The aims of this study are twofold: (1) to determine whether ASCT2 and LAT1 mRNA expression are related to glioma grade and survival; and (2) to characterize ASCT2 and LAT1 expression in low-grade glioma (LGG) and high-grade glioma (HGG). The gene discussed is SLC1A5; the disease is central nervous system cancer.
