Erratum: Liu et al., “p130^CAS Is Required for Netrin Signaling and Commissural Axon Guidance”

In the article “p130^CAS Is Required for Netrin Signaling and Commissural Axon Guidance,” by Guofa Liu, Weiquan Li, Xue Gao, Xiaoling Li, Claudia Jürgensen, Hwan-Tae Park, Nah-Young Shin, Jian Yu, Ming-Liang He, Steven K. Hanks, Jane Y. Wu, Kun-Liang Guan, and Yi Rao, which appeared on pages 957–968 of the January 24, 2007, issue, the authors note that the two CAS control lanes in Figure 2d were identical to the two CAS control lanes in Figure 2e: “These were control parts of the same experiment, and thus the CAS control lanes should be the same. The experimental part of Figure 2d showed CAS phosphorylation at Y165, and the experimental part of Figure 2e showed CAS phosphorylation at Y249. For figure panels in the article, it is better to have the experimental part of Figure 2e (CAS Y249 phosphorylation lanes) combined into Figure 2d, with the CAS control lanes shown only in Figure 2d. Figure 2e can then be deleted. These changes in presentation affect no experimental results, interpretations, or conclusions.” In response to concerns raised about Figure 2h, an independent analysis showed no conclusive evidence of image manipulation.
