Inhibitor	EL4, μM	Fold difference inhibitor concentration
		EL4ad + 50 μM NLVS	EL4ad
Lactacystin	4	0.75 ×	1.25 ×
zLLL	0.4	1 ×	3.75 ×
NLVS	8	>6 ×	>6 ×
Epoxomicin	0.03	23 ×	50 ×
Boro-LLL	0.04	12.5 ×	>25 ×
PS-341	0.02	1 ×	2 ×

Cells were cultured in RP10 with varying concentrations of the indicated inhibitors, and the number of viable cells was determined by trypan blue exclusion every 24 h. After 72 h in culture, the concentration of inhibitor necessary to cause an 80% reduction in the number of viable cells relative to control cultures was determined. The fold difference in inhibitor concentration for EL4^ad relative to EL4 cells is indicated.
