Correction: Cucurbitacin B Induces Apoptosis by Inhibition of the JAK/STAT Pathway and Potentiates Antiproliferative Effects of Gemcitabine on Pancreatic Cancer Cells Free

In this article (Cancer Res 2009;69: 5876–84), which was published in the July 15, 2009 issue of Cancer Research (1), the authors stated that “All animal experiments were in accordance with the guidelines of Cedars-Sinai Research Institute and the NIH.” However, the authors had not specifically received IACUC permissions to inject cucurbitacin into immunodeficient mice to look for its anti-pancreatic cancer activity. The IACUC has concluded that this violation was unintentional and did not result in an animal welfare concern or require reporting to the NIH Office of Animal Welfare. The authors regret this oversight. Subsequent to learning that cucurbitacin was not included in their IACUC protocol, the authors added it and the protocol has been approved.
