Figure 2. SGTA overexpression inhibits HIV-1 release.

Figure 2

HeLa (A) and 293T (B) cells were transfected with WT or Vpu-defective (delVpu) pNL4-3 HIV-1 molecular clones with or without FLAG-tagged SGTA expression vector. One day posttransfection, cell and viral lysates were prepared and subjected to western blot analysis with HIV-Ig to detect the Gag precursor Pr55Gag (p55) and the CA protein p24, or anti- FLAG to detect FLAG-tagged SGTA, or anti-tetherin, or anti-Vpu antisera. (C,D) virus release efficiency (VRE) was calculated as in Fig. 1B, and VRE was set to 100% for no SGTA controls. (E,F) the ratio of p24 to p55 in cell lysates was calculated and set to 100% for no SGTA controls. Data shown are ± SD from three (D,F) or four (C,E) independent experiments. P values (two-tailed paired t-test): *p < 0.05, **p < 0.01, ***p < 0.005, ****p < 0.0005.
