BACKGROUND: Cholesteryl ester transfer protein (CETP) is involved in diabetic dyslipidemia. OBJECTIVE: We aim to test the hypothesis that CETP might be of importance in mediating dyslipidemia-related susceptibility to cognitive deficits in diabetic patients. METHODS: We recruited 190 type 2 diabetic patients and divided them into two groups according to the Montreal Cognitive Assessment (MoCA) score. The association between CETP and cognitive decline was analyzed with logistic regression and stratification...

In this study we explored the association between aging-related phenotypes previously reported to predict survival in old age and variation in 77 genes from the DNA repair pathway, 32 genes from the growth hormone 1/ insulin-like growth factor 1/insulin (GH/IGF-1/INS) signalling pathway and 16 additional genes repeatedly considered as candidates for human longevity: APOE, APOA4, APOC3, ACE, CETP, HFE, IL6, IL6R, MTHFR, TGFB1, SIRTs 1, 3, 6; and HSPAs 1A, 1L, 14. Altogether, 1,049 single nucleotide polymorphisms (SNPs) were genotyped in 1,088 oldest-old (age 92-93 years) Danes and analysed with phenotype data on physical functioning (hand grip strength), cognitive functioning (mini mental state examination and a cognitive composite score), activity of daily living and self-rated health...

The aims of this study were to investigate risk factors for cognitive and functional decline among 193 patients with Alzheimer's disease dementia (AD), and to conduct pharmacogenetic analysis on cerebrovascular metabolism modulators, taking into account APOE haplotypes and the genotypes of ACE, CETP, LDLR and the LXR-β gene. For all patients, later age at AD onset was the most important risk factor for faster cognitive and functional decline, while the late-life coronary heart disease risk was inversely related to cognitive decline only for carriers of APOE4+ haplotypes...

Cholesterol has been implicated in the pathogenesis of late-onset Alzheimer's disease (LOAD) and the cholesteryl ester transfer protein (CETP) is critical to cholesterol regulation within the cell, making CETP an Alzheimer's disease candidate gene. Several studies have suggested that CETP I405V (rs5882) is associated with cognitive function and LOAD risk, but findings vary and most studies have been conducted using relatively small numbers of samples. To test whether this variant is involved in cognitive function and LOAD progression, we genotyped 4486 subjects with up to 12 years of longitudinal cognitive assessment...

OBJECTIVES: Accumulating evidence suggested that dysregulation of cholesterol homeostasis might be a major etiologic factor in initiating and promoting neurodegeneration in Alzheimer's disease (AD). ATP-binding cassette transporter A1 (ABCA1), hepatic lipase (HL, coding genes named LIPC) and cholesteryl ester transfer protein (CETP) are important components of high-density lipoprotein (HDL) metabolism and reverse cholesterol transport (RCT) implicated in atherosclerosis and neurodegenerative diseases...

Common polymorphisms of the Cholestryl Ester Transfer Protein (CETP) gene may predict lower risk of cognitive decline. We investigated the association of cognitive function with CETP genotype in a population-based cohort of 4135 persons aged 35-82 years. Cognitive function was measured with the Ruff Figural Fluency Test (RFFT; worst score, 0 points; best score, 175 points) and CETP I405V and Taq1B genotypes were determined by polymerase chain reaction. RFFT score was not associated with I405V genotype in persons aged 35-64 years...

The cholesteryl ester transfer protein (CETP) gene plays an essential role in regulating cholesterol homeostasis and is a candidate susceptibility gene for late-onset Alzheimer's disease (AD). Recent finding suggests that the CETP I405V polymorphism (rs5882) is associated with a slower rate of memory decline and a lower risk of incident dementia. Using data from two ongoing epidemiologic clinical-pathologic cohort studies of aging and dementia in the United States, the Religious Order Study and the Memory and Aging Project, we evaluated the association of the CETP I405V polymorphism (rs5882) with cognitive decline and risk of incident AD in more than 1300 participants of European ancestry...

Two alleles in cholesteryl ester transfer protein (CETP) gene polymorphisms have been disputably linked to enhanced cognition and decreased risk of Alzheimer's disease (AD): the V and A alleles of I405V and C-629A. This study investigates whether these polymorphisms affect brain structure in 188 elderly controls and 318 AD or mild cognitive impairment (MCI) subjects from the Alzheimer's Disease Neuroimaging Initiative cohort. Nominally signficant associations were dependent on APOE ε4 carrier status. In APOE ε4 carriers, the V and A alleles, both of which decrease CETP and increase HDL, associated with greater baseline cortical thickness and less 12-month atrophy in the medial temporal lobe...

The gene encoding the cholesteryl ester transfer protein (CETP) plays an integral role in lipid metabolism. We evaluated common genetic variation spanning CETP for association with cognitive decline as well as incident and prevalent dementia and Alzheimer disease risk. Data from four population-based twin studies and a case-control sample were included, encompassing an analysis sample of 1513 dementia cases and 2137 controls with available CETP genotypes and covariates. Memory and perceptual speed performance was assessed over 16 years in up to 1540 participants...

INTRODUCTION: Currently there are notable differences in the aging of individuals in modern populations. While some of them enjoy a long healthy aging, others develop neurodegenerative diseases, such as Alzheimer's disease (AD). Environmental factors are critical, but genetics could explain the differences observed. It has recently been postulated that longevity genes might also be neuroprotective. OBJECTIVES: To assess whether certain genetic variants associated with longevity might have a neuroprotective effect...

CONTEXT: Polymorphisms in the cholesteryl ester transfer protein (CETP) gene have been associated with exceptional longevity and lower cardiovascular risk, but associations with memory decline and dementia risk are unclear. OBJECTIVE: To test the hypothesis that a single-nucleotide polymorphism (SNP) at CETP codon 405 (isoleucine to valine V405; SNP rs5882) is associated with a lower rate of memory decline and lower risk of incident dementia, including Alzheimer disease (AD)...

Cholesteryl ester transfer protein (CETP), a component of the high density lipoprotein (HDL), plays a central role in reverse cholesterol transport. We investigated the association of two putative functional CETP polymorphisms (C-629A and I405V) with the risk of vascular dementia (VD) and tested if this association is influenced by the presence of APOE4 allele. Our study included 163 VD patients (mean age: 74.25 +/- 7.9 years) and 452 cognitively healthy probands (mean age: 70.81 +/- 7.9 years). As a biological correlate, the association of CETP gene variants with white matter lesion (WML) load was investigated...

BACKGROUND: High-density lipoprotein cholesterol (HDL-C) and cholesteryl ester transfer protein (CETP) gene deficiency mutations that increase HDL-C levels have been associated with exceptional longevity. However, a recent clinical trial of a promising CETP inhibitor that markedly increases HDL-C was terminated due to increased mortality. In light of this controversy, we examined the relationship among HDL-C, CETP mutations, and longevity phenotypes in the long-lived Japanese-American men of the Honolulu Heart Program (HHP)...

An unrealized potential to understand the genetic basis of aging in humans, is to consider the immense survival advantage of the rare individuals who live 100 years or more. The Longevity Gene Study was initiated in 1998 at the Albert Einstein College of Medicine to investigate longevity genes in a selected population: the "oldest old" Ashkenazi Jews, 95 years of age and older, and their children. The study proved the principle that some of these subjects are endowed with longevity-promoting genotypes. Here we reason that some of the favorable genotypes act as mechanisms that buffer the deleterious effect of age-related disease genes...

A cholesteryl ester transfer protein (CETP) genotype (V/V homozygosity for I405V, NCBI dbSNP rs5882) has been associated with preservation of cognitive function in old age, in addition to its associations with exceptional longevity and cardiovascular disease. We tested the hypotheses that this polymorphism was associated with either level of cognitive function or lifetime cognitive change in 525 participants who took part in the Scottish Mental Survey of 1932. Participants took the same well-validated mental ability test at ages 11 and 79...

OBJECTIVE: To test whether cholesterol ester transfer protein (CETP) genotype (VV homozygosity for I405V) is associated with preservation of cognitive function in addition to its association with exceptional longevity. METHODS: We studied Ashkenazi Jews with exceptional longevity (n = 158; age 99.2 +/- 0.3 years) for the associations of CETP VV genotype and lipoprotein phenotype, using the Mini-Mental State Examination (MMSE). To confirm the role of CETP in a younger cohort, we studied subjects from the Einstein Aging Study (EAS) for associations between CETP VV and cognitive impairment...

Subjects with exceptional longevity have a lower incidence and/or significant delay in the onset of age-related disease, and their family members may inherit biological factors that modulate aging processes and disease susceptibility. In a case control study, we aim to determine phenotype and genotype of exceptional longevity in a genetically homogenous population (Ashkenazi Jews), and their offspring, while an age-matched control group of Ashkenazi Jews was used as control groups. We demonstrated that exceptional longevity and healthy aging in humans is an inherited phenotype across three generations...

Epidemiological studies have enhanced the importance of high-density lipoprotein (HDL) as a risk factor for CAD, as well as disability and frailty in the oldest elderly. Therefore, HDL and molecules involved in HDL metabolism seem to be attractive candidates for longevity-promoting factors. A series of observational studies has demonstrated that the predominance of the larger, more lipid-rich HDL2 subclass is a reproducible phenotype among centenarians. This finding was recently evolved by nuclear magnetic resonance technology in quantification of lipoprotein particle size...

The ocuolocerebrorenal syndrome of Lowe (OCRL) is an X-linked recessive disorder which is characterized by renal tubular dysfunction, congenital cataracts, and cognitive impairment. In a review article by Charnas et al. (N Engl J Med 1991; 324: 1318-25), hypercholesterolemia, due to elevated high-density lipoprotein cholesterol (HDL-C) levels, was described as being highly prevalent in OCRL patients. This report prompted us to examine three OCRL children in two unrelated families and we confirmed the high prevalence of high serum HDL-C levels in the patients (3/3)...
