Expression, mutation and copy number analysis of platelet-derived growth factor...
Martinho, O; Longatto-Filho, A; Lambros, MB; Martins, A; Pinheiro, C; Silva, AI; Pardal, F; Amorim, J; Mackay, A; Milanezi, F; Tamber, N; Fenwick, KBACKGROUND: Malignant gliomas are the most prevalent type of primary brain tumours but the therapeutic armamentarium for these tumours is limited. Platelet-derived growth factor (PDGF) signalling has been shown to be a key regulator of glioma development. Clinical trials evaluating the efficacy of anti-PDGFRA therapies on gliomas are ongoing. In this study, we intended to analyse the expression of PDGFA and its...

Maspin expression in normal skin and usual cutaneous carcinomas
Reis-Filho, J; Torio, B; Albergaria, A; Schmitt, FMaspin is a serine protease inhibitor whose gene is located on 3q27. Several lines of evidence point towards its putative role as tumor suppressor gene and angiogenesis inhibitor; however, there are compelling data showing that maspin is also expressed in the nuclear compartment and might be associated with the differentiation of specific cell lineages. No systematic study of maspin expression in normal skin an...
p63 expression in normal skin and usual cutaneous carcinomas.
Reis-Filho, J; Torio, B; Albergaria, A; Schmitt, FBACKGROUND: p63 is a p53 homologue that is mapped to chromosome 3q27. This gene encodes six different isoforms, which have either transactivating or dominant negative effects on p53-reporter genes. It has been described that in contrast to p53, p63 seems not to be associated with tumor predisposition, as neither p63 knockout mouse models nor germline p63 mutations are related to an increased risk of tumorigenes...
Líquido cefalorraquiano no diagnóstico de metástase cérebro-meníngea de melanom...
Rolim,José Augusto B.; Barsottini,Orlando G. R; Prado,Gilmar F.; Nakandakare,Fernando; Reis,Maria L. A. A.; Reis-Filho,J. B.Relatamos o caso de um paciente, de 28 anos, portador de nevo melanocítico gigante congênito(NMGC), com transformação em melanoma e metastátase no sistema nervoso central (SNC). Descrevemos resumidamente as características patológicas de ambas as lesões(NMGC e melanoma), a frequência de malignização do NMGC, os órgãos mais frequentemente acometidos pelas metastases do melanoma - dando ênfase ao acometimento do ...
Deteccion de antigeno del polisacarido capsular de Cryptococcus neoformans en p...
Calvo,B.; Fischman,O.; Castelo Filho,A.; Reis Filho,J.; Del Bianco,R.; Barbosa,R.M.; Zaror,L.Antígeno del polisacárido capsular (Ag PC) de Cryptococcus neoformans fue detectado por la técnica de aglutinación de latex (AL) en LCR y suero de pacientes con Sindrome de Inmunodeficiencia Adquirida (SIDA) y primer episodio de neurocriptococosis, usando como patrón el examen micológico (examen directo y cultivo) de LCR. Se obtuvo una sensibilidad del 100% de AL para detectar AgPC de C. neoformans, el cual por...
