MMP12 and neoplasm: Table 1 shows the first 25 up-regulated genes in tumours; among these, we found Defcr4 (defensin-related cryptdin 4), Slc30a2 (a solute carrier specific for zinc transport), Lum (lumican, a member of a small leucine-rich proteoglycan family), Mmp12 (matrix metallopeptidase 12), Igfbp5 (insulin growth factor binding protein 5), Mmp7 (matrix metallopeptidase 7), Nos2 (nitric oxide synthase 2, inducible), S100A8 (S100 calcium binding protein A8 (calgranulin A)) and S100A9 (S100 calcium binding protein A9 (calgranulin B)).
