TABLE 2:

Volume of subcutaneous tumors that evolved in nude mice after injection of cells.

	Tumor volume (mm3) at given time after injection of cells
Plasmid	At 0 d	At 8 d	At 15 d
Empty	0	0	0
MekEE	0	308 ± 96.2	1009 ± 394.7
ERK1(WT)	0	59 ± 63.9	535 ± 472.9
ERK1(R84S)	0	333 ± 165.7	Killed

Each value represents an average volume of tumors measured in 10 mice.
