Effects of HIF-1α inhibitor PX-478 on PELs.

Abstract

<p>(<b>A</b>) HIF-1α mRNA levels in BCBL-1 cells 24 hours after treatment with various concentrations of PX-478, normalized to 18S internal control and expressed as fold changes compared to no PX-478 control cells. (<b>B)</b> Proliferation rate of PEL cell lines BCBL-1, BC-3, JSC-1, BC-1, and BC-2 and Burkitt’s lymphoma (BL) cell lines BJAB and CA46 measured using the MTS assay 72 hours after treatment with indicated concentrations of PX-478, expressed as fold changes compared to no PX-478 control cells. (<b>C)</b> Growth rates of the PEL and BL cells treated with 0 or 10 μM PX-478. Error bars represent standard deviations from at least 3 independent experiments. Statistically significant differences between untreated and inhibitor-treated cells are indicated. *<i>P</i> ≤0.05, **<i>P</i> ≤ 0.01.</p
