Impaired HIV-1 LTR-driven gene expression in nonpermissive cells^a

Virus	Mean log10 EC50 ± SEMb		Pc
	Permissive	Nonpermissive
minHIVGFP	−2.32 ± 0.04	−2.32 ± 0.09	0.9750
HIVGFP	−2.13 ± 0.03	−0.05 ± 0,19	<0.0001

^aThe percentage of GFP⁺ cells or RLU was measured at 72 h after infection. Log₁₀ EC₅₀s were calculated by using a nonlinear regression curve fit of the Prism GraphPad software v.4.0.

^bThe results are expressed as the mean log₁₀ values of calculated the EC₅₀s (n = 3).

^cP values were determined by use of the F-test comparing the best-fit EC₅₀s.
