Wild-type drFABP2 nuclear import is independent of β-importin activity.A) Graphical representation of nuclear/cytoplasmic fluorescence intensity ratio (mean ± SD) of wild type Fabp2-EGFP in Caco-2 cells cultured in media with vehicle or in media with 40 μM Importazole. B) Representative single focal planes of Caco-2 cells transfected with wild type Fabp2-EGFP (green) cultured in media with vehicle or in media with 40 μM Importazole. Nuclei counterstaining with DAPI is shown in blue. C) Representative single focal planes of anti-c-Myc signal (gray) in Caco-2 cells cultured in media with vehicle or in media with 40 μM Importazole. Nuclei counterstaining with DAPI is shown in blue. Arrow points to a c-Myc positive nucleus. Bar: 10 μm.
