ABSTRACT
Objective To investigate thecorrelation between nonmusle myosin heavy chain 9 gene (MYH9) rs12107,signal transducer and activator of transcription (STAT4) rs3024912, Urokinase plasminogen activator (uPA) rs4065 single nucleotide polymorphism and idiopathic Uighur membranous nephropathy (IMN). Methods Patients admittedby People′s Hospital of Xinjiang Uyghur Autonomous Region from June 2011 to May 2015 were selected in the research,of which 45 with IMN (group A),45 patients with IgA nephropathy (group B) and 45 healthy controls(group C). The polymorphisms of rs12107,rs3024912 and rs4065 were measured with direct sequencing, in order to analyzing the correlation between genotype and allele with IMN. Results Group Ars12107 (MYH9) locus genotype CC, C allele (48.9%, 65.6%) frequency were higher than those in group B (13.3%, 33.3%) and group C (20.0%, 46.7%), and the difference was statistically significance (P 0.05). rs3024912 GG genotype patients showed higher risk of renal failure compared with non-GG genotype patients (95% CI:1.48-26.83, P = 0.013). Only TT genotype was detected on rs4065 locus. TC and CC genotype were not detected. Conclusions MYH9 gene rs12107 locus CC genotype and C allele are associated with susceptibility to IMN in Xinjiang Uygur, and CC genotypes associated with renal function. rs3024912 (STAT4)GG genotype are not susceptibility gene,but associated with renal function in patients with IMN.
ABSTRACT
Objective To investigate the association between glutamate receptor-6 (GIuR6/GRIK2) gene polymorphism and domestic violence in Xinjiang Uygur population on alcoholics.Methods The methods of polymerase chain reaction (PCR) and DNA sequencing technique were conducted to detect rs6922753 and rs2227283 single nucleotide polymorphism of GLUR6 gene in a 104 domestic violence perpetrators on alcoholics and 80 non-domestic violence perpetrators on alcoholics.The association between the polymorphisms and violent behavior was analyzed with SPSS 17.0.Results The frequency of allele (x2 =4.935) and genotype (x2 =7.622) of rs6922753 polymorphisms in the domestic violence group were statistically different from those in the non-domestic violence group (P ＜ 0.05),there was no significant difference between two groups in allele frequencies and genotype in rs2227283 site (P ＞ 0.05).Conclusions GIuR6 gene polymorphism may be associated with domestic violence in Xinjiang Uygur population on alcoholics.
ABSTRACT
Objective To measure the expressions of Kaposi′s sarcoma-associated herpesvirus type 8 associated-microRNAs k12-1 (kshv-miR-k12-1)and k12-12 (kshv-miR-k12-12)in Kaposi′s sarcoma tissue, and to assess their relationship with pathological stage and lesion area of Kaposi′s sarcoma, HIV infection, and human herpesvirus type 8 (HPV-8)infection. Methods Totally, 18 paired tissue specimens stored in liquid nitrogen from Kaposi′ s sarcoma lesions and paralesional skin were collected. Total RNAs were extracted from these specimens by using Trizol reagent, and reversely transcribed into cDNA. SYBR Green real-time fluorescence-based quantitative PCR was performed to measure the expressions of kshv-miR-k12-1 and kshv-miR-k12-12 in these specimens. The relationship of kshv-miR-k12-1 and kshv-miR-k12-12 expressions with the pathological stage and lesion area of Kaposi′s sarcoma, HIV and HPV-8 infections was analyzed. Results Compared with paralesional normal skin, Kaposi′s sarcoma lesions showed significantly increased expressions of kshv-miR-k12-1 (2-ΔΔCt: 1.016 ± 1.645 vs. 0.029 ± 0.019, t = 2.542, P = 0.016)and kshv-miR-k12-12 (2-ΔΔCt: 2.104 ± 1.973 vs. 0.102 ± 0.093, t = 4.301, P = 0.000). There were no significant differences in the expressions of kshv-miR-k12-1 or kshv-miR-k12-12 between patients with HIV or HPV-8 infection and those without, among patients with different pathological stages of Kaposi′s sarcoma, or among patients with different lesion areas (all P > 0.05). Conclusion Both kshv-miR-k12-1 and kshv-miR-k12-12 are highly expressed in Kaposi′s sarcoma, but neither of their expressions is related to HIV or HPV-8 infection, pathological stage or lesion area of Kaposi′s sarcoma.
ABSTRACT
Objective To investigate the expression differences of MiR-34a/c in lesions of psoriasis vulgaris Uyghur and Han patients and beside-lesional tissue and normal skin tissue in XinJiang.Methods Real-time fluorescent quantitative polymerase chain reaction (PCR) was used to determine the expression levels of MiR-34a/c in the psoriasis vulgaris Uyghur and Han patients with lesion tissues, beside-lesion tissues, and normal skin tissues, respectively.Results The expression level of MiR-34a was higher in lesions of psoriasis vulgaris in XinJiang than in the beside-lesion tissues and normal skin tissues, and differences were statistical significance (P ＜ 0.05).However, the expression level of MiR-34a in beside-lesion tissues and normal skin tissues, and in the Uyghur and Han psoriasis vulgaris werent statistically significant difference (P ＞ 0.05).The expression level of MiR-34c in three types of tissues and in the Uyghur and Han psoriasis vulgaris weren't statistically significant difference (P ＞ 0.05).Conclusions MiR-34a might participate in the pathogenesis of Uyghur and Han psoriasis vulgaris in XinJiang.
ABSTRACT
Objective To explore the genetic association of C1GALT1 gene polymorphisms with susceptibility and prognosis of IgA nephropathy (IgAN) on Uyghur population in Xinjiang Uyghur Autonomous Region.Methods Ninety Uighur patients with IgAN and ninety geographically and age matched healthy controls were recruited.Peripheral blood was collected from recruited individuals for DNA extracting.After amplified by polymerase chain reaction (PCR),genotyping of the four single nucleotide polymorphisms (SNPs) in C1GALT1 gene,which were rs9639031,rs5882115,rs1008898,-527A/G,were detected by direct sequencing analysis.Differences of allele and genotype frequency were analyzed between IgAN and healthy controls.Moreover,the association between these SNPs and the risk and progress in IgAN patients were further analyzed.Results (1) The I allele frequency of rs5882115 in C1GALT1 gene was significantly higher in IgAN than that in healthy controls （x2 =7.788,P =0.015),no difference in allele frequencies of rs9639031,rs1008898,-527A/G between IgAN and healthy controls was found.Under the dominant mode,the DI+ Ⅱ genotype frequencies of rs5882115 was significantly higher in IgAN than that in healthy controls (x2 =8.563,P =0.009),no difference in genotype frequencies of rs9639031,rs1008898,-527A/G between IgAN and healthy controls was found.Under the hidden mode,no difference in genotype frequencies of rs5882115,rs9639031,rs1008898,-527A/G between IgAN and healthy controls was found.Logistic single factor regression analysis showed that the risk to IgAN of whom carry I allele of rs5882115 was 2.469 times than the D allele (OR =2.469),and the risk to IgAN of whom carry DI+ Ⅱ genotype was also higher (OR =2.852).(3) No association was found between these SNPs in C1GALT1 gene and serum creatinine in IgAN.Conclusion Association between rs5882115 in C1GALT1 gene and Uighur IgAN susceptibility suggests that there may be variants in C1GALT1 gene or its linked genetic region,which needs further exploration.
ABSTRACT
Objective To investigate the effects of the interaction between environmental factors and monoamine oxidase A (MAOA) gene polymorphism in Han and Uygur on alcoholics in Xinjiang. Methods The data of childhood abuse and domestic aggressive behaviors were collected from 284 patients with alcohol dependence from Xinjiang using self-made questionnaires, Modified Overt Aggression Scale (MOAS) and Barratt Impulsivity Scale-11 (BIS-11). The meth?ods of PCR and DNA sequencing technique were conducted to detect rs1137070 single nucleotide polymorphism loci of MAOA gene. Logistic regression analysis was performed to adjust for interaction effects of gene and childhood abuse on domestic violence. Results The scale evaluation identified 143 patients with and 138 patients without domestic violence. Childhood abuse and gene were both risk factors in domestic violence. The interaction effect of childhood abuse with rs1137070 was significant. the relative excess risk, the interaction attribution ratio and the interaction index were 1.00,0.14 and 1.20, respectively. Conclusions The interactions between genes and environmental risk factors may contribute to the domestic violence in Han and Uygur on alcoholics in Xinjiang.
