Amt-87 promotes reversal of HIV latency in a time- and does-dependent manner. (A,B) J-LatA2 cells were treated with 50 μg/ml of Amt-87 for the indicated time periods (A) or the indicated concentrations of the drug for 24 hr (B). The percentages of cells expressing GFP were measured by FACS and plotted. (C) J-LatA2 cells were treated with DMSO or 200 μg/ml Amt-87 for 24 hr. The GFP mRNA levels were measured by qRT-PCR and normalized to those of GAPDH and plotted, with the value in DMSO-treated cells adjusted to 1. (D) Jurkat 2D10 cells were treated with 100 μg/ml of Amt-87 or DMSO for 24 hr and the expression of GFP was analyzed by FACS and plotted. (E,F) The HeLa-based NH1 cells containing an integrated HIV LTR-luciferase reporter gene were treated with 100 μg/ml of Amt-87 for the indicated time periods (E) or 24 hr with the indicated concentrations of the drug (F). (G,H) The NH2 cells expressing Tat were treated with 100 μg/ml of Amt-87 for the indicated time periods (G) or 24 hr with in indicated concentrations of the drug (H). Whole cell extracts were prepared and examined for the luciferase activities. The error bars in all panels represent mean ± SD based on at least three independent experiments.
