    <p>(A) LNCaP cells were treated at the indicated doses for 24 hours and proliferation was assessed. (*): P value <0.05 (Student’s t-test) vs control cells. (B) Effect of cisplatin treatment on DNA fragmentation of LNCaP cells. LNCaP cells were treated with 50 µM cisplatin for 0, 4 and 24 hours. Cellular DNA was isolated and subjected to agarose gel electrophoresis.</p

    <p>(A) Coimmunoprecipitation of Bax and Ku70 following or not irradiation. No Bax- Ku70 coimmunoprecipitation was found at time 0 in not irradiated U7-nClu cells compare to U7 control cells. No coimmunoprecipitation of Bax and Ku70 was observed in all irradiated cells both at 4 hrs (not shown) and 24 hrs. (B) Defective expression of KU70 in nCLU-transduced cells. Note the upregulation of Rad17 protein following irradiation of nCLU-LNCap.</p

    <p>(A) (Top) Antisens sequence position to induce exon 2 skipping. (Bottom) Structure of the pHIV-1-U7-nCLU. U7snRNA including antisens sequence is placed under the control of its own promoter and its regulating domains 3′. SmOPT: sequence indicates the Sm protein binding site. LTR : long terminal repeats. (B) U7 vector integration in transduced LNCaP cell genome. Curves represent qPCR amplification of U7-nCLU genomic DNA in different transduction conditions (middle curves). Human β-actin amplification corresponded to positive control (Top curves) and genomic DNA of non transduced cells was used as negative control. (C) (Top) mRNA from transduced LNCaP cells with U7-nCLU vector was analyzed by RT-PCR at 3 weeks posttransduction. The 344 bp and 218 bp bands correspond to sCLU and skipped form nCLU mRNA respectively without alteration of the sequence. Controls were from RNA of LNCaP alone or LNCaP transduced with U7-control. (Bottom) Relative mRNA expression levels determined by densitometry. βactin used to normalize changes in specific gene expressions. (D) DNA sequence of the 218 bp band showed skipping of exon 2.</p

    <p>FACS analysis was performed at 0, 2 and 4 hours after 10 min UV-C cell exposure. Cell death was assessed using propidium iodide (PI)/annexin V staining. The red rectangle surrounds PI−/Annexin V+cells. Histogram represent % of dead cells in each condition. Results are means +/− s.e.m. from 3 individual experiments. (*): P value <0.05 (Student’s t-test).</p
