    (A) p53 signaling is activated either by (i) etoposide or (ii) nulin-3. Etoposide binds and inhibits topoisomerase II, which results in formation of DSB and activates DDR. ATM senses DSB and autophosphorylates. Because SSB are being introduced during DSB repair, etoposide also activates ATR kinase. Both kinases phosphorylate p53 and HDM2, an E3 ubiquitin ligase, which breaks their interactions and leads to p53 accumulation and stabilization and results in expression of p53 target genes. Nultin-3 inhibits HDM2:p53 interactions and thereby induces p53 accumulation. The response is measured using Luc-reporter assay and immunoblotting with Abs specific for ATM pSer1981, ATR pThr1989, p53 pSer15, p53 and p21. (B) Relative expression levels of p53-dependent luciferase reporter. Shown is the mean effect size plus 95%CI after adjustment for multiple comparisons to control using Dunnett’s methods. The mean effect was calculated by linear model of three independent biological replicate transfections/treatments. For each transfection, three technical replicates were measured. Orfs with confidence intervals not overlapping “0” were considered significant hits (p≤0.05). The names of each tested orf are shown on the left.
