MMP7 and neoplasm: Supplementary Figure 3A presents comparative data in terms of log2 fold expression vs controls for both normal and tumour samples; the same data is expressed in Supplementary Figure 3B in terms of integer fold expression vs controls. Statistically significant (P<0.05) differences were found between normal and tumour samples for progranulin, gelsolin, kallikrein 10, lysozyme, and MMP7.
