Direct mapping of melanoma cell - endothelial cell interactions

Endothelial-melanoma Cell Interactions in the Formation of Brain Metastases

Endothelial Cell- Astrocyte Interactions

Recent advances in cell biology open the way for studying aspects of blood-brain bamer (BBB) formation and function that have puzzled investigators since Ehrlich and Goldmann first described the barrier. Although the endothelial cells in the microvessels of all tissues appear to arise from common mesodermal precursors, considerable organ-to-organ variability exists in their ultrastructure and p...

CYTOKINE AND GROWTH FACTOR MODULATION OF CELL CYCLE EVENTS IN HUMAN MELANOMA CELL LINES

Cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. Analysis of the G0/G 1 and S phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. Cy...

Radiation-induced expression of platelet endothelial cell adhesion molecule-1 in cerebral endothelial cells

Background: Radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (AVM) may be used as markers for specific vascular targeting agents. In this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (PECAM-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

Influence of tumor-derived interleukin 1 on melanoma-endothelial cell interactions in vitro.

Human melanoma cell lines that express high constitutive levels of the metastasis-associated marker intercellular adhesion molecule 1 (ICAM-1) were found to secrete interleukin 1 (IL-1) in vitro. Experiments with neutralizing antibodies showed that this cytokine was responsible for their expression of ICAM-1 but not that of two other progression/metastasis markers, Muc-18 and Gp IIb/IIIa. The I...
