Anthracyclines are one of the most used drugs in the therapy of several malignant tumors. Unfortunately its use is still limited by their cardio-toxicity and by the presence of cancer cells resistant to these drugs. In the present study we evaluated the ability of a chemo-sensitizer agent, MPA (Medroxyprogesterone Acetate), to modify anthracyclines intranuclear uptake in normal leukocytes (NL) and in chronic lymphatic leukemia leukocytes (CLL). Moreover we evaluated the role of lipid peroxidation and nitric oxide (NO) production on antracyclines activity and on their combination with MPA. Our data show that MPA significantly increases anthracyclines uptake only in CLL cells and decreases anthracyclines induced lipid peroxidation.

Abstract
Anthracyclines are one of the most used drugs in the therapy of several malignant tumors. Unfortunately its use is still limited by their cardio-toxicity and by the presence of cancer cells resistant to these drugs. In the present study we evaluated the ability of a chemo-sensitizer agent, MPA (Medroxyprogesterone Acetate), to modify anthracyclines intranuclear uptake in normal leukocytes (NL) and in chronic lymphatic leukemia leukocytes (CLL). Moreover we evaluated the role of lipid peroxidation and nitric oxide (NO) production on antracyclines activity and on their combination with MPA. Our data show that MPA significantly increases anthracyclines uptake only in CLL cells and decreases anthracyclines induced lipid peroxidation.
