The mean fluorescence intensities (MFI) of PC-3 tumor cells treated with Apo-S-Ac3ManNAz and TRAIL gradually increased 1.6, 5.3, 15.8, 34.2, and 44.3 fold higher than only Apo-S-Ac3ManNAz-treated PC-3 tumor cells at 1, 3, 6, 9, and 24 h, respectively (Fig. 3d). The gene discussed is TNFSF10; the disease is neoplasm.
