As a result, we observed that in the three parameters, analyzed C6 glioma cells behave like astrocytes, since the results showed increases in glutamate uptake (Figure 3A, p = 0.0087) and GSH content (Figure 3B, p = 0.0155) (after 1 h of treatment) and GS activity decreases (after 24 h of treatment) (Figure 3C, p = 0.0008) compared to the baseline groups. Here, GLUL is linked to central nervous system cancer.
