The major DNA adduct (greater than 95% total) resulting from the bioactivation of ethylene dibromide by conjugation with GSH is S-(2-(N7-guanyl)ethyl)GSH. The mutagenic potential of this adduct has been uncertain, however, because the observed mutagenicity might be caused by other adducts present at much lower levels, e.g. S-(2-N1-adenyl)ethyl)GSH.

The mutagenicity of the lipid peroxidation product, malondialdehyde (MDA), was measured in the lacZ alpha forward mutation assay using a recombinant M13 phage, M13MB102. Single-stranded M13MB102 DNA was reacted with MDA at neutral pH and the modified DNA was transformed into strains of Escherichia coli induced for the SOS response. Increasing concentrations(More)
The human mineralocorticoid receptor (MR) is a member of the steroid-thyroid hormone receptor superfamily, which includes receptors for retinoic acid, vitamin D, and other steroids, such as the glucocorticoids (which bind the glucocorticoid receptor, GR). MR and GR, the corticosteroid receptors, share significant homology and are activated by steroid(More)
Electrophoretic separation of oligonucleotides in denaturing polyacrylamide gels is primarily a function of length-dependent mobility. The 3' terminal nucleotide sequence of the oligonucleotide is a significant, secondary determinant of mobility and separation. Oligomers with 3'-ddT migrate more slowly than expected on the basis of length alone, and thus(More)
