Biomarkers predictive of mol. and toxicol. effects are needed to interpret emerging high-throughput transcriptomic data streams. The previously characterized 63 gene TGx-DDI biomarker that includes 20 genes known to be regulated by p53 was previously shown to accurately predict DNA damage in chem.-treated cells. The authors comprehensively evaluated whether the mol. basis of the DDI predictions was based on a p53-dependent response. The biomarker was compared to microarray data in a compendium derived from human cells using the Running Fisher test, a nonparametric correlation test. Using the biomarker, the authors identified conditions that led to p53 activation, including exposure to the chem. nutlin-3 which disrupts interactions between p53 and the neg. regulator MDM2 or by knockdown of MDM2. The expression of most of the genes in the biomarker (75%) were found to depend on p53 activation status based on gene behavior after TP53 overexpression or knockdown. The biomarker identified DDI chems. that were strong inducers of p53 in wild-type cells; these p53 responses were decreased or abolished in cells after p53 knockdown by siRNAs. Using the biomarker, the authors screened ∼1950 chems. in ∼9800 human cell line chem. vs. control comparisons and identified ∼100 chems. that caused p53 activation. Among the pos. chems. were many that are known to activate p53 through direct and indirect DNA damaging mechanisms. These results contribute to the evidence that the TGx-DDI biomarker is useful for identifying chems. that cause DDI and activate p53.
