Interactions between molecules on the surface of tumor cells and those on the target organ endothelium play an important role in their arrest in an organ. Galectin-3 on the lung endothelium and high affinity ligands poly-N-acetyllactosamine (polyLacNAc) on N-oligosaccharides on melanoma cells facilitate such interactions. However, to extravasate and(More)
Secreted galectin-3 often gets incorporated into extracellular matrix and is utilized by cancer cells for spreading, movement, and metastatic dissemination. Here we investigate molecular mechanisms by which galectin-3 brings about these effects and compare it with fibronectin. Imaging of cells spread on fibronectin showed stress fibers throughout cell body,(More)
