Sulfotransferases (SULT) catalyse both the bioactivation and detoxification of a wide range of promutagens and carcinogens. The SULT1A1 gene possesses a G-->A polymorphism that results in a Arg to His substitution at codon 213, and the His allele has been shown to have a low activity and thermal stability. To test the hypothesis that individuals carrying(More)
To dissect the genetic architecture of blood pressure and assess effects on target organ damage, we analyzed 128,272 SNPs from targeted and genome-wide arrays in 201,529 individuals of European ancestry, and genotypes from an additional 140,886 individuals were used for validation. We identified 66 blood pressure-associated loci, of which 17 were new; 15(More)
Studies investigating the association between cytochrome P450 2E1 (CYP2E1) 5'-flanking region (PstI/RsaI) polymorphism and gastric cancer risk report conflicting results. The rationale for this meta-analysis was to determine whether CYP2E1*2 (c2) variant allele of CYP2E1 increases gastric cancer risk, especially by interacting with smoking, alcohol and(More)
Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the metabolism of folate, whose role in gastric carcinogenesis is controversial. The authors performed a meta-analysis and individual data pooled analysis of case-control studies that examined the association between C677T and A1298C polymorphisms (the former being associated with low folate(More)
OBJECTIVE Brain-derived neurotrophic factor (BDNF) is potentially involved in the pathogenesis of anxiety. We carried out meta-analyses to evaluate the relationship between the BDNF Val66Met (valine, methionine) polymorphism and anxiety disorders (AD) or anxiety-related personality traits (ARPT). METHODS Medline, Embase and PsycINFO were searched up to(More)
BACKGROUND A meta-analysis of published studies was performed in order to clarify the risk of gastric cancer associated with cigarette smoking status. METHODS Eligible studies were all the case-control studies investigating an association between smoking status and gastric cancer published from January 1, 1997, until June 30, 2006. In order to evaluate(More)
BACKGROUND Adiposity, as indicated by body mass index (BMI), has been associated with risk of cardiovascular diseases in epidemiological studies. We aimed to investigate if these associations are causal, using Mendelian randomization (MR) methods. METHODS The associations of BMI with cardiovascular outcomes [coronary heart disease (CHD), heart failure and(More)
BACKGROUND The understanding of non-genetic regulation of platelet indices--platelet count, plateletcrit, mean platelet volume, and platelet distribution width--is limited. The association of these platelet indices with a number of biochemical, environmental and clinical variables was studied in a large cohort of the general population. DESIGN AND METHODS(More)
Physical activity (PA) and micronutrients such as calcium (Ca), vitamin D (25OHD), and phosphate (PO) are important determinants of skeletal development. This case-control study examined the association of these nutritional biomarkers and different PA behaviours, such as habitual PA, weight-bearing exercise (WBE) and sedentary time (SED) with bone stiffness(More)
The distribution and the potential gene-gene and gene-environment interaction of selected metabolic genetic polymorphisms was investigated in relation to gastric cancer risk in an Italian population. One hundred and seven cases and 254 hospital controls, matched by age and gender, were genotyped for CYP1A1, CYP2E1, mEH, GSTM1, GSTT1, NAT2 and SULT1A1(More)
