Fig. 6. Consequences of cell transformation on density-dependent stabilisation of Dlg. Primary BRK cells were grown to 25% (L), 50% (M) or 75% (H) confluence and either incubated (+) or not (–) with the proteasome inhibitor CBZ for two hours. The Dlg protein pattern was then analysed by western blot. The same experiment was also performed in parallel on a BRK cell line stably transformed with HPV-16 E7 and EJ-ras.
