Correlation between single nucleotide polymorphism of FCRL-3 gene and Graves' disease in Han population of northern Anhui province, China.

ABSTRACT: OBJECTIVE:The frequency distribution of A/G genotype at position-169 in promoter of FCRL3 gene (Fc receptor-like 3) was identified in Han population of northern Anhui Province. The correlation between single nucleotide polymorphism (SNP) at this site and genetic susceptibility of Graves disease (GD) was discussed. How the genotype at this position correlated to age, gender, severity of goiter, presence or absence of exophthalmos, levels of thyrotrophin receptor antibody (TRab), thyroid peroxidase antibody (TpoAb) and anti-thyroglobulin antibody (TgAb) and thyroid function was analyzed in details. METHOD:Peripheral venous blood was collected for DNA extraction. SNP at position-169 in the promoter of FCRL3 gene was determined by using PCR-RELP among 180 GD cases and 146 normal subjects. Thyroid function tests and antibody detection were performed. RESULTS:The frequency of GG genotype of position-169 in promoter of FCRL3 gene was higher in GD group than in control group. The frequency was 28.9% and 13.8%, respectively, showing significant differences in intergroup comparison (?(2)=6.618, P=0.046). The G allele frequency of GD group and control group was 49.4% and 40.4%, respectively, also showing significant differences between the groups (?(2)=5.308, P=0.021). GD cases with AA, AG and GG genotypes at position-169 in FCRL3 promoter had significant differences in serum level of TRAb (?(2)=7.319, P=0.026). However, no significant differences in gender, severity of goiter, TpoAb and TgAb level, presence or absence of exophthalmos and thyroid function (FT3, FT4, TSH) were found between the three genotypes (P>0.05). CONCLUSION:A/G SNP at position-169 in promoter of FCRL3 gene was correlated with susceptibility to GD among Han population in northern Anhui Province. G allele may contribute to the susceptibility to GD and correlate to positive TRAb result in thyroid diseases, but not to age of onset, gender, presence or absence of exophthalmos, thyroid function, TpoAb and TgAb level or severity of goiter.

Project description:BackgroundAnhui Province in China is facing a severe HIV epidemic with an increasing number of newly diagnosed cases.MethodsIn this study, HIV genetic characteristics in the province were investigated. Newly reported HIV-positive individuals from 15 districts of Anhui Province were enrolled and interviewed. Total viral RNA was extracted from plasma isolated from blood samples. We amplified and sequenced an HIV pol fragment of the 1062 bp. The sequences were used for determination of HIV subtypes and the presence of drug resistance mutations. Transmission networks were constructed to explore possible relationships. And all of assembled partial pol genes were submitted to the Stanford HIV Drug Resistance Database website to find the transmitted drug resistance.ResultsPartial pol gene sequences were obtained from 486 cases. The results showed that MSM was the most dominant transmission route (253, 52.06%), followed by heterosexual transmission (210, 43.21%) and blood-borne transmission (1, 0.21%). Many subtypes were identified, including CRF01_AE (226, 46.50%), CRF07_BC (151, 31.07%), subtype B (28, 5.76%), CRF08_BC (20, 4.12%), CRF55_01B (15, 3.09%), CRF68_01B (7, 1.44%), CRF67_01B (3, 0.62%), CRF57_BC (2, 0.41%), CRF59_01B (2, 0.41%), CRF79_0107 (2, 0.41%), subtype C (2, 0.41%), CRF64_BC (1, 0.21%), and circulating recombinant forms (URFs) (27, 5.55%). Four transmission subnetworks containing high transmission risk individuals (with degree ≥4) were identified based on CRF01_AE and CRF07_BC sequences, including two CRF01_AE transmission subnetworks constituted by elderly people with average ages of 67.9 and 61.5 years. Infection occurred most likely through heterosexual transmission, while the other two CRF07_BC transmission subnetworks consist mainly of MSMs with average ages of 31.73 and 34.15. The level of HIV-transmitted drug resistance is 3.09%.ConclusionsThe simultaneous spread of multiple HIV subtypes in Anhui province underscores that close surveillance of the local HIV epidemic is necessary. Furthermore, the elderly people were frequently involved, arguing for behaviour intervention in this specific population besides the MSM risk group.

Project description:Hypoxia inducible factor-1? (HIF-1?) is associated with the progression and metastasis of lung cancer. There are, however, few studies on the relationship between the single nucleotide polymorphisms of HIF-1? and susceptibility to lung cancer. Therefore, we aimed to investigate the relationship between indoor air pollution, HIF-1? rs2057482, and the susceptibility to primary lung cancer of the Fujian Han population.The present study is a hospital-based case-control study. We recruited 1,096 lung cancer and 1,110 controls that were admitted to the Department of Thoracic Surgery of the First Affiliated Hospital and Union Hospital of Fujian Medical University and Fuzhou General Hospital of Nanjing Military Region from January 2006 to December 2012. The primary lung cancer cases were identified via pathological methods. Both case and control groups received questionnaires. Genotyping of HIF-1? gene rs2057482 locus polymorphism in all subjects were analyzed by MALDI-TOF-MS technique.Individuals who carried the T-genotype of HIF-1? rs2057482 were more susceptible to small cell carcinoma (odds ratio of 1.725, 95%CI: 1.047-2.842). After adjusting for general and lung cancer-related factors, we found that in the co-dominant genetic model, rs2057482 TT carriers were 2.195 times more likely to develop lung cancer than CC carriers (95%CI: 1.038-4.463) in the population that were exposed to passive smoking. In the dominant genetic model, the risk of lung cancer was 1.911 times (95%CI: 1.121-3.258) that in the carriers of the rs2057482 T allele with a family history of cancer. In the recessive genetic model, rs2057482 TT carriers had a 0.159-fold increased risk of lung cancer (95%CI: 0.028-0.920) than TC+CC carriers in people with a history of lung disease. In the additive genetic model, the risk of lung cancer in rs2057482 TC+TT carriers was 1.542 times (95%CI: 1.107-2.340) that in the CC family of people with a family history of cancer.HIF-1? rs2057482 may be associated with lung cancer susceptibility.?.
