ANXA5 and infection: Ninety-six hours after treatment with the two agents at their IC50 values, we observed an increase in the percentage of both annexinV-positive–PI-negative cells (indicative of early apoptosis) and annexinV-positive–PI-positive cells (indicative of late apoptosis/necrosis), which was higher after dl922-947 and AZD1775 co-treatment than after dl922-947 infection alone (Figure 2A).
