Fig. 5. Tube formation by BAE expressing FL-DG or
ßDG. (A) The same
number of cells transfected with vector alone (vectgor) or overexpressing DG
(FL-DG) or truncated ßDG (
ßDG) were seeded on Matrigel. The
phase contrast images of the culture bed at the indicated times are shown. (B)
Levels of endogenous ßDG expression in vector-transfected cells. Membrane
fractions were prepared from cells cultured on Matrigel for the times
indicated. They were analyzed by anti-ßDG western blotting. 10 µg of
protein was loaded on each lane. Anti-actin immunoblot is used as loading
control. The arrowhead indicates the 43kDa ßDG band. Both in (A) and (B),
the results obtained in a single experiment are shown. Similar findings were
obtained on two other occasions.
