Abstract
A novel high throughput-enabled human cell based screen, Anthem's Genotoxicity screen, was developed to achieve higher specificity for predicting in vivo genotoxins by an in vitro method. The assay employs engineered human colon carcinoma cell line; HCT116 cells that are stably engineered with three promoter-reporter cassettes such that an increased reporter activity reflects the activation of associated signaling events in a human cell. The current study focuses on the evaluation of sensitivity and specificity of Anthem's Genotoxicity screen using 62 compounds recommended by the European Centre for the Validation of Alternative Methods (ECVAM). The concordance of Anthem's Genotoxicity screen with in vivo tests was 95.5% with sensitivity of 95.2% and specificity of 95.7%. Thus Anthem's Genotoxicity screen, a high-throughput mechanism based genotox indicator test can be employed by a variety of industries for rapid screening and early detection of potential genotoxins.
