We have used restriction isotyping (restriction enzyme isoform genotyping) for rapid typing of common apolipoprotein E isoforms (E2, E3, E4). ApoE restriction isotyping used oligonucleotides to amplify apolipoprotein E gene sequences containing amino acid positions 112 and 158. The amplification products were digested with HhaI and subjected to(More)
BACKGROUND The familial aggregation of coronary heart disease can be in large part accounted for by a clustering of cardiovascular disease risk factors. To elucidate the determinants of cardiovascular disease, many epidemiological studies have focused on the behavioral and lifestyle determinants of these risk factors, whereas others have examined whether(More)
Accurately determining the distribution of rare variants is an important goal of human genetics, but resequencing of a sample large enough for this purpose has been unfeasible until now. Here, we applied Sanger sequencing of genomic PCR amplicons to resequence the diabetes-associated genes KCNJ11 and HHEX in 13,715 people (10,422 European Americans and(More)
We conducted a meta-analysis of genome-wide association studies of systolic (SBP) and diastolic (DBP) blood pressure in 19,608 subjects of east Asian ancestry from the AGEN-BP consortium followed up with de novo genotyping (n = 10,518) and further replication (n = 20,247) in east Asian samples. We identified genome-wide significant (P < 5 × 10(-8))(More)
The mitochondrial DNA (mtDNA) control regions for common chimpanzee, pygmy chimpanzee and gorilla were sequenced and the lengths and termini of their D-loop DNA's characterized. In these and all other species for which there are data, 5' termini map to sequences that contain the trinucleotide YAY. 3' termini are 25-51 nucleotides downstream from a sequence(More)
Restriction endonuclease fragments produced by EcoRI/AvaI or KpnI digestion and containing the small (12S) ribosomal RNA (rRNA) genes from the mitochondrial DNAs (mtDNAs) of the common chimpanzee, pygmy chimpanzee, gorilla, and orangutan were inserted into the plasmids pBR322 or pADD1. After species verification the inserted fragments were digested with(More)
Mammalian mitochondrial DNAs contain a conserved origin of light-strand replication that supports accurate initiation of DNA synthesis in vitro. This provides an opportunity to examine the sequence requirements for initiation through in vitro analysis of a series of deleted and mutagenized DNA templates. These assays use enzymes isolated from human(More)
Obesity is a major predisposing factor for the development of several chronic diseases including non-insulin dependent diabetes mellitus (NIDDM) and coronary heart disease (CHD). Leptin is a serum protein which is secreted by adipocytes and thought to play a role in the regulation of body fat. Leptin levels in humans have been found to be highly correlated(More)
BACKGROUND Since insulin resistance is thought to be the underlying mechanism for metabolic syndrome, affected individuals might be sensitive to a dietary sodium intervention. We aimed to examine the association between metabolic syndrome and salt sensitivity of blood pressure. METHODS 1906 Chinese participants without diabetes, aged 16 years or more,(More)
