This research aims to evaluate the effects of doxorubicin on mammary tumor cells derived from female rats and assess their response to treatment.
Mammary tumor cells from Sprague-Dawley rats were cultured as monolayers.
Dose-response curves were generated to assess the cytotoxic effects of doxorubicin.
[3H]thymidine labeling indices were used to evaluate DNA synthesis.
Median lethal dose for doxorubicin was found to be 10–4 M.
Treatment at doses between 10–4 to 10–5 M completely halted DNA synthesis of tumor cells.
Surviving cells displayed chromatin abnormalities and cytoplasmic changes.
