In this study, glycolytic/gluconeogenesis enzymes including alpha-enolase (ENO1), gamma-enolase (ENO2), triosephosphate isomerase (TPI1) and phosphoglycerate kinase 1 (PGK1) were down-regulated in response to tachyplesin I treatment, indicating that tachyplesin I may disrupt the normal energy metabolism process in gliomaspheres through reduced glycolysis, thus contributing to its anti-tumor effect. Here, TPI1 is linked to neoplasm.
