Genome-wide association studies have identified variants associated with BMI in populations of European descent. We sought to establish whether genetic variants that are robustly associated with BMI could modulate anthropometric traits and the obesity risk in an Algerian population sample, the ISOR study. The ISOR study of 787 adult subjects (aged between(More)
To more rapidly identify candidate genes located within chromosomal regions of interest defined by genome scan studies in Alzheimer's disease (AD), we have developed a customized microarray containing all the ORFs (n=2741) located within nine of these regions. Levels of gene expression were assessed in total RNA from brain tissue of 12 controls and 12 AD(More)
Neurofibrillary tangles and senile plaques, constituted of extracellular amyloid deposits (Abeta), are the two defining pathological hallmarks of Alzheimer's disease (AD). Inhibiting the synthesis or aggregation of Abeta or increasing its clearance may reduce the detrimental effects of this peptide and consequently improve cognitive functions in patients.(More)
Cerebral accumulation of beta-amyloid peptide (Abeta) is a central event in the pathogenesis of Alzheimer's disease (AD). Several proteases were shown to hydrolyze Abeta in vitro or in cell-based assays, and are likely candidates for a role in Abeta clearance in brain. Previous reports suggest that matrix metalloproteinases (MMPs) could be involved in such(More)
The importance of apolipoprotein E (APOE) in lipid and lipoprotein metabolism is well established. However, the impact of APOE polymorphisms has never been investigated in an Algerian population. This study assessed, for the fist time, the relationships between three APOE polymorphisms (epsilon, rs439401, rs4420638) and plasma lipid concentrations in a(More)
Genome-wide association studies have shown that the rs340874 single nucleotide polymorphism (SNP) in PROX1 is a genetic susceptibility factor for type 2 diabetes. We conducted genetic and molecular studies to better understand the role of PROX1 in type 2 diabetes. We assessed the impact of the whole common genetic variability of PROX1 (80 SNPs) on type 2(More)
BACKGROUND The DD genotype for the angiotensin-I converting enzyme (ACE I) deletion allele (D) polymorphism is a possible genetic risk factor for restenosis after coronary stent implantation. We aimed to establish whether or not blockade of ACE with high doses of ACE inhibitors could reduce this risk of angiographic restenosis. METHODS We characterised(More)
Background: Conflicting results have been reported regarding the association of gene polymorphisms in the renin-angiotensin system (RAS) with different aspects of coronary artery disease (CAD), such as myocardial infarction, neointimal hyperplasia or coronary artery vasomotion. Since previous studies have linked angiotensin II to aneurysmal disease, our(More)
The transcription factor 7-like 2 (TCF7L2) gene is the most significant genetic risk factor for type 2 diabetes (T2D). Association analyses were performed on participants (n = 751, aged between 30 and 64) in the ISOR population-based study in the city of Oran. Dietary intakes were estimated using a weekly food frequency questionnaire. The T allele of the(More)
