Inactivation of tissue inhibitor of metalloproteinase-1 by peroxynitrite.

abstract：:Neoplastic cells metabolize higher amounts of glucose relative to normal cells in order to cover increased energetic and anabolic needs. Inhibition of the glycolytic enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) diminishes cancer cell proliferation and tumour growth in animals. In this work, w...
