The evaluation of the relationship between the dose to DNA of a genotoxic carcinogen and in vivo somatic cell mutagenesis may provide important information on the mechanisms leading to induced mutational events. The induction of DNA adducts and DNA m

Transgenic mice carrying bacteriophage lambda-based vectors harboring a lacZ or lacI reporter gene have been used in recent years for the detection, quantification, and characterization of spontaneous and induced gene mutations in vivo. The usefulnes

To study in vivo somatic mutations a C57BL/6 transgenic mouse model was constructed harboring multiple chromosomally integrated copies of the plasmid pUR288, which carried the lacZ reporter gene as the mutational target. We previously demonstrated th

Theories on the causes of aging, based on the accumulation of somatic mutations in tissues of an organism, were formulated decades ago, but remain insufficiently tested. Transgenic animals, equipped with integrated bacterial reporter genes that can b

An attempt was made to assign mouse lifespan-associated interstrain differences in DNA repair to a specific chromosomal region using a set of congenic mice. The sensitive 32P-postlabeling assay was employed to measure the removal of benzo[a]pyrene-in

DNA single-strand breaks (SSBs) and their disappearance during repair incubation were determined by alkaline filter elution in freshly isolated human peripheral blood lymphocytes (PBLs) after in vitro treatment with either the oxygen radical-generati

The induction and disappearance of DNA single-strand breaks (SSB) in human peripheral blood lymphocytes (PBL) and fibroblasts exposed to methyl methanesulfonate (MMS) were investigated by using the alkaline filter elution assay. In the two cell types

We investigated the induction and disappearance of DNA lesions that are detected as single-strand breaks (SSBs) with the alkaline filter elution technique, in human peripheral blood lymphocytes (PBLs) following exposure to N-ethyl-N-nitrosourea (ENU)

It has been hypothesized that Alzheimer's disease (AD) is caused by an accumulation of damage in DNA due to defective DNA-repair (21). Attempts to test this hypothesis by determining the activity of DNA-repair systems in nonneuronal cells from AD pat
