      Page 33367, Fig. 7: In panels A,B, and E, the “Ad GFP” should be replaced by “Ad β-gal.” Similarly, in the legend, “Ad GFP” should read “Ad β-gal.” The corrected figure and legend are shown below.

      Figure 7Expression of dominant-negative Akt blocks BMP-2-induced nuclear translocation of BMP-specific Smad. 2T3 cells in chamber slides were infected with 100 m.o.i. Ad β-gal (panels A and B) or Ad DN Akt (panels C and D) for 24 h before incubation with BMP-2 as described under “Experimental Procedures.” The cells were stained with anti-Smad5/1 antibody as described under “Experimental Procedures.” Panel E shows immunoblot analysis of adenovirus-infected cell lysates with anti-HA antibody to demonstrate expression of dominant-negative Akt.
