Cell cycle distribution was analyzed by exposing the cells to drugs for 48 h, then staining with PI. a Control, b cells treated with 20 ¦Ìg/ml DIL, c cells treated with 0.25 ¦Ìg/ml DOX, d cells treated with 0.25 ¦Ìg/ml DOX and 20 ¦Ìg/ml DIL, e cells treated with 1 ¦Ìg/ml DOX, f cells treated with 1 ¦Ìg/ml DOX and 20 ¦Ìg/ml DIL.
