Cytotoxicity of cisplatin and mitomycin C (MMC) is ascribed largely to their ability to generate interstrand crosslinks (ICLs) in DNA, which block the progression of replication forks. The processing of ICLs requires the Fanconi anemia (FA) pathway, excision repair, and translesion DNA synthesis (TLS). It also requires homologous recombination (HR), which(More)
The small nematode Caenorhabditis elegans displays a spectrum of DNA damage responses similar to humans. In order to identify new DNA damage response genes, we isolated in a forward genetic screen 14 new mutations conferring hypersensitivity to ionizing radiation. We present here our characterization of lem-3, one of the genes identified in this screen.(More)
African trypanosomes cause a parasitic disease known as sleeping sickness. Mitochondrial transcript maturation in these organisms requires a RNA editing reaction that is characterized by the insertion and deletion of U-nucleotides into otherwise non-functional mRNAs. Editing represents an ideal target for a parasite-specific therapeutic intervention since(More)
