GPx activity in cells transfected with HIV-1 construct (pGD) vs. controls transfected with “empty” construct (pC1)

Cells/construct	Transfection	SeO32−, nM	Activity, units/mg protein
MDCK (n = 9)
pC1	Transient	20	54.3  ± 4.20
pGD	Transient	20	70.8  ± 6.13*
MCF7 (n = 3)
pC1	Stable	100	4.96  ± 2.26
pGD	Stable	100	9.86  ± 1.30**

^*, P < 0.0001, compared with pC1;  

^**, P < 0.05, compared with pC1.
