Fig. 6. Simple Western and immunofluorescence analyses of Notch intracellular domain (NICD) in PLK1-modulated melanoma cells.
a, b Simple Western immunoblot analysis showing expression of NICD in PLK1-modulated melanoma cells. The relative protein levels normalized to total protein are presented as bar graphs. c, d Relative mean intensity analyzed by immunofluorescence analysis for nuclear localization OF NOTCH (NICD) in PLK1-modulated melanoma cells. The data are presented as mean ± SEM with statistical significance compared to shNS or pcDNA control (*p < 0.05; ****p < 0.0001) in ≥2 biological replicates. For a, c and d, statistical significance was determined via multiple t-tests using the Holm–Sidak method. For b, statistical significance was determined using one- or two-way ANOVA followed by Fisher’s LSD tests.
