For anchorage dependent clonogenic assays, HER2+ breast cancer BT474 cells were seeded at low density in 6-well plates and allowed to adhere overnight. The next day, olaparib and rucaparib were added at the indicated concentrations. Media and drugs were replenished every three days. After 10-15 days, depending on cell proliferation rate, cells were fixed and stained with crystal violet. Images and graphs indicate the results compared to control condition. Data are mean ± S.D. n.s.: non-significant, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.

Total cell extracts of BT-474 cells treated with increasing concentrations of olaparib or rucaparib were subjected to western blot analysis for PARP-1 and poly ADP-ribose (PAR) expression. β-tubulin was used as loading control. Representative images from two separate experiments are shown.

Serving as positive control were cells fixed 30 min after exposure to 2 Gy IR. Image acquisition was performed with a confocal microscope (Leica TCS SP2) using the 100X objective and a 2X optical zoom and oil immersion. Red: γH2AX foci. Green: RAD51 foci. *P < 0.05 **P < 0.01 ***P < 0.001.

purified PARP-1 and His-XPA were incubated alone ( lane 7 ), with activated PARP-1 (addition of activated DNA and NAD＋, lane 8 ), or in the presence of the PARP inhibitor AG-014699 (lane 9 ). Following the various treatments, His-XPA was pulled down ( IP ) from each sample using cobalt-conjugated magnetic beads.

in vivo suppression of PAR formation by the PARP inhibitor AG-014699 upon induction of DNA damage
Primary human lung fibroblast cells (MRC-5) were pre-treated with the indicated concentration of the PARP inhibitor AG-014699 for two hours. Oxidative DNA damage was induced by 500 µM H2O2 for 10 min and cellular PARP activity was measured by immuno-staining of poly(ADP)-ribose (PAR) (right panels). The in vivo effect of PARP inhibition was compared to cells without DNA damage induction and inhibitor (control) and H2O2-treated cells without inhibitor.
Average nuclear PAR staining intensities of more than 50 cells were statistically analysed by Kruskal-Wallis and the post-hoc Dunn’s Multiple Comparison tests (left panel). Asterisks indicate highly significant (p<1%) differences to H2O2-treated cells without PARP inhibitor. Thick horizontal bars mark medians and error bars the interquartile range.Dr. David Schrmann from University of Base. Rucaparib (AG-014699,PF-01367338) phosphate purchased from Selleck.

| In vitro |
Rucaparib is a potent inhibitor of purified full-length human PARP-1 and shows higher inhibition of cellular PARP in LoVo and SW620 cells. Besides, Rucaparib binds detectably to eight other PARP domains, including PARP2, 3, 4, 10, 15, 16, TNKS1 and TNKS2. [1] [2] The radio-sensitization by Rucaparib is due to downstream inhibition of activation of NF-κB, and is independent of SSB repair inhibition. Rucaparib could target NF-κB activated by DNA damage and overcome toxicity observed with classical NF-κB inhibitors without compromising other vital inflammatory functions. [3] Rucaparib inhibits PARP-1 activity by 97.1% at a concentration of 1 μM in permeabilised D283Med cells. [4] |

| In vivo | Rucaparib is not toxic but significantly enhances temozolomide-induced TGD in the DNA repair protein-competent D384Med xenografts. Pharmacokinetics studies also show that Rucaparib is detected in the brain tissue, which indicates that Rucaparib has potential in intra-cranial malignancy therapy. [4] Rucaparib significantly potentiates the cytotoxicity of topotecan and temozolomide in NB-1691, SH-SY-5Y, and SKNBE (2c) cells. Rucaparib enhances the antitumor activity of temozolomide and indicates complete and sustained tumor regression in NB1691 and SHSY5Y xenografts. [5] |
