Geno-Tox: Cell Array Biochip for Genotoxicity Monitoring and Classification

초록

In vitro genotoxicity tests detect carcinogens that are thought to act primarily via a mechanism involving direct genetic damage. In this study, we constructed a Geno-Tox cell array chip for genotoxicity testing; eight recombinant bioluminescent bacteria were used to successfully fabricate a Geno-Tox cell array chip. Four well-characterized DNA damage chemicals were selected to determine the capabilities of this Geno-Tox array chip, and each strain of the chip was distinctly responsive, according to the specific mode of genotoxic action. Therefore, this Geno-Tox cell array chip could be implemented to characterize and understand the genotoxic modes of impact; thus, it could be used to provide the genotoxic mechanism of action for new drugs or unknown or newly synthesized chemicals in food and the environment.
