Induction of DNA damage, inhibition of DNA synthesis and suppression of c-myc expression by the anthracycline analog, idarubicin (4-demethoxy-daunorubicin) in the MCF-7 breast tumor cell line

Studies were designed to elucidate the basis for the antiproliferative activity of the anthracycline antibiotic, idarubicin (4-demethoxy-daunorubicin) in MCF-7 breast tumor cells. Growth inhibition was evaluated using the MTT tetrazolium dye assay, induction of DNA strand breaks was determined by al...
