Morphological and biochemical changes in human fibroblast lines induced by anthracyclines during apoptosis.

We show that treating human trisomic fibroblasts with anthracyclines - aclarubicin, daunorubicin and idarubicin - leads to certain changes in these cells; namely the activation of caspase 3, morphological changes and an increase in the level of intracellular calcium. These results suggest that anthracycline drugs are also able to induce apoptosis in pathological, trisomic cells.
