Correction: Long Noncoding RNA HOTAIR Regulates Polycomb-Dependent Chromatin Modification and Is Associated with Poor Prognosis in Colorectal Cancers Free

In this article (Cancer Res 2011;71:6320–6), which appeared in the October 15, 2011, issue of Cancer Research (1), the P value of liver metastasis in Table 1 is incorrect. It should be 0.006.

In addition, the second sentence in the Results section is incorrect. The correct version is listed below. The authors regret these errors.

HOTAIR levels in cancerous tissues were significantly higher than those in the noncancerous tissues (P = 0.002; Fig. 1A).
