This analysis revealed that MMP11 overexpression in PyMTTg; MMP11Tg tumor samples is associated with a significant predicted decrease in ascorbate, glycerophosphocholine (GPcholine), phosphocholine (PCholine), and taurine with a predicted increase in lactate, glycine, glutamate, glutamine, creatine, and the amino acids alanine, valine, phenylalanine, tyrosine, and isoleucine as well as acetate as compared to control samples (Figure 6A). Here, MMP11 is linked to neoplasm.
