英文摘要
There are two primary objectives for the glycophorin A-based somatic
mutation analysis project. The first objective is to determine the
magnitude and types of somatic mutational damage in liquidators exposed
to radiation from the Chernobyl nuclear power accident as measured by the
glycophorin A (GPA) assay. Analysis will be performed on blood samples
from Russian liquidators with low-dose exposures and Russian controls,
and will include measurements of the frequency of both hemizygous NO and
homozygous NN variant erythrocytes. Measurements of the frequencies of
somatic cell mutations at the GPA locus will be correlated with different
indicators of genetic damage from other projects in the program project
to provide a comprehensive analysis of genetic damage and potential
health consequences in the liquidator population.
The second objective is to utilize GPA data from the Chernobyl liquidator
population to determine optimal strategies for detecting low-dose
radiation exposures that may be applicable for future studies in other
populations. Personal history data from questionnaires will be utilized
to identify factors that contribute to inter-individual variability.
Statistical procedures will be identified to adjust for confounding
factors and facilitate differentiation between exposed and control
populations. Results from the GPA assay will be compared with the
results from other biodosimeters in the program project to determine the
relative sensitivity and reliability of the different methods, and the
power of the combined data for detecting low-dose radiation exposure in
humans.
