SLC1A2 and central nervous system cancer: Zschocke et al. [31] used rat primary cortical astrocytes and examined the extent of GLT-1 induction 72 hours after DEX (100 nM) treatment, whereas the present study examined the expression of GLT-1 in rat C6 glioma cells that were treated with DEX (100 μM) for 24–48 hours.
