Figure 4. Structurally related flavonols do not localize to the nucleoli while the fisetin metabolite geraldol does.

Figure 4

Two-photon microscopy of cells treated with 10 μM 3,3′,4′-trihydroxyflavone (a) or quercetin (b) for 30 min show a localization pattern for these flavonols distinct from that of fisetin. Cells treated with 10 μM geraldol for 30 min show a nucleolar localization pattern identical to that of fisetin (c). Excitation wavelength was 780 nm. FOV 90μm × 90μm
