Targeting macropinocytosis in glioblastoma to achieve precision medicine

Tumors must survive microenvironmental stresses, such as nutriment deprivation, low levels of oxygen and anticancer treatments. To do so, tumor cells have developed numerous adaptation mechanisms, and we have recently shown that induction of macropinocytosis is associated with tumor cell survival. In our previous work, we determined that the Galectin-3 (Gal-3)/KRAS/alphavbeta3 integrin complex acts as a driver of macropinocytosis, an endocytic process by which tumor cells are able to engulf large amounts of nutrients from the local microenvironment. In glioblastoma (GBM) cells, which do not harbor mutations in KRAS, we interestingly uncovered the same phenomenon of macropinocytosis…
