The impact of CNHK600-EGFP on MDA-MB-231 cell survival was weaker than that of CNHK600-IL24, at the same MOI of 100pfu/cell, 28.3% of the cancer cells survived after the infection of CNHK600-EGFP whereas only 16.3% remained viable after CNHK600-IL24 infection (Figure 2B, p < 0.05 student’s t-test). Here, IL24 is linked to infection.
