An approach to incorporate linkage disequilibrium structure into genomic association analysis

引用

Journal of Genetics and Genomics 2008年第6期35卷 381-385页

作者： Diane Wagener statistics and epidemiology Unit Research Triangle Institute

In this study, we propose to use the principal component analysis （PCA） and regression model to incorporate linkage disequilibrium （LD） in genomic association data analysis. To accommodate LD in genomic data and reduce multiple testing, we suggest performing PCA and extracting the PCA score to capture the variation of genomic data, after which regression analysis is used to assess the association of the disease with the principal component score. An empirical analysis result shows that both genotype-based correlation matrix and haplotype-based LD matrix can produce similar results for PCA. Principal component score seems to be more powerful in detecting genetic association because the principal component score is quantitatively measured and may be able to capture the effect of multiple loci.

Association of cholesterol with risk of pancreatic cancer:A meta-analysis

引用

World Journal of Gastroenterology 2015年第12期21卷 3711-3719页

作者： Jia Wang Wei-Jing Wang Long Zhai Dong-Feng Zhang department of epidemiology and Health statistics Qingdao University Medical College

AIM: To evaluate the effect of dietary cholesterol and serum total cholesterol(TC) on the risk of pancreatic cancer. METHODS: A literature search was performed up to June 2014 in Pub Med, EMBASE, China National Knowledge Infrastructure and China Biology Medicalliterature database for relevant articles published in English or Chinese. Pooled relative risks(RRs) with 95% confidence intervals(CIs) were calculated with a random-effects model. RESULTS: We included 14 published articles with 439355 participants for dietary cholesterol, and 6 published articles with 1805697 participants for serum TC. For the highest vs lowest category of dietary cholesterol, the pooled RR(95%CI) of pancreatic cancer was 1.308(1.097-1.559). After excluding two studies(RR > 3.0), the pooled RR(95%CI) was 1.204(1.050-1.380). In subgroup analysis stratified by study design, the pooled RRs(95%CIs) were 1.523(1.226-1.893) for case-control studies and 1.023(0.871-1.200) for cohort studies. The association of dietary cholesterol with the risk of pancreatic cancer was significant for studies conducted in North America [1.275(1.058-1.537)] and others [2.495(1.565-3.977)], but not in Europe [1.149(0.863-1.531)]. No significant association [1.003(0.859-1.171)] was found between the risk of pancreatic cancer and serum TC. CONCLUSION: Dietary cholesterol may be associated with an increased risk of pancreatic cancer in worldwide populations, except for Europeans. The results need to be confirmed further.

XPC Polymorphism Increases Risk of Digestive System Cancers:Current Evidence from A Meta-Analysis

引用

Chinese Journal of Cancer Research 2012年第3期24卷 181-189页

作者： Xia Jiang Li-tao Zhou Shan-chun Zhang Kun Chen department of epidemiology and Health statistics Zhejiang University School of MedicineHangzhou 310058China

Objective： Xeroderma pigmentosum complementation group C （XPC） participates in the initial recognition of DNA damage during nucleotide excision repair process in global genomic repair. Our meta-analysis was performed to evaluate the association between three polymorphisms （Lys939Gln, PAT＋/- and Ala499Val） of XPC gene and risk of digestive system cancers. Methods： All the relevant case-control studies published to April 2011 were identified through searching PubMed. Digestive system cancer risk with the three polymorphisms was estimated for each study by odds ratio （OR） with its 95% confidence interval （95% CI）. Results： We found an increased overall risk for digestive system cancers in all three models of Lys939Gln AC （AC/CC vs. AA： OR, 1.20; 95% CI, 1.11-1.30; CC vs. AC/AA： OR, 1.24; 95% CI, 1.11-1.39; CC vs. AA： OR, 1.36; 95% CI, 1.21-1.53）. When strati？ed by ethnicity, results remained significant in Asian population （AC/CC vs. AA： OR, 1.18; 95% CI, 1.02-1.37; CC vs. AC/AA： OR, 1.32; 95% CI, 1.1-1.51; CC vs. AA： OR, 1.35; 95% CI, 1.08-1.70）, but not for Caucasians. However for Ala499Val CT, a significant protective effect of T allele was only observed in the dominant model. Otherwise, no significant results were observed for PAT＋/-. Conclusion： XPC Lys939Gln AC polymorphism may play an important role in digestive system cancer susceptibility.

BACKGROUND Adiponectin(ADIPOQ) is an important factor involved in the regulation of both carbohydrate and lipid metabolism. Polymorphisms in the ADIPOQ gene are known to influence an individual's predisposition to metabolic syndrome and type 2 diabetes. Moreover, women with gestational diabetes mellitus(GDM) are at an increased risk of developing type 2 diabetes. Several studies have been conducted previously to assess the association between ADIPOQ polymorphisms and GDM; however, the results of the association are *** To quantitatively evaluate the association between ADIPOQ +45 T/G, +276 G/T,and-11377 C/G polymorphisms and the risk of *** A systematic search of EMBASE, PubMed, CNKI, Web of Science, and WANFANG DATA was conducted up to October 20, 2018. We calculated merged odds ratios(ORs) with 95% confidence intervals(CIs) using a fixed-effects or random-effects model depending on the between-study heterogeneity to evaluate the association between AIDPOQ +45 T/G, +276 G/T, and-11377 C/G polymorphisms and the risk of GDM. Subgroup analysis was performed by ethnicity. Publication and sensitivity bias analyses were performed to test the robustness of the association. All statistical analyses were conducted using Stata *** Nine studies of +45 T/G included 1024 GDM cases and 1059 controls, five studies of +276 G/T included 590 GDM cases and 595 controls, and five studies of-11377 C/G included 722 GDM cases and 791 controls. Pooled ORs indicated that+45 T/G increased GDM risk in Asians(allelic model: OR = 1.47, 95%CI: 1.27-1.70,P = 0.000; dominant model: OR = 1.54, 95%CI: 1.27-1.85, P = 0.000; recessive model: OR=2.00, 95%CI: 1.43-2.85, P = 0.000), not in South Americans(allelic model: OR = 1.21, 95%CI: 0.68-2.41, P = 0.510; dominant model: OR = 1.13, 95%CI:,0.59-2.15, P = 0.710; recessive model: OR = 2.18, 95%CI: 0.43-11.07, P = 0.350).There were no significant associations between +276 G/T(allelic model: OR = 0.88,95%CI: 0.74-1.05, P = 0

作者： Shi-Min Hu Meng-Shi Chen Hong-Zhuan Tan department of epidemiology and Health statistics Xiangya School of Public Health Central South University

BACKGROUND Resistin is most likely involved in the pathogenesis of gestational diabetes mellitus(GDM), but the existing findings are *** To review the literature investigating the associations of the risk of GDM with serum level of *** A systematic literature search was performed using MEDLINE, EMBASE, and Web of Science(all databases). This meta-analysis included eligible studies that:(1) investigated the relationship between the risk of GDM and serum resistin;(2)included GDM cases and controls without GDM;(3) diagnosed GDM according to the oral glucose-tolerance test;(4) were performed in humans;(5) were published as full text articles in English; and(6) provided data with median and quartile range, median and minimum and maximum values, or mean and standard deviation. The pooled standardized mean difference(SMD) and 95%confidence interval(CI) were calculated to estimate the association between the risk of GDM and serum resistin. To analyze the potential influences of need for insulin in GDM patients and gestational age at blood sampling, we performed a subgroup analysis. Meta-regression with restricted maximum likelihood estimation was performed to assess the potentially important covariate exerting substantial impact on between-study *** The meta-analysis for the association between serum resistin level and GDM risk included 18 studies(22 comparisons) with 1041 cases and 1292 controls. The total results showed that the risk of GDM was associated with higher serum resistin level(SMD = 0.250, 95%CI: 0.116, 0.384). The "after 28 wk" subgroup, "no need for insulin" subgroup, and "need for insulin" subgroup indicated that higher serum resistin level was related to GDM risk("after 28 wk" subgroup: SMD =0.394, 95%CI: 0.108, 0.680; "no need for insulin" subgroup: SMD = 0.177, 95%CI:0.018, 0.336; "need for insulin" subgroup: SMD = 0.403, 95%CI: 0.119, 0.687).

作者： Weidong Liu Dennis Leung Qi-Man Shao School of Mathematical Sciences Shanghai Jiao Tong University School of Mathematics and statistics University of Melbourne department of statistics and Data Science SICMSouthern University of Science and Technology

In a one-way analysis-of-variance(ANOVA) model,the number of pairwise comparisons can become large even with a moderate number of *** by this,we consider a regime with a growing number of groups and prove that,when testing pairwise comparisons,the Benjamini-Hochberg(BH) procedure can asymptotically control false discoveries,despite the fact that the involved t-statistics do not exhibit the wellknown positive dependence structure required for exact false discovery rate(FDR) *** Tukey's perspective that the difference between the means of any two groups cannot be exactly zero,our main result provides control over the directional false discovery rate and directional false discovery proportion.A key technical contribution of our work is demonstrating that the dependence among the t-statistics is sufficiently weak to establish the convergence result typically required for asymptotic FDR *** analysis does not rely on conventional assumptions such as normality,variance homogeneity,or a balanced design,thereby offering a theoretical foundation for applications in more general settings.
