AbstractBackground/Aim: Increased levels of matrix metalloproteinase-8 (MMP-8) have been associated with risk of developing chronic periapical lesion (CPL). Gene polymorphisms are contributing factors in the pathogenesis of the inflammation. The aim of this study was to analyze polymorphism in the gene MMP-8 and its association and influence on clinical manifestation of CPL.Methods: A total of 240 unrelated Macedonian subjects were included in the present study. Polymorphism -799 C/T in the gene MMP-8 detected with restriction enzyme BgIII was studied in 120 patients with CPL and 120 controls without any signs of chronic or acute inflammatory process in the jaw. The amplification of the region of selected gene was made with polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP).Results: Our results showed that there were differences in the allele and genotype frequencies of the MMP8 -799 C/T polymorphisms between patients with CPL and controls (p < 0.05). Also this study suggests that MMP-8 polymorphism -799 C/T was a risk for expression of CPL (OR=8.27<3.44<OR<20.26).Conclusion: The detection of this genetic polymorphism is relevant for obtaining providential treatment of patients who are at high risk of chronic periapical inflammation.

This study's objective was to determine the distribution of allele frequencies of CYP2C9 and CYP2C19 gene polymorphisms among the Papuan population, known as the second-largest ethnic group in Indonesia. According to recent research, there is a decrease in CYP2C9 and CYP2C19 produced by humans globally, including in Indonesia. These gene polymorphisms aid in the transmission of various endogenous and exogenous drugs in the human body. Material and Methods: A sum of 99 subjects, comprising 73 male and 26 female subjects aged 20-30 years, were used for this research. PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis using AvaII, NsiI, and SfaNI enzymes tested for the genotypes CYP2C9 and CYP2C19 administered. The distribution of genotypes was calculated in the population (P<0.05) using the Hardy-Weinberg equilibrium. The Faculty of Medicine Gadjah Mada University's Medical and Health Research Ethics Committee (MHREC) accepted this research with written consent. The results revealed that in Papua subjects, CYP2C9*2 (rs1799853) and CYP2C19*17 (rs12248560) alleles were absent while in 17 percent of the population CYP2C9*3 (rs1057910) allele frequency was. In conclusion, CYP2C9*3 has the highest polymorphism rate in Indonesia, with the absence of CYP2C9*2 and CYP2C19*17. Therefore, genetic drift can occur within this ethnic group.

The aim of this study was to identify the polymorphism of leptin gene and its association with growth traits in Kebumen Ongole Grade cattle. One hundred blood samples were collected for molecular analysis. Polymorphism of the leptin gene was analyzed using Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP) with HpyCH4V restriction enzyme and DNA sequencing. Association analysis of the leptin gene with growth traits was analyzed by T-test. The results showed that SNP g. 1180 C>T was found in the population.The SNP changed amino acid from arginine to cysteine. The SNP was significantly associated with a high chest circumference at weaning age in animal having CC genotype (P<0.05). There were two identified alleles, namely C and T, with frequencies were 0.885 and 0.115,respectively. The genotype frequencies of CC, CT and TT were 0.78, 0.21 and 0.01, respectively. Allelic and genotypic distribution in the studied population were in Hardy-Weinbergequilibrium. Animals with CC genotype had a higher circumference at weaning age (WCC) than those with CT genotype. In conclusion, SNP g. 1180 C> T in the leptin gene is potential as genetic marker for growth traits in Kebumen Ongole Grade cattle.

Abstract Investigate possible correlations between genetic polymorphisms of IL17A G197A (rs2275913) and IL17F T7488C (rs763780) with the development of keratoconus (KC) in patients from a population of the northwestern part of the State of São Paulo. Were enrolled 35 patients and 61 controls. Genotyping of IL17A G197A and IL17F T7488C polymorphisms was carried out using the PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) technique. The evaluation of IL17F T7488C SNP found that the TT genotype is associated as a risk factor for the development of KC (P = 0.04; OR = 2.97; CI = 1.09–8.33). As for the evaluation of IL17A G197A SNP, the allele and genotype frequencies between patients and controls were compared and no statistically significant differences were found. The TT genotype of IL17F T7488C SNP apparently contributes to the development of KC and the IL17A G197A SNP seemingly has no influence on the progression of the disease in the population of this study.

Genetic susceptibility to tuberculosis has been investigated worldwide, however a few studies conducted in Sudanese patients. Polymorphisms in NRAMP1 have shown an important association with susceptibility to tuberculosis and progression to active disease. However, whether there is an association of these polymorphisms with pulmonary tuberculosis among Sudanese patients is not investigated yet. The aim of this study was to determine the association of NRAMP1 polymorphisms with development of pulmonary tuberculosis in Sudanese subjects with pulmonary tuberculosis. A case-controls study (100 in each arm) was conducted at Al-Shaab Teaching Hospital in Khartoum, Sudan during the period of March through September 2017. Genotyping for NRAMP1 (rs3731865) INTR4 and (rs17235409) D543N was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).There was no significant difference in the mean± SD of the age and body mass index (BMI) between the cases (tuberculosis) and the controls [37.7 ± 4.1 vs. 35.9 ± 3.9 years; P=0.702] and [24.6 ± 1.9 vs. 24.7 ± 2.1; P=0.444], respectively. None of the genotype frequencies investigated in the two polymorphisms were associated with the development of pulmonary tuberculosis. There was a significant association with the development of tuberculosis with illiteracy P=<0.001. Gene polymorphisms of NRAMP1 (rs3731865) INTR4 and (rs17235409) D543N were not associated with pulmonary tuberculosis development in this setting. Further study is needed with larger sample size and different design and settings. Increase public awareness about tuberculosis infections and specially in those who are illiterate.

Colorectal cancer (CRC) is the third most commonly occurring cancer worldwide. Intestinal cells are CYP27B1 gene expression sites and, as a consequence, they are capable of converting pro-vitamin D into the active paracrine and autocrine forms. It was demonstrated that rs10877012 polymorphism in the CYP27B1 gene influenced the circulating vitamin D level. This provided a rationale for determining the role that this polymorphism plays in the risk of developing colon cancer. In this study, we investigated the association of rs10877012 (T/G) polymorphism in the CYP27B1 gene with CRC susceptibility. The study population (n = 325) included CRC patients (n = 106) and healthy controls (n = 219). DNA was extracted from peripheral leukocytes and analyzed for the CYP27B1 polymorphism using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. We found an association between the presence of the T allele at the polymorphic site (odds ratio (OR) = 2.94; 95% CI 1.77–4.86; p < 0.0001) and a decreased CRC incidence.

AbstractStress syndrome is usually caused by a mutation in theryanodine receptorgene(ryr1) and it is widely studied in humans and swine populations. The protein product of this gene plays a crucial role in the regulation of calcium transport in muscle cells. A G>T mutation in the humanryr1gene, which results in the replacement of a conserved arginine at position 614 where a leucine occurs at the same position as the previously identified Arg→Cys mutation reported in all cases of porcine stress syndrome (PSS). Porcine stress syndrome affects biochemical pathways in stress-susceptible individuals during a stress episode and some biochemical parameters that were used as markers for diagnostic purposes. Also, PSS has remarkable influence on the maternal characteristics of sows. This study dealt with different genotypes for PSS and its association with possible biochemical changes and maternal traits of sows. Seventy-three reproductive sows genotyped for PSS by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were included in this survey. Sixty of them were stress-free (NN), 11 were heterozygous carriers (Nn) and two animals were homozygous (nn) for the 1843 (C>T) mutation. Significant differences in non stress induced animals with different PSS genotypes were found in the values of creatine phoshokinase (CPK), lactate dehydrogenase (LDH), alkaline phosphatase (AP) and aspartate aminotransferase (AST). Regarding the maternal traits, our study showed that stress susceptible animals (nn) have an increased number of stillborn piglets and a reduced number of newborn piglets compared with heterozygous and normal animals.

Background: Physical activity is a complex phenotype influenced by millions of genes and environmental factors. It is well known that physical performance and sports ability are linked to genes variations. Objectives: The aim of this study was to evaluate the frequency of PGC1-α and CKMM gene polymorphisms in elite hockey athletes. Methods: Fifty Iranian elite national hockey athletes and 100 non-athletes participated in this study. To determine the genotypes of PGC1-α and CKMM gene polymorphisms, 2 ml of saliva was sampled and used for DNA extraction. To determine the genotypes, the PCR-RFLP method was employed. After examining the variants, the allele and genotype frequencies of subjects were measured. Results: The results showed no significant differences for the PPARGC1A gene in the percentage of AA, GG, and AG genotypes. Similarly, the percentage of these genotypes of the CKMM gene did not differ significantly between athletes and non-athletes. Conclusions: The results suggest that the gene polymorphisms of PGC1-α and CKMM are the same between the Iranian elite hockey athletes and non-athletes, which may be due to the overlapping effect of other genes and/or the small sample size of the study.

Abstract Background Multidrug resistance member 1 (MDR1) is located on chromosome 7 and encodes P-glycoprotein (Pgp), which is universally accepted as a drug resistance biomarker. MDR1 polymorphisms may change either the protein expression or function, suggesting its possible association with cancers, including colorectal cancer (CRC). Thus, this study aimed to determine the effects of MDR1 polymorphisms on the drug response of Saudi CRC patients.Methods DNA samples were obtained from 62 CRC patients and 100 healthy controls. The genotypes and allele frequencies of the MDR1 polymorphisms G2677T and T1236C were determined by polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP).Results No significant difference was observed in the genotype distribution and allele frequency of T1236C between the CRC the patients and the controls. However, G2677T was found to play a highly significant protective role against the progression of CRC. Moreover, the results showed that none of the genotypes in SNPs T1236C and G2677T affected chemoresistance to Xeliri and Xelox.Conclusions T1236C in the MDR1 gene is not related to CRC risk, and G2677T protects against the development of CRC. Both MDR1 polymorphisms are not associated with the risk of chemoresistance.
