Evaluation of links between high-density lipoprotein genetics, functionality, and aortic valve stenosis risk in humans.
Montréal, Canada. In Arterioscler Thromb Vasc Biol, 2014
APPROACH AND RESULTS: A total of 1435 single nucleotide polymorphisms in genes associated with HDL cholesterol levels (in or around GALNT2, LPL, ABCA1, APOA5, SCARB1, LIPC, CETP, LCAT, LIPG, APOC4, and PLTP) were genotyped in 382 patients with echocardiography-confirmed AVS (aortic jet velocity ≥2.5 m/s) and 401 controls.
A novel estrogen-regulated avian apolipoprotein.
London, United Kingdom. In Biochimie, 2013
In search for mammalian counterparts of Apo-IV, alignment of the sequence of the novel chicken protein with those of different mammalian apolipoproteins revealed stretches with limited similarity to regions of ApoC-IV and possibly with ApoE from various mammalian species.
Genetic loci associated with changes in lipid levels leading to constitution-based discrepancy in Koreans.
Taejŏn, South Korea. In Bmc Complement Altern Med, 2013
By analyzing TE and non-TE type (each 2,664 subjects) populations classified on the basis of Sasang constitutional medicine, we found that the minor allele effects of three variants enriched in TE type had a harmful influence on lipid risk (near apolipoprotein A-V (APOA5)-APOA4-APOC3-APOA1 on increased triglyceride: p = 8.90 × 10(-11), in APOE-APOC1-APOC4 on increased low-density lipoprotein cholesterol: p = 1.63 × 10(-5), and near endothelial lipase gene on decreased high-density lipoprotein cholesterol: p = 4.28 × 10(-3)), whereas those of three variants (near angiopoietin-like 3 gene, APOA5-APOA4-APOC3-APOA1, and near lipoprotein lipase gene on triglyceride and high-density lipoprotein cholesterol) associated in non-TE type had neutral influences because of a compensating effect.
Genetic variation in APOE cluster region and Alzheimer's disease risk.
Pamplona, Spain. In Neurobiol Aging, 2011
We report the fine mapping/sequencing results of promoter and regulatory regions of APOE cluster genes (APOE, APOC1, APOC4, APOC2, and TOMM40) in Alzheimer's disease (AD) risk as well as in the progression from mild cognitive impairment (MCI) to AD. Long-range sequencing in 29 MCI subjects who progressed to dementia revealed 7 novel variants.
Common genetic variation in multiple metabolic pathways influences susceptibility to low HDL-cholesterol and coronary heart disease.
Boston, United States. In J Lipid Res, 2010
After adjustment for multiple testing within each gene, single-nucleotide polymorphisms (SNP) significantly associated with case status were identified in the genes encoding LIPC (rs4775065, P < 0.0001); CETP (rs5882, P = 0.0002); RXRA (rs11185660, P = 0.0021); ABCA1 (rs2249891, P = 0.0126); ABCC6 (rs150468, P = 0.0206; rs212077, P = 0.0443); CUBN (rs7893395, P = 0.0246); APOA2 (rs3813627, P = 0.0324); SELP (rs732314, P = 0.0376); and APOC4 (rs10413089, P = 0.0425).
Identification of endogenous control genes for normalisation of real-time quantitative PCR data in colorectal cancer.
Galway, Ireland. In Bmc Mol Biol, 2009
RESULTS: The expression of thirteen candidate EC genes: B2M, HPRT, GAPDH, ACTB, PPIA, HCRT, SLC25A23, DTX3, APOC4, RTDR1, KRTAP12-3, CHRNB4 and MRPL19 were analysed in a cohort of 64 colorectal tumours and tumour associated normal specimens.
