Fig. 4: Exogenous addition of 27HC affects leukemic cell growth in vitro and in vivo.

HL60, KG1a, and K562 myeloid leukemic cells are treated with 13 µM Cholesterol or 6.2 µM 27OHChol for 48 h, respectively. A Study overview. B HL60, KG1a, and K562 myeloid leukemic cells were decreased after 27HC treatment. C The exogenous 27HC-treated HL60, KG1a, and K562 myeloid leukemic cells showed a greater percentage of apoptotic cells than did control cells. D The exogenous 27HC-treated HL60, KG1a, and K562 myeloid leukemic cells showed greater ROS production than control cells. E 27HC increases the activity of the ER stress response in HL60 and K562 cells. Data are presented as mean ± SEM. (**p ≤ 0.01 and ***p ≤ 0.001 vs. control; ##p ≤ 0.01 and ###p ≤ 0.001 vs. Chol). (n = 2 independent experiments and 3 total measurements per treatment).
