Figure 3e: Co-localization of hnRNPD with hnRNPK and 14-3-3ζ in oral cancer cells. Confocal laser scan microscopy (CLSM) demonstrated nuclear and cytoplasmic expression of (i) hnRNPK (green, FITC) and hnRNPD (red, TRITC) and (ii) 14-3-3ζ (green, FITC) and hnRNPD (red, TRITC) in oral cancer cells (a) SCC4 and (b) MDA1986 cells. Blue colored DAPI was used as nuclear stain. Merged photomicrographs represent the colocalization of hnRNPD with hnRNPK and 14-3-3ζ in oral cancer cells.
