OBJECTIVE To study correlation between the Xba I polymorphism of apoB gene and plasma lipid profiles in Li ethnic group. METHODS Total 151 cases of healthy Li people were recruited randomly by cluster sampling and 200 Han people were recruited as control; blood was drawn to analyze Xba I polymorphism distribution of apoB gene and serum lipid levels.

1. CYP2C19 is a polymorphism of cytochrome P450, which is responsible for the metabolism of many drugs. The genetic polymorphism shows interethnic variation and it has been demonstrated that the frequency of poor metabolizers (PM) and the distribution of alleles of CYP2C19 vary among Chinese ethnic nationalities. The aim of the present study was to(More)
The 4-bp deletion (-CTTT) at codon 41/42 (CD41/42) of the human β-globin gene represents one of the most common β-thalassemia mutations in East Asia and Southeast Asia, which is historically afflicted with endemic malaria, thus hypothetically evolving under natural selection by malaria infection. To understand the evolutionary process of generating the(More)
Reduced mitochondrial function is an important cause of aging and age-related diseases. We previously revealed a relatively higher level of mitochondrial DNA (mtDNA) content in centenarians. However, it is still unknown whether such an mtDNA content pattern of centenarians could be passed on to their offspring and how it was regulated. To address these(More)
Apolipoprotein E (APOE), translocase of outer mitochondrial membrane 40 homolog (TOMM40) and apolipoprotein C-I (APOC1) may extend lifespan by marked delay or escape from age-related diseases. This study aimed to elucidate the association of human longevity with genetic variations in TOMM40/APOE/APOC1 region in a Chinese population. Ten tag(More)
The silent information regulator SIR2/SIRT1gene has been demonstrated as regulating lifespan in many model organisms, including yeast, worms, fruit flies and rodents. SIRT1, the human homolog of SIR2, is considered a candidate gene as a modifier of human life expectancy. In the current study we included 616 long-lived individuals and 846 matched younger(More)
OBJECTIVE To investigate the allelic frequencies of polymorphisms of alpha Taq I and beta Bcl I, Hinf I A/C, 448 G/A, beta BsmA I G/C, +1689T/G, -148C/T, -249C/T, -455G/A in Hainan Han population and their association with plasma fibrinogen level. METHODS Turbidmetric assay was used to measure plasma fibrinogen level of two hundred and thirty-eight(More)
In an effort to investigate the subtelomeric region of the X chromosome among Orientals, five DNA sites in the F8C and G6PD genes were analyzed in a sample of 46 chromosomes belonging to the Chinese Li population, an ethnic group characterized by a high prevalence of G6PD deficiency. The DNA sites analyzed, which are highly polymorphic in other populations,(More)
OBJECTIVE To analyze the frequency of FGB gene -1420G/A, -993C/T and -854G/A polymorphisms, and their association with plasma fibrinogen levels in patients with coronary heart disease and in health adults. METHODS The FGB gene -1420G/A, -993C/T and -854G/A polymorphisms were analyzed with restriction fragment length polymorphisms, polymerase chain(More)
The E2F1 transcription factor is a well known regulator of cell proliferation and apoptosis, but its role in response to DNA damage is less clear. 8-Chloro-adenosine (8-Cl-Ado), a nucleoside analog, can inhibit proliferation in a variety of human tumor cells. However, it is still elusive how the agent acts on tumors. Here we show that A549 and H1299 cells(More)
