In our microarray analysis, we observed that expression of a gene, MMP7 (matrix metallopeptidase 7,Matrilysin), exhibited more than a 60-fold increase in the tumor tissue with a distinct spectral signature while only a 3-fold increase in the tumor tissue without the distinct spectral signature, both in comparison to expression levels in normal tissue (data not shown). The gene discussed is MMP7; the disease is neoplasm.
