Western blotting was carried out according to the Bio-Rad general protocol (BIO-RAD Bulletin 6376 Rev A). Detailed protocol was previously described 17 (link). Primary antibodies were used as follow: rabbit anti-FOXG1 (Abcam, Cambridge, UK, ab18259, 1:1000); rabbit anti-caspase-9 (#9502, 1:1000), mouse anti-caspase-8 (#9746, 1:1000), rabbit anti-caspase-3 (#9665,1:1000), rabbit anti-cleaved caspase-3 (#9661, 1:1000), rabbit anti-AKT (#9272, 1:1000), mouse anti-ERK1/2 (#4696, 1:1000) and rabbit anti-c-Myc (#5605, 1:1000) were all from cell signaling (Danvers, MA, USA); Mouse anti-GAPDH was purchased from TransGen Biotech and mouse anti-α-tublin was get from Ray antibody Biotech (China).
