| In Vitro | HL-60 cells treated with Clofilium (0-20 μM; 24, 48, and 72 hours) lead to suppression of viability and proliferation in both time and concentration-dependent manners. Cell viability decreases significantly in HL-60 cells treated with 2.5 μM to 10 μM of Clofilium[1]. Clofilium (10 μM, 12 hours) induces the proteolytic cleavage of inactive procaspase-3, p34 into its active form, p17 and subsequent cleavage of its substrate PARP at 2 h after exposure to 10 mM Clofilium. However, there is no significant change in expression of Bcl-2 and Bax proteins[1]. Cell Viability Assay[1] Cell Line: HL-60 cells Concentration: 0-20 μM Incubation Time: 24, 48, and 72 hours Result: Inhibited HL-60 cells with IC50s of 6.3 μM for 24 hours, 3.4 μM for 48 hours, 2.4 μM for 72 hours, respectively. Western Blot Analysis[1] Cell Line: HL-60 cells Concentration: 10 μM Incubation Time: 12 hours Result: Induced proteolytic cleavage of caspase-3 and subsequent cleavage of its substrate, PARP, while Bcl-2 and Bax proteins were unaltered. |
