Repression of HPV18 mRNA in cells constitutively expressing HPV16 E6/7 mRNA

	% of mock*
	HPV18 E6/E7	HPV16 E6/E7
LXSN-4	0.4	NA†
HPV16 E6/7-D	1.0	98.2
HPV16 E6/7-N	0.8	220

^*HPV E6/7 mRNA prepared 24 h after infection with the E2 virus was measured by Northern blotting, normalized, and expressed as the percentage of the signal from mock-infected cells. The average of two different experiments is shown.
