Except for the partial enzyme data that did not meet the screening criteria, most glycolysis-related genes were highly expressed in ovarian cancer, especially solute carrier family 16 member 3 (SLC16A3), enolase 1 (ENO1), and pyruvate kinase M2 (PKM2), which have been confirmed by six studies in the Oncomine database (Figure 1A). The gene discussed is PKM; the disease is ovarian cancer.
