Alternatively, animals require increased concentration or longer exposure to this compound to elicit the response compared to control animals. In C. Elegans Fluorouracil induces germ cell death, inhibits embryogenesis and inhibits larval growth (depending on dose) in control animals. WBPhenotype:0001649 C_elegans_phenotype_ontology 5 FU resistant
