    Figure Lengend Snippet: Validation of the radiation-induced expression of the targets chosen based on the proteomics data using Western blot (A-C) and immunofluorescence (D-F). (A) representatives examples of staining in Western blot; data from a single experiment with anti-EPHA2 and a single experiment with anti-IGF2R is shown. TUBA1A was used as the loading control; lane 1 corresponds to non-irradiated HCC-44 cells grown adherently, lane 2 to irradiated HCC-44 cells grown adherently, lane 3 to non-irradiated A549 cells grown adherently, lane 4 to irradiated A549 cells grown adherently, lane 5 to non-irradiated A549 cells grown as spheroids, lane 6 to irradiated A549 cells grown as spheroids. For better visualization, the contrast of image parts showing EPHA2 and IGF2R staining was reduced; the quantification shown in B and C was carried out using non-modified images. (B, C) Pooled Western blot staining data normalized first to loading control and then separately to the corresponding non-irradiated control (NT) in each independent experiment (N = 4). Each column represents average ± standard error of mean; the immunostained protein names are mentioned in the graph header and the cell lines and treatment conditions below the graph. Statistical significance of paired comparisons (t-test): * corresponds to P < 0.05; (*) corresponds to P < 0.1; ns, not significant. (D-E) Signal intensity established from the microscopy images following IF; the immunostained protein names are mentioned in the graph header and cell treatment conditions prior to lysis below the graph. Each point corresponds to one region of interest in one frame; thick black line shows median and whiskers show interquartile range; data from all independent experiments was pooled (N = 4). Statistical significance of paired comparisons (Mann-Whitney test): *** corresponds to P < 0.001; * corresponds to P < 0.05; ns, not significant.

    Article Snippet: Following blocking with 5% goat serum, the cells were incubated with a rabbit anti-EphA2 monoclonal antibody (1:100; CST, MA, USA) at 4 °C overnight and were immersed in a solution of horseradish peroxidase-labelled secondary antibody for at 37 °C 30 min. After stained with DAB, the cells were dehydrated, cleared and mounted.
