Ribosome Formation is Blocked by Camptothecin, a Reversible Inhibitor of RNA Synthesis

A new drug, camptothecin, has been used to study the regulation of ribosome synthesis in HeLa cells. 5 μM camptothecin inhibits the synthesis of heterogeneously sedimenting nuclear RNA by about 70%. Camptothecin also blocks a specific step in the processing of ribosomal precursor RNA, allowing the c...
