The analysis revealed that the AD and control lines expressed comparable levels of MAP2, sodium-dependent serotonin transporter (SLC6A4), NMDA receptor subunit NR1 (glutamate ionotropic receptor N-methyl-d-aspartate type subunit 1 [GRIN1]), marker of maturing neurons – RNA binding protein, fox-1 homolog 3 (RBFOX3), and GAD1 (Fig. 2c). This evidence concerns the gene GAD1 and Alzheimer disease.
