Table 1.

Levels of inhibition of the mRNA and protein expression of different viral genes in cells that expressed M1-TK, C-IE, or M1-IE, as compared to the levels of inhibition of cells that did not express a ribozyme (U373-MG)

HCMV gene	Viral gene class	Level of inhibition, %
		U373-MG	M1-TK	C-IE	M1-IE
IE1 mRNA	α	0	1	8	85  ± 8
IE2 mRNA	α	0	2	7	85  ± 8
US2 mRNA	β	0	1	5	80  ± 6
IE1/IE2 protein	α	0	2	4	88  ± 10
UL44 protein	β, γ	0	1	3	80  ± 5
Glycoprotein B	β, γ	0	0	3	80  ± 9
Glycoprotein H	γ	0	2	1	80  ± 10

Values shown are the means from triplicate experiments. The values of standard deviation that are less than 5% are not shown.
