The relationship between membrane permeability to adriamycin and adriamycin cytotoxicity in CHO cells at elevated temperatures. 1987

The cytotoxicity of adriamycin at elevated temperatures was studied in CHO cells in vitro using a clonogenic assay. There is a significant increase in the cytotoxicity of adriamycin at temperatures which are not lethal to mammalian cells (38 degrees C-42 degrees C). The uptake of [14C]adriamycin was studied in similar conditions to determine whether the thermal enhancement of adriamycin cytotoxicity was due to an increase in membrane permeability. Although measurable increases in adriamycin uptake occur in the elevated but non-lethal temperature range, they are insufficient to explain the observed increase in cytotoxicity.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
