A-E The JurkatTat LTR-luciferase cell line was treated with the EC50/4, EC50, EC50*4 of PH01 - PH05, alone or in combination with 300 nM SAHA, 100 nM Chaetocin, 1 µM Ionomycin, or 10 nM PEP005 as indicated. Luciferase activity was measured after 24 h, and the results are presented as percent activation relative to results from PMA treatment (percent activation for the EC50 of each compound are shown here).
