Resistance to cortisol-induced apoptosis and antiproliferation in Jurkat and Molt4 cells compared to Daudi and Raji cells.

<p>(A) Jurkat, Molt4, Daudi and Raji cells treated with 100 nM cortisol for 24 hours (middle panels) or 48 hours (bottom panels) were stained with Annexin V/PI and analyzed by flow cytometry. Annexin V single-positive cells were considered apoptotic. (B) Graphical representation of the data displayed in panel A as mean±SD of 3 independent experiments. *p<0.05 <i>vs.</i> untreated cells. (C) Jurkat, Molt4, Daudi and Raji cells treated with indicated concentrations of cortisol for 5 days. Percentages of viable cells after treatment were determined by using trypan blue dye exclusion. Data are shown as mean±SD of triplicate samples. *p<0.05 <i>vs.</i> untreated cells.
