This study also uncovered that sulfated saponin 48 could have a unique antitumor mechanism by selectively targeting multiple glioma metabolic regulators of glycolysis and glutaminolysis, hexokinase 2 (HK2), 6-phosphofructo-2-kinase/2,6-bisphosphatase 3 (PFKFB3), pyruvate kinase (PKM2) and glutaminase (GLS). This evidence concerns the gene PKM and glioma.
