| 1 | ITGA1 polymorphisms and haplotypes are associated with gastric cancer risk in a Korean population显示文摘AIM:To evaluate the association between the geneticpolymorphisms and haplotypes of the ITGA1 gene and the risk of gastric cancer.METHODS:The study subjects were 477 age-and sex-matched case-control pairs.Genotyping was performed for 15 single nucleotide polymorphisms(SNPs)in ITGA1.The associations between gastric cancer and these SNPs and haplotypes were analyzed with multivariate conditional logistic regression models.Multiple testing corrections were carried out following methodology for controlling the false discovery rate.Gene-based association tests were performed using the versatile gene-based association study(VEGAS)method.RESULTS:In the codominant model,the ORs for SNPs rs2432143(1.517;95%CI:1.144-2.011)and rs2447867(1.258;95%CI:1.051-1.505)were statistically significant.In the dominant model,polymorphisms of rs1862610 and rs2447867 were found to be significant risk factors,with ORs of 1.337(95%CI:1.029-1.737)and 1.412(95%CI:1.061-1.881),respectively.In the recessive model,only the rs2432143 polymorphism was significant(OR=1.559,95%CI:1.150-2.114).The C-C type of ITGA1 haplotype block 2 was a significant protective factor against gastric cancer in the both codominant model(OR=0.602,95%CI:0.212-0.709,P=0.021)and the dominant model(OR=0.653,95%CI:0.483-0.884).The ITGA1 gene showed a significant gene-based association with gastric cancer in the VEGAS test.In the dominant model,the A-T type of ITGA1 haplotype block 2 was a significant risk factor(OR=1.341,95%CI:1.034-1.741).SNP rs2447867 might be related to the severity of gastric epithelial injury due to inflammation and,thus,to the risk of developing gastric cancer.CONCLUSION:ITGA1 gene SNPs rs1862610,rs2432143,and rs2447867 and the ITGA1 haplotype block that includes SNPs rs1862610 and rs2432143 were significantly associated with gastric cancer. | Dong-Hyuk Yim Yan-Wei Zhang Sang-Yong Eom Sun In Moon Hyo-Yung Yun Young-Jin Song Sei-Jin Youn Taisun Hyun Joo-Seung Park Byung Sik Kim Jong-Young Lee Yong-Dae Kim Heon Kim | 2013 | World Journal of Gastroenterology2013，19，35： | 6 |
| 2 | Risk of gastric cancer is associated with PRKAA1 gene polymorphisms in Koreans显示文摘AIM:To evaluate the association between genetic polymorphisms of the gene encoding AMP-activated protein kinase(PRKAA1)and the risk of gastric cancer.METHODS:The study subjects consisted of 477 ageand sex-matched case-control pairs.Genotyping was performed for 5 tag single nucleotide polymorphisms(SNPs):rs13361707,rs154268,rs3805486,rs6882903,and rs10074991.Associations between gastric cancer and putative risk factors(including the SNPs)were analyzed with multivariate conditional logistic regression models,after adjusting for potential confounding factors.Multiple testing corrections were implemented following methodology for controlling the false discovery rate.Gene-based association tests were performed by using the versatile gene-based association study(VEGAS)method.RESULTS:In the dominant model,SNPs rs13361707[odds ratio(OR)=1.51,95%CI:1.07-2.11)],rs154268(OR=1.65,95%CI:1.22-2.22),rs6882903(OR=1.48,95%CI:1.09-2.00),and rs10074991(OR=1.53,95%CI:1.09-2.16)were significantly associated with an increased risk of gastric cancer.In the recessive model,SNPs rs154268(OR=1.66,95%CI:1.22-2.26),rs3805486(OR=0.63,95%CI:0.46-0.85),and rs10074991(OR=1.47,95%CI:1.15-1.88)were significant risk or protective factors for gastric cancer.In the codominant model,the ORs of each of the5 SNPs were statistically significant.All SNPs in the model showed a dose-response relationship between the minor allele frequency and the risk of gastric cancer.Most notably,subjects with a homozygous minor allele in SNP rs10074991 showed 2.15 times the risk of gastric cancer as subjects without a minor allele.The PRKAA1 gene showed a significant gene-based association with gastric cancer in the VEGAS test.CONCLUSION:All 5 tested tag SNPs of the PRKAA1gene(rs13361707,rs154268,rs3805486,rs6882903,and rs10074991)were significantly associated with gastric cancer. | Yong-Dae Kim Dong-Hyuk Yim Sang-Yong Eom Sun In Moon Hyo-Yung Yun Young-Jin Song Sei-Jin Youn Taisun Hyun Joo-Seung Park Byung Sik Kim Jong-Young Lee Hee Kwan Won Heon Kim | 2014 | World Journal of Gastroenterology2014，20，26： | 3 |
| 3 | Dietary vitamin D intake and vitamin D related genetic polymorphisms are not associated with gastric cancer in a hospital-based case-control study in Korea显示文摘There have been few studies on the association between vitamin D levels and gastric cancer in Asian populations,but no studies have been performed on the interactions between vitamin D intake and polymorphisms in the vitamin D pathway.The effects of vitamin D intake,vitamin D related genetic polymorphisms,and their association with the incidence of gastric cancer were investigated in a hospital case-control study,including 715 pairs of newly diagnosed gastric cancer patients and controls matched for age and sex.Correlations between vitamin D intake and plasma vitamin D concentrations were also assessed in a subset of subjects.No statistically significant difference was observed in the dietary intake of vitamin D between the patients and controls,nor were there any evident associations between vitamin D intake and risk of gastric cancer in multivariate analyses.Vitamin D intake significantly correlated with the circulating 25-hydroxyvitamin D levels,but not with the active form of the vitamin,1,25-dihydroxyvitamin D.There were no statistically significant interactions between vitamin D intake,and VDR or TXNIP polymorphisms.This study suggests that dietary vitamin D intake is not associated with gastric cancer risk,and the genetic polymorphisms of vitamin D-related genes do not modulate the effect of vitamin D with respect to gastric carcinogenesis. | Sang-Yong Eom Dong-Hyuk Yim Dae-Hoon Kim Hyo-Yung Yun Young-Jin Song Sei-Jin Youn Taisun Hyun Joo-Seung Park Byung Sik Kim Yong-Dae Kim Heon Kim | 2018 | The Journal of Biomedical Research2018，32，4： | 2 |
