Employing the sophisticated technique of flow cytometry, we observed a remarkable reduction in CD47 expression on the aforementioned tumor cell lines post-infection with oAd-SA, in stark contrast to their untreated counterparts or those exposed to the control virus oAd-ON, with the 4T1 cell line exhibiting particularly pronounced effects as illustrated in Figures 2B, C. The gene discussed is CD47; the disease is infection.
