Overexpression of MMP1, FC = 15.4 (p = 0.05), MMP11, FC = 6.8 (p = 0.03) and MMP13, FC = 12.3 (p = 0.018) genes in breast tumours reached statistical significance, compared to their expression in controls (Supplementary Table S16); while, MMP3 (FC = 6.8, p = 0.214) and MMP14 (FC = 0.48, p = 0.7) genes did not show specific pattern of expression among tumours. Here, MMP14 is linked to neoplasm.
