Monocarboxylate transporters (MCTs) in gliomas : expression and exploitation as...
Gonçalves, Vera M.; Honavar, Mrinalini; Pinheiro, Céline; Martinho, Olga; Pires, Manuel Melo; Pinheiro, Célia; Cordeiro, Michelle; Bebiano, GilBackground. Gliomas exhibit high glycolytic rates, and monocarboxylate transporters (MCTs) play a major role in the maintenance of the glycolytic metabolism through the proton-linked transmembrane transport of lactate. However, their role in gliomas is poorly studied. Thus, we aimed to characterize the expression of MCT1, MCT4, and their chaperone CD147 and to assess the therapeutic impact of MCT inhibition in...
Loss of WNK2 expression by promoter gene methylation occurs in adult gliomas an...
Moniz, Sónia; Martinho, Olga; Pinto, Filipe; Sousa, Bárbara; Loureiro, Claúdia; Oliveira, Maria José; Moita, Luis Ferreira; Honavar, MrinaliniThe gene encoding protein kinase WNK2 was recently identified to be silenced by promoter hypermethylation in gliomas and meningiomas, suggesting a tumour-suppressor role in these brain tumours. Following experimental depletion in cell lines, WNK2 was further found to control GTP-loading of Rac1, a signalling guanosine triphosphatase involved in cell migration and motility. Here we show that WNK2 promoter methyl...

Prognostic value of MGMT promoter methylation in glioblastoma patients treated ...
Costa, Bruno Marques; Caeiro, Cláudia; Guimarães, Inês; Martinho, Olga; Jaraquemada, Teresa; Augusto, Isabel; Castro, Lígia; Osório, LígiaGlioblastoma (GBM) is the most common and aggressive primary brain tumor. The identification of novel molecular prognostic markers of GBM has recently been an area of great interest in neuro-oncology. The methylation status of the MGMT gene promoter is currently a promising molecular prognostic marker, but some controversial data have precluded its clinical use. We analyzed MGMT methylation by methylation-speci...
