Interestingly, we found that expression of VEGFC and SOD3 positively correlate not only in breast cancer (using two different human data sets) [42] (Bittner Multi-cancer data set, unpublished data, 1 January 2006) but also in kidney and cervical cancers (Bittner Multi-cancer data set) (Figure 8A and Additional file 11: Figure S11). This evidence concerns the gene VEGFC and cervical carcinoma.
