Integrity Of Dna

1. The integrity of DNA extracted from Escherichia coli strain 15T(-) after thymine-less death was examined by studying the effects of treatment with aqueous alkali on the solubility in dilute acids and by viscosity and ultracentrifugal measurements, some of which were designed to detect single-strand breaks or inter-strand cross-links. None of the results showed that there was any modification or damage associated with thymine-less death.

✓ The photo- and radiosensitizing properties of bromodeoxyuridine (BUdR) were assessed in vitro using the 9L rat brain tumor cell line. Pretreatment of 9L cells with 10 µM BUdR for 24 hours followed by irradiation with ultraviolet (UV) light resulted in a dose-enhancement ratio of 3.8:1 compared with UV radiation alone. X-radiation of BUdR-pretreated cells produced a dose-enhancement ratio of 1.7:1. Alkaline elution analysis of deoxyribonucleic acid (DNA) from cells treated with BUdR and UV irradiation showed the presence of DNA single-strand breaks and DNA-protein cross-links. Analysis of DNA from cells treated with BUdR and then x-irradiated showed no increase in DNA single-strand breaks compared with cells treated with x-radiation alone; no DNA-protein cross-links could be detected. The possible clinical relevance of these findings is discussed.
