Tumor Cells Interact with Red Blood Cells Via Galectin-4 - a Short Report

The ability of tumor cells to invade and metastasize is relevant to the process of cancer progression and, as such, it represents an obstacle to cancer cure. So far, limited information is available on interactions between circulating tumor cells and blood cells. It is well-documented that galectin-4 is upregulated in many types of tumor cells and is involved in metastasis. Here, we address the hypothesis that tumor cells may interact with red blood cells (RBCs) via galectin-4.
