Effects of HEXs-L on Jurkat cell apoptosis by annexin-V-FITC labeling assay. (a) Early and late apoptotic cells (mean of three independent experiments). Cytograms of a representative experiment are shown in (b) control, (c) HEXs-L, and (d) MTX treated cultures. Cells (1 × 10⁵/mL) were treated with HEXs-L (50 µg/mL) or MTX (2 µg/mL) or culture medium (control) for 48 h and then processed for flow cytometric analysis of apoptosis as described in Materials and Methods section. The results in (d) express mean ± S.D. , , and , related to control, by one-way ANOVA followed by Tukey’s posttest.
