Levels of inhibition of the expression of viral genes in J774 cells

		EGS (%)
	Viral gene class	SL201	TK112	mPR1	mPR2
mie1 mRNA	α	0	0	1	1
m155 mRNA	γ	0	1	0	1
mPR mRNA	γ	0	2	85 ± 6	7
M83 protein	γ	0	1	1	0
M112 protein	β, γ	0	1	0	0
mPR protein	γ	0	0	86 ± 8	7

The J774 cells were treated with Salmonella SL201 carrying constructs pU6-mPR1 (mPR1), pU6-mPR2 (mPR2), and pU6-TK112 (TK112) and were compared with the levels of inhibition in cells that were treated with SL201 carrying empty vector pU6 (SL201). The values shown are the arithmetic means of three independent experiments performed in triplicate; the values of SD that were less than 5% are not shown.
