<b><i>Introduction:</i></b> Multiple myeloma (MM) is an incurable, biologically heterogeneous disease of the plasma cells, associated with older age and is more common in men. Gaucher disease, caused by mutation in acid β-glucosidase (glucocerebrosidase, <i>GBA</i>) gene, has been linked to multiple cancers, especially MM. Pathological accumulation of glucosylceramide and complex glycosphingolipids coupled with chronic inflammation may be the cause of cancer in patients with Gaucher disease. In this study, we hypothesized patients with MM have mutations in the <i>GBA</i> gene and analyzed patients with MM to determine whether they have a higher frequency of <i>GBA</i> variants. <b><i>Methods:</i></b> Twenty-four MM samples were acquired from the Human Biobank, China Medical University Hospital, Taichung, Taiwan. <i>GBA</i> mutations were detected by polymerase chain reaction-directed DNA sequencing. <b><i>Results:</i></b> We found no mutations in the coding regions of <i>GBA</i> in any of the 24 study subjects. However, two single-nucleotide polymorphisms, rs2070679 and rs2361534, were identified. A significant difference was observed between the study and control groups (<i>p</i> = 0.0028) in rs2361534 allele distribution, with the C allele frequency being higher in patients (1/48, 2.1%) than in the control group (5/3030, 0.16%, Taiwan Biobank). <b><i>Conclusion:</i></b> In this study, the sample size was limited and GBA enzyme activity was not measured; therefore, we could not establish a direct correlation between MM and <i>GBA</i> mutations. However, the association of rs2361534 suggests that regions around this single-nucleotide polymorphism may be involved in MM. The relationship between MM and <i>GBA</i> mutations remains unclear. A large sample is required for a detailed analysis of this potential relationship.

Background and Aims: Programmed cell death-1 (PD-1) has a vital role in regulating T-cell function, and immune escape mechanism of cancer cells. It was shown that there could be a relationship between single nucleotide polymorphisms (SNPs) in the PD-1 gene and susceptibility to hepatocellular carcinoma (HCC) based on various studies. We aimed to investigate the role of three SNPs within the PD-1 gene in susceptibility to HCC in the Turkish population. Methods: Single nucleotide polymorphisms of PD-1.1, 1.5, and 1.6 were genotyped by using TaqMan Allelic Discrimination Assays in blood samples of 137 HCC and 136 control subjects, matched for age and gender. The genotype, allele and haplotype frequencies were compared in HCC and control groups using logistic regression analysis. Results: Genotype distributions of PD-1.1, PD-1.5 and PD-1.6 SNPs were in Hardy-Weinberg equilibrium. No significant difference was observed in the genotype distribution of PD-1.1, PD-1.5 and PD-1.6 polymorphisms among gender and age-matched HCC (M/F: 96/41; mean age: 61.4 ±11.7 years) and control group (M/F: 94/42; mean age: 61.4±10.1). In the haplotype analysis of PD-1.1/PD-1.5/PD-1.6, no significant difference was found among HCC and control group adjusted for sex and age (all p values>0.1). Conclusion: Our findings, firstly reporting the association of PD-1.5 polymorphism with HCC, and PD-1.1 and PD-1.6 with HCC in the Turkish population, suggest that PD-1 polymorphisms are not predisposing factors for HCC development. Future studies with larger sample sizes and different ethnic populations are required to validate our findings.

Apoa5 Gene

Background and aims: The APOA5 gene is one of the genes involved in metabolic syndrome (MetS), as a constellation of several cardiovascular disease (CVD) risk factors. The present study evaluated the possible associations between five single nucleotide polymorphisms (SNPs) in the microRNA target site (miR-TS-SNPs) of the APOA5 gene with MetS. Methods: This case-control study included 57 MetS cases, along with 59 normal children and adolescents aged 9-18 years. All miR-TSSNPs rs188133936, rs72525532, rs45596738, rs148759216, and rs114627122 were genotyped by polymerase chain reaction-sequencing. Independent t-test, as well as the chi-square test and logistic regression analysis was used to determine the association of SNPs with MetS risk and its clinical components. Results: The mean (SD) age of MetS participants and controls was 12.35 (0.25) and 13.39 (0.38) years, respectively. Although no nucleotide changes were present in rs188133936, rs45596738, rs148759216, and rs114627122, a greater frequency of A insertion was detected in rs72525532 in MetS cases compared with the control group (P=0.012). This variant showed a significant difference in triglycerides (TG) and high-density lipoprotein cholesterol (HDL) levels between different genotype groups (P<0.0001 and P=0.05, respectively) in controls. Furthermore, AA insertion genotype was correlated with an increased risk of MetS (Odds ratio [95% CI] = 8.12 [0.966-68.27], P=0.05). Conclusion: This study was the first to investigate the association between rs188133936, rs45596738, rs148759216, rs76463524, and rs72525532 variants of the APOA5 gene and MetS. Our findings reveal that rs72525532 might have an impact on TG, HDL levels, and the risk of MetS

Background: Single Nucleotide Polymorphisms (SNPs) in the Erythropoietin (EPO) promoter region have been shown to influence EPO protein expression, and high blood levels of EPO are associated with an increased risk of brain injury in very preterm infants. Here, we investigated the genotype distributions and association of three EPO gene polymorphisms (rs1617640, rs551238, and rs507392) with the risk of brain injury in preterm infants. Methods: 304 preterm infants with a gestational age of 28 to 34 weeks were enrolled in this study. Brain injury was evaluated by brain ultrasound and MRI examination. EPO gene Single- Nucleotide Polymorphisms (SNPs) were genotyped by the Agena MassARRAY system, and their association with brain injury susceptibility in preterm infants was analyzed. Results: EPO polymorphism rs551238 showed a significant difference in the genotypic distributions between the brain injury group and the control group, and was significantly correlated with reduced susceptibility to brain injury in preterm infants according to the results obtained from both the additive model (OR = 0.520, 95% CI: 0.339-0.799, P = 0.003) and the dominant model (OR = 0.523, 95% CI: 0.332-0.853, P = 0.009). EPO polymorphisms rs1617640 and rs507392 did not meet the Hardy-Weinberg equilibrium in the study population (P < 0.05) and were, thus, not subjected to further analysis for their impacts on brain injuries. Conclusion: The “C” allele of rs551238 was correlated with a reduced risk of brain injury in preterm infants which may serve as a potential marker for brain injury prediction in preterm infants.

Abstract Background CCN1 plays a crucial role in the modulation of cardiovascular diseases. However, whether CCN1 genetic variants are involved in the susceptibility of ACS remains unknown. Hence, the present study investigates the association between CCN1 polymorphisms and ACS among Han and Uygur populations in Xinjiang, China. Results In this case-control study, 1234 Han (547 ACS patients and 687 controls) and 932 Uygur (471 ACS patients and 461 controls) were genotyped using SNPscanTM for three single-nucleotide polymorphisms (SNPs, rs6576776, rs954353, and rs3753794) of the human CCN1 gene. In the Uygur population, we found that the detected frequencies of the C allele (25.3% vs. 18.3%, P<0.001) and CC genotype (6.4% vs. 3.0%, P=0.001) of rs6576776 were significantly higher in the ACS patients than in the control participants. Differences in rs6576776 regarding the dominant model (CC+CG vs. GG, 44.2% vs. 55.8%, P=0.001) and the recessive model (CC vs. CG+GG, 6.4% vs. 93.6%, P=0.016) were observed between the two groups. The frequencies of the GGC and AGC haplotypes in those with ACS were significantly higher than those in the control group (all P<0.05) in the Uygur population. After adjusting for hypertension, diabetes, lipids and smoking, all of which indicate that the rs6576776 C allele is associated with higher risk of ACS (odds ratio (OR)=1.798, 95% confidence interval (CI), 1.218-2.656, P=0.003). In Han population, neither the distribution of genotypes and alleles of the CCN1 gene three SNPs nor the distribution of haplotypes constructed with the three SNPs exhibited a significant difference between the ACS patients and control participants. Conclusions Our study document that the CCN1 gene rs6576776 C allele is associated with higher susceptibility of ACS and that the frequencies of GGC and AGC haplotypes are higher among the Uygur ACS patients.

Abstract Background Egypt has the highest hepatitis C virus prevalence worldwide where about 24% of the people are estimated to carry HCV and more than 50% of blood donors have anti-HCV in some towns. The burden of hepatocellular carcinoma has been increasing in Egypt with a doubling in the incidence rate in the past 10 years. Thus, the aim of the present study was to analyze the interleukin-18 single nucleotide polymorphisms (SNPs) as a diagnostic tumor marker for hepatocellular carcinoma in patients with hepatitis C-related cirrhosis. Results This study included 33 hepatocellular carcinoma (HCC) complicating HCV-related cirrhosis patients, 37 cirrhotic patients without HCC (cirrhosis group), and 20 healthy individuals who were included as a control for 9 months of follow-up. SNPs of the IL-18 gene were genotyped by polymerase chain reaction. There was a statistically significant difference in the GG genotype in the HCC group in comparison with the control group (P = 0.04). There was a statistically significant difference in the G allele in the cirrhosis and HCC groups in comparison with the control group (p1 < 0.001 and p2 = 0.03, respectively). Patients with GC genotype have a risk for developing HCC by 6.33-folds more than those with GG genotype while patients with GC genotype have a risk for developing cirrhosis by 5.43-folds more than those with GG genotype, and cirrhotic patients with CC and GC genotype had a risk for developing HCC by 1.17-folds more than those with GG genotype. Conclusion Our findings revealed that the analysis of IL-18 single nucleotide gene polymorphism could be a valuable marker for the prediction of progress towards cirrhosis in chronic HCV patients and also to subsequent development of HCC in HCV cirrhotic patients proved by the results of both GG genotype and its G allele; also, cirrhotic patients with CC and GC genotype have a risk for developing HCC by 1.17-folds more than those with GG genotype.

Marrow Fibrosis

Abstract Introduction Multiple myeloma (MM) is characterized by the proliferation of plasma cells in the bone marrow and a secretion of monoclonal immunoglobulins. Survival in MM is very variable and multiple factors are known to influence prognosis such as age, ISS stage, and genetic abnormalities. Fibrosis can be found in the bone marrow of MM patients but the literature reporting the incidence of fibrosis and its effect on prognosis is very limited. The purpose of this study was to estimate the incidence of bone marrow fibrosis in MM patients and its effect on survival. Materials and methods Data was collected at the Karolinska University Hospital in Solna, Sweden and information obtained from the hospital's records. We gathered information on all patients diagnosed with MM between 2003 and 2011. All bone marrow reports were reviewed and the presence of bone marrow fibrosis (evaluated using reticulin staining) at diagnosis was recorded. Fibrosis was graded as 1 (mild), 2 (significant) and 3 (advanced), in accordance with WHO 2008 criteria. Patients with fibrosis were paired with patients without fibrosis (matched by sex, birth year, and year of diagnosis). Survival comparing MM patients with and without fibrosis was evaluated using Kaplan-Meier estimate and Cox regression model. Results A total of 586 individuals, 327 males and 259 females, were diagnosed with MM at the Karolinska University Hospital, Solna during 2003 – 2011. Evidence of bone marrow fibrosis was noted in 223 (38%) patients at diagnosis, and 175 had fibrosis grade 1, 33 grade 2, and 15 grade 3. No significant difference was observed between males (N = 135) and females (N = 88) (p = 0.085). Mean age at diagnosis was significantly lower for patients with fibrosis (67.1 years) than in patients without fibrosis (69.7 years) (p = 0.013). Compared with paired patients without fibrosis (N = 217), patients with fibrosis had significantly worse survival (Figure), being 5.0 years vs. 4.4 years, respectively (relative risk (RR)=1.3, 95% confidence interval (CI) 1.00-1.70; p= 0.049). The difference was greatest in male patients and patients younger than 65 years at diagnosis. Survival was worse in patients with advanced fibrosis, 4.5 (95% CI 3.6-6.4) years for grade 1 fibrosis, and 3.0 (95% CI 1.6-NA) years for higher degree of fibrosis. Conclusion In this study, based on almost 600 patients with MM we show that bone marrow fibrosis is common at diagnosis (38%). Importantly, our findings show that the presence of fibrosis was associated with inferior survival. More studies are needed regarding the underlying causes for these findings, including treatment response, treatment-related complications and relation to other known prognostic factors.

Introduction. Inflammation of the meninges can have various clinical courses, from mild, self‑limiting in some viral neuroinfections to severe, sometimes ending in death. The pro‑inflammatory cascade and defects in the inhibitors of the inflammatory response play an important prognostic role. Single nucleotide polymorphisms (SNPs) of the genes encoding cytokines, influence the severity of the inflammatory response.Aim. The aim of this study was to evaluate the effect of selected polymorphisms of proinflammatory cytokines IL-1β, TNF‑α and IL-8 on the development of neuroinfections.Material and Methods. We evaluated the laboratory results of 30 patients treated for bacterial and viral meningitis and compared those to 30 healthy volunteers. The following 4 variants were analyzed for occurrence of genetic polymorphism in patients with meningitis versus the control group: IL-1β 3953, IL-1β -31, TNF‑α -308, and IL-8 781. Then, we assessed the association between these genetic polymorphisms and the inflammatory response during the course of meningitis.Results and Conclusions. We observed that polymorphism of the IL-1β-31 significantly differs between patients and healthy subjects, the IL-1β -31AA polymorphism existed only in healthy individuals (p < 0.001). The WBC count was dependent on the TNF‑α -308 polymorphism with a statistically significant difference (p = 0.021) occurring among persons with variants AA and AG. In conclusion the study showed that the presence of the AA genotype of IL-1β-31polymorphism may have a protective effect on the development of meningitis. This polymorphism was not observed in any patient with meningitis.

To observe and evaluate the correlation between single-nucleotide polymorphisms (SNPs) and messenger RNA (mRNA) level related to tristetraprolin (TTP) in Chinese rheumatoid arthritis (RA). TapMan SNP was used for genotyping analysis in 580 RA patients and 554 healthy people. Association between TTP gene polymorphisms (rs251864 and rs3746083) and RA was obtained. Quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) technology was applied for the detection of TTP mRNA level in peripheral blood mononuclear cells (PBMCs) in 36 RA patients and 37 healthy people. We observed that the allele T of TTP rs3746083 increased RA susceptibility (p = 0.019). A significant difference was found under the dominant model of rs3746083 (p = 0.037). Further analysis showed the allele distribution of rs3746083 was nominally correlated with RF phenotype of RA patients (p = 0.045). Nevertheless, the association between TTP rs251864 and the incidence of RA was no statistically significant (p &gt; 0.05). The TTP expression level in PBMCs of RA patients was significantly reduced (p &lt; 0.001). In conclusion, the results of this experiment support that TTP may be involved in the pathogenesis of RA.

Background: This study assessed gene polymorphisms of the CD14 receptor (C-159T) and Toll-like receptor 4 (Asp299Gly) in a patient population in Crimea, Ukraine, stratified by clinical (early versus late onset; frequent versus occasional relapses; fixed versus reversible obstruction) and immunologic (atopic versus nonatopic; eosinophilic; neutrophilic or paucigranulocytic inflammation) subtype. Methods: Two polymorphisms, CD14 C-159T and TLR4 Asp299Gly, were assessed in 331 patients with asthma. The control group included 285 volunteers who were nonatopic. The single nucleotide polymorphisms were studied by using polymerase chain reaction with electrophoretic detection. Results: There were increased odds of asthma development in patients with the Asp299Gly TLR4 mutation compared with the general population underdominant odds ratio (OR) 1.52 [95% confidence interval (CI), 1.00‐2.32] and overdominant (OR 1.55 [95% CI, 1.01‐2.38]) models after adjustment for gender and age. In addition, mutations in this gene decreased the odds of nonatopic asthma in underdominant (OR 0.26 [95% CI, 0.07‐0.93]; p = 0.027), overdominant (OR 0.27 [95% CI, 0.07‐0.96]; p = 0.033), and log-additive models (OR 0.26 [95% CI, 0.07‐0.93]; p = 0.026) compared with the atopic subgroup after adjustment for gender, age, number of exacerbations, and type of airway inflammation. Allele frequencies for CD14 and TLR4 polymorphisms did not show statistical differences between the patients with asthma and the control subjects. Conclusion: CD14 C-159T polymorphisms were not associated with asthma in the adult population in Crimea. TLR4 Asp299Gly polymorphisms were associated with asthma and with decreased odds of nonatopic asthma compared with atopic asthma in the adult population in Crimea.
