Figure 2. ATO s uppressed the cell survival and inhibited the protein expression of NAMPT in OSCC cells.
After incubation with varying concentrations of ATO (1, 2, 4, and 8 μM) at 24, 48, and 72 h, (A) the cell survival rate of SCC15 and SCC25 was determined by PrestoBlue cell viability assay; (B) NAMPT protein expression was determined by immunofluorescence. *p<0.05 and **p<0.01vs. untreated cells. Bar=100μm.
