Supplementary Figures 1 - 11 from PARI Overexpression Promotes Genomic Instability and Pancreatic Tumorigenesis

PDF file - 2404K, Supplementary Figures 1-11; Supplementary Figure 1: Representative micrographs showing a decrease in IR-induced RAD51 foci in PARI-overexpressing 8988T and CAPAN2 cells. Supplementary Figure 2: PARI-overexpressing pancreatic cancer cell line 8988T is hypersensitive to PARP inhibitor ABT-888. Supplementary Figure 3: SupF-based mutagenesis assay showing increased point mutations in 293T cells overexpressing Myc-PARI at high levels. Supplementary Figure 4: Analysis of chromosome morphology in metaphase spreads of 8988T cells, showing that PARI knockdown reduces chromosomal aberrations following exposure to 20ng/ml MMC. Supplementary Figure 5: PARI depletion reduces viability of PARI-overexpressing cells (CAPAN2), but does not affect the cells that do not overexpress it (CAPAN1, HeLa, 293T). Supplementary Figure 6: PARI knockdown leads to a significant increase in the S-phase fraction. Supplementary Figure 7: FACS analysis of 8988T cells treated with HU, followed by release in fresh media. Supplementary Figure 8: PARI depletion in CAPAN2 (pancreatic cancer cells overexpressing PARI) results in HU sensitivity. Supplementary Figure 9: Depletion of PARI by shRNA decreases cellular proliferation when grown in the presence of 20μg/ml doxycyline. Supplementary Figure 10: H&E stain of paraffin-embedded slides showing increased necrosis in xenograft tumors originating from PARI-depleted 8988T cells. Supplementary Figure 11: Model of PARI-dependent DNA repair regulation in pancreatic cancer cells.
