Figure 5. Enhanced inhibition on the expressions of NAMPT protein in OSCC cells induced by ATO combined with FK866.
After incubation with ATO (2 μM) and FK866 (10 nM) for 48 h in SCC15 and SCC25 cells, NAMPT protein expression was detected by immunofluorescence, which was stained with red fluorescence and indicated by arrow (A), and enlarged areas marked by dotted boxes were shown in (B) to display the cytoplasmic distribution of NAMPT. Bar=100μm.
