NPPA and glioblastoma: Because of the immunomodulatory properties of the molecules produced through the KP and bioenergetic relevance of this pathway as the source for the de novo synthesis of NAD+, in this study we were focused on the expression of the KP components and their relationship with the gene expressions related to the immune suppression, energy production, angiogenesis, and cell cycle disruption considering mainly three groups: LGG IDHw, LGG IDHm, and GBM.
