Figure 1. Monitoring response to proteasome inhibitors in MM cell lines using MET or FDG.

Cells were treated for 48 h with either proteasome inhibitor or left untreated before intracellular radioactivity after incubation with MET (top) or FDG (bottom) was quantified using a gamma-counter. Relative uptake of background- and decay-corrected triplicate-samples was expressed as cpm per 1000 cells (mean ± sem; n = 4).
