SLC2A1 and epilepsy: Further examination revealed that the alterations in glucose-to-lactate ratios and the levels of GLUT1, VEGFα, and MCT2 proteins in FCDIIa/b versus non-lesional tissues were not influenced by gender (Fig. S2), age of seizure onset (Fig. S3), or the duration of epilepsy (Fig. S4) in either FCDIIa/b or non-lesional subjects.
