Fig. 6. SNX1 localizes to E-cadherin-positive endosomal membranes. MCF-7 cells were fixed and stained for E-cadherin (green), nuclei (DAPI, blue) and SNX1 (red), without (a) or with prior EGF stimulation for 10 minutes (b) or 30 minutes (c) before confocal microscopy analysis. Arrows denote co-labeling of E-cadherin and SNX proteins on small typical endosomal puncta, arrowheads indicate localization of SNX1 to E-cadherin-positive macropinosomes. Note tubular extensions from macropinosomes in (b). Second, third and fourth panels are magnifications of boxed areas shown in respective first panels. Bars, 20 µm for all first panels; 2 µm for all other panels.
