Specific features of endothelial cells in primary tumors

RESUMO: As células endoteliais definem e delineiam todo o sistema vascular...Nesta tese procurámos explorar o papel que o ambiente tumoral exerce sobre as células endoteliais. ... Avaliamos também a capacidade anti-angiogénica de alguns derivados do estrogénio... Em suma os nossos resultados mostram a importância de um controlo rigoroso da regulação transcricional...

Characterization of the glycosylation of human tumor cells

Ovarian cancer is within the most lethal gynecological malignancies in woman. Therefore, many investigators study its biological aspects with the purpose of discovering more rapid diagnostic methods and efficient treatment. Resembling many other tumors, in ovarian cancer, aberrant glycosylation occurs with the appearance of novel or altered carbohydrate structures. These can be terminal motifs, such as the Lewis determinants, or entire carbohydrate sequences, which have been related to tumorigenesis and its outcome.(...)
