TABLE 1.

Statistically significant experimental variation of the intrahepatic content of HBV replicative forms in mice heterozygous (plus/minus) or homozygous (minus/minus) for the IRF-1 or PKR null mutation^a

Mouse	Ratio for the following mice:
	IRF-1+/−	IRF-1−/−	PKR+/−	PKR−/−
1	78	104	47	68
2	52	91	58	47
3	67	88	36	54
4	48	102	34	71
5	56	107	61	78
6	44	77		74
7	48
Mean ± SD	56.1 ± 12	94.8 ± 11	47.2 ± 12	63.6 ± 11

^aData represent the ratio between the values obtained by phosphorimaging analysis for HBV replicative forms and the transgene.
