Transcriptome analysis of brain endothelial cells from adult EC-specific Glut1 knock-out mice as compared to wild type controls

To explore the mechanisms through which GLUT1 controls EC function, we compared transcriptomic alterations induced by loss of GLUT1 by performing RNA sequencing analysis on freshly isolated ECs from adult (8 week old) GLUT1EC-/- brains. In adult brains ECs, 1494 genes were differentially expressed between WT and GLUT1-/- ECs but we did not observe compensatory upregulation of other GLUTs. Interestingly, pathway analysis revealed that ECs from GLUT1EC-/- mice were characterized by a robust activation of inflammatory and extracellular matrix pathways.
