Figure 1From: Overexpression of the ATP binding cassette gene ABCA1 determines resistance to Curcumin in M14 melanoma cellsMelanoma Cells are resistant to Curcumin induced Apoptosis. Fluorescence micrographs of annexin V and propidium iodide stained human melanoma cells show that Curcumin induces only weakly apoptosis in M14 cells as evidenced by a very faint annexin V positive (green) staining. After 24 h of Curcumin treatment only very few M14 cells reach irreversible apoptosis and thereby a propidium iodide positive stage (red).Back to article page
