Figure 7. Transient overexpression of HtrA2/Omi induces early death in CMV-infected but not uninfected cells.

Figure 7

(A–F) Immunofluorescent images of HtrA2/Omi (A–C) and GFP fluorescence (D–F) following cotransfection of HF with GFP expression plasmid together with empty vector, HtrA2/Omi, or HtrA2S306A expression plasmids. Original magnification ×400. (G) Immunoblot depicting 49 kDa, immature and 36 kDA, mature forms of HtrA2/Omi and HtrA2S306A as well as β-actin control in transfected HeLa cell lysates. (H) Percentage of live HFs at 120 h post cotransfection of GFP expression plasmid with vector, HtrA2/Omi, or HtrA2S306A expression plasmids. (I) Number of viral plaques 10 days following cotransfection of ΔUL37x1 or Towne-BAC DNA (500 ng) with 800 ng vector, HtrA2/Omi, or HtrA2S306A expression plasmids. (J) Number of live (intact) cells in cultures at 48 or 72 h following transfection with Towne-BAC DNA (300 ng) alone or with 333 ng of HtrA2 or HtrA2S306A expression plasmids. (K) Number of live (intact) cells (±range) at 48 or 72 h post transfection with Towne-BAC DNA (500 ng) and 300 ng of vector or HtrA2/Omi expression plasmid with or without addition of 10 µM UCF-101 from 6 h.
