Immunohistochemical Staining of Histone H2AX in Tumors from Treated Mice
Immunocompromised mice were subcutaneously injected with cancerous cell lines and tumors were allowed to establish. Treatments occurred every other day and the studied compound or the equivalent vehicle control administered intraperitoneally for five weeks. Tumor volume and mass were measured two times per week. IHC analysis of sectioned tumor tissues from the MDA-MB-231 study. Each section was subjected to the specified antibody followed by a biotinylated secondary antibody. Detection was done using a DAB Peroxidase HRP Substrate Kit (brown) followed by Hematoxylin counterstaining (purple). Images were obtained using inverted bright field microscopy. Sectioning results are representative of three individual tumors. Scale bar is 50 microns.

(a) E6-1 (Jurkat), dominant negative FADD (dnFADD) Jurkat, & overexpressing BCL-2 Jurkat were treated for 48 hours then stained for Annexin V & PI (b) E6-1 cells were plated & treated with or without the broad spectrum caspase inhibitor ZVAD(oMe)-FMK for 48 hours. Cells were stained for Annexin V & PI. Results were obtained using image-based cytometry with the Y-axis representative of percent of cells positive for Annexin V (green), PI (red), Annexin V & PI (yellow), or negative for both Annexin V & PI (blue). Values are expressed as a mean ± SD from three independent experiments. (c) E6-1 cells were treated for 24 hours with or without the broad spectrum caspase inhibitor ZVAD(oMe)-FMK & the studied compounds, lysed & subjected to Western blot analysis. (d) NHF & NCM460 cells were treated for 48 hours & 72 hours respectively, lysed & subjected to Western blot analysis. Bands were visualized with a chemiluminescence reagent. Images are representative of three independent experiments. Statistical calculations were performed using Two-Way ANOVA multiple comparison. *p < 0.05 vs % viable of Control (DMSO); #p < 0.05 vs % viable cells for groups without Z-VAD(oMe)FMK.
