Evaluating microRNA profiles reveals discriminative responses following genotoxic or non-genotoxic carcinogen exposure in primary mouse hepatocytes.

abstract：:Each of the Escherichia coli tester strains in the WP3101P-WP3106P series contains an F' plasmid with a different base substitution mutation within the lacZ gene. Each of the six possible base substitution mutations, therefore, can be assayed with these strains by Lac(+) reversion. We used the strains to characterize ...
