Eight patients with cancer who were enrolled in clinical trials based on faulty research are suing the scientists involved and their institution, Duke University in Durham, North Carolina. The lawsuit, filed on 7 September, relates to trials based on the work of cancer geneticist Anil Potti, who claimed to have found links between patients' gene-expression profiles and their response to chemotherapy drugs. After other scientists raised questions about the analysis, Potti resigned and five papers were retracted; the trials are now suspended (see Nature 469,139-140; 2011).
