We validated the induction of representative genes included in these clusters by QRT-PCR: robo3 and krt20 in the cellular growth and proliferation pathway (Figure 3B-C), scn1a and syt2 in the molecular transport and neurological disease pathway (Figure 4B-C) and grin1 in the neuronal development pathway (Figure 5B). This evidence concerns the gene GRIN1 and nervous system disorder.
