SLC2A1 and glioblastoma: Multiple in vitro and in vivo studies have shown decreased tumor cell viability, decreased tumor growth and prolonged survival in the in vivo treatment cohorts [59,60,61,62,65] (Table 1) While studies have not yet demonstrated GLUT1 inhibition by resveratrol in GBM cells specifically, multiple studies in other cell lines like ovarian cancer cell lines [71,72] leukemia cell lines [73] and hypopharyngeal carcinoma [74] have shown that resveratrol can inhibit GLUT1.
