Experimental details: Figure 5. Int-C3CNLS does not induce DNA damage or cytotoxicity. ( A ) MTT-based cell proliferation assays were performed to assess effects on cell proliferation rates upon Int expression in human cell lines. HT1080 cells untransfected (HT1080), and FACS sorted GFP + cells obtained after co-transfection of pCMV-EGFP with either pCMVssInt-Ina (INA; expressing inactive integrase) or pCMVssInt-C3CNLS (C3CNLS) were analyzed for the effect on cellular proliferation using the colorimetric MTT assays over the indicated time course. Data show the mean of triplicates and standard deviation of a representative experiment. n = 2. ( B ) Western blot analysis to determine phospho-gamma-H2AX levels to assess DNA damage induced by expression of Int in A549 cells. Cell lysates prepared at time points of 24, 48 and 72 h (post transfection) from A549 cells transfected with pCMVssInt-Ina or pCMVssInt-C3C (expressing Int-C3CNLS) and from control cells treated with the carrier (Lipofectamine2000 Transfection reagent) were subjected to western blot analysis using antibodies against phospho-gamma-H2AX (top panel). UT, untreated cells as negative control; HU, cells treated with hydroxy urea (10 mM for 24 h) as positive control; M, Marker lane. beta-actin was used as loading control (bottom panel). ( C ) Western blot analysis to determine phospho-gamma-H2AX levels to assess DNA damage induced by expression of Int in HT1080 cells. Forty-eight hours post transfection, top and 72 h post transfection, bo

Experimental details: Figure 6 Induction of active caspase-3 and/or gammaH2AX by OA, DTX-1 and -2 in Caco-2 and HT29-MTX cells. Representative images at 10x magnification of Caco-2 and HT29-MTX cells treated 24 h with 150 nM OA ( A ); DAPI staining in blue corresponds to the nucleus. Caco-2 and HT29-MTX cells were treated with increasing concentrations of OA, DTX-1 and -2 for 24 h and were then labeled for detection of active caspase-3 (green) and gammaH2AX (red) by high content analysis ( B ). The percentage of positive cells for active caspase-3 and gammaH2AX was determined using a threshold based on control conditions. Data are expressed as stacked bars representing unlabeled cells (white), active caspase-3-positive cells (green), gammaH2AX-positive (red) and positive for both active caspase-3 and gammaH2AX (orange). n = 3.

Experimental details: (A) The Western blot analysis demonstrates the rescue of gamma-irradiation-induced expression and phosphorylation of ATM, the phosphorylation of H2AX, the expression of p53, Noxa and E2F1 as well as the phosphorylation of CHK1 and 2 in response to the induction of HURP expression by the addition of Dox to the culture media of LNCaP-TetOn-HURP cells. Actin was used internal control for loading and transfer. EMSA demonstrates the inhibition of gamma-irradiation-induced DNA binding activities of the transcription factors E2F1 (B), p53 (C,D) EMSA demonstrates the rescue of gamma-irradiation-induced DNA- binding activity of the transcription factor p53 in response to the induction of HURP expression by the addition of Doxycycline to the culture media of DU145-TetOn-HURP cells. (E) EMSA analysis demonstrated the ability of HURP to inhibit gamma-irradiation -induced DNA binding activity of the transcription factor p53 in LNCap and DU145 cells, whereas in p53- PC3 cells is not detectable compared to positive control. The data are representative of three independent experiments. (F,G) Immune fluorescence demonstrates the inhibition of gamma-irradiation-induced H2AX (red) in response to the induction of HURP expression (green) by the addition of Dox to the culture media of LNCaP-TetOn-HURP cells. The nucleus is stained with DAPI.
