Nine classical mammalian FOXO target genes involved in cell cycle regulation (Ccng2, Cdkn1a, Cdkn1b, Rbl2), DNA repair (Gadd45a), apoptosis (Bim), stress response (Cat, Sod2) and insulin signalling (Eif4ebp1) were selected and their mRNA levels in a differentiated mouse neuroblastoma cell line (N2A) following ethosuximide exposure were then measured using qRT-PCR. The gene discussed is GADD45A; the disease is neuroblastoma.
