Staining of E-selectin ligands on paraffin-embedded sections of tumor tissue
Carrascal, MA; Talina, C; Borralho, P; Gonçalo Mineiro, A; Henriques, AR; Pen, C; Martins, M; Braga, S; Sackstein, R; Videira, PABACKGROUND: The E-selectin ligands expressed by cancer cells mediate adhesion of circulating cancer cells to endothelial cells, as well as within tissue microenvironments important for tumor progression and metastasis. The identification of E-selectin ligands within cancer tissue could yield new biomarkers for patient stratification and aid in identifying novel therapeutic targets. The determinants of selectin ...
E-selectin ligands in the human mononuclear phagocyte system: Implications for ...
Silva, M; Videira, P; Sackstein, RThe mononuclear phagocyte system comprises a network of circulating monocytes and dendritic cells (DCs), and "histiocytes" (tissue-resident macrophages and DCs) that are derived in part from blood-borne monocytes and DCs. The capacity of circulating monocytes and DCs to function as the body's first-line defense against offending pathogens greatly depends on their ability to egress the bloodstream and infiltrate...
Inhibition of fucosylation in human invasive ductal carcinoma reduces E-selecti...
Carrascal, M; Silva, M; Ramalho, J; Pen, C; Martins, M; Pascoal, C; Amaral, C; Serrano, I; Oliveira, MJ; Sackstein, R; Videira, PBreast cancer tissue overexpresses fucosylated glycans, such as sialyl-Lewis X/A (sLeX/A), and a-1,3/4-fucosyltransferases (FUTs) in relation to increased disease progression and metastasis. These glycans in tumor circulating cells mediate binding to vascular E-selectin, initiating tumor extravasation. However, their role in breast carcinogenesis is still unknown. Here, we aimed to define the contribution of th...
