Abstract

Non-equilibrium atmospheric pressure plasma (NEAPP) is a mixture of radicals, electrons, anions, cations and light at near body temperature. Plasma-activated medium (PAM) is realized using NEAPP provided by engineered devices and irradiated to a cell culture medium for a period of 600 s. Glioblastoma cells U251SP cultivated in PAM previously indicated that antitumor effects induced PAM-specific apoptotic cell-death. Metabolomic profiles of a hundred intracellular metabolites were analyzed using capillary electrophoresis mass spectrometry. The metabolomic profiles of the PAM-treated U251SP cells were changed significantly with inhibition of the glycolysis pathway and with enhancement of the pentose phosphate pathway.
