BACKGROUND Remarkable improvement in the life expectancy of the Indian population is expected to commensurate with the increase in number of dementia cases. Among various types of dementia, Alzheimer's disease (AD) and vascular dementia (VaD) are common and widely studied. We evaluated the role of apolipoprotein E (ApoE) and interleukin-6 (IL-6)-174 G/C gene polymorphism along with serum IL-6 l...

We evaluated genetic variants of apolipoprotein E (APOE HhaI) and their association with serum lipids in colorectal cancer (CRC), together with eating habits and personal history. Eight-seven adults with CRC and 73 controls were studied. APOE*2 (rs7412) and APOE*4 (rs429358) were identified by polymerase chain reaction-restriction fragment length polymorphism. APOE gene polymorphisms were simil...

Microtubule-associated protein tau (MAPT) and apolipoprotein E (APOE) are involved in the pathogenic mechanisms of Alzheimer's disease (AD). We prospectively followed three longitudinal independent samples (total n=319) with amnestic mild cognitive impairment (MCI) and analyzed whether MAPT H1/H2 haplotypes and APOE ε4 polymorphisms accelerated the rate of progression from MCI to dementia. At t...

Genetic variation in lipid regulatory genes, particularly APOE, significantly influences the risk of coronary artery disease (CAD). This study aimed to assess the association between APOE polymorphism and angiographically assessed coronary stenosis in Pakistani population. A total of 695 subjects (22.3% female, mean age = 54 ± 11 years) presenting with chest pain were enrolled after obtaining w...

Genotyping of single nucleotide polymorphisms (SNPs) in large populations presents a great challenge, especially if the SNPs are embedded in GC-rich regions, such as the codon 112 SNP in the human apolipoprotein E (apoE). In the present study, we have used immobilized locked nucleic acid (LNA) capture probes combined with LNA-enhancer oligonucleotides to obtain efficient and specific interrogat...

Background: Cardiovascular diseases constitute the main death cause worldwide resulting from a combination of genetic and lifestyle factors, and the prevalence among younger individuals has increased. It is important to early identify changes in lipid profile and the influence of genetic variations in specific genes on the individual patterns of lipid profile. Thus, the aim of this study was to...

Personalized medicine uses various individual characteristics to guide medical decisions. Apolipoprotein (ApoE), the most studied polymorphism in humans, has been associated with several diseases. The purpose of this review is to elucidate the potential role of ApoE polymorphisms in personalized medicine, with a specific focus on neurodegenerative diseases, by giving an overview of its influenc...

BACKGROUND Apolipoprotein E (APOE), which its ε4 allele has been reported as a risk factor in late onset Alzheimer's disease (AD), is the main cholesterol carrier in the brain. ATP-binding cassette transporter A1 (ABCA1) gene on chromosome 9, which has been known by genome-wide AD linkage study, has an important role in cellular cholesterol efflux. This study determines the association between ...

BACKGROUND The CYP19A1 enzyme (aromatase) encoded by the cytochrome P450 (CYP) 19A1 gene influences the final step in the biosynthesis of estrogen, which has been associated with Alzheimer disease (AD). It is possible that genetic polymorphisms in CYP19A1 could influence the risk of AD by altering the expression of CYP19A1. The ε4 allele of the apolipoprotein E (APOE) gene, which is the most si...

INTRODUCTION The study of variations in genes involved in the different events that trigger the atherogenic process, such as lipid metabolism (modification of LDL-cholesterol), endothelial function and hypertension, immune response (recruitment of macrophages and foam cell formation) and stability of atherosclerotic plaques (thrombosis), established the risk for suffering a vascular disorder. A...
