Abstract
Status of tumor progression (either remaining in situ, or becoming invasive/metastatic) may be defined largely by subtle interactions ('cross-talk') in a microenvironment formed by interfacing tumor cell and host cell membrane domains (termed 'glycosynapses') involved in glycosylation-dependent cell adhesion and signaling. Functional roles of tumor-associated gangliosides, organized in glycosynapses of three types of tumor cell lines, are discussed. Gangliosides function as adhesion receptors or as 'sensors' that can be stimulated by antibodies, with consequent activation of signal transducers leading to enhanced motility and invasiveness.
