Figure 1From: Photo-activation of the hydrophobic probe iodonaphthylazide in cells alters membrane protein function leading to cell deathINA activated by UV prevents MCF7 propagation. The effect of INA treatment on the propagation of MCF7 cells was measured by a MTS assay. A. Cells were treated with 60 μM INA, 1% DMSO or used as is (control). They were then either exposed to UV light or kept in the dark (no UV). MTS measurements were performed 24 h later. B. Cells were treated with increasing amounts of INA and irradiated with UV. MTS measurements were performed after 24 h. Data are mean ± S.D of seven measurements.Back to article page
