Oxidized LDL (ox-LDL) is involved in the initiation and progression of atherosclerosis. Many factors can affect the LDL oxidation such as oxidative stress. The present study tested whether ox-LDL levels would be associated with apolipoprotein E (APOE), manganese superoxide dismutase (MnSOD) Ala16Val polymorphisms, and classic cardiovascular risk factors. ox-LDL levels were measured by thiobarbi...
This study evaluated the impact of 9 single nucleotide polymorphisms (SNPs) in 6 candidate genes (APOB, APOA5, APOE, APOC3, SCAP, and LDLR) over dyslipidemia in HIV-infected patients on stable antiretroviral therapy (ART) with undetectable viral loads. Blood samples were collected from 614 patients at reference services in the cities of Porto Alegre, Pelotas, and Rio Grande in Brazil. The SNPs ...
BACKGROUND The clinical phenotype of Pseudoxanthoma elasticum (PXE) affected patients, although progressive with age, is very heterogeneous, even in the presence of identical ABCC6 mutations, thus suggesting the occurrence of modifier genes. Beside typical skin manifestations, the cardiovascular (CV) system, and especially the peripheral vasculature, is frequently and prematurely compromised. ...
The aim of this study was to investigate whether single nucleotide polymorphisms (SNPs) in the regulatory regions of the apolipoprotein E (APOE) gene modify the well-established epsilon4-associated risk for Alzheimer's disease (AD). Sequencing of the APOE gene regulatory regions revealed four previously reported promoter SNPs and one novel SNP in the previously described macrophage enhancer (ME...
In the present study, we investigated age-related changes in interactions between efficiency of neuronal repair mechanisms and efficiency of cholinergic neurotransmission in the context of attentional orienting. In addition, we explored white matter volume changes as possible neuronal underpinnings. A sample of 230 healthy middle-aged (53-64 years) and older (65-75 years) adults was genotyped f...
BACKGROUND Recent data indicate that the rs1080985 single nucleotide polymorphism of the cytochrome P450 (CYP) 2D6 gene may affect the response to treatment with donepezil in patients with Alzheimer's disease. There is also evidence that the common apolipoprotein E (APOE) polymorphism may affect the response to treatment with donepezil in Alzheimer's disease. We investigated the association bet...
The present study aimed to investigate the correlation between apolipoprotein E (APOE) polymorphisms and the intracellular concentration of Ca2+ in astrocytes in the early stages after an injury. The chondroitin sulfate region of three APOE alleles (ε2, ε3 and ε4) was obtained by reverse transcription-polymerase chain reaction (RT-PCR). A recombinant plasmid, pEGFP-N1-APOE, was constructed and ...
Beta-amyloid 42 (Aβ42) concentrations in cerebrospinal fluid (CSF) are significantly decreased in Alzheimer's disease (AD). The aim of this study was to correlate genetic variability in presenilin 2 (PSEN2) in relation to Aβ42 concentrations and to confirm association of apolipoprotein E (APOE) alleles E4/E4 genotype with lower CSF Aβ42. Haplotype analysis of PSEN2 and APOE genotyping were perf...
A functional polymorphism of the brain-derivedneurotrophic factor (BDNF Val66Met) has been reported to affectmemory-related hippocampal activity. Apolipoprotein E (ApoE)gene polymorphism is known to be associated with Alzheimerdisease (AD), dementia with Lewy bodies (DLB), and Pick disease(PiD). We tested the hypothesis that BDNF Val and ApoE e4alleles confer susceptibil...
Alzheimer's disease and Down syndrome often exhibit close association and predictively share common genetic risk-factors. Presenilin-1 (PSEN-1) and Apolipoprotein E (APOE) genes are associated with early and late onset of Alzheimer's disease, respectively. Presenilin -1 is involved in faithful chromosomal segregation. A higher frequency of the APOE ε4 allele has been reported among young mother...
