Flow cytometric analysis further showed that AdHTVP2G5-rev-casp3 (MOI = 10) caused a significant delay in S-phase progression with 130.6% increase in the percentage of OVCAR3 cells in the S-phase after the infection for 72 hs(67.8 ± 6.8% for AdHTVP2G5-rev-casp3 vs. 29.4 ± 5.2% for controls). The gene discussed is CASP3; the disease is infection.
