Autoimmune thyroid disease (AITD) comprises Graves' disease (GD) and Hashimoto's thyroiditis (HT). IL37 has been recently proved to be a natural suppressor for innate immunity and acquired immunity. Therefore, this study was conducted to identify the association of IL37 genetic polymorphisms with AITD in Chinese Han population. Polymorphisms of rs3811046/rs3811047/rs2723176/rs272186 in the IL37 gene were assessed in a case–control study comprising 701 GD patients, 301 HT patients and 939 controls. Genetic variants were genotyped by multiplex polymerase chain reaction and ligase detection reaction. The frequencies of the minor allele A of rs2723176 and A of rs2723186 were significantly lower in the GD patients than in the controls (P=0.014, OR=0.774; P=0.014, OR=0.777). After gender stratification, the rs3811046 G allele and the rs3811047/rs2723186 A allele were both significantly associated with a decreased risk of GD in female patients (P=0.030, OR=0.777; P=0.023, OR=0.774; P=0.029, OR=0.761). However, none of the four single nucleotide polymorphisms of IL37 gene showed any significant association with HT. Moreover, haplotype analysis revealed the GCG haplotype conferred increased risk for GD as a whole and in female GD patients (OR=1.213; OR=1.320). The ACG haplotype was associated with an increased risk of HT as a whole (OR=1.567) and in male GD patients (OR=1.820). In contrast, the AAA haplotype showed a protective role for GD as a whole (OR=0.760) and in female GD patients (OR=0.765). Our study strongly supports that the IL37 gene variants are associated with the susceptibility to AITD.

Objective: The aim of this study was to investigate UBASH3A gene variation association with autoimmune thyroid disease and clinical features in a Chinese Han population. Subjects and methods: A total of 667 AITD patients (417 GD and 250 HT) and 301 healthy controls were genotyped for two single nucleotide polymorphisms (SNPs) rs11203203, rs3788013 of UBASH3A gene, utilizing the Matrix Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometer (MALDI-TOF-MS) Platform. Results: Between the control group and AITD, GD and HT group, no statistically significant difference was observed in the genotypic and allelic frequencies of the two SNPs. There was no significant difference in allelic frequencies of the two SNPs between GD with and without ophthalmopathy. There was no significant difference in haplotype distributions between the control group and AITD, GD or HT group. Conclusion: Rs11203203 and rs3788013 in UBASH3A gene may not be associated with AITD patients in Chinese Han population.

Abstract Background: Autoimmune thyroid diseases (AITDs) are female predominant and the biology of sexual dimorphism is not clearly understood. Recently, GPR174 and ITM2A on X chromosome have been newly suggested as autoimmune thyroid disease susceptible loci. Methods: Fourteen single nucleotide polymorphisms in immune related genes on X chromosome were analyzed in 108 Korean children (girls =90, boys =18) with AITD [Hashimoto disease (HD) = 40, Graves′ disease (GD) = 68, thyroid-associated ophthalmopathy (TAO) = 37, and non-TAO =60] with gender ratio matched normal control 106 controls (female = 43, male = 63). Results: In AITD, the frequencies of GPR174 rs3810711 T allele (OR=6.0, cP =0.000), GRP174 rs3827440 T allele (OR=6.0, cP =0.000), ITM2A-GPR174 rs5912838 A allele (OR=2.7, cP =0.001) were increased and of GPR174 rs3810711 CC genotype (OR=0.2, cP =0.000), GRP174 rs3827440 CC genotype (OR=0.2, cP =0.000), ITM2A-GPR174 rs5912838 CC genotype (OR=0.4, cP =0.000)were lower than controls. In GD, the frequencies of GPR174 rs3810711 T allele (OR=8.4, cP =0.000), GRP174 rs3827440 T allele (OR=8.4, cP =0.000), ITM2A-GPR174 rs5912838 A allele (OR=3.3, cP =0.000) were increased and GPR174 rs3810711 CC genotype (OR=0.1, cP =0.000), C allele (OR=0.5, cP =0.044), GRP174 rs3827440 CC genotype (OR=0.2, cP =0.000), C allele (OR=0.5, cP =0.044), ITM2A-GPR174 rs5912838 CC genotype (OR=0.4, cP =0.000) were lower than controls. In HD, the frequencies of GPR174 rs3810711 T allele (OR=3.9, cP =0.003), GRP174 rs3827440 T allele(OR=3.9, cP =0.003) were increased and GPR174 rs3810711 CC genotype (OR=0.3, cP =0.004), rs3827440 CC genotype (OR=3.9, cP =0.003) were lower than controls. In thyroid-associated ophthalmopathy, the frequencies of GPR174 rs3810711 T allele (OR=7.9, cP =0.000), GRP174 rs3827440 T allele (OR=7.9, cP =0.000), ITM2A-GPR174 rs5912838 A allele (OR=3.1, cP =0.001) were increased and of GPR174 rs3810711 CC genotype (OR=0.1, cP =0.000), GRP174 rs3827440 CC genotype (OR=0.1, cP =0.000), ITM2A-GPR174 rs5912838 CC genotype (OR=0.3, cP =0.014)were lower than controls. Conclusions. Our results suggest that polymorphisms of GPR174 and ITM2A genes on X chromosome might contribute to the pathogenesis of AITD.

Abstract We aimed to study the relationship between rs11174811 and rs3803107 single nucleotide polymorphisms (SNPs) in miRNA target sites of the 3′ UTR in the arginine vasopressin receptor 1a gene (AVPR1A) and the risk of hypertension in the Chinese Han population. The genotypes at rs11174811 and rs3803107 were analyzed by direct sequencing in 425 Chinese Han patients with hypertension and 425 healthy subjects. AVPR1A expression was investigated by transfecting miR-526b, miR-375, and miR-186 mimics into human umbilical vein endothelial cells (HUVECs) containing AVPR1A rs11174811 CC, CA/AA and AVPR1A rs3803107 GG, GA/AA genotypes. The A alleles of rs11174811 (adjusted OR = 1.424, 95% CI: 1.231–1.599, P<0.001) and rs3803107 (adjusted OR = 1.222, 95% CI: 1.092–1.355; P=0.001) were high risk factors for hypertension. Plasma levels of miR-526b, miR-375, and miR-186 were higher in the study group than in the control group (P<0.001). The expression levels of AVPR1A mRNA in AVPR1A rs11174811 and rs3803107 mutant HUVECs were higher than those in wild-type cells (t = 8.811, 4.068 and P=0.001, 0.015, respectively). The single nucleotide polymorphisms rs11174811 and rs3803107 in the AVPR1A gene are associated with an increased risk of hypertension in the Chinese Han population. This may be related to the effect of these variants on the regulation of AVPR1A expression by miRNAs.

Objective. Osteoarthritis (OA) is a complex arthritic condition in which the genetic factor plays a major role. One of the candidate genes of is the ADAM12 gene, but no consistency has been reached till now. This study aims to investigate the potential role of four single nucleotide polymorphisms (SNPs) of the ADAM12 gene in susceptibility to knee OA and its progression in Chinese Han population.Methods. The rs1278279, rs3740199, rs1044122, and rs1871054 polymorphisms were genotyped and compared in a population based cohort consisting of 164 OA subjects and 200 age- and gender-matched controls.Results. The SNP rs1871054 was found with increased risk of OA susceptibility in comparing the genotype frequencies between the case and control groups no matter for which model of comparison (allele level, dominant model, recessive model, and extreme genotype model). Additionally, the SNP rs1871054 was found associated with increased OA severity according to the K/L grade.Conclusion. In summary, we have identified that the rs1871054 variant within the ADAM12 gene is a risk factor for increased osteoarthritis susceptibility and severity.

The association between vitamin D receptor (VDR) polymorphisms (rs731236, rs1544410, rs2228570, and rs7975232) and the risk of autoimmune thyroid disease (AITD) had been investigated in previous studies. However, the results of these studies remained controversial. Thus, a meta-analysis was performed to derive a more precise conclusion. All related articles were systematically searched by PubMed, Embase, Google Scholar, and Chinese National Knowledge Infrastructure (CNKI). The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of association. The overall results indicated thatVDRrs731236 and rs2228570 polymorphisms were significantly associated with a reduced risk of AITD. However, a stratification analysis based on clinical types showed thatVDRrs731236 and rs2228570 polymorphisms were associated only with a reduced risk of HT. A stratification analysis by ethnicity showed thatVDRrs731236 polymorphism was significantly associated with a reduced risk of AITD in Asian and African populations.VDRrs2228570 polymorphism was associated with a reduced risk of AITD in Asian populations.VDRrs1544410 polymorphism was associated with a reduced risk of AITD in European and African populations, but with an increased risk of AITD in Asian populations.VDRrs7975232 polymorphism was significantly associated with an increased risk of AITD in African populations. In conclusion, the present study suggested thatVDRrs731236, rs1544410, rs2228570, and rs7975232 polymorphisms were significantly associated with AITD risk. However, more well-designed studies should be performed to verify the current results.

67 Background: Nasopharyngeal Carcinoma(NPC) is an Epstein-Barr virus(EBV) associated malignancy with remarkable ethnic and geographical distribution. The EBV oncoprotein latent membrane protein 1 (LMP1) is the primary oncogene of EBV infection through the its signaling cascade and its connections to other pathways including NF-κB, TGF-β and JNK signaling, which plays an important role in the pathogenesis of NPC. In GWASs (Genome-wide association studies) associations these pathways were also identified. Single nucleotide polymorphisms (SNPs) in the regulatory regions may regulate the expression of genes in these pathways, or affect the function of the coded protein. Methods: Altogether 149 SNPs were covered by the 15 SNPs in the TRAF2, TRAF3, NFKBIA, MAP2K4, and CHUK genes were genotyped in a hospital-based case-control study of 350 NPC cases and 587 healthy controls from the Chinese Han. The observed genotype frequencies in the controls were tested for Hardy–Weinberg equilibrium (HWE) using the chi-square test. Odds ratios (ORs) and 95% confidence intervals (95% CIs) for associations between genotypes and NPC risk and tumor characteristics were calculated by logistic regression, and they were adjusted for multiple testing using the SNP spectral deposition (SNPSpD) approach for multilocus analyses. Results: We found one NFKBIA SNP was associated with NPC risk after adjustment for multiple comparisons. Minor allele carriers of the NFKBIA had an increased risk of NPC (P 0.05). The analyses were adjusted for age and gender. For a polymorphism with a variant allele frequency between 10 %and 50%, the study had greater than 90% power to detect an OR of 1.50 at a significance level of 0.05 (PS—software for power and sample size calculation, http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/PowerSampleSize). The other genotyped SNPs that we found were not associated with NPC risk. Conclusions: Our data suggests that genetic variation especially in the NFKBIA maybe a useful biomarker for NPC screening and further studies are warranted.

Abstract Purpose LRRC3B gene, as a tumor suppressor gene was involved in the development and progress of breast cancer (BC). However, the effect of LRRC3B polymorphisms on BC has rarely been reported. In the study, we aims to evaluate the relation between LRRC3B variants and BC risk. Methods Among 563 BC patients and 552 healthy controls, ten single-nucleotide polymorphisms (SNPs) in LRRC3B were genotyped by Agena MassARRAY. Odds ratios (OR) and 95% confidence interval (CI) was calculate using logistic regression model. Results Our study demonstrated that rs1907168 polymorphism (OR = 0.71, p = 0.017) reduced the risk of BC in the overall. In stratified analyses by age, rs1907168 decreased (OR = 0.53, p = 0.002) while rs78205284 (OR = 2.83, p = 0.034) increased BC susceptibility among the population at age ≤ 51 years. Clinical parameters such as tumor size, the status of PR and Ki67 were associated with LRRC3B variants. Furthermore, we found that the association of ‘GATT’ haplotype with an increased risk for BC. In addition, LRRC3B gene was down-regulated in BC tumor and had a poor prognosis in BC in silico analysis. Conclusion Our study firstly found LRRC3B SNPs contributed to the risk of BC, suggesting LRRC3B variants might help to predict BC progression.
