Figure 1. Inhibition of cell glucose metabolism by FF in the human glioblastoma cells.

A. Cells were treated with various concentrations (25, 50 and 100 μM) of FF. After 48 h, ECAR was measured by the Glycolysis Stress tests. B. GW9662 (10 μM), a PPAR inhibitor, restores FF-induced the inhibition of cell glucose metabolism. *P < 0.05, **P < 0.01. Results are representative of at least three independent experiments.
