Following pretreatment with AIM V serum-free media at 37°C for 24 h, wtCD26 Jurkat transfectants and parental cells were incubated at 37°C in serum-free media with etoposide or doxorubicin for 24 h. Cells were then harvested and cell cycle analyses were performed with PI staining. Data are representative of three separate experiments.
