Background: Inconsistencies have existed in research findings on the association between cardiovascular disease (CVD) and single nucleotide polymorphisms (SNPs) of ADIPOQ, triggering this up-to-date meta-analysis.

Methods: We searched for relevant studies in PubMed, EMBASE, Cochrane Library, CNKI, CBM, VIP, and WanFang databases up to 1st July 2017. We included 19,106 cases and 31,629 controls from 65 published articles in this meta-analysis. STATA 12.0 software was used for all statistical analyses.

Results: Our results showed that rs266729 polymorphism was associated with the increased risk of CVD in dominant model or in heterozygote model; rs2241766 polymorphism was associated with the increased risk of CVD in the genetic models (allelic, dominant, recessive, heterozygote, and homozygote). In subgroup analysis, significant associations were found in different subgroups with the three SNPs. Meta-regression and subgroup analysis showed that heterogeneity might be explained by other confounding factors. Sensitivity analysis revealed that the results of our meta-analysis were stable and robust. In addition, the results of trial sequential analysis showed that evidences of our results are sufficient to reach concrete conclusions.

Conclusions: In conclusion, our meta-analysis found significant increased CVD risk is associated with rs266729 and rs2241766, but not associated with rs1501299.

The Pacific oyster Crassostrea gigas is rich in taurine, a conditionally essential amino acid functioning in anti-oxidation, anti-inflammation, anti-aging, osmoregulation, and neuromodulation. Breeding oyster varieties with enhanced taurine content is significant to meet people's demand for high-quality oysters. In the present study, polymorphisms in the oyster cysteamine dioxygenase (CgADO) gene that encodes the central enzyme of the cysteamine pathway for taurine synthesis were investigated, and their association with taurine content was assessed in the Changhai (CH) and Qinhuangdao (QHD) populations.

Background: White matter hyperintensities (WMH) are commonly observed on MRI in Alzheimer's disease (AD), but the molecular pathways underlying their relationships with the ATN biomarkers remain unclear. The aim of this study was to identify genetic variants that may modify the relationship between WMH and the ATN biomarkers.

Method: This genome-wide interaction study (GWIS) included individuals with AD, MCI, and normal cognition from ADNI (n = 1012).

Genetics is the second strongest risk factor for Alzheimer's disease (AD) after age. More than 70 loci have been implicated in AD susceptibility so far, and the genetic architecture of AD entails both additive and nonadditive contributions from these loci. To better understand nonadditive impact of single-nucleotide polymorphisms (SNPs) on AD risk, we examined individual, joint, and interacting (SNPxSNP) effects of 139 and 66 SNPs mapped to the BIN1 and MS4A6A AD-associated loci, respectively.

Background: Whilst numerous studies have explored the relationship between Alzheimer's disease (AD) and diabetes, there remains significant conflicting evidence as to their relationship. Some studies suggest an increased likelihood of developing AD in individuals with diabetes, especially type 2 diabetes (T2D) and that both diseases share pathological features. In contrast, other studies indicate that T2D is more aligned with vascular cognitive impairment and dementia and associated cerebrovascular/white matter pathology.

Background: Single nucleotide polymorphism (SNP)-based genetic studies have identified many risk genes for Alzheimer's disease (AD), but only explain part of the heritability. Structural variation (SVs) may account for some of this otherwise unexplained heritability. In this study, we sequenced 1,519 AD patients and 2,010 controls using 30X whole-genome sequencing (WGS).
