Apoptosis induced by transient expression of E2. A: Hoechst staining of BHK-21, HeLa, Huh7 and HepG2 cells 48 h after transfection with pSecTagB or pSecTagB/sE2. Note the bright nuclei among cells transfected with pSecTagB/sE2. Photograph is a representative experiment repeated three times (original magnification 400 × ). B: Flow cytometry analysis of PI stained cells 48 h after transfection with pSecTagB or pSecTagB/sE2. The percentage of cells with hypodiploid genomic DNA are indicated on each of the histogram. Results were a representative experiment repeated twice.
