After the publication of this article [1] it came to our attention that there were some errors in two of the figures:

• 1) In Fig. 3, a number of images were duplicated. Specifically, in Fig. 3a we confused the SK-MES-1 control group with the P group; and in Fig. 3c we confused the A549 control group with the A549 P group. The correct images for the entire Fig. 3 have been included below. We apologise for any inconvenience this might have caused.

• 2) In Fig. 4 we included a Western blot image (Fig. 4a) which was identical with Fig. 1c in another article [2] by our group without making this clear in the figure legend. This has been corrected in the legend below. Again, we apologise for any inconvenienced caused.

Fig. 3

SLC34A2 inhibited migratory and invasive potential after transient transfection for 48h. (a) Millicell chamber assay showed reduced cell migratory ability in SLC34A2-transfected A549, H1299, 95D, and SK-MES-1 cells (P-S) compared with untransfected (Control) and vector- transfected cells (P). (b) Cell migration ratio of those five NSCLC cell lines was assessed by Matrigel invasion assay. (c) Matrigel invasion assay showed depressed cell invasive ability in SLC34A2-transfected A549, H1299, 95D and SK-MES-I cells compared with untransfected and vector- transfected cells. (d) Cell invasion ratio of those five NSCLC cell lines was assessed by Millicell chamber assay

Figure 4 SLC34A2 suppressed tumor growth and lung metastasis of NSCLC in vivo. (a) The expressions of SLC34A2 in A549-P-S, A549-P and A549 cells were confirmed by Western blot. This panel is reproduced from Yang et al. [18]. (b) The concentrations of phosphorous in the supernatant of medium were measured by using a phosphorous measurement kit in A549-P-S, A549-P and A549 cells. (c) Tumor growth curve (each group contained 8 mice). (d) Tumor wet weight. Mice were killed for measurement of tumor weight at 60 days after inoculation. (e) Lungs from mice injected with A549-P-S, A549-P and A549 cells were injected intratracheally with India ink and fixed in AAF solution. (f) The numbers of lung nodules were counted under a dissecting microscope.
