Figure 3From: Phosphatidylinositol 3-Kinase dependent upregulation of the epidermal growth factor receptor upon Flotillin-1 depletion in breast cancer cells EGFR endocytosis is not impaired upon flotillin-1 depletion. Staining of endogenous EGFR (green) and LAMP3 (red) after EGF-stimulation (100 ng/ml) for 5 and 30 minutes in MCF7 cells depleted of flotillin-1 (sh-F1-B). Scale bar: 20 μm.Back to article page
