Gene expression patterns obtained from Oligo GEArray Hybridization compared with qRT-PCR. The same RNA samples used for Oligo GEArray hybridization were analyzed by qRT-PCR to four different neuron cultures: WT, WT-OGD (WT after O4/R4), Ngb (Ngb-Tg), Ngb-OGD (Ngb-Tg after O4/R4). Three randomly selected genes, Mmp14 (A), Mt3 (B) and Notch1 (C), were tested. Mean±SD, n=3 per group.
