Tumor M2-pyruvate kinase , a tumor-associated dimeric form of enzyme pyruvate kinase , is commonly elevated in pancreatic cancers.
To achieve this , tumor cells generally overexpress a special glycolytic isoenzyme , termed pyruvate kinase type M (2).
Replacement of glucose by pyruvate in the culture medium lowers glycolytic enzyme activity and prevents proliferation.
Glutamine in a high glucose (HG) environment increased cell proliferation in a dose-dependent manner.
