- Immunofluorescent analysis of Ki67 (green) in HeLa cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 1% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed without (left panel) or with (right panel) a Ki67 polyclonal antibody (Product # PA5-16785) at a dilution of 1:100 for at least 1 hour at room temperature, washed with PBS, and incubated with DyLight 488 goat anti-rabbit IgG secondary antibody (Product # 35552) at a dilution of 1:400 for 30 minutes at room temperature. F-Actin (red) was stained with Dylight 554 Phalloidin (Product # 21834) and nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan or a ToxInsight Instrument at 20X magnification.

- Immunohistochemistry analysis of Ki-67 showing staining in the nucleus of paraffin-embedded human breast tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Ki-67 Rabbit Polyclonal Antibody (Product # PA5-16785) diluted in 3% BSA-PBS at a dilution of 1:100 for 1 hour at 37°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

- Flow cytometry analysis of Ki-67 was done on MCF7 cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with Ki-67 Rabbit Polyclonal Antibody (PA516785, red histogram) or with rabbit isotype control (yellow histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

- Figure 5 Representative pictures of DNA repair of telomere DNA double-strand breaks by RAD51-dependent homologous recombination (HR) involving promyelocytic leukemia (PML) bodies, a sign of alternative lengthening of telomeres (ALT) in giant post-DOX cell nuclei undergoing MS cycles with sorting the damage signaling DNA out into the cytoplasm and reconstituting subnuclei free of it: ( A - D ) Days 5-8 post-DOX ( n = 3). The typical HR configurations are boxed, the extranuclear damaged DNA on (D) arrowed. ( E , F ) Reconstitution of subnuclei in two similar cells (DOX-D8-9): ( E ) the extranuclear damaged DNA (arrowed) does not contain PML bodies; and ( F ) FISH with the telomere and cen#2 probes ( n = 3) showing the telomere label cluster in the extranuclear DNA (arrowed). ( G - I ) The release of four repaired subnuclei (boxed) from a defect in the giant mother nucleus (reconstructed in J ); high Ki-67 positivity of the sorted DNA signaling damage by gammaH2AX-label on DOX-D19 ( n = 3).

- Figure 3 Compressive stimulation of ovarian cancer cells causes significant changes in proliferation, cell death, and gene regulation. Cellular proliferation of ( A ) OVCAR3 and ( B ) OVSAHO cells under static and cyclic compressive stress stimulation for 24 h (IHC ki67 expression). Cell death of ( C ) OVCAR3 and ( D ) OVSAHO cells under static and cyclic compressive stress stimulation for 24 h (IHC cleaved caspase 3 expression). (Significance calculated via t -test; n >= 3 experimental replicates, **** p < 0.0001, *** p < 0.001, ** p < 0.01, * p < 0.1). ( E ) Gene expression changes via RT-qPCR for ovarian cancer cells stimulated for 24 h under static or cyclic compressive conditions. A two-fold upregulation is indicated by the dotted line. ( F ) Representative IHC images of OVCAR3 expression of cleaved caspase 3 and ki67 under compressive stress stimulation for 24 h.
