Figure 4: FKBP51 knock down promotes enzastaurin citotoxicity of melanoma. A: Graphic representation of cell death values (columns are means and bars standard deviations) of SAN melanoma cells. Cells were transfected with a specific siRNA for FKBP51 and a NS RNA as control, irradiated with a 4 Gy dose and incubated in the absence or the presence of 0.6 μM enzastaurin for 48 h. Cell death was measured by annexin-V staining. Data were obtained from three independent experiments, each performed in triplicate.
