Other presentations introduced phosphoglycolate phosphatase as a metabolite repair enzyme required for the coexistence of glycolysis and the pentose phosphate pathway (PPP; by Guido T. Bommer), the role of lactate dehydrogenases (LDHs) in metabolic reprogramming of cancer cells and the necessity to target both isoforms for tumor growth inhibition (by Maša Ždralevič), characterization of metabolism in complex cancer cell populations (by Irena Roci), and metabolic profiling of complex tissues for metabolic phenotyping (by Shonagh Russell). The gene discussed is PGP; the disease is cancer.
