Mda-9/syntenin is expressed in the nucleus of uveal melanoma cells.

<p><b>A:</b> Confocal fluorescence microscopy shows nuclear and cytoplasmic localization of mda-9/syntenin in 92.1 cells (upper panels) and OMM2.5 cells (lower panels). An optical section with mda-9/syntenin staining (green) and propidium iodide (red) is shown. A merging image is shown in the bottom quadrants of each panel (original magnification 600×). <b>B:</b> Western blot analysis showing nuclear and cytoplasmic expression of mda-9/syntenin. HDAC1 and β-actin were used as loading controls for nuclear and cytoplasmic extracts, respectively.
