Table 1. Comparison of earliest transcript detection times in IMR-90 cells and previously published results from HeLa cells.

Gene	IMR-90a	HeLab
E1A	6h	1.5—2h
E1B-19k	12h	8h
E1B-55k	12h	3.5h
52k EP	13h	7—8.5h
E2A	12—13h	2—3h
E3	12h	3h
E4	6—7h	3h
VAII	4h	~3h

Times given are after the initial application of the virus to the cells and are in hours.
