WNT6 is a novel oncogenic prognostic biomarker in human glioblastoma
Gonçalves, C.; Vieira de Castro, J.; Pojo, M.; Martins, E.; Queirós, S.; Chautard, E.; Taipa, Ricardo; Pires, M.; Pinto, A.; Pardal, F.; Custódia, C.Glioblastoma (GBM) is a universally fatal brain cancer, for which novel therapies targeting specific underlying oncogenic events are urgently needed. While the WNT pathway has been shown to be frequently activated in GBM, constituting a potential therapeutic target, the relevance of WNT6, an activator of this pathway, remains unknown. Methods: WNT6 protein and mRNA levels were evaluated in GBM. WNT6 levels were...
Hypoxia-mediated upregulation of MCT1 expression supports the glycolytic phenot...
Miranda-Gonçalves, V.; Granja, S.; Martinho, O.; Honavar, M.; Pojo, M.; Costa, B.; Melo-Pires, M.; Pinheiro, C.; Cordeiro, M.; Bebiano, G.; Costa, P.BACKGROUND: Glioblastomas (GBM) present a high cellular heterogeneity with conspicuous necrotic regions associated with hypoxia, which is related to tumor aggressiveness. GBM tumors exhibit high glycolytic metabolism with increased lactate production that is extruded to the tumor microenvironment through monocarboxylate transporters (MCTs). While hypoxia-mediated regulation of MCT4 has been characterized, the r...
