In vitro and in vivo analysis of RTK inhibitor efficacy and identification of i...
Martinho, Olga; Oliveira, Renato Silva; Gonçalves, Vera M.; Clara, Carlos; Almeida, José Reynaldo; Carvalho, André Lopes; Barata, João TabordaTreatment for glioblastoma consists of radiotherapy and temozolomide-based chemotherapy. However, virtually all patients recur, leading to a fatal outcome. Receptor tyrosine kinase (RTK)-targeted therapy has been the focus of attention in novel treatment options for these patients. Here, we compared the efficacy of imatinib, sunitinib, and cediranib in glioblastoma models. In the present work, the biologic effe...
Co-expression of monocarboxylate transporter 1 (MCT1) and its chaperone (CD147)...
Oliveira, Antônio Talvane Torres; Pinheiro, Céline; Filho, A. L.; Brito, Maria José; Martinho, Olga; Matos, Delcio; Carvalho, André LopesAntônio Talvane Torres de Oliveira and Céline Pinheiro contributed equally to the study ; Prova tipográfica (uncorrected proof) ; Monocarboxylate transporters (MCTs) have been described to play an important role in cancer, but to date there are no reports on the significance of MCT expression in gastrointestinal stromal tumors (GISTs).

Surgical-site infection risk in oncologic digestive surgery
Castro,Paulo de Tarso Oliveira e; Carvalho,André Lopes; Peres,Stela Verzinhasse; Foschini,Milene Mitsuyuki; Passos,Afonso Dinis CostaSurgical-site infection (SSI) is the most prevalent type of hospital infection in surgical patients and is associated with an increase in hospital stay, costs and morbidity/lethality. The knowledge of the main risk factors for this type of infection is important for the establishment of prevention measures regarding modifiable risks factors. The objective of the preset study was to assess the occurrence of SSI ...
Lymphangiogenic VEGF-C and VEGFR-3 expression in genetically characterised gast...
Oliveira, Antônio Talvane Torres; Reis, R. M.; Afonso, Julieta; Martinho, Olga; Matos, Delcio; Carvalho, André Lopes; Vazquez, Vinícius LimaThis study aimed to assess the distribution of VEGF-C and VEGFR-3 expression in gastrointestinal stromal tumours (GISTs), and to analyse the value of lymphatic vessel density (LVD) in a tumour that is believed to preferentially metastasize through blood vessel conduits. A panel of immunohistochemical antibodies was used to evaluate 51 cases of genetically characterised GISTs: VEGF-C, VEGFR-3, D2-40 (for LVD ass...
