Potential consequences of epithelial differentiation on virus multiplication. The activities of the E1A N-terminal region are depicted promoting cell proliferation, viral DNA replication and possibly [GT3] epithelial to mesenchymal cell transformation. The activities of the E1A C-terminal region are depicted as possibly [GT4] promoting mesenchymal to epithelial transformation thereby providing a cellular environment that facilitates further steps in virus multiplication.
