Effects of temperature on sister chromatid exchanges
Abstract
The influence of temperature on sister chromatid exchanges was investigated, and the results are discussed in connection with factors possible involved in temperature-induced SCE-formation. Whereas the SCE frequency increased with increasing growth temperature in a cell line of Xenopus laevis (EAX), which permits the examination of great temperature differences, a Chinese hamster cell line (V-79) revealed a U-shaped temperature-response curve. In addition, it was found that cold treatment at 4 degrees C caused an induction of SCEs in the V-79 cell line. Different BrdU concentrations had no effect on the temperature-induced SCE frequencies and mitomycin C led to an induction of SCEs parallel to the base-line values at different temperatures.
