Olvement of autophagic cell death in tumor suppression. To evaluate the anticancer prospective of 7-E beyond apoptosis, a Cell MeterTM Autophagy Assay was performed to examine distinct autophagosome markers. As shown in Figure 6A, the green fluorescence levels in 7-E-treated (200 nM) cells increased to 247.23 in SCC-9 cells and 147.78 in Apremilast D5 custom synthesis SCC-47 cells when compared with those in untreated control cells. This indicates the induction of autophagy pathway mediators in 7-E-treated HNSCC cells.Cells 2021, 10,10, x FOR PEER Overview Cells 2021,eight of 8 of 17Figure 7-Epitaxol induces apoptosis in SCC-9 SCC-49 cells.
