DHTKD1 and infection: Specifically, early in infection E1A243R was the most abundant isoform (denoted with • in Figure 3), E1A289R (denoted with * in Figure 3) overall was much less abundant with highest levels observed at 24 h after infection and nearly disappeared by 72 h (top-most band on E1A blots), whereas the 10S-derived E1A171R (denoted with ° in Figure 3) became more abundant later on, particularly in dl309-infected cells.
