared to healthy controls. The results showed that the sdLDL particles reduce the MRC1 gene expression levels in the differentiated M2 macrophages from patients with coronary artery disease. Furthermore, they had high inflammatory capacity for the secretion of histamine.Show more

  • Age-related hearing impairment, or presbycusis, is the most common communication disorder and neurodegenerative disease in the elderly. Its prevalence is expected to increase, due to the trend of grow...th of the elderly population. The current diagnostic test for detection of presbycusis is implemented after there has been a change in hearing sensitivity. Identification of a pre-diagnostic biomarker would raise the possibility of preserving hearing sensitivity before damage occurs. Mitochondrial dysfunction, including the production of reactive oxygen species and induction of expression of apoptotic genes, participates in the progression of presbycusis. Mitochondrial DNA sequence variation has a critical role in presbycusis. However, the nature of the relationship between mitochondrial DNA copy number, an important biomarker in many other diseases, and presbycusis is undetermined.Show more

  • Age-related hearing impairment (ARHI) is a progressive and a common sensory disorder in the elderly and will become an increasingly important clinical problem given the growing elderly population. Apo...ptosis of cochlear cells is an important factor in animal models of ARHI. As these cells cannot regenerate, their loss leads to irreversible hearing impairment. Identification of molecular mechanisms can facilitate disease prevention and effective treatment. In this study, we compared the expression of the genes BAK1 and BCL2 as two arms of the intrinsic apoptosis pathway between patients with ARHI and healthy subjects. ARHI and healthy subjects were selected after an ear nose throat examination, otoscopic investigation, and pure tone audiometry. RNA was extracted from peripheral blood samples, and relative gene expression levels were measured using quantitative real-time polymerase chain reaction. BAK1 and the BAK1/BCL2 ratio were statistically significantly upregulated in the ARHI subjects. The BAK1/BCL2 ratio was positively correlated with the results of the audiometric tests. Our results indicate that BAK-mediated apoptosis may be a core mechanism in the progression of ARHI in humans, similar to finding in animal models. Moreover, the gene expression changes in peripheral blood samples could be used as a rapid and simple biomarker for early detection of ARHI.Show more

  • Matrix Gla protein (MGP) is involved in calcium trafficking and arterial calcification. The aim of study was to investigate the role of three polymorphisms within the MGP gene promoter region on repor...ter gene (luciferase) expression level. The fragments containing rs1800799 (C/T), rs1800802 (T/C), and rs1800801 (G/A) sites were constructed and transferred into human G292 osteoblast cells using pGL3-Basic plasmid. The reporter gene expression was calculated for the high and low frequency polymorphic haplotypes (CTG and TCA, respectively). Results showed that the reporter gene expression levels are not statistically different (p > 0.3). We concluded that the investigated polymorphic sites are not able to change the gene expression pattern in human G292 osteoblast cells.Show more

  • This study aimed to assess the possible association of bacterial vaginosis (BV) and early miscarriage in 408 women undergoing intracytoplasmic sperm injection (ICSI) for reasons of male infertility. A... vaginal sample was obtained before oocyte retrieval and evaluated for BV-associated bacteria using the Nugent scoring system. The primary outcome was early miscarriage and the secondary outcomes included implantation, pregnancy, late miscarriage, preterm delivery and live birth rates. Chi-square, ANOVA, relative risk and odds ratio were used for data analysis where appropriate. The prevalence of BV was estimated as 7.3%. From 336 patients who had embryo transfer, 138 patients (41.1%) conceived. A total of 17% (n = 23) of pregnant women miscarried during the first trimester: 15 patients (15%) were normal, 4 (17.4%) were intermediate and 4 (26.7%) patients had BV (p = 0.52). The relative risk of early miscarriage in BV patients compared to the non-BV and intermediate group was 1.77 (0.68-4.64, 95% CI). Implantation, pregnancy, preterm delivery and live birth rates were comparable between groups. We conclude that BV does not appear to have an adverse impact on outcomes in women being treated with ICSI for male factor infertility and is not associated with miscarriage and preterm birth.Show more

  • This study aimed to assess the possible association between ovarian auto-antibodies and poor ovarian response to controlled ovarian hyperstimulation (COH) in patients undergoing intracytoplasmic sperm... injection (ICSI) cycles. In total, 42 poor responders and 43 male factor subjects were enrolled in the study and underwent either a standard long gonadotropin-releasing hormone (GnRH) agonist or antagonist protocol. Anti-ovarian, anti-oocyte, anti-zona pellucida (anti-ZP) and anti-gonadotropin antibodies in their sera and follicular fluid (FF) were measured by an enzyme-linked immunosorbent assay technique (ELISA). The mean follicular fluid anti-oocyte antibody [ratio of optical density (OD) sample/OD Control] was significantly higher in poor responders compared to the normal group (2.40 ± 1.55 versus 1.72 ± 0.71, p = 0.012). The linear regression analysis showed an inverse correlation between FF anti-oocyte antibody concentrations and the number of: (i) retrieved oocytes (B = -1.212, r = -0.235, p = 0.030); (ii) mature oocytes (B = -1.042, r = -0.234, p = 0.031); (iii) embryos available (B = -0.713, r = -0.228, p = 0.036); and (iv) good quality embryos (B = -0.369, r = -0.229, p = 0.035). However, there were no significant differences between two groups in terms of FF and serum anti-ovarian, anti-gonadotropins and anti-ZP antibodies. The Pearson correlation analysis on 85 infertile patients showed a positive correlation between age and the levels of FF anti-oocyte antibody (r = 0.276, p = 0.010). This study demonstrated that FF anti-oocyte antibody could be associated with poor response to COH in ICSI cycles.Show more

  • This prospective study was performed from June 2012 to June 2014 at Royan Institute to compare the predictive values of serum anti-müllerian hormone (AMH), antral follicle count (AFC) and ovarian resp...onse prediction index (ORPI) ([AFC × AMH]/age) for in vitro fertilisation/intracytoplasmic sperm injection (IVF/ICSI) cycle outcomes. Five hundred and fifty women included in the study with male factor and unexplained infertility were the first candidates for IVF/ICSI cycles. Serum AMH level was measured by a commercial ELISA kit and AFC was calculated by a transvaginal ultrasonography on day 2-3 of the menstrual cycle before starting ovarian stimulation. All women underwent IVF/ICSI cycles using a long standard protocol with gonadotropin-releasing hormone agonist. The receiver operating characteristic curves (ROC) analysis showed that both AMH and AFC were good predictors of ovarian response with an area under the curves (AUC) > 0.75; even it seems that AFC was being a better predictor. Combining these variables is necessary as ORPI will not improve the prediction value. All the variables had poor predictive ability (AUC <0.60) for clinical pregnancy and live birth rates. Logistic regression analysis showed the AMH less than 0.4 ng/ml and quality of transferred embryos were significant predictors for clinical pregnancy rate.Show more

  • Male infertility is a multifactorial disorder, which affects approximately 10% of couples at childbearing age with substantial clinical and social impact. Genetic factors are associated with the susce...ptibility to spermatogenic impairment in humans. Recently, SEPT12 is reported as a critical gene for spermatogenesis. This gene encodes a testis specific member of Septin proteins, a family of polymerizing GTP-binding proteins. SEPT12 in association with other Septins is an essential annulus component in mature sperm. So, it is hypothesized that genetic alterations of SEPT12 may be concerned in male infertility.Show more

  • Sperm motility is known as an effective parameter in male fertility, and it depends on energy consumption. Low-level laser irradiation could increase energy supply to the cell by producing adenosine t...riphosphate. The purpose of this study is to evaluate how the low-level laser irradiation affects the human sperm motility. Fresh human semen specimens of asthenospermic patients were divided into four equal portions and irradiated by 830-nm GaAlAs laser irradiation with varying doses as: 0 (control), 4, 6 and 10 J/cm(2). At the times of 0, 30, 45 and 60 min following irradiation, sperm motilities are assessed by means of computer-aided sperm analysis in all samples. Two additional tests [HOS and sperm chromatin dispersion (SCD) tests] were also performed on the control and high irradiated groups as well. Sperm motility of the control groups significantly decreased after 30, 45 and 60 min of irradiation, while those of irradiated groups remained constant or slightly increased by passing of time. Significant increases have been observed in doses of 4 and 6 J/cm(2) at the times of 60 and 45 min, respectively. SCD test also revealed a non-significant difference. Our results showed that irradiating human sperms with low-level 830-nm diode laser can improve their progressive motility depending on both laser density and post-exposure time.Show more

  • Bombay phenotype is one of the rare phenotypes in the ABO blood group system that fails to express ABH antigens on red blood cells. Nonsense or missense mutations in fucosyltransfrase1 (FUT1) and fuco...syltransfrase2 (FUT2) genes are known to create this phenotype. This blood group is compatible with all other blood groups as a donor, as it does not express the H antigen on the red blood cells. In this study, we describe the establishment of human induced pluripotent stem cells (iPSCs) from the dermal fibroblasts of a Bombay blood-type individual by the ectopic expression of established transcription factors Klf4, Oct4, Sox2, and c-Myc. Sequence analyses of fibroblasts and iPSCs revealed a nonsense mutation 826C to T (276 Gln to Ter) in the FUT1 gene and a missense mutation 739G to A (247 Gly to Ser) in the FUT2 gene in the Bombay phenotype under study. The established iPSCs resemble human embryonic stem cells in morphology, passaging, surface and pluripotency markers, normal karyotype, gene expression, DNA methylation of critical pluripotency genes, and in-vitro differentiation. The directed differentiation of the iPSCs into hematopoietic lineage cells displayed increased expression of the hematopoietic lineage markers such as CD34, CD133, RUNX1, KDR, alpha-globulin, and gamma-globulin. Such specific stem cells provide an unprecedented opportunity to produce a universal blood group donor, in-vitro, thus enabling cellular replacement therapies, once the safety issue is resolved.Show more

  • Macrophage migration inhibitory factor (MIF) is an important pro-inflammatory cytokine expressed at sites of inflammation. We have assessed this factor (MIF) in urinary tract infections with the aim o...f determining a non-invasive and sensitive method to differentiate upper and lower renal involvement. Thirty-three pediatric patients with urinary track infection (25 with acute pyelonephritis, eight with acute cystitis) and 40 healthy subjects were recruited for this prospective case-control study. Pyelonephritis was differentiated from cystitis by dimercaptosuccinic acid (DMSA) scan. Urinary MIF concentration was determined using an enzyme-linked immunosorbent assay method. The urine MIF/creatinine (Cr) ratio was significantly higher in pyelonephritis patients than in those with acute cystitis and the control group (P < 0.001). The optimal cut-point of 4.90 pg/micromol Cr for the urine MIF/Cr ratio has the potential to be a biomarker for distinguishing patients with acute pyelonephritis from those with acute cystitis. Determination of the urinary MIF was also useful in selecting the patients at risk of permanent renal damage. Of those patients with pyelonephritis, based on the DMSA scan at the time of infection, scarring on follow-up DMSA scan 9-12 months later occurred in patients with the highest urinary MIF/Cr ratios. We conclude that the urine MIF/Cr ratio is a sensitive test for differentiating acute pyelonephritis from acute cystitis and also for detecting children with acute pyelonephritis who are at a higher risk for permanent renal scars in the future.Show more

  • Ureaplasma urealyticum is a causative agent of non-gonococcal urethritis and is implicated in the pathogenesis of prostatitis, epididymitis and infertility. The organism is more common in partners of ...infertile than fertile marriages. U. urealyticum infections not only jeopardize fertility but also pose a risk for infertility treatment and resulting pregnancies. The aim of this study was to determine the prevalence of U. urealyticum and Ureaplasma parvum in semen of infertile and healthy men by polymerase chain reaction (PCR). Semen samples were obtained from infertile patients and healthy controls and were subjected to the routine andrological analysis and PCR. DNA was extracted by the Cadieux method, and analysed by PCR protocol with specific primers for urease and multiple-banded antigen genes. Ureaplasmas were detected significantly by PCR in 12 of 100 (12%) semen specimens from infertile patients and in three of 100 (3%) healthy men. The volume of semen fluid, concentration of sperm cells, and sperm cell with normal morphology were significantly decreased in infertile men. In the group of infertile patients with PCR positive for Ureaplasmas, the volume, count and morphology of semen samples were lower than in the infertile patients with PCR-negative results. U. urealyticum species in semen of infertile men was found to be high (9%) than in healthy controls (1%). Detection rate for U. parvum was 3% in the infertile group and 2% in healthy men. The results indicate that U. urealyticum species is more common in specimens of infertile men. The percentage of normal sperm cells, the volume of semen and the percentage of sperm cells with motility in the PCR positive for U. urealyticum species group were lower than in the PCR positive for U. parvum group.Show more
