Abstract:
The expression of the growth factor-inducible JE gene was severely reduced in cells expressing region E1A of human adenoviruses. This reduction was not caused by a decreased stability of JE mRNA but by a reduced transcription rate as determined by run-on transcription experiments. Nevertheless, JE mRNA could still be induced by growth factors, suggesting that intracellular signaling is not blocked but rather that the basal level of JE transcription is repressed by E1A.
