Analysis of sister-chromatid exchanges and tumorigenicity in cell hybrids.
The relationship between the 'spontaneous' frequency of sister-chromatid exchanges (SCE) and tumorigenicity was studied in a series of hybrids between a C57BL melanoma cell line and diploid cells, but no correlation was found between the 2 variables. Hybrids in which malignancy was suppressed and malignant segregants derived from them showed virtually identical SCE frequencies. Variation of SCE...
متن کاملSister chromatid exchanges, indices of human chromosome damage and repair: detection by fluorescence and induction by mitomycin C.
Sister chromatid exchanges in chromosomes from human lymphocytes grown two replication cycles in medium containing 5-bromodeoxyuridine can be detected by fluorescence microscopy after staining with the bisbenzimidazole dye 33258 Hoechst. These exchanges are much more frequent than chromosome or chromatid breaks and appear to be partly but not entirely due to 5-bromodeoxyuridine incorporation. S...
متن کاملSister chromatid exchanges in lymphocytes of humans anaesthetized with isoflurane.
The potential mutagenicity of isoflurane was investigated by the sister chromatid exchange (SCE) test using peripheral blood lymphocytes from patients before and after anaesthesia. Thirty patients, aged 18-59 yr (median 29.5 yr), were anaesthetized for minor orthopaedic operations with isoflurane and nitrous oxide in oxygen for 37-90 min (median 64 min). Venous blood samples were drawn before t...
متن کاملG2 chromosomal radiosensitivity and background frequency of sister chromatid exchanges of peripheral blood lymphocytes of breast cancer patients
Background: Chromosomal alterations play an important role in carcinogenesis. Enhanced chromosomal radiosensitivity is shown for many cancer predisposition conditions including breast cancer. In this study chromosomal radiosensitivity and the frequency of background sister chromnatid exchanges (SCE) in lymphocytes of normal individuals and breast cancer patients was compared. Materials...
متن کاملInduction of sister chromatid exchanges in human lymphocytes by DTPA.
The chelating agent, diethylenetriaminepentaacetic acid (DTPA) is a non-registered drug used in the treatment of over-exposure to heavy metals such as iron, zinc and lead (Fahey et al., 1961; Brugsch et al., 1965). DTPA has also been used on a few occasions in the United Kingdom when individuals have inhaled plutonium dust or received contaminated wounds (Schofield and Dolphin, 1974). These pat...
