20.500.12556/DiRROS-20108 Energy metabolism in IDH1 wild-type and IDH1-mutated glioblastoma stem cells a novel target for therapy? Cancer is a redox disease. Low levels of reactive oxygen species (ROS) are beneficial for cells and have anti-cancer effects. ROS are produced in the mitochondria during ATP production by oxidative phosphorylation (OXPHOS). In the present review, we describe ATP production in primary brain tumors, glioblastoma, in relation to ROS production. Differentiated glioblastoma cells mainly use glycolysis for ATP production (aerobic glycolysis) without ROS production, whereas glioblastoma stem cells (GSCs) in hypoxic periarteriolar niches use OXPHOS for ATP and ROS production, which is modest because of the hypoxia and quiescence of GSCs. In a significant proportion of glioblastoma, isocitrate dehydrogenase 1 (IDH1) is mutated, causing metabolic rewiring, and all cancer cells use OXPHOS for ATP and ROS production. Systemic therapeutic inhibition of glycolysis is not an option as clinical trials have shown ineffectiveness or unwanted side effects. We argue that systemic therapeutic inhibition of OXPHOS is not an option either because the anti-cancer effects of ROS production in healthy cells is inhibited as well. Therefore, we advocate to remove GSCs out of their hypoxic niches by the inhibition of their binding to niches to enable their differentiation and thus increase their sensitivity to radiotherapy and/or chemotherapy. glioblastoma stem cells IDH1-mutation energy metabolism true false true Angleški jezik Ni določen Neznano 2024-08-05 16:09:01 2024-08-05 16:09:01 2024-08-07 03:59:20 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Opis vira z dne 12. 4. 2021; str. 1-15 iss. 3 Vol. 10 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-03-22 577.2 2073-4409 10.3390/cells10030705 59095043 https://www.mdpi.com/2073-4409/10/3/705 1 8227bab1-5323-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28037 RAZ_Noorden_Cornelis_J._F._van_2021.pdf RAZ_Noorden_Cornelis_J._F._van_2021.pdf 1 FF27FE913BF90B0ECDA88817C2A3FEF6 ee721d1c570734c630fb16c595b5334538309c5d57baad180a24b093f32f4f82 e7fff8dc-5323-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28039 https://doi.org/10.3390/cells10030705 0 f1a9bd99-5323-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28040 Nacionalni inštitut za biologijo 0 0 0
