In Fig. 4, the authors replaced and superimposed the T6 band from the first RT-PCR assay with a T6 band from a confirmatory second assay to make Fig. 4 more representative of the data from experiments repeated on three occasions. The gray level of N6, T6 and their corresponding control in first assay is very similar to that of second assay. The bands of N4, T4, N5, T5 and N6 were from the first assay. The expression of ZNRD1 was examined in the esophageal cancer and adjacent non-neoplastic tissues by RT-PCR 3 times, and all data showed that the expression of ZNRD1 was significantly down-regulated in the esophageal cancer tissues as compared with that in the matched adjacent non-neoplastic tissues.

There are errors in the legends of both Figs. 4 and 5. In the legend of Fig. 4, “Detection of ZNRD1 protein in esophageal cancer tissues by RT-PCR” should read “Detection of ZNRD1 mRNA in esophageal cancer tissues by RT-PCR.” In the legend of Fig. 5, “Detection of ZNRD1 protein in different tissues by real-time PCR” should read “Detection of ZNRD1 mRNA in different tissues by real-time PCR.”
