Figure 6From: Clathrin-mediated entry and cellular localization of chlorotoxin in human gliomaEffect of chlorpromazine and amiloride on uptake of TM601, dextran and transferrin by glioma cells. Images of U373 glioma cells (treated with: dextran-TX at 1 mg/ml (A), dextran-TX at 1 mg/ml in presence of amiloride 300 μM (E), TM601-488 10 μM (B), TM601-488 10 μM in presence of amiloride 300 μM (F), transferrin-TX at 35 μg/ml (C), transferrin-TX at 35 μg/ml in presence of chlorpromazine 10 μg/ml (G), TM601 10 μM (D) and TM601 10 μM in presence of chlorpromazine 10 μg/ml (H). Direct fluorescence is shown in A, B, C, E, F, G and immunocytochemistry in D, H. The level of staining of both controls, dextran and transferrin, were decreased by amiloride or chlorpromazine, respectively. Data are representative of total n = 3 experiments. Scale bars = 10 μm, magnification 1890 ×.Back to article page
